STS-400 was the Space Shuttle contingency support (Launch On Need) flight that would have been launched using Space Shuttle Endeavour if a major problem occurred on Space Shuttle Atlantis during STS-125, the final Hubble Space Telescope servicing mission (HST SM-4).
Due to the much lower orbital inclination of the HST compared to the ISS, the shuttle crew would have been unable to use the International Space Station as a "safe haven," and NASA would not have been able to follow the usual plan of recovering the crew with another shuttle at a later date. Instead, NASA developed a plan to conduct a shuttle-to-shuttle rescue mission, similar to proposed rescue missions for pre-ISS flights. The rescue mission would have been launched only three days after call-up and as early as seven days after the launch of STS-125, since the crew of Atlantis would only have about three weeks of consumables after launch.
The mission was first rolled out in September 2008 to Launch Complex 39B two weeks after the STS-125 shuttle was rolled out to Launch Complex 39A, creating a rare scenario in which two shuttles were on launch pads at the same time. In October 2008, however, STS-125 was delayed and rolled back to the VAB.

STS (abbr. СТС from Russian: Сеть Телевизионных Станций, Set' Televizionnykh Stantsiy, Network of televisions stations) is a commercial television station based in Moscow, Russia. It belongs to the CTC Media, a Delaware-registered, Moscow-based NASDAQ-traded (CTCM) company with a market capitalization exceeding US$4 billion. The company is co-owned by National Media Group (Russia), Itera (Russia) and Modern Times Group (Sweden).
STS was launched on 1 December 1996 and today is a leading entertainment network in Russia. Focusing on entertainment, STS broadcasts a mix between Russian productions and international programming of interest to its target audience, viewers aged 6–54, especially younger audiences.
Approximately 100 million people are within STS’s signal reach. In 2007, STS achieved an average audience share in its target demographic of 11,3%. STS network reaches approximately 87% of urban households. It ranks as the fourth most watched nationwide broadcaster in Russia overall.
STS-114 was the first "Return to Flight" Space Shuttle mission following the Space Shuttle Columbia disaster. Discovery 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. 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.
This mission was to carry the Expedition 7 crew to the ISS and bring home the Expedition 6 crew. The original crew was to be:
