Come mai hanno pensionato il PAD 38b? Leggevo che STS-116 è stata l'ultima ad utilizzarlo
No, l'ultimo lancio sulla 39B (penso tu intenda questa) sarà quello della missione per Hubble nel 2008 (STS-125) fino ad allora non si potrà mandare in pensione perchè in quella missione ci sarà la necessità di avere due shuttle contemporaneamente in rampa, il secondo servirà da soccorso (STS-325) per eventuali problemi della missione che non potrà utilizzare la ISS come base di emergenza. Dopo quel lancio inizieranno i grossi lavori per convertire la rampa ai lanci del vettore Ares-I che porterà in orbita il CEV, con i primi voli (test) previsti nel 2009. I lavori comunque inizieranno prima di allora, si dovrenno intanto costruire i 4 enormi piloni-parafulmine intorno alla rampa alti 300metri ciascuno. I lavori invece che dovranno per forza aspettare la fine dell'utilizzazione per il programma Shuttle saranno lo smantellamento della parte mobile della rampa (quella che avvolge lo Shuttle prima del lancio per intenderci), la costruzione del sistema di fuga per gli astronauti (una specie di montagna russa) e la modifica dei sistemi d'accesso al vettore.
Solo una correzione alla spiegazione corretta di Alberto, l'ultima missione dal pad B del LC39 (Launch Complex 39) è effettivamente stata l'STS-116, ma non verrà decommisionata prima del settembre 2008 (Atlantis) perchè il Discovery dovrà essere pronto per l'eventuale missione di salvataggio, STS-325 (tutte le missioni di salvataggio post-Columbia sono numerate 3XX con le ultime due cifre rimanenti indicanti il volo).
Quindi l'Atlantis decollerà dal pad A (come tutte le rimanenti missioni), mentre Discovery dovrà essere pronto sul pad B, e questa sarà anche la seconda ed ultima volta che due Shuttle o, in gergo NASA, due "stack" (il complesso orbiter+ET+SRB) saranno presenti contemporaneamente sui due pad.

Modification implemented on SRBs following debris concern
By Chris Bergin, 2/9/2007 6:40:52 AM
http://content.nasaspaceflight.com/library/1016/D1(5).JPG
NASA's Program Requirements Control Board (PRCB) have ordered a modification - within existing certification - to the Solid Rocket Boosters (SRB), following a debris strike during STS-116's launch last December.
The debris, which was insulation flying off the aft of the left SRB, impacting on Discovery, was "greater than defined allowable (0.0002 lbm)" - and work is being carried out in the Vehicle Assembly Building (VAB) to trim the area which shed the material on Atlantis' boosters ahead of STS-117.[...]

Atlantis' booster requires troubleshooting
By Chris Bergin, 2/13/2007 10:26:10 AM
United Space Alliance (USA) engineers are working on a troubleshooting plan, following 'erratic' chamber pressure readings on the right hand SRB (Solid Rocket Booster).
The issue - which was noted last night without specifics - is still expected to delay rollout by 24 hours, although engineers are looking at possibly continuing their evaluations on the launch pad. However, two of the IPRs (In Process Reviews) are officially classed as constraints to rollout.
The issues have stopped the retraction of all the platforms that surround Atlantis and the STS-117 stack inside High Bay 1 of the Vehicle Assembly Building (VAB), with troubleshooting re-starting on Tuesday morning.
'Rollout of STS-117 to the Pad may be delayed 24 hrs due to IPR?s 0062 and 0063 on the RH SRB (see IPR status directly below) - the schedule is under review,' noted the expansive Launch Operations report for Tuesday.
'C Platform retraction was completed yesterday. E Platform retraction is on hold for IPR troubleshooting access requirements in the SRB forward skirt area.
The list of IPRs were listed after the Integrated Space Shuttle Vehicle interface test was conducted on Atlantis and the STS-117 stack.
'IPR-0061: RH (Right Hand) aft separation motor 'no-go' should be 'go' - will close as GSE cable not mated properly,' listed the Launch Ops report.
'IPR-0062: Pitch and yaw indicator went from 'on' to 'off' to 'on'. The constraint is to S0007 (Launch Countdown). This IPR may be related to IPR-0063. This IPR is a constraint to rollout.
'IPR-0063, The RH SRM (Solid Rocket Motor) chamber pressure went erratic - could be related to IPR-0062. This IPR is a constraint to stray voltage testing, platform retraction, and rollout. Power up troubleshooting was performed last evening to try to isolate the problem to the chamber pressure OPT (Operational Pressure Transducer) in the RH forward skirt area.
'Initial indications are that the transducer is faulty, however further troubleshooting will have to be performed to ascertain the condition of the cabling between the Monoball and the aft IEA, and the cabling between the aft IEA and the OPT in the forward skirt.'
Troubleshooting the chamber pressure issue was ceased last night due to lack of manpower and a lack of adapter cables required for testing. This has resumed on Tuesday morning.
'IPR-0064, RH SRB camera recorder #2 was 'off' and should've been 'on'. Troubleshooting is complete to date; this may be a camera recorder card issue, and a camera/recorder R&R is possible. This IPR is not a constraint to roll out to the pad.
Another issue was also noted via an electrical bus error, which is also a constraint to rollout. However, this issue is not fully understood as to the culprit of the fault, which could lie anywhere between the RH SRB and the aft of Atlantis herself.
ATK's Tuesday update confirmed the issues with the RH SRB, but noted that plans are in work to carrying out evaluations at the launch pad.
'S0008, Shuttle Interface Test, is worked as far as possible. Stray voltage tests will follow IPR 117V-0063 resolution. SSV Rollout to Pad A call-to-stations are scheduled for 0300 hours on Wednesday to Thursday at the same time,' noted the ATK Quick Look report for Tuesday.
'IPR 0063 was written against the RH SRB electrical measurement that had an erratic reading. Troubleshooting points toward a bad OPT. Plans to R&R the OPT at the pad are in work.'
Atlantis' processing has enjoyed a smooth flow until thes issues with one of her boosters, and such hiccups can be expected in any pre-launch work. There remains plenty of contingency time in the flow towards a March 15 launch date, regardless of a delay with rollout.
In other pre-launch news, a bent bracket has caused a slight delay in the preparations of Atlantis' S3/S4 integrated truss payload at the launch pad.
'The S3/S4 integrated truss payload transfer from the canister to the PGHM (Payload Ground Handling Mechanism) was delayed yesterday due to a bent bracket on one of the payload support beam drive motors,' added the expansive Launch Operations report for Tuesday. 'The Z drive motor was removed last night and the PGHM moved aft to close the canister doors in anticipation of poor weather.
'An engineering review of a proposed solution will need to be performed along with the repair on 1st shift today. It is estimated that everything could be ready to support a payload transfer around mid 1st shift today. Canister lowering and transfer to the Canister Rotation Facility (CRF) will follow.'
Atlantis heads for launch pad

Posted: February 15, 2007
Editor's note: Rollout was successfully completed at 3:09 p.m. with the platform's lowered onto the pad pedestals.
Lumbering along with a top speed of one-mile-per-hour, space shuttle Atlantis emerged from Kennedy Space Center's mammoth Vehicle Assembly Building this morning for the trek to the newly refurbished launch pad 39A.
The trip, which should take about six hours, began at 8:19 a.m. EST.
http://www.spaceflightnow.com/shuttle/sts117/070215rollout/rolloutnasa.jpg
Atlantis spent eight days inside the 52-story VAB being attached to its external fuel tank and twin solid rocket boosters atop a mobile launching platform. The stay was extended a day while technicians examined erratic readings from a pressure sensor inside the right-hand booster. A new sensor will be installed at the launch pad.
Today's rollout to the pad travels along a three-and-a-half-mile route known as the crawlerway. The space-age road is 130 feet wide -- almost as broad as an eight-lane highway. Two 40-foot-wide lanes are separated by a 50-foot-wide median strip. The average depth is seven feet.
The Apollo-era crawler-transporter carrying Atlantis is powered by 16 traction motors that feed from two 2,750 horsepower diesel engines. Two 1,065 horsepower diesel engines are used for jacking, steering, lighting and ventilating. The transporter consumes 126 gallons of diesel fuel in each mile it travels from the VAB to the pad.
The overall weight of the transporter, mobile launch platform and shuttle is 12 million pounds.
About 30 workers are needed to operate the crawler, including three drivers -- a prime and backup in the front cabin and one in the rear -- a jacking and leveling operator, a control room operator to run crawler systems and talk with the Launch Control Center, two electricians, two electronic technicians and four diesel mechanics for starting, monitoring and shutting down the transporter's engines. The other team members are mechanics watching over the roll and helping with the platform's docking to the launch pad.
NASA anticipates the platform will be lowered onto the pad pedestals around 3 p.m. today. That will commence the methodical process of hooking up the crew module access and hydrogen vent arms extending from the launch tower, as well as electrical, propellant, communications and other lines between the ground systems and mobile platform.
The gantry-like Rotating Service Structure will be moved around Atlantis, allowing the payload bay doors to be opened this weekend in preparation for loading the mission cargo aboard the shuttle.
The payload is the Starboard 3/Starboard 4 combined truss structure for the International Space Station. The power-generating module will be attached to the station and its giant solar wings unfurled during the upcoming mission. The truss will provide a fourth of the station's power and allow the continued expansion of the outpost.
Liftoff remains targeted for March 15 at about 6:42 a.m. EDT. This 28th flight of Atlantis begins a busy year for the shuttle program in which five missions are planned, all dedicated to station assembly.
Atlantis will be pad 39A's first launch in over four years. The complex underwent a major refurbishment, enabling it to support all remaining shuttle flights planned through 2010.

