NASA orders Discovery to delay landing
A torn thermal blanket under a cockpit window, most likely ripped by launch debris, was judged good enough for re-entry and left alone.
"But I would tell you, I think as most of us would tell you, that I'd rather have more data because it makes me better prepared," he said. "I don't think, honestly, that it can add to my anxiety or list of things that I'll worry about or not worry about. The buffers pretty much fall either way." Never before have astronauts or flight controllers known so much about the condition of a returning shuttle. "That's a fantastic step forward," astronaut Stephen Robinson said from orbit Sunday. "The next step is to be able to repair any damage we happen to have found. Our shuttle didn't require any repair, just a tiny little dental flossing of plucking a couple of gap fillers out." Robinson did the flossing during a spacewalk last Wednesday, easily pulling away two strips of thermal tile filler dangling from Discovery's belly. NASA feared the hanging material might lead to a repeat of the Columbia catastrophe and ordered the first-ever orbital repair to a shuttle's heat shield. Collins' co-pilot, James Kelly, said he did not have any concerns about re-entry and noted that all the prelanding flight control checks went well. "I guess you almost have to thank the Columbia crew," Kelly said. "The sacrifices they made allowed us to get a lot smarter about it, get a lot of tools on board that we could use to look at the vehicle." Like other NASA officials, Cain stressed that Discovery looked "entirely clean" for the plunge from space. Nonetheless, he expected to have butterflies in his stomach, just as he's had every other time he's entered Mission Control to direct a shuttle launch or landing. If he didn't have butterflies, "I'd probably turn right around and go back outside and find somebody else to do the job." Cain was in the same flight director's seat for Columbia's re-entry on Feb. 1, 2003. "There are a lot of things to think about. There are a lot of things to worry about," he said. "That's what I get paid to do is to worry �� and I do it a lot."
