Discovery lands!

BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: August 9, 2005

The shuttle Discovery's crew, braving the hellish fire of re-entry for the first time since Columbia's ill-fated descent two-and-a-half years ago, flew safely back to Earth today, gliding to a predawn California touchdown to close out an action-packed mission.

With veteran commander Eileen Collins at the controls, Discovery swooped to a ghostly, tire-smoking touchdown on runway 22 at Edwards Air Force Base in California's Mojave Desert at 8:11:22 a.m. EDT, one day late because of concern about cloudy weather in Florida. The crew had two shots at a Kennedy Space Center landing today, but off-shore storms forced entry flight director LeRoy Cain to divert the shuttle to California.

It was the 50th shuttle landing at the famed Air Force test center and only the sixth carried out in darkness. But Collins, a 1990 graduate of Air Force Test Pilot School at Edwards, had no problems, guiding Discovery to a picture-perfect touchdown.

Barreling down the runway at more than 200 mph, pilot James "Vegas" Kelly deployed a large braking parachute, the shuttle's nose dropped and the spaceplane slowly rolled to a halt.

"Houston, Discovery, wheels stopped," Collins radioed.

"Roger, wheels stopped, Discovery," called astronaut Ken Ham from mission control. "And congratulations on a truly spectacular test flight. Stevie Ray, Souichi, Andy, Vegas, Charley, Wendy and Eileen, welcome home, friends."

"Thank you, those are great words to hear," Collins replied. "We're happy to be back and we congratulate the whole team on a job well done."

Discovery's high-speed touchdown was the final chapter in the 114th shuttle mission, a voyage spanning 5.8 million miles and 219 complete orbits since blastoff July 26 from pad 39B at the Kennedy Space Center.

Collins, Kelly and their crewmates - flight engineer Stephen "Stevie Ray" Robinson, Andrew Thomas, Wendy Lawrence, Charles Camarda and Japanese astronaut Soichi Noguchi - were expected to climb out of the shuttle in about an hour for quick medical checks before a traditional walk-around inspection on the runway.

With Discovery back safely on the ground, NASA's full attention now shifts to figuring out what caused multiple pieces of foam insulation to fly off Discovery's external tank during launch. Columbia was brought down by wing damage caused by a foam debris strike during launch and the No. 1 priority of NASA's return to flight was fixing the insulation to minimize foam shedding.

But during Discovery's launch, a 0.9-pound chunk of foam peeled away from the tank just after solid booster separation. Two other relatively large pieces separated from the tank near the point where the shuttle's nose attaches to bipod struts and a fourth piece broke away from another area.

Media attention has focused on the largest piece, which came from a so-called protuberance air load - PAL - ramp designed to smooth the flow of supersonic air across pressurization lines and electrical cables. Going into Discovery's mission, the hydrogen PAL ramp, which was not modified in the wake of Columbia, had not suffered any known foam loss since 1983.

Last week, NASA confirmed that the area that broke away during launch had been slightly damaged and repaired, using standard procedures, during the tank's assembly at Lockheed Martin's Michoud, La., plant. NASA managers are hopeful whatever caused the foam to separate will be traced to an isolated problem with tank No. 121 and not a generic issue requiring a fleet-wide redesign.

But the PAL ramp foam is only part of NASA's problem and it's not yet known what might been needed to address the other areas of foam separation. One of those, from an area called the intertank flange, was modified in the wake of Columbia and engineers did not expect to see any significant debris.

The shuttle Atlantis had been scheduled for launch on the second post-Columbia mission in September, but resolution of the foam problem made that target window problematic. Now, with Discovery back on the ground in California, a September launch is no longer thought to be possible. Discovery must be ready for launch as a rescue vehicle in case Atlantis suffers any significant damage on its flight and today's West Coast landing will add a week or so to Discovery's turn-around time.

Atlantis' launch already had slipped to no earlier than Sept. 22, giving it just four days to get off the ground before the September launch window closes. It now appears Discovery will be unable to support that window, even if the foam problem can be resolved in time.

The only other available launch window before the end of the year is a three-day period in November. Another short window opens in January but the first lengthy opportunity to send a shuttle back to the international space station is in March.

Despite the disappointment over the launch-day foam events, Discovery's crew chalked up a near flawless mission, delivering tons of supplies to the space station and staging three spacewalks to install a new stabilizing gyroscope, an external tool and spare parts depot and to demonstrate potential heat-shield tile and wing leading edge repair techniques.

The astronauts also carried out an unprecedented inspection of the shuttle's heat shield, using a large sensor-equipped boom to examine the wing leading edges and nose cap and utilizing cameras on the station to photograph the orbiter's underside in great detail.

During that inspection, engineers spotted two protruding "gap fillers" sticking up from between tiles on Discovery's belly. Because of concern the gap fillers could trigger re-entry turbulence - and thus expose the underside tiles to extreme temperatures for longer periods - Robinson carried out emergency repairs during the crew's third spacewalk, plucking the gap fillers out with his gloved fingers.

The only other problem of any significance was a torn insulation blanket just below Collins' left-side cockpit window. After an extensive analysis, mission managers concluded Discovery could safely return to Earth as is and the damaged blanket was left in place.

Post-landing close-up television views showed most of the blanket survived Discovery's fiery re-entry with only minor signs of heat-related discoloration. It appared that a small section at the extreme front end of the thin, 20-inch-long blanket might have ripped away during Discovery's passage through the dense lower atmosphere, but the on-orbit analysis appeared to be vindicated.