Hail storm damage grounds Atlantis
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: February 27, 2007
A sudden, explosive thunderstorm Monday battered the shuttle Atlantis' external fuel tank with wind-driven, golf ball-sized hail, causing extensive damage to the tank's protective foam insulation. NASA managers said today engineers will have to move the shuttle back to the Vehicle Assembly Building for repairs, delaying launch on a space station assembly mission from March 15 to late April.
http://www.spaceflightnow.com/shuttle/sts117/070227hailpix/hailpic1.jpg
With wind gusts as high as 62 mph at launch complex 39A Monday, early estimates indicated some 7,000 visible hail dings or blemishes in the orange insulation, mostly around the top of the external tank. John Chapman, external tank program manager at the Marshall Space Flight Center, said today not all of those dings will require repairs. But initial estimates have identified "hundreds" of sites that will require sanding to smooth over or foam "pours" to fill in deeper pits.
In addition, at least three so-called ice-frost ramps on the upper part of the tank were damaged and two dozen or so shuttle tiles showed signs of minor surface damage.
"This constitutes, in our evaluation, the worst damage that we have ever seen from hail on the external tank foam," shuttle Program Manager Wayne Hale told reporters today. "We have had hail a number of times in the past, hail is not unusual in Florida. ... But usually the hail is quite small and rarely causes damage.
"This was large, wind-driven, damaging hail. It is very clear a number of these areas need to be repaired. There is not access on the launch pad so we will be required to move the space shuttle back from the launch pad to the Vehicle Assembly Building."
Launch director Mike Leinbach said today the 3.2-mile trip from pad 39A to the VAB likely will get underway Sunday morning. Once the shuttle is back in the cavernous VAB, where engineers can position access platforms around the tank, Hale said a more accurate assessment of the damage will be made.
In the meantime, "we do not believe we can make the launch window for the March launch of Atlantis," Hale said. "We have a fairly high degree of confidence we can repair this at the Kennedy Space Center. Most likely that would lead us to a launch of Atlantis and her crew ... after the Russian Soyuz changeout."
March 25 marked the end of the March launch window to give Atlantis' crew time to carry out a space station assembly mission and to undock in time for the planned April 7 launch of a Russian Soyuz spacecraft carrying the station's next full-time crew and American space tourist Charles Simonyi.
Outgoing station commander Mike Lopez-Alegria, Mikhail Tyurin and Simonyi are scheduled to return to Earth on April 19 or 20, depending on how much daylight the Russians want for landing. Current agreements between NASA and the Russian space agency require a few days of separation between shuttle and Soyuz missions because of crew rest and other issues.
Assuming a Soyuz landing on April 19 or 20, the next shuttle launch window would open around April 21 or 22 and extend a full month. The next shuttle launch window after that opens June 9.
If a detailed assessment of Atlantis' tank shows the hail damage can, in fact, be repaired inside the Vehicle Assembly Building, Hale said he was optimistic about a late April launch attempt.
"The bottom line here is we will have to roll back to the VAB for repairs," Hale said. "We believe ... it will probably be about a month before we can talk about being back in a launch posture, sometime in late April."
But Chapman said that assumes the damage can be fixed by "sand-and-blend" techniques or by pouring foam into damaged areas and then sanding and smoothing it over. If foam has to be sprayed across wider areas, engineers likely would have to carry out tests to verify the technique can be accomplished with the tank in a vertical orientation in the VAB. And that could take additional time.
But based on the preliminary assessment, "we don't see anything that looks irreparable," he said.
If it turns out the tank cannot be safely repaired in Florida, NASA has the option of switching Atlantis to a tank slated for use in June by the shuttle Endeavour. But that tank is not scheduled to arrive at the Kennedy Space Center until April 10 and it typically takes two months to complete preparations and checkout. In that case, the flight likely would slip into the June launch window.
But Hale said he was optimistic it won't come to that. He also believes the long-term effects of the slip from March 15 to late April will be minimal when all is said and done. While the next few flights would face delays of up to several weeks, "I still believe we have a very strong probability of flying five flights this calendar year." http://www.spaceflightnow.com/shuttle/sts117/070227delay/

Hail damage to Atlantis and ET - ROLLBACK
By Chris Bergin, 2/27/2007 8:49:18 AM
Engineers are evaluating observed damage to the top of the External Tank (ET-124) - which is set to fly with Atlantis on STS-117 - caused by a hail storm late on Monday.
The damage is visible to the SOFI foam on the top of the LOX tank and an Ice Frost Ramp (IFR), and with up to 7000 areas of damage, rollback of the STS-117 stack into the Vehicle Assembly Building (VAB) for repairs has now been confirmed.
Atlantis herself also suffered 27 dings on her left wing. New launch date is NET April 22.
Ancora, sul danno all'ET:
Atlantis launch date slips to end of April due to damage
...
Earlier, it was hoped that the March launch window could be saved, although that was based on the damage to the tank being classed as 'minor'.
'Minor ET repairs in VAB - Possibly make the end of the March 25th window. Major ET repairs in VAB - Might be able to make the April 23rd - May 24th window. R&R (Remove and Replace) ET with the 118 tank - STS-117 will launch in July and STS-118 will move to August 26th,' added a pre-Lockheed Martin (MAF) assessment memo.
However, the possibility of keeping to the March timeline was removed following a lunch time meeting with ET engineers and managers, which noted an updated three pronged plan.
'The March launch window is no longer an option. Currently KSC is looking at three options. The first is a 21 day VAB repair period without tank removal. This option allows the first launch attempt at the beginning of the April/May window (22 April),' added a NASA memo at 1pm Houston time.
'The second option has the tank demated and transferred to the VAB storage cell for repair. This options extends the VAB period but allows a first attempt at the end of the April/May window(20 May). The last option is a tank R&R. ET-117 is expected here mid April. This option has the first attempt 15 June.

Shuttle Atlantis rolls off launch pad for repairs
BY JUSTIN RAY
SPACEFLIGHT NOW
Posted: March 4, 2007
Battered by an intense hail storm six days earlier, space shuttle Atlantis retreated off launch pad 39A and returned to the cavernous Vehicle Assembly Building on Sunday to undergo thorough inspections and repairs.
http://www.spaceflightnow.com/shuttle/sts117/070304rollbackpix/05.jpg

Perched atop a mobile launching platform, the shuttle was hauled three-and-a-half miles back to the 52-story building by an Apollo-era transporter. The trip began at 8:47 a.m. and was considered complete at 5:49 p.m. EST when the platform was placed on pedestals in the VAB.
Crews immediately began work to place access platforms around the shuttle for an upclose examination of the hail strikes. The methods for fixing the pitted insulating foam on the external fuel tank and the time needed to carry out such work will be determined in the coming days.
A severe storm swept over pad 39A around 5 p.m. Monday and dropped hail the size of golf balls, causing thousands of chips and divots in the orange foam covering the tank.
The heatshield on the orbiter's left wing also experienced wind-blown hail impacts. Initial examinations at the pad revealed more than two dozen of the ship's black tiles sustained surface damage.
"This constitutes, in our evaluation, the worst damage that we have ever seen from hail on the external tank foam," said Wayne Hale, the shuttle program manager. "We have had hail a number of times in the past, hail is not unusual in Florida. ... But usually the hail is quite small and rarely causes damage.
"This was large, wind-driven, damaging hail. It is very clear a number of these areas need to be repaired."
The lack of adequate access to the widespread damage at the launch pad meant NASA had no choice but return the shuttle to the Vehicle Assembly Building.

Atlantis had been slated for launch just before sunrise March 15 to deliver and install a 17.5-ton power truss module at the International Space Station. But the trip back to the VAB will cause the shuttle to miss its window to fly before previously-scheduled Russian Soyuz spacecraft traffic at the station.
A Russian Soyuz capsule with the Expedition 15 long-duration resident crew is scheduled for blastoff from Kazakhstan on April 7. The outgoing Expedition 14 crew returns to Earth aboard its Soyuz on April 19.
Since station controllers require at least a few days between the departure of one craft and the arrival of the next, Atlantis won't launch before late April. An official target launch date has not been established.
Rollbacks have been relatively rare occurrences over the life of the shuttle program. NASA said that Sunday's move was the 18th since 1983, with the majority caused by technical problems. A handful were prompted due to the threat of tropical weather and hurricanes.
Two previous rollbacks were required to repair external tank foam. Woodpeckers drilled nearly 200 holes on the tank for shuttle Discovery's STS-70 mission in 1995 and hail caused damage before Discovery's STS-96 flight in 1999.

Quando l'ho visto in laboratorio ho detto, ma guardate qui, questi in 12 giorni fanno una roba del genere, qui son tre anni per mandare su un cubo di 30cm e non abbiamo ancora niente di funzionante :D

STS-117 rollout update - Boosters in train accident
By Chris Bergin, 5/1/2007 4:08:50 PM
The rollout of Atlantis and her repaired External Tank is likely to take place on the 16th of this month, following the latest ET-124 repair estimates. Engineers are also half way through the process of removing Atlantis' main engines for inspection.
Meanwhile, booster segments - set to fly on a future mission - were involved in a train derailment while en-route to the Kennedy Space Center (KSC). The train is now back on the tracks and heading to Florida.
non commento ulteriormente sulle sfighe di questa missione.. ;)

anche se l'incidente riguarda più che altro le prossime missioni, STS-120 e 122..

Atlantis returns to the pad
http://www.spaceflightnow.com/news/images/ni0703/04atlantisvab.jpg http://www.spaceflightnow.com/news/images/ni0705/15rollout.jpg
The space shuttle Atlantis returned to launch pad 39A Tuesday for its delayed flight to the space station. The 3.5-mile trip took about seven hours to complete. Atlantis had been in the Vehicle Assembly Building for the past two months undergoing hail-damage repairs on the external tank foam.

Space shuttle launch countdown begins tonight
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: June 5, 2007
Shuttle engineers are gearing up today for the start of the shuttle Atlantis' countdown to blastoff Friday on a mission to deliver a new set of solar arrays to the international space station. With forecasters predicting a 70 percent chance of good weather, the countdown is scheduled to start at 9 p.m. this evening, targeting a launch attempt at 7:38:02 p.m. Friday.
"All our systems right now are in great shape, we're tracking no constraints that are show stoppers," said NASA Test Director Steve Payne. "The teams are ready and everybody's eager to launch. We're looking forward to a safe and successful assembly mission."
Shuttle weather officer Kathy Winters said today she expects a 70 percent chance of acceptable weather Friday, Saturday and Sunday, with the only concern being possible showers or thunderstorms in the area. The weather at emergency runways in California, Spain and France also is expected to be good.
"We do expect to see some afternoon thunderstorms in the area on launch day but by launch time, all that weather should move inland with the sea breeze," Winters said. "So for the coast here, the weather looks reasonably promising for launch."
Atlantis originally was scheduled for liftoff on mission STS-117 on March 15, but the flight was put on hold after a freak hail storm Feb. 26 that caused extensive damage to the protective insulation on the shuttle's external fuel tank. Repairing the tank was a major technical challenge, but NASA managers say they are satisfied the repairs will stand up to the thermal and aerodynamic rigors of launch.
"We are relieved that we're finally there," Payne said. "It's been a long waiting period and as you probably know, whenever you're ready to go and you have to stop and wait for a few months, it's a disappointment. But once you spool back up and everything's ready, and it looks like everything's falling into place nicely, the team's really excited and we're ready to get off the ground."
A detailed countdown timeline is posted here. Here are highlights (in EDT and hours and minutes to launch):

Giusto. Ovviamente NASA TV è la prima fonte per il webcast di tutto cioè che concerne le missioni umane e scientifiche, e in primis ovviamente il programma STS e ISS. Quindi tutta la missione la si può seguire in diretta su NASA TV via Real o WindowsMedia.
In seguito come diceva Octane si potranno trovare filmati anche in alta risoluzione fino ai filmati HDTV 1280i (sul mulo, presi da HDnet che ha l'esclusiva in concessione dalla NASA).

Il countdown non è sempre attivo, durante tutto i tre giorni per cui è attivo ogni tanto ci sono periodi in cui viene sospeso, serve per poter gestire meglio le fasi di prelancio... ti consiglio di dare un occhio qui per capire il funzionamento:

Ah si scusa, in effetti potevo anche leggere meglio... :D
cmq il Crawler Transporter, concepito per il programma Apollo, dovendo trasportare lo stack (circa 2000 t) ed il suo stesso peso (2700 t) è abbastanza potente (:D), anzi il più potente mezzo cingolato al mondo, e sviluppa circa 7000 CV (approssimativamente 5700 kW) solo per il movimento, poi ha altri 150 kW per alimentare la piattaforma di lancio.
Ah, consuma circa 350 litri di gasolio per km percorso! :p

si, dal momento in cui lo shuttle supera la torre della piattaforma di lancio.
Il controllo missione è sempre stato a Houston, per motivi di sicurezza.
wow!!
in vacanza?
ma non ho capito... è il JSC che coordina ?
Più o meno, era una sorta di borsa di studio, ho passato un mese a Houston e sono andato due volte a visitare la Nasa.
Una sfiga cosmica, proprio la mattina della prima visita c'è stata la sparatoria al JSC, così la seconda volta abbiamo potuto fare solo il giro turistico. In realtà la prima mattina abbiamo fatto il giro dei... raccomandati :p e abbiamo incontrato Nespoli, che andrà su con lo shuttle con una delle missioni di quest'autunno, se non ricordo male, l'edificio con i modelli in scala reale di shuttle e stazione spaziale dove gli astronauti fanno l'addestramento, le sale di controllo dello shuttle e della stazione spaziale e alcune altre cose.
Tra l'altro mi ha impressionato la Soyuz, ha le dimensioni di un ascensore!!!
Comunque dovrebbe funzionare così: Cape Canaveral gestisce il lancio, appena lo shuttle è lanciato la palla passa a Houston.
Davvero?!? e non mi hai detto niente? :mad: :O
Eh, eri la giusto giusto quando c'è stata la sparatoria eh... ebbravo! :P
Sì, come dicevo prima, proprio un'ora e mezza dopo la nostra prima visita :D
Ma non sono io che porto sfiga, come sostengono dove lavoro :O
Vuoi una mia foto seduto al Flight Control della sala controllo Apollo? :cool:

2304 GMT (7:04 p.m. EDT)
Weather at the abort landing site in Istres in France was just announced "go." That would give NASA the one required Transatlantic Abort Landing site for launch this evening.

Tra l'altro ho visto anche come arrivano le piastrelle dello shuttle dopo il rientro, ce ne sono alcune con dei buchi da matti. C'era il bancone dove imparavano a fare le riparazioni con la resina ed usano le piastrelle "usate" nei vari voli.
C'è anche la copia -modificata per l'uso terrestre- del canadarm: per addestrarsi hanno una sorta di palloni gonfiabili a forma dei moduli dell'ISS e li usano per simulare il carico e lo scarico della stiva.
2324 GMT (7:24 p.m. EDT)
The final readiness poll by the NASA test director Steve Payne confirms there are no technical issues being addressed. The Range also reports "go" on the local weather. And Mission Control says that the TAL weather in France is acceptable.
2324 GMT (7:24 p.m. EDT)
NASA launch director Mike Leinbach has conducted his poll and given approval to resume the countdown for liftoff at 7:38 p.m. this evening!

Grazie! Se ti installi Picasa basta e clicchi sulle foto che vuoi uploadare, dopodichè ci pensa lui a riduerle e a caricarle via ftp sul tuo profilo di picasaweb, creando un nuovo album.
L'album lo puoi fare totalmente pubblico, con inserimento nella ricerca della community di picasa, o pubblico senza aggiunta alla ricerca, oppure privato con invito.

T-minus 3 minutes. Orbiter steering check is now complete; the main engine nozzles are in their start positions.
2335:34 GMT (7:35:34 p.m. EDT)
T-minus 2 minutes, 30 seconds. The external tank liquid oxygen vent valve has been closed and pressurization of the LOX tank has started.
Atlantis' power-producing fuel cells are transfering to internal reactants. The units will begin providing all electricity for the mission beginning at T-50 seconds.
And pilot Lee Archambault has been asked to clear the caution and warning memory system aboard Atlantis. He will verify no unexpected errors in the system.
In the next few seconds, the gaseous oxygen vent hood will be removed from atop the external tank. Verification that the swing arm is fully retracted will be made by the ground launch sequencer at the T-minus 37 second mark.

Atlantis, prime preoccupazioni
Tecnici hanno individuato area esposta in protezione termica
(ANSA) - NEW YORK, 9 giu - Prima preoccupazione per lo Shuttle Atlantis: i tecnici hanno individuato un'area esposta nel sistema di protezione termica. Secondo la Nasa, la zona dove si e' registrato il problema non e' di quelle che si surriscaldano particolarmente al rientro. L'equipaggio si e' svegliato sulle note della canzone 'Big Boy Toy' di Aaron Tippin. L'Atlantis sta inseguendo la stazione spaziale internazionale, dove e' attesa domani pomeriggio.
si ma in realtà è una copertura termica (TPS) che sporge all'esterno fuori da uno degli ugelli di sinistra del'OMS (Orbital Manuevering System), ma non dovrebbe essere preoccupante per il rientro.

TPS inspections for Atlantis - Port OMS Pod blanket issue
By Chris Bergin, 6/9/2007 1:28:11 AM
A four inch piece of Thermal Protection System (TPS) blanket is protruding out of the port OMS (Orbital Maneuvering System) Pod - and is currently being evaluated by managers on the ground.
The damage to the blanket was reported by the crew at 3:45am GMT at the latter stages of Flight Day 1. Flight Day 2 involves a full day of inspections - as scheduled - which will include a closer look at the OMS Pod blanket, which wasn't hit by a close passing tyvek cover, managers claimed on Saturday.
After what was a clean ascent from initial information, Atlantis will undergo an extensive scan of her TPS during Flight Day 2. Further photography will be taken of her belly just prior to arrival at the International Space Station (ISS) on Sunday.
Two small pieces of foam were observed liberating from the tank on the ET cam during ascent, although they appear to hold no concerns, given their size, time of release, along with apparently missing the orbiter. Managers noted that it is usual to see these small releases at that stage of the ride uphill.
What is gaining notes of interest is the protruding piece of blanket on the OMS Pod, which was spotted by the camera on the end of the RMS (Remote Manipulator System) following its unberthing. Such 'tears' in TPS blanket have been observed before on previous missions.
'Preliminary Area of Interest in TPS inspection: Around a 4 inch blanket reported sticking out at the port OMS pod at the time of the black time 'Christmas tree',' noted NASA information. 'Crew reported that on the port OMS pod they can see a 4 to 5 inch piece of blanket sticking up. They are getting photos.
Plans are already being made to take a closer look during the Flight Day 2 TPS inspections. More information is expected early FD 2.
In all, Atlantis only has two issues on orbit. Four anomalies were noted from the countdown to being on orbit, with the first two - MSBLS 3 (MLS - Microwave Landing System) Failed Range Self Test and MPS (Main Propulsion System) LO2 Left ECO (Engine Cut Off) Sensor 2 Momentary 'Dry' Indication - both understood conditions.
The latter two issues were bot found shortly after Atlantis started on-orbit operations, one being the aforementioned 'Port OMS POD Blanket Sticking up' anomaly, and the other being 'FA3 Card 14 A/D BITE,' which is low-level diagnostic circuitry, used to help discriminate real problems from instrumentation failures.
'FA3 is the #3 Flight Aft MDM, with an MDM basically being I/O controller, relaying commands and data between the GPCs (General Purpose Computers) and actuators, sensors, etc. of various types,' explained a source. 'Card 14 is an I/O card in the MDM. A/D refers to the BITE circuitry on the analog-to-digital converter on that card.'
Latest reports from sources on Saturday speak of a Tyvek cover which was seen to pass by the OMS Pod in question. However, NASA managers believe the cover didn't make contact on first views in hi resolution images - acquired by L2 - of all debris events during ascent.
'Analysis by launch team looking at other camera views show that the tyvek cover did NOT strike the OMS pod,' noted NASA information, following some notes that this was the cause of the damage.
"Tyvek cover released 11.2 seconds after launch. Cover passes near port OMS pod but does not contact it."
Further information will be added as it arrives.

