Denne artikel handler om en mission i rumfærge-programmet. For informationer om programmet se rumfærge-programmet.

STS-131 (Space Transportation System-131) er rumfærgen Discoverys 38. rummission. Den blev opsendt den 5. april 2010 klokken 12:21 dansk sommertid (6:21 am EDT). Discovery landede tirsdag d. 20. april klokken 15:08 (9:08 am EDT) på Kennedy Space Center i Florida.

Missionen medbragte forsyninger til Den Internationale Rumstation (ISS) med Multi-Purpose Logistics Module (MPLM) containeren Leonardo[1].

Missionen

Den defekte TDRS Kubånds-antenne.
Rumfærgen Discovery opsendes fra Kennedy Space Center i Florida d. 5. april 2010.

Discovery blev opsendt den 5. april 2010 klokken 6:21 am EDT fra Kennedy Space Center i Florida [2] [3].

Rumfærgens parabolantenne (og Ku-båndsantenne), der normalt sættes op så snart rumfærgen har åbnet til lastrummet i kredsløb, kom ikke til at fungere. Antennen er en del af TDRS-systemet, der er et netværk af kommunikationssatellitter, som NASA benytter til kommunikation med bl.a. rumfærgerne. NASA benyttede andre metoder til at overføre de data-mængder der plejer at blive transmitteret med parabolen, men dataoverførslerne tog længere tid[4] [5]. Højopløsningsbillederne af varmeskjoldet blev uploadet med rumstationens højhastighedsantenner. Parabolantennen skulle også anvendes af et radarsystem til at måle afstanden til ISS, men besætningen brugte optiske metoder.

NASA meddelte at en enkelt kakkel ved sideroret muligvis var faldet af rumfærgen under opsendelsen. Hændelsen blev ikke regnet for at kunne gøre skade ved indflyvningen i Jordens atmosfære, når rumfærgen vendte tilbage[6].

Efter rumfærgens sammenkobling med rumstationen var der for første gang 4 kvinder om bord på rumstationen samtidig [7].

Tre rumvandringer blev fuldført af Rick Mastracchio og Clayton Anderson, men ikke uden problemer. Astronauterne havde problemer med at få bolte og skruer ind i deres huller[8] [9] [10].

Der var også problemer med at få sat Leonardo tilbage i rumfærgens lastrum [11].

STS-131 EVA3 Clayton Anderson 3.jpg
NASA astronaut Clayton Anderson, STS-131 mission specialist, participates in the mission's third and final session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 24-minute spacewalk, Anderson and astronaut Rick Mastracchio (out of frame), mission specialist, hooked up fluid lines of the new 1,700-pound tank, retrieved some micrometeoroid shields from the Quest airlock's exterior, relocated a portable foot restraint and prepared cables on the Zenith 1 truss for a spare Space to Ground Ku-Band antenna, two chores required before space shuttle Atlantis' STS-132/ULF-4 mission in May.

STS131-leonardo-preparations2.jpg
In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the Multi-Purpose Logistics Module Leonardo is filled with platforms and racks for its upcoming flight. The seven-member STS-131 crew will deliver Leonardo, filled with resupply stowage platforms and racks, to the International Space Station aboard space shuttle Discovery. On STS-131, work to attach a spare ammonia tank assembly to the station's exterior and return a European experiment from outside the station's Columbus module will be conducted during three spacewalks. Targeted for launch on April 5, STS-131 will be the 33rd shuttle mission to the station and the 131st shuttle mission overall.
STS-132 patch.png
The STS-132 mission will be the 32nd flight of the space shuttle Atlantis. The primary STS-132 mission objective is to deliver the Russian-made MRM-1 (Mini Research Module) to the International Space Station (ISS). Atlantis will also deliver a new communications antenna and a new set of batteries for one of the ISS solar arrays. The STS-132 mission patch features Atlantis flying off into the sunset as the end of the Space Shuttle Program approaches. However the sun is also heralding the promise of a new day as it rises for the first time on a new ISS module, the MRM-1, which is also named Rassvet, the Russian word for dawn.
STS-131 MPLM Leonardo preparations 1.jpg
CAPE CANAVERAL, Fla. - In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, processing of Multi-Purpose Logistics Module Leonardo is under way for its trip to the International Space Station aboard space shuttle Discovery on the STS-131 mission. The science racks Leonardo delivers will be transferred to laboratories on the station. Three spacewalks during STS-131 will include work to attach a spare ammonia tank assembly to the station's exterior and return a European experiment from outside the station's Columbus module. STS-131 will be the 33rd shuttle mission to the station. Launch is targeted for March 18, 2010.

