3.Q: Following the Columbia accident a couple of years ago, what has NASA Ames done to tests heat shield materials that may aid in returning the Space Shuttle to flight?
Fretter: "Ah, we've been involved in supporting the Johnson Space Center in testing various repair kits, ah, repair ideas for – principally for the ah the carbon-carbon, or, the RCC section. The one that actually failed was a chunk of the foam from the external tank hit the wing leading edge section, which is made out of a carbon-carbon material, that is woven carbon material, which is coated with an oxidation resistance so you can reuse this material over and over and over again. And it hit with such force that it actually caused a big hole, and the hot gases got in there. So, what we're looking at right now is repair kits if they go out into space and see—before they come back they're going to be inspecting the whole – umm – control surfaces and important sections like the nose and wing leading edges to see is there another hole there. And if there is, how to repair that hole. . . . (57 SECONDS)