Oh ragazzi, ma qualcuno di voi è mai riuscito ad osservare da terra ( e da dove sennò :D ) un passaggio dello space shuttle ?
Sto smanettando su orbitron e siti come heavens-above e calsky, ma sembra che tutti i passaggi visti da casa mia, pur con una buona magnitudine ( intorno alla 1 ) saranno molto bassi sull'orizzonte :cry:

1930 GMT (3:30 p.m. EDT)
Final approach beginning. The alignment between docking ports on Atlantis and the space station is acceptable and no "fly out" maneuver by the shuttle is necessary.
1934 GMT (3:34 p.m. EDT)
Now 15 feet separating the shuttle from the station. Atlantis' thrusters are programmed to fire in a post-contact maneuver to force the two docking ports together. That procedure is now armed and ready.
1936 GMT (3:36 p.m. EDT)
CONTACT AND CAPTURE! Atlantis has arrived at the space station to install the Starboard 3/Starboard 4 truss segment and unfurl two giant solar wings to increase the amount of power available to the orbiting outpost.
The relative motions of the shuttle and station will be allowed to damp out over the next few minutes by the spring-loaded docking system. Later, the hooks and latches will be closed to firmly join the two craft and Atlantis' Orbiter Docking System docking ring will be retracted to form a tight seal.
The opening of hatches between the station and shuttle is expected in about 90 minutes. That will be followed by a welcoming ceremony and safety briefing. Then the joint crews will get down to business and use the shuttle robot arm to hoist the truss out of Atlantis' payload bay for handoff to the station's arm.
1947 GMT (3:47 p.m. EDT)
The docking ring between the two craft has been retracted into Atlantis' Orbiter Docking System, pulling the station to a tight mating. The hooks and latches are driving shut to firmly connect the two spacecraft.
Pressure and leak checks will be performed by the crews before the hatchway is opened.
2035 GMT (4:35 p.m. EDT)
Hatch opening and the welcome ceremony are coming up shortly. Meanwhile, members of the shuttle crew are preparing to use Atlantis' robot arm to grapple the truss in the payload bay.
------------------------------
Prossima apertura del portelllone di ingresso nel nodo Unity!
2121 GMT (5:06 p.m. EDT)
HATCHES OPEN. The hatchway between the space shuttle Atlantis and space station were opened at 5:04 p.m. EST.
Over the next couple of hours, astronaut Clay Anderson will begin moving his things aboard the station and become an official member of Expedition 15. Station resident Suni Williams will in turn become a shuttle astronaut for the trip back to Earth.
Also upcoming is the unberthing of the S3/S4 truss from Atlantis' payload bay by the shuttle robot arm. The truss will be handed to the station's arm to stay overnight. Installation of truss occurs tomorrow morning.

Ho però qualche curiosità (premetto che sono assolutamente ignorante in materia):

Grazie.

queste domande hanno avuto risposta in discussioni precedenti, forse cercando le trovi, cmq se ti interessa sono riportate anche nell'indice in alto. ;)
Ad ogni modo... brevemente:
- perché sta "a testa in giù"?
Essenzialmente lo shuttle esegue quello che si chiama Roll Program subito dopo aver abbandonato la torre di lancio per tre fondamentali ragioni:
1) ridurre lo stress meccanico sullo stack (orbiter + SRB + ET)
2) migliorare le performance aerodinamiche e risparmiare propellente
3) consentire una migliore comunicazione a bassa frequenza tra lo shuttle e il controllo missione a terra e non ultimo permettere al comandante/pilota di mantenere punti di riferimento con la superficie terrestre
- che fine fanno i "serbatoi" che ha sotto una volta sganciati?
di serbatoio ce n'è uno solo e si chiama ET (External Tank), contiene il propellente per i tre motori a idrogeno liquido montati sull'orbiter (la navetta), nella forma di idrogeno liquido (il combustibile) e ossigeno liquido (il comburente). L'ET viene staccata dall'orbiter su comando dei computer di bordo (GPC, General Purpose Computers) nel momento in è stata raggiunta l'orbita prevista, dopo il MECO (Main Engine Cut Off), lo spegnimento dei motori.
L'ET brucia nell'ora seguente al rientro nell'atmosfera. E' infatti l'unico elemento non riutilizzabile del sistema.
I due razzi laterali generano invece il 78% di spinta al lancio e sono a propellente solido (APCP, Propellente Composito di Ammonio Perclorato, con perclorato d'ammonio che fa da comburente, alluminio da combustibile, ossido di ferro come catalizzatore, più un paio di polimeri epossidici... è il propellente solido con il maggiore impulso specifico sintetizzato al mondo, circa 242 secondi sul livello del mare o 268 nel vuoto assoluto). Si staccano a 2:05 minuti dopo il lancio e vengono successivamente recuperati dopo essere precipitati nell'oceano.
- sono in qualche modo guidati nella caduta?
No, gli SRB dal momento del distaco precipitano per cauta libera nell'oceano, mantenengo costantemente il tracking radio con il controllo missione. Nel momento in cui raggiungono una certa altezza (se non erro intorno ai 200 m) vengono aperti dei paracadute che li rallentano accompagnandoli nello "spash down".
Vengono poi recuperati da 2 rimorchiatori appositamente realizzati, la Liberty Star e la Freedom Star.
Grazie.
Prego.

1350 GMT (9:50 a.m. EDT)
The Atlantis astronauts are gearing up to attach a 36,000-pound solar array truss segment to the international space station today. Once the stowed arrays are in place, astronauts Jim Reilly and Danny Olivas plan to stage a six-and-a-half-hour spacewalk to make critical electrical connections and remove a variety of launch locks and restraints to prepare the new solar blankets for extension Tuesday.
1827 GMT (2:27 p.m. EDT)
The initial stages of the connection process have been accomplished. Four bolts will be driven to physically mate the truss to the station and the robot arm will release its grip.

Mission extended two days; blanket repair ordered
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: June 11, 2007
NASA's Mission Management Team decided today to extend the shuttle Atlantis' mission by two days and to add a fourth spacewalk Sunday. That will give the astronauts enough time to complete their space station assembly tasks and fix a pulled-up insulation blanket on one of the ship's aft rocket pods. Flight controllers plan to make a decision Tuesday on whether to add the blanket repair to the third or fourth spacewalk.
"Based on our analysis today, we have upped our desire to fix this," said John Shannon, chairman of NASA's Mission Management Team. "We were looking at flight history, saying this doesn't look like a big deal. Then you go look at your analysis tools and say hey, I could really damage the top surface of my structure and I sure don't want to do that. So let's go have a good effort to repair it before we come home."
Landing at the Kennedy Space Center now is targeted for around 1:54 p.m. on June 21.
http://www.spaceflightnow.com/shuttle/sts117/070611extend/blanketrepair.jpg
This illustration shows a possible scenario of using the shuttle's robot arm to move a spacewalker in reach of the blanket for repair. Credit: NASA
The protruding insulation was spotted by the shuttle astronauts during a routine post-launch payload bay survey using the shuttle's robot arm. A camera on the arm spotted a triangular 4-inch by 6-inch corner of a two-inch-thick insulation blanket that was sticking up and bent back. Engineers later concluded air rushing over the rocket pod during the shuttle 's climb out of the lower atmosphere worked its way into a corner or seam and peeled the blanket back.
The concern is that hot air during re-entry could damage the underlying graphite epoxy structure of the left-side Orbital Maneuvering System rocket pod. During the 15 minutes or so of peak heating, the temperatures on the OMS pods reach 700 to 1,000 degree Fahrenheit. While engineers do not view this as a life-or-death sort of problem - shuttles have safely returned to Earth with much more serious OMS pod damage - there are enough unknowns to prompt caution.
"We have limitations in our ability to analyze this," Shannon said. "You're going to have a temperature that exceeds that top face coat capability. How long it would take to completely erode is very questionable, no one could give me that answer. So the right answer here, the better part of valor, was to go and put it down and secure it."
At the extreme altitude of peak heating, there is little aerodynamic pressure, Shannon said, and simply folding the corner back down and tucking it in might be sufficient. Engineers are still assessing techniques for securing the blanket if necessary.
Engineers used post-Columbia software to model what might happen if the blanket ripped away during the later stages of the descent, when the airflow is stronger, and concluded it would not hit the shuttle.
As it turns out the material used in the blanket will make the fix relatively straight forward.
"If you take this blanket and you pull it up like the wind is hitting it, it'll stay up like that," Shannon said. "It's got some memory. But when you push it back down, it stays down. That's something we're kind of counting on. We think the astronauts will be able to go out there and just push this right back down. They're working right now different ways to attach it to the blanket that's laying beside it or maybe to attach it to the tile face that's in front of it."
The repair work is expected to take 90 minutes to two hours to complete. An astronaut, his feet anchored to an extension on the end of the shuttle's robot arm, will be maneuvered back to the left-side OMS pod and push the flap down.
It may be possible to attempt the repair during the crew's third spacewalk Friday, but that would require a major push to complete the procedures in time.
By adding a fourth spacewalk, mission managers can preserve their options for dealing with the blanket and any problems that might develop later this week when flight controllers attempt to retract the P6-2B solar array.
The P6 arrays provided the initial power to U.S. modules during the early phases of construction. Now, P6 needs to be retracted, moved out to its permanent location on the left end of the station's main solar power truss and re-extended.
Shuttle astronauts ran into major problems retracting the P6-4B solar blanket last December and the Atlantis astronauts may have similar problems with the P6-2B wing that is still extended. Flight controllers will begin retraction procedures Wednesday and astronauts Steve Swanson and Patrick Forrester will be standing by to assist if necessary.
Additional P6-2B retraction time is built into a third spacewalk Friday. With the decision to fix the pulled-up blanket, NASA managers opted to add a fourth spacewalk to ensure enough EVA time is available to handle the repair and any problems that might crop up during the P6 retraction.
"It was a very easy decision," Shannon said.
He added that engineers have completed their initial assessment of Atlantis' nose cap, wing leading edge panels and heat shield tiles and found no other issues that require any attention.

