Shuttle Endeavour travels from one pad to the other
Space shuttle Endeavour switched launch pads at the Kennedy Space Center today, performing a "rollaround" in preparation for its November 14 ascent to the space station.
Se non ricordo male tra i rifornimenti trasportati da questa missione c'è il materiale necessario a preparare la ISS all'aumento dell'equipaggio da 3 a 6 persone :O

Endeavour to go Nov. 14; Hubble slips deeper into '09
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: October 30, 2008
NASA managers today cleared the shuttle Endeavour for launch Nov. 14 on a space station assembly and servicing mission. But work to test a component needed by the Hubble Space Telescope will not be finished in time for launch aboard the shuttle Atlantis in February. That flight, Hubble Servicing Mission 4, originally was scheduled for launch Oct. 14 but it was delayed when a critical science data relay unit aboard the observatory failed in late September. NASA managers decided to delay the Hubble flight to mid February to give engineers time to test replacement electronic gear, but detailed checkout and problems with the equipment require additional troubleshooting, officials said today, delaying the long-awaited flight to May at the earliest.

Debutta (http://www.nasaspaceflight.com/2008/10/safety-enhancements-dominate-sts-126-frr/) in STS-126 un buon numero di miglioramenti relativi alla sicurezza. Tre i punti principali:
Nelle ultime missioni è stata riscontrata una diminuzione del carburante rimasto nell'ET allo spegnimento degli SSME. Anche se i sensori ECO proteggono gli SSME dal funzionamento "solo ossigeno"/"solo idrogeno", in attesa che venga implementato il piano definivo per risolvere il problema (da STS-119 in poi), verrà aumentata la Control Mixture Ratio (CMR) a 6.049 mru.
Un aggiornamento del software di controllo dello Shuttle, che giunge alla versione OI-33. I miglioramenti riguardano:
- Una migliore gestione dell'RTLS abort (http://en.wikipedia.org/wiki/Space_Shuttle_abort_modes) che aumenta la probabilità di successo dal 96% al 99.67% in caso di che i GPC (General-purpose computer, i computer "di bordo" dello Shuttle) siano funzionanti e dal 84% al 96% nel caso non lo siano.
- Due nuove visualizzazioni sui display del cockpit e integrazione dei dati per migliorare la "conoscenza della situazione" dell'equipaggio e le sue capacità di selezione autonoma della giusta modalità di abort
http://static.howstuffworks.com/gif/space-shuttle-glass-cockpit2.jpg
Quattro nuove telecamere a infrarossi e 6 "normali" monitoreranno i "flame trench" del pad A (la struttura che convoglia gli scarichi degli SRB e degli SSME al lato del pad) che nell'ultima missione avevano subito dei danni con conseguente lancio di detriti (che comunque non avevano possibilità di colpire l'orbiter). Confermata l'istallazione di sensori per monitorare la condizione delle riparazioni effettuate.
Sono state aggiunte anche due nuove telecamere HD sulla Fixed Service Structure.
Da segnalare che eventuali LON (i lanci di soccorso in caso di problemi che impediscano il rientro dello Shuttle in orbita) viaggeranno nella stessa configurazione a loro assegnata per il lancio standard. In parole povere in caso si renda necessaria una missione di soccorso per STS-126 questa sarà lanciata con la stesso contenuto di STS-119 (il truss S6) e il Boundary Layer Transition DTO:
http://img205.imageshack.us/img205/5395/asdmq6.jpg
Veramente interessante, soprattutto l'ultima parte sulla configurazione di lancio... non lo sapevo.
Grazie Rand!
Traduco (alla buona) la parte sul Boundary Layer Transition DTO perché mi sembra interessante (la fonte è questo (http://www.nasaspaceflight.com/2007/12/sts-126-set-to-carry-out-special-reentry-experiment/) articolo).
Durante il rientro la compressione dell'aria ai bordi alari dello Space Shuttle forma uno strato che fa si che l'orbiter in quelle regioni subisca temperature intorno ai 2-3,000 gradi, mentre a pochissima distanza si raggiungono temperature fino a 10,000 gradi.
Irregolarità nel flusso d'aria a questi bordi innescano una passaggio del flusso da laminare a turbolento (boundary layer transition (http://en.wikipedia.org/wiki/Boundary_layer_transition)), il fenomeno si può visualizzare come: un fiume scorre uniforme, un grosso sasso che emerge dalla superficie fa si che si crei una perturbazione del flusso dietro di se. La turbolenza (nel caso del rientro) ha come conseguenza che le zone successive all'irregolarità siano esposte a temperature molto più elevate che in assenza di questo fenomeno.
Un danneggiamento a una mattonella dello Shuttle crea una di queste irregolarità: il problema è che esistono veramente pochi esperimenti che forniscano dati su cui basare i modelli/simulazioni per determinare se un dato danneggiamento è abbastanza rilevante da dare problemi in seguito alle aumentate temperature, a che velocità, ecc.
Tramite l'utilizzo di una piastrella opportunamente modificata posizionata vicino al portellone dei carrelli
http://img205.imageshack.us/img205/5395/asdmq6.jpg
si provocherà volutamente il "boundary layer transition" a una velocità <= mach 15 per misurarne gli effetti sull'area successiva tramite appositi sensori (termocoppie).
L'area "del carrello" è stata appositamente scelta perché l'eventualità che pezzi di ghiaccio/schiuma provochino danni addizionali è molto remota e anche un elevata perturbazione del flusso non è un rischio per l'orbiter (numerose prove "di riscaldamento" e di impatto di detriti sono state svolte per validare la sicurezza dell'esperimento).
In caso di problemi sarà comunque possibile rimuovere la protuberanza durante un EVA.
Se l'esperimento sarà un successo nei voli successivi verrà verificata la "transizione" anche a mach 18 e successivamente a mach 19. Un ultima fase vede l'aggiunta di una copertura in materiale catalizzatore per testarne le interazioni col flusso turbolento.
Veramente interessante, soprattutto l'ultima parte sulla configurazione di lancio... non lo sapevo.
Grazie Rand!
Ho pensato che un paio di notizie sugli interventi che migliorano la sicurezza non erano una brutta cosa.. :D

