thumb|Comparison of International Space Station and [[Hubble Space Telescope orbits]] STS-400 was the Space Shuttle contingency support (Launch On Need) flight that would have been launched using if a major problem occurred on 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.