Space station deploys its new set of solar wings

STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: June 12, 2007
Two new solar array wings attached to the international space station Monday were slowly unfurled today, pulled from their storage boxes by self-assembling masts. Carried out in stages, the 15-foot-wide wings extended like giant window blinds, stretching some 240 feet from tip to tip.
As the first array wing - S4-1A - deployed to its full length shortly before 12:30 p.m., the gold-colored blankets rippled and gently oscillated back and forth as folded slats separated and were pulled taut.
"And Houston, ISS, we see 100 percent deploy on 1A," astronaut Jim Reilly radioed from the Destiny laboratory module.
Forty five minutes later, the other wing of the new array - S4-3A - was deployed, first to 49 percent and then, after a half-hour pause, to 100 percent. Again, there were no problems.
"Houston, ISS, we see a good deploy," Reilly confirmed when the second wing unfurled.

Station teams scramble to resolve computer glitch
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: June 14, 2007
A major computer failure in the Russian segment of the international space station, possibly triggered by the addition of new U.S. solar arrays earlier this week, has shut down critical systems and left the outpost dependent on the shuttle Atlantis for any major changes in orientation. The space station has plenty of supplies on board and the combined 10-member crew is in no immediate danger. But the space station cannot safely operate without the Russian computers and the problem must be resolved before Atlantis departs next week.
Russian engineers will "begin in ernest tomorrow morning to try techniques to recover these computers," said Mike Suffredini, manager of the space station program at the Johnson Space Center in Houston. "I fully expect us to be able to do this. I'm not thinking this is something we will not recover from.
"But in the meantime, being NASA and the fact that we try to do everything we can to protect every option, we are looking at options to extend the time that the shuttle guys stay (docked) with us just in case we'd like an extra day or so. We can't extend it much, but we're certainly looking at that. We're also looking at a number of different options for how we'd conserve (propellant) if we decided we needed more attitude control help from our shuttle friends."
Space station assembly began in November 1998 and it has been continuously manned by rotating U.S. and Russian cosmonauts and astronauts since November 2000. Atlantis ferried a fresh U.S. astronaut to the station - Clay Anderson - to replace Sunita Williams, who was launched to the station last December aboard the shuttle Discovery. Shortly after Atlantis docked, Anderson officially joined Expedition 15 commander Fyodor Yurchikhin and flight engineer Oleg Kotov. Williams, in turn, joined Atlantis' six-member crew.
The Russian segment of the space station utilizes three guidance, navigation and control computers to maintain the lab's orientation and make major orbit adjustments by firing rocket thrusters in the Zvezda command module. Three command-and-control computers also are available to operate a variety of systems like the Russian Elektron oxygen generator and the Vozdukh carbon dioxide scrubber.
For normal operations, the station relies on U.S. control moment gyroscopes, or CMGs, which can make small adjustments in orientation without the need for fuel-consuming rocket firings. Controlling the station's orientation, or attitude, is critical for ensuring its solar arrays can stay lined up on the sun and to prevent sensitive systems from getting too hot or too cold.
The Russian system features "three of those (guidance computers), they're all redundant to each other so any one of the computers can do the job," Suffredini said. "And then we have (three) command-and-control-type computers, called 'lanes,' any one of which can do the command-and-control function. And then we have computers on the U.S. segment that talk to these computers."
When problems occur that might take down the guidance computers, the system is programmed to reboot itself and in the past, that procedure successfully resolved a variety of problems. This time around, it didn't.
On Monday, the Atlantis astronauts attached a new 36,000-pound solar array truss segment featuring two new solar blankets capable of generating some 20 kilowatts of additional useable power. On Tuesday, a computer crash occurred that ultimately left the Russian segment with a single guidance computer and a single command-and-control machine. That, in and of itself, was not crippling.
But Wednesday morning, as the Atlantis astronauts were beginning work to retract a different solar array wing, "we lost both of those computers," Suffredini said. "Currently we're in that configuration. The guidance, navigation and control computers and command-and-control computers in the service module are not functioning. Our Russian colleagues tried a number of techniques to try to recover the computers and were not successful."
Unlike NASA, the Russian space agency does not have its own communications satellites. To troubleshoot the computer problem, Russian engineers had to wait until the station was within line-of-site of Russian ground stations to downlink telemetry, beginning early Thursday.
The combined shuttle-station crews have plenty of oxygen, food and water, along with carbon dioxide removal capability. Even so, "this is a very serious situation," Russian flight controllers told Yurchikhin early today.
"Where does that leave us? The guidance, navigation and control computers allow the system to control the attitude and provide propulsion, if necessary, with Russian thrusters," Suffredini said. "Without those computers, we can't get attitude control from the Russian system. That's not a problem for us, the CMGs (U.S. control moment gyroscopes), in fact, are controlling the attitude and they've done a very fine job. ... If they saturate (get overloaded), we can hand over to the shuttle system and they can take care of the attitude control function."
"That's not an urgent situation but clearly we need to get this resolved before our shuttle friends leave," Suffredini said. "We have plenty of resources and plenty of time to sort this out. We have in the history of the program often had these computers go down, one or two lanes. It's not uncommon to be on one lane of each system and wait for the last one to finally give up and then the whole system reboots itself and starts back up. Of course, what's unique is when the system went to reboot itself it wasn't able to do that."
Engineers are trying to identify changes in the station's configuration or the space environment that might have triggered the crashes, including space radiation and the electrical environment around the station.
"The one that folks are starting to look at and scratching their heads a bit about is we did, of course, add another power source in the form of the S3/S4 (solar array) truss, so we're off looking at is there anything about that power source that may make it slightly different for reasons that aren't clear ... that may have affected the ability of these computers to operate correctly," Suffredini said. "And then, of course, on the Russian segment there are a number of things our Russian colleagues will look at as well to see if they can figure it out."
Suffredini said engineers have not ruled out a software glitch, but no software changes were made over the past few days and all six computers "didn't just all have a hardware failure. It appears to me that something has changed in the environment, either something in the (space) environment or the source of power to these computers is different coming from S3/S4 for reasons we do not understand."
"Our Russian colleagues believe it's the power source," he said. "That's the latest theory they have. They've suggested that perhaps we could stop feeding them power and let them just use their own internal power to bring up their computers and see if that solves that particular problem. They cannot run (completely) on their own power because of all the systems to handle the entire crew. We have to feed them a certain amount of power to keep everything running that we need to run. So eventually we have to work through that.
"Another option we're working through is just stop feeding them power from the S3 truss, which is maybe the first thing we'll try. We're still sorting through our plan."
In the meantime, shuttle planners are assessing possible power conservation steps that would permit Atlantis to remain docked an extra day if necessary. As of late Wednesday, the shuttle had enough hydrogen and oxygen for its electricity producing fuel cells for an additional 18 hours of docked activity. By deferring the planned transfer of 40 pounds of oxygen to the station, the shuttle crew will likely be able to get an extra docked day if necessary.
"We have to have propulsive attitude control even with CMGs," Suffredini said. "The CMGs do a great job but occasionally they get saturated and when they get saturated, we need propulsive attitude control in order to recover. The other need for propulsion is to make sure we can do debris avoidance maneuvers, to adjust our orbit for dockings, there's a number of reasons why we need propulsive attitude control. That's a requirement of the ISS. We have to have that capability."
In a worst-case scenario, he said, the astronauts would have to abandon the station and come back to Earth. The Expedition 15 crew would come home in a Russian Soyuz capsule while the shuttle crew would depart aboard Atlantis.
But that's strictly worst case, Suffredini said, adding he was confident the Russians would resolve the problem in short order.

Russian computer system partially revived
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: June 14, 2007
Engineers have re-established communications with at least one part of the space station's Russian guidance and command-and-control computers. They are receiving a full stream of telemetry and have been able to restore power to critical systems.
The navigation system and command computers feature three redundant data paths and only one path, or lane, has been re-established. Troubleshooting continues, but engineers have restored station power to systems in the Zvezda and Zarya modules. The crew's Soyuz lifeboat, which was put on internal power late Wednesday as a precaution, also was switched back to station power.
Details were sketchy, but a NASA official said commanding to the one restored computer lane had been restored and the Russians could, if necessary, use it to adjust the space station's orientation by firing Russian rocket thrusters.
Attitude control is critical to keeping the lab's solar arrays properly oriented and to preventing sensitive systems from getting too hot or too cold. The guidance computer system must be operational before the shuttle Atlantis departs next week.
During the station's next pass over Russian ground stations later this morning, commands will be uplinked in a bid to restart lanes two and three. It is not yet clear whether the Russians have tracked down the root cause of the problem or whether it could happen again.
Russian engineers speculated Wednesday that the failures may have been related to the installation of a new U .S. solar array Monday. Early today, they isolated the Russian segment from U.S. power while they worked to restart the computers. U.S. power later was restored with no apparent problem.