Collins and company had hoped to land Monday in Florida, but off-shore clouds and rain forced a one-day delay. More of the same was on tap today, and after ordering the crew to pass up the first of two Florida landing opportunities, Cain diverted Discovery to California.

"How would you feel about a beautiful clear night with a breeze down the runway in the high desert of California?" Ham radioed around 5 a.m.

"We are ready for whatever we need to do," Collins replied.

"OK, that's going to be our plan," Ham said. "The official forecast is holding electrified clouds off the coast of the Cape, which we're not going to send you through."

Flying upside down and backward on a northwest to southeast trajectory over the Indian Ocean, Discovery's flight computers fired up the ship's twin orbital maneuvering system rockets at 7:06:18 a.m. for a two-minute 42-second burn that slowed the ship by 187 mph, just enough to drop the far side of the orbit deep into the atmosphere.

Collins then flipped the shuttle around, putting it in a wings-level, nose-up orientation at a 40-degree angle of attack. After a half-hour freefall, Discovery fell into the discernible atmosphere at an altitude of 400,000 feet - 75 miles - above the South Pacific Ocean.

Within minutes, Discovery was enveloped in a fireball as atmospheric friction converted the shuttle's energy of motion into heat. During Columbia's decent on Feb. 1, 2003, instruments on the shuttle recorded the first signs of abnormal heating just four minutes and 50 seconds after entry interface as plasma began.

But today, Discovery's fall to Earth appeared problem free as the shuttle streaked toward California.

Stanno spostando il Discovery verso l'hangar dove verrà predisposto per il trasporto con lo Shuttle Carrier Aircraft (SCA) al Kennedy Space Center tra circa una settimana.

Il volo dura almeno 2 giorni, dato che il Boeing 747 modificato non è in grado di essere rifornito in volo.

@GioFX

tratto da nasa.gov:

Discovery will be used for STS-121 instead of Atlantis, putting NASA in a better position for future missions to the Space Station. Atlantis will fly the following mission, STS-115, carrying Space Station truss segments which are too heavy to be carried by Discovery. By changing the lineup, the program won't have to fly back to back missions with Atlantis, as was previously scheduled.

non sapevo e soprattutto non pensavo che le differenze tra gli shuttle fossero di questa portata..
Di qui la mia domanda per GioFX ;) sai per caso che differenze ci sono tra i vari OV?


Tnx

In realtà non è esatto al 100% il report della NASA, in quanto il fatto principale per cui viene utilizzato nuovamente il Discovery e non l'Atlantis è che con il lancio previsto per NET (Not Earlier Then) il prossimo marzo, durante la prima finestra utile, è che scadono i termini di ri-ciclo dell'orbiter a causa della fine del periodo di certificazione per il volo di alcune componenti, principalmente i thrusters (RCS ed OMS) ed il propellente al monometil-idrazina (monomethil hydrazine, MMH) utilizzato.

Poi è vero, ci sono delle piccole differenze tra gli orbiter, anche se minime... una di queste è la dimensione totale del vano di carico (Payload Bay) che, nel caso del Discovery, è il più capiente in assoluto, intorno alle 28 tonnellate. E' l'unico che può portare due grossi segmenti (truss) che costituiscono lo scheletro su cui si uniscono i nodi centrali della stazione e su i quali sono attaccati i grossi pannelli solari e, appunto, i realtivi set di pannelli solari (due uno per ciascun segmento P). I quattro truss mancanti (ITS P3/P4, missione STS-115 e ITS P5/P6, STS-119) completeranno poi la parte americana, alla quale mancherà solo la Cupola.

Il problema è che il ritardo del ritorno a regime dei voli dello Shuttle ha ritardato e continua a ritardare l'invio in orbita dei moduli europei e giapponese, primo tra tutti il Columbus (già pronto da 3 anni all'EADS in Germania) che sono stati progettati apposta per essere lanciati con lo Shuttle, dato che nessun vettore espandibile, il russo Proton incluso, sono in grado di portare un modulo cosi largo.

Quindi in definitiva, dato che per la missione STS-115 che dovrà potare in orbita i segmenti P3 e P4, oltre ai set di pannelli solari 2A e 4A è necessario il Discovery, si è preferito utilizzare l'Atlantis per la STS-119 (che pur avendo due truss e relativi pannelli avrà un carico leggermente inferiore) che viene dopo la STS-121 (che porterà in orbita un altro modulo MLPM vettore... Leonardo), e quindi appuntto il Discovery di nuovo per la STS-115.

Questo anche perchè l'OV-105 (Endeavour) sarà pronto alla fine del 2006.

Non so se mi sono spiegato a sufficienza, altrimenti dimmi!

Quindi la timeline sarebbe:
marzo 06 STS-121 -> Discovery
2a finestra 06? STS-119 -> Atlantis
3a finestra 06? STS-115 -> Discovery
? ? ? -> Endeavour

..dal sito di Nasa.gov si capiva esattamente il contrario.. ;)

Stasera mi informo meglio e poi ti so dire con esattezza.

Cmq l'Endeavour sarò pronto per ottobre, in tempo per una missione. E la NASA e i suoi fornitori sono tecnicamente in grado di lanciare fino a nove missioni in un anno, ma è verosimile che, se non ci sono altri ritardi, che ne vengano effettuate almeno 4.


l'Endeavour e' attualmente in fase di riqualificazione per il volo?


E' in una fase che viene detta OMMP (Orbiter Major Modification Period), che è iniziata a fine 2002 dopo l'ultima missione prima della tragedia del Columbia nel febbraio 2003.
