The Rescue Plan That Could Have Saved Space Shuttle Columbia 247

Posted by Soulskill from the if-only dept.
An anonymous reader writes "In February, 2003, space shuttle Columbia was lost upon atmospheric re-entry. Afterward, NASA commissioned an exhaustive investigation to figure out what happened, and how it could be prevented in the future. However, they also figured out exactly what would have been required for a repair and rescue mission using Atlantis. Lee Hutchinson at Ars Technica went through the report and wrote a lengthy article explaining what such a mission would look like. In short: risky and terribly complex — but possible. 'In order to push Atlantis through processing in time, a number of standard checks would have to be abandoned. The expedited OPF processing would get Atlantis into the Vehicle Assembly Building in just six days, and the 24/7 prep work would then shave an additional day off the amount of time it takes to get Atlantis mated to its external tank and boosters. After only four days in the Vehicle Assembly Building, one of the two Crawler-Transporters would haul Atlantis out to Launch Complex 39, where it would stage on either Pad A or Pad B on Flight Day 15—January 30. ... Once on the pad, the final push to launch would begin. There would be no practice countdown for the astronauts chosen to fly the mission, nor would there be extra fuel leak tests. Prior to this launch, the shortest time a shuttle had spent on the launch pad was 14 days; the pad crews closing out Atlantis would have only 11 days to get it ready to fly.'"

      The foam strike was not observed live. Only after the shuttle was orbiting Earth did NASA's launch imagery review reveal that the wing had been hit. Foam strikes during launch were not uncommon events, and shuttle program managers elected not to take on-orbit images of Columbia to visually assess any potential damage.

        If you knew with complete assurance that the first crew would be lost if they attempted to land without repair, then it would likely be worth the risk to a second crew to mount a rescue.

        If on the other hand, there’s only some chance that the first crew would be lost attempting to land, then working that risk into the risk to the second crew is reasonable. IE if there’s a 10% chance that there might have been trouble landing (and it sounds like the foam strikes leading up to Columbia’s trouble were in fact common, so could be considered low-risk) then it’s not unreasonable to decide that the risk of the second crew is an unreasonable risk. Consider also that the risk to this second crew for an accelerated launch process would likely have been FAR greater than a “normal” shuttle launch (assuming it can be said there’s anything “normal” about strapping a bomb to your ass and fleeing the planet...)

        If there’s a very high chance of failure of the original crew’s landing, then the additional risk might be worth it. If not, then you really are doubling down and risking losing two crews. It’s entirely plausible that due to the corners cut for an accelerated launch Atlantis could have exploded during launch, leaving Columbia to still take their chances landing with a damaged wing.

        Armchair quarterbacking is easy. Saying they should have risked a second crew *now*, knowing that it’s an impossibility and that your assertion that the risk is reasonable will never be tested is also easy. Being left to make that call in the moment, knowing that you could be sending a second shuttle crew to their deaths trying to help another crew that might not even need the help the first place. Little bit harder to live with that one...

        The loss of the Columbia crew is a tragedy, but looking back based on this report, it doesn’t seem like the way it was handled was unreasonable.

      • Ah, the fine folks who don't read TFA. No, you could not have moved the Columbia to the ISS - it would have taken approximately twice as much fuel as the shuttle carried to pull than maneuver off.

    • The tiles on the leading edge of the wing aren't foam, they are a ceramic material and each tile is designed for a specific location on the wing. Cover the hole up? Not likely with the materials they had. It's not like they have extra leading edge tiles laying around anyway. The only real option would be to get them on another shuttle since the ISS was not accessible.

    "Could" is a pretty strong word. As Lee goes into some depth on exactly how much of a record breaking effort it would have taken just to get Atlantis off the ground in time to save Columbia, and how many corners would have to be not only cut but removed with a chainsaw, it would be more accurate to say that the plan proposed by the CAIB shows that even if the Launch Director had pointed to Columbia as it was launching and said "Hey, there are some missing tiles there. We need to get Atlantis ready right now", they still wouldn't have been able to do it.

    The thing to take away from this is not that NASA could have saved Columbia but didn't, but that they changed the plan for every other shuttle launch so that they would always have a second launch vehicle on standby. It's about learning from mistakes, not making them worse.