Interoperabilità tra sistemi...:rolleyes:
Scherzi a parte una bella gatta da pelare per l'ISS:
Mi riassumi l'articolo?:)
In poche parole alcune dei computer che governano la distribuzione dell'energia nel segmento russo della ISS e soprattutto il controllo dell'assetto della stazione nel lato russo dal modulo di comando "Zvezda" hanno presentato malfuzionamenti e riavviandosi automaticamente, forse a causa dell'installazione dell'ultimo array di pannelli solari del segmeno S3/S4.
Di conseguenza finchè il problema non sarà sistemato il modulo di comando non sarà in grado di controllare l'assetto della stazione (attitude control), rendendo quindi indispensabile l'uso dei giroscopi e lo Shuttle per garantire il mantenimento dell'orientamento della ISS. Durante le missioni di costruzione della ISS il controllo d'assetto e navigazione viene spesso interscambiato tra il modulo di comando Zvezda (quindi l'ISS) e lo Shuttle, a causa della necessità di sezionare elettricamente parti della stazione, in particolare durante l'installazione dei pannelli solari, e per sfruttare il propellente di navigazione dello Shuttle risparmiando quello dello Zvezda.
Dall'articolo riporto le parti più interessanti:
The Russian segment of the space station utilizes three guidance, navigation and control computers to maintain the lab's orientation and make major orbit adjustments by firing rocket thrusters in the Zvezda command module. Three command-and-control computers also are available to operate a variety of systems like the Russian Elektron oxygen generator and the Vozdukh carbon dioxide scrubber.
For normal operations, the station relies on U.S. control moment gyroscopes, or CMGs, which can make small adjustments in orientation without the need for fuel-consuming rocket firings. Controlling the station's orientation, or attitude, is critical for ensuring its solar arrays can stay lined up on the sun and to prevent sensitive systems from getting too hot or too cold.
The Russian system features "three of those (guidance computers), they're all redundant to each other so any one of the computers can do the job," Suffredini said. "And then we have (three) command-and-control-type computers, called 'lanes,' any one of which can do the command-and-control function. And then we have computers on the U.S. segment that talk to these computers."

Computers shut down again for more troubleshooting
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: June 15, 2007
Russian computers aboard the international space station failed to boot up properly early today even though they were cut off from U.S. solar array power. Engineers had speculated that some subtle change in the station's shared power grid, caused by the installation this week of a new solar array, might have triggered the Russian computer crashes that have crippled the space station. But analysis of the electricity flowing from the new array into the Russian segment of the lab complex did not reveal any obvious "smoking gun" and when the circuit was unplugged, the computers behaved much as they did Thursday.
The station's main command-and-control computer system is made up of three redundant machines that can operate in stand-alone mode or as synchronized, fully redundant "lanes." The station's guidance and navigation system is known as the terminal computer, also made up of three redundant lanes. The computers normally draw power from the station's shared electrical grid, which includes electricity from U.S. solar arrays. The new array channel that was routed to the Russian segment earlier this week, roughly when the computer problems began, is known as power channel 3A.
Russian engineers "performed some more troubleshooting over the last two ground sites and basically, kind of a repeat of some troubleshooting they did yesterday," said space station flight director Holly Ridings. "If you remember yesterday, they'd been successful in bringing up the central computer and talking to it and getting a command down to the FGB (Zarya module) to get some power over from the U.S. segment to the Russian segment. Unfortunately ... that computer, the central computer, went off line again.
"And so today's troubleshooting was kind of a repeat of what they did yesterday, trying to turn on the central computer and then the terminal computer. And unfortunately, they did get power to both of those computers and get good feedback that they were receiving power, briefly had some what they call 'availability,' kind of like a heartbeat, on one of the lanes. There are three of them, of the central computer and the computer below it, the terminal computer, but were unable to communicate with it properly.
"So on the next ground site after they'd left the power to those computers on for about an hour and a half, they decided they would turn the power back off again and turn what we call an SNT (a Russian acronym pronounced ess-en-tay), which is how we send power from the U.S. power system to the Russian segment, back on. So we ended up in the configuration that we started out the day in, which was, unfortunately not having a central computer or a terminal computer. They're going to let the crew get some sleep ... and put together a forward troubleshooting plan."
The computer system has been acting up ever since the Atlantis astronauts attached a new set of solar arrays to the right side of the station's main power truss Monday. The terminal computer lanes initially crashed. Then, during a programmed reboot of both the terminal and central computer lanes, the entire system hung up.
The navigation system computers are required to fire Russian maneuvering jets to make major changes in the station's orientation. Minor adjustments are made with U.S. control moment gyroscopes, but that cannot make major changes and the system periodically has to be reset using rocket control. The station cannot safely operate without full orientation control to ensure its solar arrays stay face-on to the sun and to prevent sensitive systems from getting too hot or too cold.
The problem is not serious as long as the shuttle Atlantis remains docked because the orbiter's thrusters can be used, when needed, to make adjustments that are beyond the ability of the gyros or when the gyro system needs to be reset. But the shuttle will undock and return to Earth next week and the Russians have been working around the clock to get the computer glitches resolved before the orbiter departs.
Engineers theorized that the new S4 solar array, or components in the circuitry delivering that power to the Russian segment of the station, triggered some subtle change in the lab's electrical grid. The central and terminal computers, built in Germany by Daimler-Benz in Germany ( :read: , ndGio... :D ), are known to be sensitive to "noisy" power.
Late Thursday, outgoing station flier Sunita Williams, her replacement Clay Anderson and flight engineer Oleg Kotov used a signal analyzer to characterize the power flowing from the U.S. to the Russian segment. After that data was shared with the ground, the system was physically disconnected to make sure no ground path could be causing problems even with power shut down.
"One of the theories about why this is going on with the computers is that there's some interference from the new pieces of the power system that we put in with the S4 truss and possibly some electromagnetic interference or some other issue with the power that we're sending them across," Ridings said.
"So we asked the crew to go in and do some testing with the scope meter on the actual power cables that come from the new truss and power channel 3-alpha to those SNTs, the boxes that send the U.S. power over to the Russian segment. So they put the scope meter on those cables and looked at the waves ... so all our engineers could go off and assess.
"The engineers looked at that data, they did not find anything that was grossly off nominal, nothing huge jumped out at them immediately," Ridings said. "It would have been nice to find a smoking gun, but that's usually not how these things work."

Spazio: Iss, guasto risolto
I cosmonauti russi fanno gli elettricisti a bordo
(ANSA) - WASHINGTON, 16 GIU - I cosmonauti russi a bordo della Stazione spaziale internazionale (Iss) hanno risolto il problema ai computer di bordo. Per la prima volta si e' addirittura ipotizzato di ordinare di 'abbandonare la nave'. Ieri sera il guasto era stato pressoche' riparato, grazie all'intuizione di uno dei cosmonauti russi a bordo, che ha collegato direttamente alcuni dei computer alla fonte di energia, senza passare attraverso gli interruttori, risultati guasti.

I pannelli dovrebbero fornire tensione continua o viene "trasformata" in alternata per limitare l'attenuazione?

*credo* che lavorino in continua.
Avranno sicuramente degli stabilizzatori switching per ottenere le varie tensioni, ma dubito che girino in alternata sulla stazione... maledizione, quell'ingegnere della NASA che avevo conosciuto mi aveva parlato del sistema elettrico dell'ISS ma non mi ricordo più cos'aveva detto :muro: E' che mi aveva raccontato tante cose :stordita: Pensa un po' che lui era uno di quelli che aveva lavorato sul pezzo che ha ceduto sull'Apollo 13 e si è portato a casa uno dei modelli e me l'ha fatto vedere, ho tenuto in mano il mescolatore che ha fatto corto sull'Apollo 13 :D
Comunque, lo so che dopo son buoni tutti, ma prima di leggere la notizia della riparazione avevo proprio pensato che fosse un problema di alimentazione, perchè non era possibile che tutti e tre i computer andassero giù assieme :read:

Two more space station computers revived
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: June 16, 2007
Hoping for the best, space station commander Fyodor Yurchikhin and flight engineer Oleg Kotov hot wired two computers aboard the international space station today that engineers had feared were victims of fatal power supply failures. To everyone's delight, the machines promptly booted up and appeared to be running normally, two more successes in an improbable recovery from crippling computer crashes last week.
Two of the three computers making up the Russian segment's guidance, navigation and control computers, along with two of three central control computers, were successfully revived Friday when Yurchikhin and Kotov used jumper cables to bypass suspect surge protectors in secondary power supply circuits.
The redundant so-called soft switches were designed to shut off power to their respective computers in the event of surges or spikes in the incoming electricity. Engineers now believe the installation of a new solar power truss last Monday triggered a subtle change in the station's power grid that somehow caused the secondary power supply switches to respond, preventing their computers from booting up.
Russian engineers believed four of the six primary computers were healthy and victims of the overly sensitive switches. When the switches were bypassed Friday, the four computers, two in each system, booted up normally. After a thorough checkout, one machine in each chain was put back in control of critical station functions.
Russian engineers believed the other two computers were victims of power supply hardware failures and no attempt was made to start them on Friday. But today, Yurchikhin and Kotov installed jumper cables on the off chance the computers were, in fact, healthy and both started up normally.
"Overnight, our Russian colleagues conferred with us and confirmed that, in fact, all six computers are working," said Mike Suffredini, space station program manager at the Johnson Space Center in Houston. "In fact, with the modification they did on the four I told you about last night, they did that modification on those last two, they brought all six computers up and confirmed they were all operating nominally. Then they went back down to a four-computer set again and continued to check out the computers.
"Currently, they have all six computers up while we do some additional troubleshooting to understand the environment and how it might affect the computers."
In the meantime, the Russians have decided to leave one computer in each system on standby to serve as an operational backup should any other problems crop up.
The bottom line, Suffredini said, is that "it appears to everyone the command-and-control-type computers are functioning just fine. In addition to that, we're doing our planning to test the attitude control system. Once we have confirmed the attitude control system can work, that will confirm not only that the guidance, navigation and control set of computers is working but also that the guidance, navigation and control computers can talk to the command-and-control computers. ... So when that test is complete, we will consider that the computers are up and healthy. At that point, we will confer with our shuttle colleagues on a departure date."
Atlantis astronauts Pat Forrester and Steve Swanson plan to stage a six-and-a-half-hour spacewalk Sunday to finish the activation of a powerful rotary joint designed to slowly turn the newly installed S4 solar arrays to keep them roughly face-on to the sun. A variety of other station assembly get-ahead tasks are planned as well.
If all goes well, the astronauts will seal hatches between the station and the shuttle on Monday and undock Tuesday for a return to Earth next Thursday.
"So things are looking up very well," Suffredini said. "If all goes according to plan and the checkout goes well, we will transfer as much oxygen as our shuttle colleagues can afford to give us and then we will ... close the hatch Monday evening and have the shuttle depart on Tuesday."
Engineers still don't know what changed in the space station's electrical system that might have affected the operation of the secondary power supply surge protectors. Suffredini said attention now is focusing on the electrically charged plasma environment the station flies through and how that electrical environment changes as the lab complex grows.
"We've had a lot of discussions with our Russian colleagues, who seem to concur with our assessment that this is probably due to this potential, the plasma environment we fly through, that as the station gets bigger this potential will continue to grow," Suffredini said. "We've been collecting a lot of data, we have instruments that measure this potential. The Russians are very interested in that data. They have noted some changes in their systems as we have grown. ... I think we're going to find there's some sensitivity to the noise that is created as we change the space station."

