Space Shuttle Damaged After Lift-Off
Updated 2:47 PM EDT, Tue, 12, 20 May09
The space shuttle Atlantis suffered damage to the exterior two minutes after take-off.
Astronauts discovered a 21-inch stretch of nicks over four or give of thermal times on the right side of Atlantis.
As I said, you don’t seem to understand how these things work”
No I will tell you what is not going to work your covert insults.
You are not getting it here, If you had a failure and follow the same Exact procedure again guess what?
Look from what I have seen there seems to be no predictability I assume some bond-line testing in the area adjacent to the shuttle is being done and some type of a light scrim reinforcement is in the final spray-up BTW just why is this experimental? and Assurances can be; Done as well as humanly possible with the best material available and double checked.Plus nothing goes out the door I personally would not ride in..Things like that.
Sorry for the jibes. Sincerely. I know it doesn’t help.
What I am trying to say is the following:
1. You MUST understand that this is an EXPERIMENTAL system, and NO part of it will have 100% assurance of success. Nothing made by man will possess such an outlandish requirement.
2. The materials are a fixed condition, and faced with not flying because the proper material is locked out from you or flying in the recognition of a persistent risk, the choice should be obvious.
3. Based on the conditions imposed by point #2, it is the policy of NASA to mitigate insofar as possible the risks by conducting post-flight forensics and continuing analysis and hardware adjustment. In truth, they could have followed this strategy a Loooooong time ago and we would likely still have Columbia. For that, NASA deserves certain scorn.
Experimental Flight Test is a very dangerous endeavor at times, the flight crews accept the risks involved, and the technicians and engineers do whatever they can to reduce danger. But there are limits, which give rise to strategies of mitigation of the effects of those risks.
To bring it all the way back around to current events, the foam strikes post-Columbia are smaller, less frequent, and known. The system has improved, but the management of the system could have learned the lesson without losing seven fine men and women.
The defects in the STS design are being driven out as much as possible in Orion, with the specific problems of foam shed being a biggie. The foam is alway behind and away from the Orion crew vehicle, so no contact is really available.

No Problem I was not questioning the Shuttle in it's complexity was instead probing at the foam which has caused problems and loss of life in the past.now has sort of reared its head again.
8:00 CT spacewalk has begun
