But by staying vigilant, we significantly reduce the likelihood of them, and should they happen, we're more prepared for them." I would be very cautious to say that accidents are a thing of the past. "And if we always have in our mind that the next accident is out there, and we're ever vigilant, we do our best to prevent it. "If we do assume are preventable, we're fooling ourselves," Gohmert said. "It's especially heartfelt for those of us who worked with the crew," Gohmert told .Īnd the insights gained the hard way, through understanding what happened to Columbia and the other destroyed spacecraft, have made flying to space safer than it used to be, experts say. Gohmert was part of the team that helped the Columbia crew suit up and prepare on launch day. "We have a poster here in our conference room every day we sit in, with on it, with a sign that says, 'Never forget,' and that's kind of our goal," said Dustin Gohmert, NASA crew survival engineering team lead at Johnson Space Center in Houston. However, accidents like the one that befell Columbia have had an indelible effect on the way NASA goes about trying to keep its astronauts safe. That's the physics of getting off the surface of Earth and re-entering through the atmosphere - we're not going to make that go away." All these liquid and solid propellants are very high-energy, and managing all that energy during ascent and landing is not going to change. "But you're talking about a very high-energy event. "We always hope and work and strive to avoid ," said Julie Kramer White, chief engineer for NASA's next-generation space capsule, Orion.
