The KSC debris reconstruction team identified pieces as to location on the orbiter, and determined damaged areas.Ībout 38 percent of the orbiter Columbia was eventually recovered.Īs a research mission, the crew was kept busy 24 hours a day performing various chores involved with science experiments.Įxperiments in the SPACEHAB RDM included nine commercial payloads involving 21separate investigations, four payloads for the European Space Agency with 14 investigations, one payload/investigation for ISS Risk Mitigation and 18 payloads supporting 23 investigations for NASA’s Office of Biological and Physical Research (OBPR). Nearly 85,000 pieces of orbiter debris were shipped to KSC and housed in the Columbia Debris Hangar near the Shuttle Landing Facility. The search was headquartered at Barksdale Air Force Base in Shreveport, La. “This day has brought terrible news and great sadness to our country … The Columbia is lost there are no survivors… The cause in which they died will continue… Our journey into space will go on.A seven-month investigation followed, including a four month search across Texas to recover debris. Nobody was permitted to enter or leave the room, and flight controllers had to preserve all the mission data for later investigation. Two minutes later, Mission Control put contingency procedures into effect. He called on the Ground Controller to “lock the doors”. The crew, if not already dead, were killed no later than this point.ĩ:05am – Residents of north central Texas, particularly near Tyler, reported a loud boom, a small concussion wave, smoke trails and debris in the clear skies above the counties east of Dallas.ĩ:12 am – After hearing of reports of the shuttle being seen to break apart, Entry Flight Director LeRoy Cain declared a contingency (events leading to loss of the vehicle) and alerted search-and-rescue teams in the debris area. The crew module remained mostly intact through the breakup, though it had lost enough structural integrity that it lost pressure, and was completely depressurized no later than 9:00:53.ĩ:01am – The crew module, intact to this point, was seen breaking into small subcomponents. Before the orbiter broke up at 9:00:18, the Columbia cabin pressure was nominal and the crew was capable of conscious actions. In Mission Control, while the loss of signal was a cause for concern, there was no sign of any serious problem. At that time, the Master Alarm would have sounded for the loss of hydraulics, and the shuttle began to lose control, beginning to roll and yaw uncontrollably, and the crew would have become aware of the serious problem.ĩ:00 am – Videos and eyewitness reports by observers on the ground in and near Dallas indicated that the Orbiter had disintegrated overhead, continued to break up into more and smaller pieces, and left multiple contrails, as it continued eastward. ![]() ![]() Bolden, NASA official.Ĩ:59 am – A broken response from the mission commander was recorded: “Roger, uh, bu – …” It was the last communication from the crew and the last telemetry signal received in Mission Control.Ĩ:59 am – Hydraulic pressure, which is required to move the flight control surfaces, was lost at about 8:59:37. And, to find after Columbia that it was fractions of an inch thick, and that it wasn’t as strong as the Fiberglas on your Corvette, that was an eye-opener, and I think for all of us … the best minds that I know of, in and outside of NASA, never envisioned that as a failure mode.” – Charles F. “Never did we talk about because we all thought that it was impenetrable … I spent fourteen years in the space program flying, thinking that I had this huge mass that was about five or six inches thick on the leading edge of the wing. Bolden, who worked on tile-damage scenarios and repair methods early in his astronaut career, said in 2004… Don’t you think it would be better for them to have a happy successful flight and die unexpectedly during entry than to stay on orbit, knowing that there was nothing to be done, until the air ran out?” -Wayne Hale, NASA Officialīefore the flight NASA believed that the RCC (reinforced Carbon Carbon leading edge panels) was very durable. If it has been damaged it’s probably better not to know. “You know, there is nothing we can do about damage to the Thermal Protection System. In 2013, retired NASA official Wayne Hale recalled what Director of Mission Operations John Harpold told him before Columbia’s destruction… High resolution film taken during lift-off of STS-107 was reviewed overnight and confirmed foam debris striking the left wing, potentially damaging the thermal protection on the Space Shuttle.