L'alimentazione sulla ISS è solo continua, a quanto ne so.
1629 GMT (12:29 p.m. EDT)
The shuttle is quickly departing the immediate vicinity of the space station following separation burn No. 2 at 12:28 p.m. The ship should be about 45 miles behind the outpost by later tonight.
The Atlantis crew will perform another series of heat shield inspections this afternoon, then pack up the cabin and test flight controls on Wednesday. The deorbit burn to begin reentry is scheduled for 12:52 p.m. EDT Thursday, with a mid-day touchdown on Kennedy Space Center's three-mile concrete runway at 1:54 p.m. EDT to conclude STS-117.
A backup landing opportunity at KSC is available an orbit later, with a deorbit burn at 2:28 p.m. and touchdown at 3:29 p.m. EDT. Weather could be a problem for both opportunities of the day.
The backup landing sites at Edwards Air Force Base, Calif., and White Sands Space Harbor, N.M., will not be considered on Thursday, NASA says.
The Friday landing times in Florida are 2:15 and 3:50 p.m. EDT. If weather forces the shuttle to Edwards, the landing opportunities for the Mojave Desert military base would be 5:20 and 6:55 p.m. EDT.

Ohè, sicuro!
C'è comunque da dire che americani e russi hanno due filosofie molto diverse nella tecnologia. I russi tendono a fare dei veri e propri "carri armati", gli americani sotto certi punti di vista sono molto più... cowboys, non so se mi spiego :p
Credo, per esempio, che uno scazzone come quello di sbagliare le unità di misura tra due gruppi e perdere due sonde i russi non l'avrebbero mai fatto.

:rotfl:
Credo, per esempio, che uno scazzone come quello di sbagliare le unità di misura tra due gruppi e perdere due sonde i russi non l'avrebbero mai fatto.
avrei voluto vedere le loro espressioni quando hanno realizzato quale e' stata la causa :doh:
Guardate che la cosa è molto più semplice di come la mettiate... ci sono due segmenti della ISS, uno americano gestito dalla NASA e uno russo gestito da RKA (ex RosaviaKosmos). Semplicemente ciascuno gestisce il suo, interoperando con l'altro. Infatti i russi controllano principalmente assetto e navigazione (i russi utilizzano il modulo Zarya e il Progress con propellente per il controllo principale, gli americani dei giroscopi per i piccoli aggiustamenti) e alimentano i propri nodi e moduli (modulo di comando Zarya, modulo di servizio Zvezda, Pirs Docking, modulo di ricerca MLM e il DCM, Docking Cargo Module, oltre alle navette Progress e Soyuz), mentre gli americani alimentano con i pannelli solari principali (P3/P4, P5/P6, S3/S4 ed S5/S6) i propri moduli (laboratorio Destiny, Nodo 1 Unityt, Quest Airlock) e quello Europeo (Columbus) e giapponese (Kibo).
A parte la gestione condivisa tra i firmatari del contratto (NASA, RKA, ESA, JAXA e CSA) ci sono gli accordi disgiunti come quello tra Italia e USA (l'Italia opera all'interno dell'ESA ed indipententemente con la NASA ottenendo maggior accesso all'ISS tramite la costruzione dei moduli riutilizzabili MPLM e dei moduli fissi Node 2 "Harmony" e Node 3.
Sul fatto del problema all'alimentazione alla fine non erano i computer, ma uno stadio di alimentazione, e la causa è ancora da accertare ma di certo nel sistema integrato di alimentazione dell'ISS l'installazione dell'array di pannelli solari S3/S4 non è stato indolore, e potrebbe essere una concausa. Cmq non è che l'hanno scoperto gli americani, se ne sono accorti tutti nel momento in cui si rebootavano, e sicuramente i russi per primi, dato che li gestiscono loro.
Per quello che si vede su NASA TV invece, si può osservare come sebbene il centro di comando sia Houston, NASA ed RKA hanno il controllo delle rispettive sezioni e cooperano al controllo missione dell'ISS, per questo spesso si sentono le comunicazioni russe da Mosca all'ISS e viceversa... semplicemente quando NASA TV passa ai canali russi utilzza un traduttore per permettere agli ascoltatori di capire che di dicono, non è certo il traduttore per i tecnici al controllo missione... ;)
Concordo poi con gp sul discorso del diverso approccio filosofico... in questo è risaputo c'è una notevole differenza storicamente tra russi ed americani, i primi più diffidenti verso l'uomo si sono sempre più affidati alle macchine ed all'automazione (al contrario di quello che magari la grande maggioranza della gente pensa), gli americani l'opposto... vedi ad esempio la capacità da subito di controllo automatico del volo dello shuttle russo Buran (il cui primo e purtroppo unico volo è stato totalmente automatico senza equipaggio) o il docking automatico fin dai tempi della Mir.

Quando sono stato nella sala di controllo mi hanno spiegato che hanno i timer sopra i monitor e, tra i vari conti alla rovescia, ci sono anche tutte le conferenze stampa dei russi, proprio per seguirle (con l'interprete) ed essere aggiornati.

Atlantis departs the space station after successful visit

With pilot Lee Archambault at the controls, Atlantis undocked from the space station Tuesday morning. A couple of hours later, dramatic video looking back past the tail of the shuttle showed the station small in the distance, its face-on solar arrays looking like the wings of a "Star Wars" TIE fighter.
Ragazzi, a che ora il rientro??
facendo un match tra il master flight plan e quello aggiornato dovrebbero iniziare il "deorbit" verso le 18 e atterrare pochi minuti dopo le 19 (ora italiana)
Sempre che non decidano un atterraggio su un sito alternativo, il che porterebbe lo Shuttle a fare un'altra orbita..

WAVEOFF. Atlantis will remain in space for at least another orbit today. Rainshowers developing near the Kennedy Space Center landing strip and low cloud ceilings have forced entry flight director Norm Knight to scrub the first of the day's two landing opportunities.
If the weather situation improves, Atlantis could return to Earth later this afternoon, beginning with a deorbit burn at 2:25 p.m. and touchdown at 3:30 p.m. on Kennedy Space Center's three-mile-long runway.
Should the weather remain "no go" for backup landing opportunity, Atlantis would stay in orbit for an additional day. There are landing options available at KSC and the alternate site at Edwards Air Force Base, Calif., on Friday.

As a rainshower sweeps west-to-east toward the Shuttle Landing Facility, Atlantis has crossed the equator to begin orbit 202. There is not much optimism that the Florida weather picture will improve for a 3:30 p.m. landing of the shuttle. But Mission Control will continue to watch the conditions to gauge any signs of hope before throwing in the towel for today.
1733 GMT (1:33 p.m. EDT)
ANOTHER DAY IN SPACE. Ugly weather at the Kennedy Space Center has given the seven astronauts of space shuttle Atlantis a bonus day in orbit. Entry flight director Norm Knight in Mission Control just made the decision to wave off the second of the two landing opportunities to bring the shuttle back to the Florida spaceport today.
The crew of commander Rick Sturckow, pilot Lee Archambault, mission specialists Pat Forrester, Steve Swanson, Danny Olivas, Jim Reilly and Suni Williams will re-open the payload bay doors, climb out of their entry spacesuits, get something to eat and enjoy the view out the window for the rest of the day.
Friday's first landing option would see Atlantis touch down around 2:14 p.m. EDT at Kennedy Space Center. But the weather is not expected to be much better. A detour to the backup landing site at California's Edwards Air Force Base is a possibility.
Atlantis has enough consumables to remain in space through Sunday, but NASA wants the shuttle safely on the ground by Saturday. A Kennedy Space Center homecoming is preferred since it puts Atlantis on the fast-track to be readied for its next mission in December, which will launch the European Columbus science laboratory module to the space station. A landing at Edwards would cost about $1 million and at least a week to ferry the shuttle back to Florida atop a modified 747 carrier jet.

The latest data from Mission Control says the deorbit burn ignition time will be 1:12:24 p.m. EDT. The two OMS engines on the tail of Atlantis will fire for two minutes and 32 seconds to drop the shuttle out of the orbit for the fiery glide through the atmosphere and landing on Kennedy Space Center's Runway 15 at 2:18 p.m. EDT.
But getting the OK to do the deorbit burn depends entirely on the weather. There's showers and extensive cloud cover at the Cape today.
:)
1604 GMT (12:04 p.m. EDT)
WAVEOFF. The first landing opportunity of the day for Kennedy Space Center has been scrubbed due to the rainshowers around the Cape. Atlantis will circle the globe one more time while Mission Control watches to see if the weather improves in Florida. If the situation remains "no go" at the shuttle homeport for a deorbit burn at 2:50 p.m. and landing at 3:55 p.m. EDT, then NASA will have the ability to scrap the Florida plans and instead go to Edwards on that same orbit.
The upcoming Edwards Air Force Base opportunity would begin with a deorbit burn at 2:43 p.m. and touchdown on Runway 22 at 3:49 p.m. EDT. Current weather at the California base is "go."