All systems looking good for Endeavour's launch on Friday
BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: November 12, 2008
The shuttle Endeavour's countdown began on time Tuesday night and with no technical issues of any significance, NASA's Mission Management Team today cleared the spacecraft for launch Friday on a critical space station assembly and maintenance mission. Liftoff is targeted for 7:55:34 p.m. Friday and forecasters continue to predict a 60 percent chance of acceptable weather.
"At the end of the discussion we determined we don't have any open issues, no open work, no open constraints," said MMT Chairman LeRoy Cain. "So we're ready to go, the vehicle, the crew and the ground teams have prepared very hard for this mission. We were postured to fly a different mission just a month or so ago. But we were always planning on flying this mission this Fall, and so we're ready to go do that now."

1845 GMT (1:45 p.m. EST)
FUELING COMPLETED. The external fuel tank has been pumped full with a half-million gallons of supercold liquid oxygen and liquid hydrogen. The three-hour fueling process started at 10:40 a.m. with the chilldown conditioning and was completed at 1:31 p.m.
But given the cryogenic nature of the oxidizer and propellant, the supplies naturally boil away. So the tanks are continuously topped off until the final minutes of the countdown in a procedure called "stable replenishment."
With the hazardous tanking operation completed, the Orbiter Closeout Crew and Final Inspection Team have been given the OK to go out to the pad to perform their jobs. The closeout crew will ready Endeavour's crew module for the astronauts' ingress in a couple of hours; and the inspection team will give the entire vehicle a check for any ice formation following fueling.

