That was not an answer...merely a possible answer. I know that there are a lot of things that we have done in the past that we can't do today...not without rebuilding an infrastructure we no longer need.
This was the first "science mission" in over two years.
I underdstand your point and it makes sense
Were the small engines set to go off "too late" AND ignoring the force of continuous firing which caused a further misalignment of the ship and making other portions of the ship vulnerable to the heat???
Or was the auto-firing of the small engines at "the most crtical possible point"??
Had to put this in my own dumb terms...hardly a rocket scientist!!!
Rumor is one of the crew emailed someone about the damage they could see.
There were two EVA suits onboard. I have read that there is a disagreement as to whether an EVA could have been performed through the hatch in the tunnel
leading to the SpaceHab. Maybe it could.
You're asking questions. I like that. There are no stupid questions. Well, okay there are "some" stupid questions. I dont' think yours are. The crew had to be able to access the payload bay. The payload bay doors sometimes hava a problem closing. The crew MUST be able to facilitate this function manually if needed. I don't pretend to propose the crew could have inspected the underside of the wing. We are now hearing the leading edge was jagged, and that could have been viewed IMO. I addressed that process a number of responses before this one.
Docking with the ISS is sometimes prevented by non-similar orbits. I'd be surprised if this isn't a problem most of the time. Out of 360 degrees, I'd be surprised if the shuttle were to be within 20 degrees plus or minus most of the time, on non-docking missions. I believe that it may be true that the shuttle seldom achieves an orbit much more than 90 degrees off that of the space station. That being said, non-similar trajectory is still a problem. Then there's the issue of Columbia being too heavy to reach the ISS. I believe that to be the case. But then that could have been a reason to retire it, if it weren't for the problem of non-similar trajectory which would make that problem mute.
I think it's reasonable to mention limiting crew size. I just don't think it's the right idea. Losing 4 vs 7 is a no-win fix in my mind. Fix the problem. Lauch as many crew as you need or want to.
I'm not convinced a high-speed computer could check the film in real time, with enough precision to make a go/no-go decision. I may be wrong. It would detect and highlight certain frames. If those frames were judged by a NASA tech to be a problem, you could no-go space entry. That is an iffy proposition. Even after two weeks the conclusion regarding the problem the insullation actually posed, is still iffy. What you might set up here is a red-tag on each and every mission do to second-guessing. I'd rather see a space retrieval remedy devised.
I'm not as anti-NASA as it sounds on some of these threads. I'm willing to kick them on the hind-side if I think they warrant it. I'm also willing to recognize sucesses when it's warranted. What might be a good idea, is to set up a review board that establishes an oversight of NASA operations. They shouldn't be too tied to the techs or the management. They should be an unbiased liason, that in extreme circumstances could slap down management hard. Floating from one mission specific pre-flight crew to the next, they could develop a relationship with hands on people that would make absolutely sure NASA management wasn't sh-t canning valid complaints and concerns. I do not believe we are at the stage where privatization is viable. I still believe an SSTO space plane is a must before privatization can be realized. BTW, I think that is the single most important task this nation faces, outside of immenent military hostilities and the war on terrorism.
Space is the high ground. We need access on a ho-hum basis. Fly into space, return the same day. Fly into space again. When this happens, the United States will become the Federation. We will inhabit space. We will make sure that a representative Republic rules the high frontier. Commercially, privately, governmentally, militarily, this should be the only acceptable outcome to citizens of the United States.
a standard video camera if using optical + digital zoom can get to 100X magnification. When panning the camera, lateral speed is negated. I said that in the photo, the view is from the rear and the craft is in a down angle configuration, when the cmeraman pulls back it shows the object travelling to the left.....sideays. send me an E-address where I can send you the pics for comparison.
It would not have made any diff, anyway cuz they were screwed. If that did infact happen, I would assume we will never know.

Its all about WILL and GUMPTION. The crew could have been saved if the decision had been made to save them...
No, the form section would have a relatively small delta V ( velocity difference). STS107 at that time was between mach 1.5 and mach 2 (@1500 mph) and the foam that separated is moving at the same speed. It has little mass to do any damge and would accelerate from drag in the slipstream between the tank and the shuttle. In less than 100 feet it may have slowed by 100 mph at point of impact with the shuttle. This would be the same as if the shuttle was on the ground at zero speed and the foam hit with a speed of @50-100mph.
From the photo of the foam break up after impact I would tend to believe the first point of impact was the leading edge and not underwing tiles. Grazing the tiles would not cause the falling tank foam to go to powder but hitting the leading edge first would. It is still unlikely this caused enough damge alone to be the single root cuase of failure but more study is needed.
