STS-400: The planned (if needed) rescue of STS-125

Unofficial crew patch *

On LC-39A STS-125 Atlantis (left) and on LC-39B is STS-400 Endeavour (right).

In the wake of the Columbia Tragedy, NASA prepared several contingency missions in the event a shuttle could not return safely. Most of the shuttle missions post STS-107, involved the construction/support of the International Space Station. If there were any instances where the shuttle was deemed unfit to return safely, the crew would stay on the ISS until a relief shuttle could be sent. However, STS-125 Atlantis was to service the Hubble Space Telescope and was not on the same orbital plane as the ISS. The Atlantis wouldn't have enough fuel to reach the station, so another Shuttle (Endeavour) was kept on standby on LC-39B. STS-400 would have been crewed by Christopher Ferguson, Eric A. Boe, Robert S. Kimbrough and Stephen G. Bowen.

On the first day, the crew of Atlantis would use the Canadarm to inspect the bottom of the shuttle for damage to the Thermal Protection System. Had there been any damage deemed unrepairable, the plan was to launch Endeavour 5 days later. Atlantis would be put into powered-down mode to conserve power and consumables.

Endeavour will have Altitude Control with Atlantis serving as a Micro-Meteoroid Orbiting Debris shield.

"On flight day two, Endeavour would have performed the rendezvous and grapple with Atlantis."

Crew locations during EVA-1

"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."

Crew locations during EVA-2

Crew locations during EVA-3

"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."

STS-400 Middeck Seating

The additional crew members on Endeavour would have been accommodated via additional seats installed on the middeck. The autopilot onboard Atlantis would be used to de-orbit the orbiter tail first, to destroy it over a region north of Hawaii, in the Pacific Ocean.

Another unofficial crew patch.

View from LC-39B of the launch of STS-125 Atlantis on May 11, 2009. This was the fifth and final Space Shuttle mission to the Hubble Space Telescope.

Fortunately, STS-400 was not needed and Endeavour was returned to the VAB from LC-39B for STS-127.

* "As a contingency mission, STS-400 was not given official support by NASA for the production of a crew patch or emblem. However this artwork was created for use by the mission team as an unofficial emblem by Mike Okuda [the same person who worked on Star Trek and most of the LCARS], who also illustrated the official patch of STS-125, the flight to be rescued by STS-400."

I keep seeing @aemiron-main & co's post about the connections between the Creels and the Wheelers and one of these days we're gonna have to have a long and detailed talk about how that plays into this Prisoners analysis I'm doing--

--because if I don't talk to someone about the fact that the primary antagonist in that movie (the movie the Duffers based their whole pitch on) is trying to get back at humanity for the things that were taken from them (a child) and how she mirrors Henry in 2.5M ways and is named (I kid you not) Holly I'm gonna lose my mind

"Space Shuttle Atlantis (foreground) sits on Launch Pad A and Endeavour on Launch Pad B at NASA's Kennedy Space Center in Florida. At the left of each shuttle are the open rotating service structures with the payload changeout rooms revealed. The rotating service structures provide protection for weather and access to the shuttle.

For the first time since July 2001, two shuttles are on the launch pads at the same time. Endeavour stands by at pad B in the unlikely event that a rescue mission is necessary during Atlantis' upcoming STS-125 mission to repair NASA's Hubble Space Telescope. The mission is slated to launch October 10 2008.

After Endeavour is cleared from its duty as a rescue spacecraft, it will be moved to Launch Pad 39A for its STS-126 mission to the International Space Station. That flight is targeted for launch Nov. 12 2008."