2230 GMT (5:30 p.m. EST)
T-minus 90 minutes and counting. Countdown clocks continue to tick down to T-minus 20 minutes where the next hold is planned. Countdown activities remain on track for liftoff at 7:55 p.m. There are no technical issues being worked and weather continues to be acceptable.
At this point in the count, the Ground Launch Sequencer software that will control the final nine minutes of the countdown has been initialized. Also, the solid rocket boosters' gas generator heaters in the hydraulic power units are turned on, the aft skirt gaseous nitrogen purge is starting and the rate gyro assemblies (RGAs) are being activated. The RGAs are used by the orbiter's navigation system to determine rates of motion of the boosters during the first stage of flight.
2355 GMT (6:55 p.m. EST)
Now one hour away from launch of Endeavour.
Pilot Eric Boe is configuring the displays inside Endeavour's cockpit for launch while commander Chris Ferguson enables the abort steering instrumentation.
Molto bella l'immagine con la luna che si vedeva prima..
0001 GMT (7:01 p.m. EST Fri.)
T-minus 9 minutes and holding. Countdown clocks have gone into the planned 45-minute, 39-second built-in hold. Today's launch remains set for 7:55:39 p.m. EST.

Mi iscrivo al thread.. a settembre sono stato per la seconda volta al kennedy space center e ho visto con i miei occhi l'Endeavour e l'Atlantis dockati insieme sul 39B e A.. poi ci sono stati i casini che tutti sappiamo.. hanno trasferito l'Endeavour sulla A e rimesso a dormire l'Atlantis.. e oggi siamo qui, pronti a seguire una nuova missione ;)
Godspeed Endeavour ;)
0035 GMT (7:35 p.m. EST Fri.)
Now 20 minutes from Endeavour's launch on an eight-and-a-half minute trek to space. At main engine cutoff, Endeavour will be flying on a suborbital trajectory with a high point of 136 statute miles and low point of 36 statute miles. A half-hour later, the twin orbital maneuvering engines will be fired to place the shuttle into a 142 by 121 mile orbit.

Crew spends first day in space inspecting Endeavour
The shuttle Endeavour is in good shape after its climb to space Friday and engineers are only working a handful of relatively minor problems, most noticeably glitches with the shuttle's KU-band antenna. Based on an evening video inspection, a presumably lost strip of flexible insulation from the shuttle's left aft fuselage apparently is still in place.

STS-126: MPLM attached to ISS - ET-129 images show extremely clean tank
November 17th, 2008 by Chris Bergin
...
The Mission Management Team (MMT) are continuing to evaluate the huge array of imagery gained on Endeavour’s ascent on Friday, via FD2 and FD3 inspections, with several items still being worked by the Damage Assessment Team (DAT).
Items of interest include a couple of areas of minor - almost cosmetic - damage to the aft of Endeavour, such as OMS Pod tiles and the SSME (Space Shuttle Main Engine) dome heat shield. They are likely to be cleared.
“Port Side T-0 FRSI and TPS nominal - additional imagery provided data. LH2 T-0 plate 16 mm film review completed by KSC imagery Team. Identified potential of solid ice in the area - dimensions being determined,” noted a TPS presentation on L2, referencing what was initially thought to be a strip of thermal blanket.
“AFT Flight Deck Complete - OMS Pod discrepancies noted: 4 Gap Fillers protruding frayed/2 Tile Damages. LESS Carrier Panel Inspection Complete - No damages identified.”
Importantly, no damage has been observed on Endeavour’s critical TPS systems, as evaluations into RPM imagery (selection available in L2) continue.
The first area to be cleared was the starboard side of the vehicle - which was required ahead of MPLM unberthing, due to clearance issues with the OBSS (Orbiter Boom Sensor System), had a Focused Inspection been required.
“All RPM imagery has been downlinked and is being reviewed by the Damage Assessment Team (DAT). In addition, the DAT has been reviewing the SRMS survey imagery,” noted information on Monday. “The Orbiter Project Office (OPO) cleared the starboard side of the vehicle and gave Flight Control a go for MPLM unberthing on FD 4.
“The Reinforced Carbon-Carbon (RCC) Leading Edge Subsystem (LESS) had no focused inspection (FI) requirements for the starboard or port wings or the nose-cap. The DAT is analyzing the imagery to formally clear the regions of interest for the FD 4 OPO (Orbiter Project Office) meeting.
“The Thermal Protection System (TPS) had no FI (Focused Inspection) candidates on the starboard side. There are some protruding gap fillers at various locations, tile coating damage near the Left-Hand (LH) External Tank (ET) door tile with shallow damage and a broken dome heat shield tile.
“The DAT is continuing the analysis process and is confident that these areas will be cleared.”
One gap filler referenced has been observed to be slightly protruding from below a RCC panel. It’s specific location is not yet documented. Another - less protruding - gap filler is also observed further down the wing.
While these will likely be cleared for re-entry, such a process may take slightly longer than most areas, due to the computational models required for how the gap fillers will ‘perform’ during re-entry. However, as of FD4, Endeavour has been cleared from any requirement of a Focused Inspection - a sign of how clean the orbiter is of damage.
The lack of any damage to Endeavour’s RCC panels and underbelly is thanks to what appears to be an amazing performance by ET-129’s TPS. Images taken from Endeavour’s umbilical well show a pristine tank, with only three very minor areas of foam loss.
A huge amount of improvements to the ET by engineers at Lockheed Martin’s Michoud Assembly Facility (MAF) since Return To Flight appear to be paying off, with no major foam loss from the tanks since STS-121.
Modifications will continue to take place on the tanks - although some items have been cancelled due to the vastly improved performance of late - with the end goal of making the final tank to fly with the shuttle the safest ever.
In particolare l'external tank utilizzato in questa missione (ET-129) si è comportato straordinariamente bene, con solo 3 aree "molto piccole" che mostrano segni di perdita di schiuma.
PS. A quanto pare l'equipaggio è avanti di 2 ore e 15 minuti rispetto alla tabella di marcia
E' cominciata la EVA-1.

