Discovery STS-114 Return To Flight
Posted On 06/13/2017 14:55:01 by mandy40

hello folks this is Mandy, i had a page here before dedicated to the return to flight mission Discovery STS-114 the first space shuttle flight after Columbia but i decided to delete it and keep my current one, this is a combination of my main page and a tribute to the sts-114 crew of discovery. (ALSO I WILL BE ADDING BACK A FEW VIDEOS I HAD ON THAT PAGE AS WELL) here below is a summary that i had taken off wikipedia from that mission. after reading if anybody is interested in adding me on you can.


i currently have my page set to private at the moment but to point out to everyone that i only accept plain typed up comments mainly due to i will only be on here between 1 to 5 days a week with my part time job as a front end service clerk a.k.a bagger at a small chain grocery store that is gradually expanding and i am on rotating days and hours. in closing i will also be providing a link below after the sts-114 summary here if anybody is interested in reading futher information. if nobody wishes to not to add me that is ok i understand. thank you for stopping by all i wish you all the best. now without futher or do:


STS-114 was the first "Return to Flight" Space Shuttle mission following the Space Shuttle Columbia disasterDiscovery launched at 10:39 EDT (14:39 UTC), 26 July 2005. The launch, 907 days (approx. 29 months) after the loss of Columbia, was approved despite unresolved fuel sensor anomalies in the external tank that had prevented the shuttle from launching on 13 July, its originally scheduled date.

The mission ended on 9 August 2005 when Discovery landed at Edwards Air Force Base in California.[2]Poor weather over the Kennedy Space Center in Florida hampered the shuttle from using its primary landing site.

Analysis of the launch footage showed debris separating from the external tank during ascent; it was the issue that had set off the Columbia disaster. As a result, NASA decided on 27 July to postpone future shuttle flights pending additional modifications to the flight hardware. Shuttle flights resumed a year later with STS-121 on 4 July 2006.

Mission highlights


STS-114 marked the return to flight of the Space Shuttle after the Columbia disaster and was the second Shuttle flight with a female commander (Eileen Collins, who also commanded the STS-93 mission). The STS-114 mission was initially to be flown aboard the orbiter Atlantis, but NASA replaced it with Discovery after improperly installed gear was found in Atlantis' Rudder Speed Brake system. During OMM for Discovery, an actuator on the RSB system was found to be installed incorrectly. This created a fleet wide suspect condition. The Rudder Speed Brake system was removed and refurbished on all three remaining orbiter vehicles, and since Discovery's RSB was corrected first, it became the new Return to Flight vehicle, superseding Atlantis. Seventeen years prior, Discovery had flown NASA's previous Return to Flight mission, STS-26.

The STS-114 mission delivered supplies to the International Space Station. However, the major focus of the mission was testing and evaluating new Space Shuttle flight safety techniques, which included new inspection and repair techniques. The crewmembers used the new Orbiter Boom Sensor System (OBSS) – a set of instruments on a 50-foot (15 m) extension attached to the Canadarm. The OBSS instrument package consists of visual imaging equipment and a Laser Dynamic Range Imager (LDRI) to detect problems with the shuttle's Thermal Protection System (TPS). The crew scanned the leading edges of the wings, the nose cap, and the crew compartment for damage, as well as other potential problem areas engineers wished to inspect based on video taken during lift-off.

STS-114 was classified as Logistics Flight 1. The flight carried the Raffaello Multi-Purpose Logistics Module, built by the Italian Space Agency, as well as the External Stowage Platform-2, which was mounted to the port side of the Quest Airlock. They deployed MISSE 5 to the station's exterior, and replaced one of the ISS's Control Moment Gyroscopes (CMG). The CMG was carried up on the LMC (Lightweight Multi-Purpose Experiment Support Structure Carrier) at the rear of the payload bay, together with the TPS Repair Box.

Stephen Robinson on the third spacewalk

The crew conducted three spacewalks while at the station. The first demonstrated repair techniques on the Shuttle's Thermal Protection System. During the second, the spacewalkers replaced the failed gyroscope. On the third, they installed the External Stowage Platform and repaired the shuttle, the first time repairs had been carried out during a spacewalk on the exterior of a spacecraft in flight. On 1 August, it was announced that protruding gap fillers on the front underside of the shuttle would be inspected and dealt with during the third spacewalk of the mission. The spacewalk was conducted on the morning of 3 August. Robinson easily removed the two fillers with his fingers. Later on the same day, NASA officials said that they were looking closely at a thermal blanket located next to the commander's window on the port side of the orbiter. Published reports on 4 August 2005 said that wind tunnel testing had demonstrated that the orbiter was safe to re-enter with the billowed blanket.


On 30 July 2005, NASA announced that STS-114 would be extended for one day, so that Discovery's crew could help the ISS crew maintain the station while the shuttle fleet was grounded. The extra day was also used to move more items from the shuttle to the ISS, as uncertainty mounted during the mission as to when a shuttle would next visit the station. The orbiter's arrival also gave the nearly 200-ton space station a free altitude boost of about 4,000 feet (1,220 m). The station loses about 100 feet (30 m) of altitude a day.

The shuttle hatch was closed the night before it undocked from the ISS. After undocking, the shuttle flew around the station to take photos.

Atmospheric reentry and landing was originally planned for 8 August 2005, at Kennedy Space Center, but unsuitable weather postponed the landing until the next day, then moved it to Edwards Air Force Base in California, where Discovery touched down at 08:11EDT (05:11 am PDT, 12:11 UTC).
