The mission would not have included the extended heatshield inspection normally performed on flight day two. Instead, an inspection would have been performed after the crew was rescued. On flight day two, Endeavour would have performed the rendezvous and grapple with Atlantis. On flight day three, the first EVA would have been performed. During the first EVA, Megan McArthur, Andrew Feustel and John Grunsfeld would have set up a tether between the airlocks. They would have also transferred a large size Extravehicular Mobility Unit (EMU) and, after McArthur had repressurized, transferred McArthur's EMU back to Atlantis. Afterwards they would have repressurized on Endeavour, ending flight day two activities. The final two EVA were planned for flight day three. During the first, Grunsfeld would have depressurized on Endeavour in order to assist Gregory Johnson and Michael Massimino in transferring an EMU to Atlantis. He and Johnson would then repressurize on Endeavour, and Massimino would have gone back to Atlantis. He, along with Scott Altman and Michael Good would have taken the rest of the equipment and themselves to Endeavour during the final EVA. They would have been standing by in case the RMS system should malfunction. The damaged orbiter would have been commanded by the ground to deorbit and go through landing procedures over the Pacific, with the impact area being north of Hawaii. On flight day five, Endeavour would have had a full heat shield inspection, and land on flight day eight. This mission could have marked the end of the Space Shuttle program, as it is considered unlikely that the program would have been able to continue with just two remaining orbiters, Discovery and Endeavour. On Thursday, 21 May 2009, NASA officially released Endeavour from the rescue mission, freeing the orbiter to begin processing for STS-127. This also allowed NASA to continue processing LC-39B for the upcoming Ares I-X launch, as during the stand-down period, NASA installed a new lightning protection system, similar to those found on the Atlas V and Delta IV pads, to protect the newer, taller Ares I rocket from lightning strikes.
== Emblem and Crew Patches ==
As a contingency mission, STS-400 was not given official support by NASA for the production of a crew patch or emblem. However artwork was created for use by the mission team as an unofficial emblem by Mike Okuda, who also illustrated the official patch of STS-125. As described by Paul F. Dye, Lead Flight Director of the mission, the emblem "adopts many of the elements seen in a rescue organization's patch - the square cross, bold letterers and border, and simple design. The idea is that the emblem instantly identifies the rescue organization in a crowd of others. In this case, the Shuttle outlines identify the purpose of our organization." In addition, the emblem contains 11 stars, symbolizing the combined 11 crew-members who would return to earth onboard STS-400. The first flight crew assigned to the mission created another, more humorous design depicting a St. Bernard with its traditional barrel of brandy replaced by the Hubble Space Telescope. The final flight crew though were unsatisfied with this as a crew patch, and contacted longtime NASA artist Tim Gagnon about creating a new one, but never formally approved a design before the mission was scrubbed.