Qualche problema durante l'EVA: la pistola spara grasso è "esplosa" nella borsa degli strumenti, ingrassando tutto :D
Heidi reports that a grease gun "Exploded" (her words) in the ORU bag, grease is on a camera, her gloves, sounds like a mess.
la borsa degli strumenti, diventata scivolosa, è sfuggita:
Uh oh, liberated tool bag! She had all that grease everywhere and it simply slipped away.
Toolbag decides it wants a new life as MMOD aswell. Come back!!
Comunque ne esiste una di riserva, quindi il lavoro continua:
And typically NASA, they've got contingency. Steve's got duplicate equipment in his bag.
Armageddon line time: "At NASA we don't take chances, we double up on everything".
Nonostante il piccolo intoppo l'EVA sta procedendo bene, i due astronauti stanno eseguendo le operazioni di manutenzione sul SARJ.
Rispetto alla scaletta dell'EVA sono attualmente in anticipo di 20-25 minuti.

Umh..guardando meglio nel video lo chiamano CIR, non CIRS come nelle informazioni sul video. Piccola inesattezza :D
Comunque è il Combustion Integrated Rack (http://www.nasa.gov/mission_pages/station/science/experiments/CIR.html):
The Combustion Integration Rack (CIR) is used to perform combustion experiments in microgravity. The CIR is designed to be easily reconfigured on-orbit to accommodate a wide variety of combustion experiments. It consists of an optics bench, a combustion chamber, a fuel and oxidizer management system, environmental management systems, interfaces for science diagnostics and experiment specific equipment. For diagnostic purposes, there will be 5 different cameras available for use by the investigator. The CIR features a 100-liter combustion chamber surrounded by optical and other diagnostic packages including a gas chromatograph. Experiments are conducted in the chamber by remote control from the Glenn Research Center (GRC) Telescience Support Center (TSC).
Poi sbaglio o su nasa.gov scarseggiano i viedeo della missione?!
Non so.. di solito guardo lo streaming su NASA TV, non i video separati. Comunque questo (http://www.space-multimedia.nl.eu.org/index.php?option=com_content&task=category§ionid=1&id=1&Itemid=19) sito presenta molti spezzoni.

