Space Shuttle Columbia is lost

On Saturday Feb. 1, 2003, the Space Shuttle Columbia was lost and seven NASA astronauts perished. They were Rick Husband, Mission Commander; William McCool, Pilot; Michael Anderson, Payload Commander; Kalpana Chawla, Mission Specialist; Laurel Clark, Mission Specialist; David Brown, Mission Specialist and the Israeli astronaut Ilan Ramon, Payload Specialist.

The Orbiter was flying over Texas, about 15 minutes from landing and at about 18 times the speed of sound. It was at an altitude of 63 km, about 1400 km from the landing site at KSC.

Launching Space Shuttle Atlantis on a rescue mission

If NASA had known ahead of time Columbia was going to disintegrate on re-entry, how would they have gotten the astronauts down?

‘There was actually an exercise done to work this out, at the direction of the Columbia Accident Investigation Board (CAIB),’ Andy Burns, Student of Space History and Flight Officer / Aviator at United States Navy (USN), says on Quora.

If NASA had known ahead of time Space Shuttle Columbia was going to disintegrate on re-entry, they could have tried to rescue its crew. Here’s how.

‘While Columbia was on-orbit, Atlantis was undergoing preparations for a March 1 launch as STS-114. The CAIB exercise determined that it would have been possible, albeit a difficult and demanding race against time, to launch Atlantis on a rescue mission.

‘Columbia would have faced a 30-day mission limit, determined by its supply of Lithium Hydroxide scrubbers used to remove CO2 from the cabin atmosphere, and additional limits posed by food, water, and power supplies. Depending on when the decision was made to launch a rescue, Atlantis could have rendezvoused with Columbia as early Mission Day 27 – with the launch prep and flight crews working a brutal 24/7 schedule and no room for error or delays, but it was at least feasible.

Connecting Atlantis and Columbia with an extendable boom

‘In the CAIB’s scenario, Atlantis would have launched with a four-person crew of two pilots, and two mission specialists to conduct the EVAs. Most likely the STS-114 Commander Eileen Collins and Pilot Jim Kelly, would have been assigned, as they were already trained, experienced, and ready to fly. The two Mission Specialists might have been the original crew of Stephen Robinson and Japanese astronaut Soichi Noguchi, but NASA might have subbed in more experienced spacewalkers, given the very short time to train. The CAIB exercise determined a list of seven mission specialists who could have been assigned, but this list hasn’t been published.’

Burns continues;

‘Meanwhile, Columbia’s crew would have powered down the orbiter and adopted a max-conservation routine, essentially staying in their bunks as much as possible to conserve oxygen and minimize CO2.

NASA could have tried to rescue the crew of Space Shuttle Columbia if they had known the spacecraft was going to disintegrate on re-entry. Here’s how.

‘Once Atlantis rendezvoused with Columbia, the two EVA astronauts would have connected the orbiters with an extendable boom. They would transfer two EVA suits to Columbia, meeting two already-suited Columbia astronauts, and helping them transfer to Atlantis. Presumably the two would be Columbia’s pilots, Willie McCool and Rick Husband, who could then spell Collins and Kelly at the controls, who by that point would have been manually station-keeping on Columbia for as long as nine hours.

‘The remaining astronauts would relay the EVA suits back and forth, in a grueling 8–9-hour spacewalk. Finally, the last two crewmen would have set up Columbia for control from Houston. Atlantis would back away and prepare for reentry. Unlike later orbiters, Columbia could not be landed remotely, so she would be set up for deorbit and a final fiery reentry, presumably to Point Nemo in the South Pacific, the most remote spot on earth, and where the majority of controlled deorbitings are targeted.’

Space Shuttle Columbia crew doomed

Burns concludes;

‘A Columbia rescue mission would have been the most monumentally difficult and epic space mission in history, and it would have required absolutely everything going right to bring the crew home safely. But NASA has shown time and again its ability to rise to the occasion and bring its formidable engineering and piloting expertise to bear. Instead, the worst instincts of the agency – to micromanage and engage in wishful thinking instead of clear-eyed analysis – doomed the crew.’