NASA astronauts Rick Mastracchio (left) and Clayton Anderson, both STS-131 mission specialists, participate in the mission's second session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the seven-hour, 26-minute spacewalk, Mastracchio and Anderson unhooked and removed the depleted ammonia tank and installed a 1,700-pound ammonia tank on the station's Starboard 1 truss, completing the second of a three-spacewalk coolant tank replacement process.

NASA astronaut Rick Mastracchio, STS-131 mission specialist, participates in the mission's first session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, 27-minute spacewalk, Mastracchio and astronaut Clayton Anderson (out of frame), mission specialist, helped move a new 1,700-pound ammonia tank from space shuttle Discovery's cargo bay to a temporary parking place on the station, retrieved an experiment from the Japanese Kibo Laboratory exposed facility and replaced a Rate Gyro Assembly on one of the truss segments.
STS-131 launching from Kennedy Space Center.jpg
Space shuttle Discovery's launch is brilliant as it lifts off Launch Pad 39A at NASA's Kennedy Space Center in Florida at 6:21 a.m. EDT April 5 to begin the STS-131 mission. The seven-member crew will deliver the multi-purpose logistics module Leonardo, filled with supplies, a new crew sleeping quarters and science racks that will be transferred to the International Space Station's laboratories. The crew also will switch out a gyroscope on the station's truss, install a spare ammonia storage tank and retrieve a Japanese experiment from the station's exterior. STS-131 is the 33rd shuttle mission to the station and the 131st shuttle mission overall.
STS-131 patch.png
The STS-131/19A crew patch highlights the Space Shuttle in the Rendezvous Pitch Maneuver (RPM). This maneuver is heavily photographed by the International Space Station (ISS) astronauts, and the photos are analyzed back on earth to clear the Space Shuttle's thermal protection system for re-entry. The RPM illustrates the teamwork and safety process behind each Space Shuttle launch. In the Space Shuttle's cargo bay is the Multi-Purpose Logistics Module (MPLM), Leonardo, which is carrying several science racks, the last of the four crew quarters, and supplies for the ISS. Out of view and directly behind the MPLM, is the Ammonia Tank Assembly (ATA) that will be used to replace the current ATA. This will take place during three Extra Vehicular Activities (EVAs). The 51.6° Space Shuttle orbit is illustrated by the three gold bars of the astronaut symbol, and its elliptical wreath contains the orbit of the ISS. The star atop the astronaut symbol is the dawning sun, which is spreading its early light across the Earth. The background star field contains seven stars, one for each crewmember; they are proud to represent the United States and Japan during this mission.
STS-130 patch.png
The official patch for STS-130. The shape of the patch represents the Cupola, which is the windowed robotics viewing station, from which astronauts will have the opportunity not only to monitor a variety of ISS operations, but also to study our home planet. The image of Earth depicted in the patch is the first photograph of the Earth taken from the moon by Lunar Orbiter I on August 23, 1966. As both a past and a future destination for explorers from the planet Earth, the moon is thus represented symbolically in the STS-130 patch. The Space Shuttle Endeavour is pictured approaching the ISS, symbolizing the Space Shuttle's role as the prime construction vehicle for the ISS.