Weather delays shuttle landing at least one orbit
Faced with a bleak weather forecast for the Kennedy Space Center, re-entry preparations aboard the space shuttle Endeavour have been delayed and the first landing opportunity of the day officially scrubbed. A second Florida landing option one orbit later remains a possibility, but a detour to Edwards Air Force Base in California this afternoon appears more likely. Meanwhile, a Russian resupply ship docked to the space station via remote control this morning after the automated rendezvous system had a problem.

1553 GMT (10:53 a.m. EST)
WAVE OFF 2. Mission Control just scrapped today's second landing opportunity into Kennedy Space Center. However, no decision has been made about diverting to Edwards Air Force Base, California. Entry flight director Bryan Lunney wants to look at tomorrow's weather forecast for KSC before making the final call.
The remaining landing opportunities today and those available tomorrow:

CALIFORNIA BOUND. With the forecasts predicting unfavorable weather at Florida's Kennedy Space Center proving true today and little hope of better conditions tomorrow, NASA has decided to divert space shuttle Endeavour's landing to the backup site at Edwards Air Force Base, California.
The deorbit burn is scheduled for 3:19 p.m. EST (12:19 p.m. local; 2019 GMT), leading to touchdown at 4:25 p.m. EST (1:25 p.m. local; 2125 GMT) to conclude the 16-day flight.
Ideal weather conditions await the shuttle in California's Mojave Desert today. At landing time, meteorologists are expecting just a few clouds at 30,000 feet, good visibility and northeasterly winds of 6 peaking to 11 knots down the runway.
As for viewing the landing in person, the following information was issued by NASA:
Although the main portion of Edwards Air Force Base will NOT be open to the public for viewing of a potential space shuttle landing, base officials advised Saturday afternoon that the remote east lakebed viewing area off Mercury Boulevard will be open for public viewing. The Mercury Boulevard viewing site is accessible from 120th and 140th Streets East from the south side of the base east of Lancaster, and from Highway 58 off Twenty Mule Team Road west of Boron. Visitors should allow for an additional 45 minutes driving time from the south gate security station on 120th Street East and 30 minutes additional driving time from the Highway 58 exit. Air Force security officers will be on hand to direct traffic beginning at 10 a.m. Sunday.

GO FOR THE DEORBIT BURN! Entry flight director Bryan Lunney in Mission Control just gave approval for Endeavour to perform the deorbit burn at 3:19:29 p.m. EST that will commit the shuttle for the trip back to Earth.
Touchdown at Edwards Air Force Base in California is set for 4:25 p.m. EST.
2019 GMT (3:19 p.m. EST)
DEORBIT BURN IGNITION. Flying upside down and backwards 220 miles above the Indian Ocean, Endeavour 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 54 seconds, slowing the craft by about 200 mph to slip from orbit. The retro-burn will send Endeavour to Edwards Air Force Base in California for a touchdown at 4:25 p.m. EST.
2022 GMT (3:22 p.m. EST)
DEORBIT BURN COMPLETE. Endeavour has successfully completed the deorbit burn for the journey back from space. Landing is scheduled for 4:25 p.m. EST at Edwards Air Force Base in California to complete this 16-day mission to the international space station.
2035 GMT (3:35 p.m. EST)
Touchdown is 50 minutes away. This will be the 52nd shuttle landing at Edwards Air Force Base, the 46th to occur in daylight and the first since June 22, 2007 when Atlantis landed there to conclude STS-117.
2053 GMT (3:53 p.m. EST)
ENTRY INTERFACE. Endeavour's 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.
Touchdown remains set for 4:25 p.m. EST in the Mojave Desert.
2115 GMT (4:15 p.m. EST)
Ten minutes from landing. Endeavour is approaching the coast of Southern California.
2116 GMT (4:16 p.m. EST)
Tally ho on Endeavour. Powerful tracking cameras at the landing site have spotted the descending shuttle.
2119 GMT (4:19 p.m. EST)
Mach 2, altitude 13 miles, 47 miles from the runway.
Eccolo :D
Alzato il volume per il booom
2120 GMT (4:20 p.m. EST)
The twin sonic booms have rumbled across the Edwards Air Force Base area, announcing the shuttle's arrival.
2121 GMT (4:21 p.m. EST)
The shuttle is in the Heading Alignment Cylinder, an imaginary circle to align with Runway 04L. Commander Chris Ferguson is piloting Endeavour through a 340-degree left-overhead turn over the Mojave Desert to loop around for landing on the southwest to northeast runway.