FRIDAY, JUNE 22, 2007
1710 GMT (1:10 p.m. EDT)
Astronaut Scott Altman, commander of next year's Hubble servicing mission, has taken to the skies over Edwards Air Force Base aboard a Shuttle Training Aircraft to fly weather reconnaissance. He will relay his observations on the winds and weather conditions to Mission Control. Skies are clear and winds remain within limits for a shuttle landing at the Mojave Desert right now.
Meanwhile, NASA continues to track the clouds and rain at Kennedy Space Center in Florida. Showers are south of the landing strip and slowly drifting further away from the runway. However, the rain is still within the restricted 30 mile circle around the Shuttle Landing Facility. Chief astronaut Steve Lindsey is flying a similar Shuttle Training Aircraft around KSC for weather reporting to flight controllers.
The key times to keep in mind -- the deorbit burn to brake from space for a landing at Edwards would begin at 2:43 p.m. EDT. The Kennedy opportunity on the same orbit begins with a deorbit burn at 2:50 p.m.
This upcoming orbit is the first landing opportunity of the day for Edwards and the final one for Kennedy. A decision on which site NASA will use today is expected within the next hour or so.

Ma che succede se accendono qualche minuto prima o dopo i motori? Si ritrovano su una rotta sballata all'altro capo del mondo?:D
Ma che succede se accendono qualche minuto prima o dopo i motori? Si ritrovano su una rotta sballata all'altro capo del mondo?:D
Se per motori intendi al sistema RCS ed OMS, beh... il loro utilizzo nella fase di deobriting è limitato al controllo dell'assetto e alla corretta riduzione della velocità per l'inserimento nell'atmosfera terrestre... quindi se ne viene fatto un uso diciamo "sbagliato" non è che ti ritroveresti lo shuttle chissà dove, semplicemente non te lo ritroveresti proprio più. ;)
Ma questo è un rischio abbastanza remoto dato che quasi tutte le procedure di rientro sono gestite in modo automatico dai computer di bordo.
1750 GMT (1:50 p.m. EDT)
CALIFORNIA BOUND. Uncooperative weather at the space shuttle homeport in Florida yesterday and again today has left entry flight director Norm Knight no choice but divert Atlantis' landing to the backup site at Edwards Air Force Base in California, where conditions are favorable for the craft's return to Earth this afternoon.
Touchdown on the concrete Runway 22 is expected at 3:49 p.m. EDT to conclude the two-week flight of STS-117.
1819 GMT (2:19 p.m. EDT)
GO FOR THE DEORBIT BURN! Mission Control just gave the Atlantis crew the formal "go" to perform the deorbit burn starting at 2:43:47 p.m. EDT to commit the shuttle for the trip back to Earth.
The upcoming 2-minute, 33-second retrograde burn using the twin OMS engines will slow the shuttle's velocity by nearly 300 feet per second, just enough to slip the craft out of orbit and begin the plunge into the atmosphere.
Atlantis is headed toward a landing at 3:49 p.m. EDT on Runway 22 at Edwards Air Force Base to close out the 13-day, 20-hour mission.

1844 GMT (2:44 p.m. EDT)
DEORBIT BURN IGNITION. Flying upside down and backwards above the central Indian Ocean, Atlantis has begun the deorbit burn. The firing of the twin Orbital Maneuvering System engines on the tail of the shuttle will last two minutes and 33 seconds, slowing the craft to start the trek toward reentry. The retro-burn will send Atlantis to Edwards Air Force Base in California for a touchdown at 3:49 p.m. EDT.
1846 GMT (2:46 p.m. EDT)
DEORBIT BURN COMPLETE. Atlantis has successfully completed the deorbit burn, committing the shuttle for its journey back to Earth. Landing is scheduled for 3:49 p.m. EDT in the high desert of California.
1859 GMT (2:59 p.m. EDT)
Touchdown is 50 minutes away. This will be the 51st space shuttle landing at Edwards Air Force Base, California. The most recent landing there was STS-114, the first post-Columbia mission, back in August 2005. The three subsequent missions last year landed at Kennedy Space Center.
1918 GMT (3:18 p.m. EDT)
ENTRY INTERFACE. Atlantis' thermal protection system is feeling heat beginning to build as the orbiter enters the top fringes of the atmosphere -- a period known as entry interface.
The shuttle is flying at Mach 25 with its nose elevated 40 degrees, wings level, at an altitude of 400,000 feet over the southern Pacific Ocean and descending at a rate of over 600 feet per second.
Touchdown is set for 3:49 p.m. EDT at Edwards Air Force Base.
1923 GMT (3:23 p.m. EDT)
Atlantis is beginning the first of four banks to scrub off speed as it plunges into the atmosphere. These turns basically remove the energy Atlantis built up during launch. This first bank is to the left.
1924 GMT (3:24 p.m. EDT)
Time to touchdown now 25 minutes. Altitude is 250,000 feet. Speed is 16,500 mph.
1930 GMT (3:30 p.m. EDT)
The shuttle is experiencing maximum heating as it descends through an altitude of 43 miles at a speed of Mach 21.
1932 GMT (3:32 p.m. EDT)
The shuttle's aerosurfaces are becoming activate and the roll and pitch reaction control system thrusters are being deactivated.
1933 GMT (3:33 p.m. EDT)
Atlantis is 215,000 feet up, traveling at 13,000 mph.
1934 GMT (3:34 p.m. EDT)
Atlantis' speed is now 11,000 mph and 38 miles in altitude.
1936 GMT (3:36 p.m. EDT)
Atlantis has passed the region of maximum heating.
1937 GMT (3:37 p.m. EDT)
The shuttle is 165,000 feet up, traveling at 10 feet per second.
1938 GMT (3:38 p.m. EDT)
Tracking stations at the landing site have locked on to Atlantis.
1940 GMT (3:40 p.m. EDT)
Global Positioning System data is being incorporated into the primary and backup flight computers.
1939 GMT (3:39 p.m. EDT)
The TACAN navigation units aboard Atlantis are now receiving data from beacons located at the landing site.
1939 GMT (3:39 p.m. EDT)
Atlantis remains on the proper track for landing in less than 11 minutes. Mission Control computes the shuttle will land 2,600 feet down the runway at 195 knots.
1940 GMT (3:40 p.m. EDT)
Altitude is 135,000 feet, traveling at 4,000 miles, 220 miles from the runway.
1942 GMT (3:42 p.m. EDT)
Tally ho on Atlantis. Powerful tracking cameras at the landing site have spotted the descending shuttle.
1943 GMT (3:43 p.m. EDT)
Six minutes to landing. Atlantis is flying over Southern California.
1945 GMT (3:45 p.m. EDT)
Atlantis is descending through 60,000 feet.
1946 GMT (3:46 p.m. EDT)
The shuttle is in the Heading Alignment Cylinder, an imaginary circle to align with Runway 22. The crew is piloting Atlantis through a 260-degree right-overhead turn.
1947 GMT (3:47 p.m. EDT)
Atlantis is on course at the 180-degree mark of the HAC.
1948 GMT (3:48 p.m. EDT)
Atlantis is on final approach. The shuttle descending at a rate seven times steeper than that of a commercial airliner.
1949 GMT (3:49 p.m. EDT)
Landing gear down and locked. Standing by for touchdown on Runway 22.
1949 GMT (3:49 p.m. EDT)
TOUCHDOWN! Main gear touchdown. Drag chute deployed. Nose gear touchdown.
1950 GMT (3:50 p.m. EDT)
Atlantis has returned to Earth after 14 days in space, concluding a success mission that brought more power to the space station by delivering and activating the Starboard 3/Starboard 4 truss and unfurling its two giant solar wings. The crew also completed retraction of the Port 6 power truss arrays for that structure's relocation later this year as the station's expansion proceeds toward the arrival of European and Japanese science labs.
1950 GMT (3:50 p.m. EDT)
WHEEL STOP. The shuttle and crew are back safe and sound!
E questo conclude la telecronaca del ritorno a terra dell'Atlantis a conclusione di una lunga missione di 15 giorni per un passo in più verso il completamento della ISS con l'aggiunta del segmento S3/S4 con un nuovo gruppo pannelli solari per alimentare i labotatori della stazione.
Bentornato a casa Atlantis!
:yeah:
Per quando vedremo l'equipaggio?

Ecco uno shot mentre manovrava in orbita
Anche queste domande sono state risposte in precedenza... cmq se per video del rientro in atmosfera intendi lo Shuttle che entra a contatto con l'atmosfera e passa tutta la fase di "maximum heating" ovviamente non esistono video se non quelli registrati a bordo con telecamere a mano nel ponte di comando (fligh deck) per permettere a chi è seduto nel ponte mediano (Mid deck) di vedere gli effetti del plasma sull'orbiter durante questa fase (detta EI ovvero Entry Interface).
Per il resto esiste qualche immagine vista dalla ISS della scia di rientro dell'orbiter ma nulla di più (per ovvie problematiche tecniche :D) fino al momento in cui le Long Range Optical Tracking cameras cominciano ad intravedere l'orbiter a circa 80,000 piedi.
Per quanto concerne lo stato del rivestimento termico dello Shuttle, non crederai mica che lo lavano ad ogni missione vero? :D
Semplicemente le "mattonelle" in carbonio e il resto del rivestimento termico viene ricontrollato pezzo per pezzo e solo se necessario rimpiazzato. Per questo si notano i segni del rientro nell'atmosfera, che come si sa raggiunge il picco massimo di circa 3000°C.

Boh, comunque non mi sembra una cosa impossibile coi mezzi della nasa:
impossibile non so, ma praticamente impossibile si... ammesso che tu voglia buttare decine se non centinaia di milioni di dollari per non avere alcuna informazione interessante che non sia già nota... dovresti avere un altro velivolo che si muove a Mach 23 parallelamente all'orbiter... cosa alquanto difficile da realizzare... :D
D Poi nella descrizione della foto ho letto