WHEELS STOP. The voyage of space shuttle Endeavour that remodeled the interior of the international space station and prepared the outpost for doubling the size of its resident crews has safely and successfully concluded. The 16-day marathon also featured four spacewalks that cleaned and lubricated the space station's damaged starboard-side solar array paddle wheel joint and performed preventive maintenance on the port-side joint.

Fine della missione!
Grazie a tutti!
"happy to be in california" .. anche no, gli costerà due milioncini il trasferimento a cape kennedy :asd:
circa 1 milione secondo le stime.
Cmq sicuramente a loro va bene... 18° a dicembre... :D

mi prendi impreparato, ci sono un sacco di variabili in gioco, credo che solo GioFX può provare a rispondere

Hanno ovviamente valutato le condizioni al KSC anche per domani, per le quali è stato deciso un NO-GO, e quindi la scelta su Edwards già oggi.
Se non sbaglio domani il tempo in Florida è previsto leggermente migliore ma con gli stessi forti venti laterali.

ok, ma se fosse stato possibile scendere domani al KSC, quale soluzione sarebbe stata da preferire, economicamente parlando?
Ciao e a risentirci nel 2009 per sts-125

Il KSC è sempre la prima scelta, quindi se considerate tutte le condizioni (meteo in testa) c'è un "GO", allora si atterra in Florida.
Se c'è la possibilità che le condizioni meteorologiche siano soddisfacenti, e se ovviamente è possibile posticipare il ri-entro, allora il controllo missione ordina sempre uno scrub con nuovo tentativo il giorno seguente.

Azz, tornato adesso :mad:
Comunque le manutenzione al SARJ che dava problemi sembra aver dato buoni frutti:
A two orbit Autotrack test was carried out on the starboard SARJ, following EVA-4, with initial data proving to be positive on the improvements to the rotating joint’s health - via less vibration and lower currents required to drive the motors.
“Port SARJ returned to autotrack operation post-EVA. Drive current levels slightly less after lubing,” noted Mission Management Team (MMT) documentation on L2.
“Starboard SARJ autotrack test performed; required significantly less current to drive: currents were 0.7 - 0.9A prior to lube, currents were 0.17A average and 0.35A peak after lube.”
While the data will take up to two months to fully analysis, managers are already hopeful of the possibility that the starboard SARJ won’t require renewed cleaning and lubrication on a regular basis. More so, a long term plan for the SARJ - which was mapped out during the summer - may not be required.
That plan involved several downstream missions including SARJ ‘clean and lube’ requirements, before the long-term solution of replacing the Race Ring - a plan known as SARJ XL - was initiated.
SARJ XL is classed as “an innovative scheme to potentially take the single spare race ring and insert it between the existing spalled inboard race ring, and the other spare ‘outboard’ race ring.”
At present, engineers are pressing ahead to launch SARJ XL on one of the CLF (Contingency Logistics Flight) missions in 2010, with that mission’s EVAs dedicated towards its installation.
“Trade Study: (ISS Manager) Mr. (Mike) Suffredini had asked about accelerating SARJ XL to ULF4 from ULF5 (ULF5 is the last mission in the “current” manifest). Due to various reasons, many due to hardware availability, the SSPCB directed the SARJ XL to stay on ULF5,” noted the latest news via a MOD memo, on L2, prior to the mission.
Se va tutto bene basterà una manutenzione annuale tramite un EVA e non ci sarà bisogno di sostituire il pezzo (SARJ XL)
