we would like to say that there were other alternatives...the truth is, with what was known and what could be actually be done...there wasn't much anyone could really do. The flight was not equipped for space walks...as much as people sit here and think "well, they should have done one regardless" its a far harder task than just jumping into a suit and going out the door. AFAIK almost all of the flights where space walks were done the robotic arm was utilized to hold onto the astronaut...and that same arm was not part of the shuttle bay equipment this time around. The only "non-arm" space walks that I know of ( one I know of for sure, maybe two or three??? ) were test runs of new "walk-packs" and they were not on the shuttle either. Not to mention, none of the crew were trained for space walks. Then there was the fact that there is no tile repair kit as part of the shuttle inventory. They had one for a while, but stopped taking it up because of the fact that they came to the conclusion that tile repair in space was not feasible in most circumstances...since there are 24k tiles to choose from and being able to modify them in space would mean extra tools and training. And as for going to the space station...the different altitudes and orbits seem to have ruled that out. The Shuttles have only so much fuel for their thrusters...and its orbit is usually designated by what course it takes after lift-off, since it utilizes the thrust from that to obtain its position. Once in orbit, the shuttle is pretty much limited to using its thrusters to maintain altitude and trim within in narrow window of space. So, let's say you have a go at all these options anyway...ok they space walk, they find the damage...they even somehow manage to change their orbit and direction...and make it to the space station. Now what? Seven extra people are now in a craft that isn't ready to have 10 people in it yet. Voriax is correct about the Russian Buran, it is sitting in some yard in Russia wasting away...having never flown after its maiden voyage. The escape pod on the station is a three man capsule...and what do you do if you use that and the station has an emergency? It would be a couple months at best before another flight from either Russia or NASA could get another one up there...plus more supplies. Then there are the other Station Issues....like, could the scrubbers currently on board be able to support the extra CO2?...and just what was the supply situation?...and what would be sent up on the next rocket or shuttle...another pod, food or other things, like repair supplies? After all, a rescue mission would not be ready over night...even at a rushed pace, that would only endanger that ship and crew as well. As for the supply rocket that went up...it was already packed and ready to go....and it's cargo couldn't be modified on the pad. It isn't like packing up the SUV...you can't just go to the driveway, open up the door and throw in some more sh*t folks. It's a complex matter to get something ready to go into space. In reality....the only thing that could have possibly saved them was if NASA or the Russians had an "emergency rocket" on the pad each time a shuttle launch was performed...and sadly neither agency has the money for that. It's all a matter of would of, could of, should of at this point. It's not an excuse to say "oh well, sh*t happens...they did what they could" nor is it to say that NASA shouldn't be held accountable for some of it's decisions or policies....it's somehting that the agency will need to learn from. It found out that what worked on 50 other missions, didn't on this one and rule/guidebook must now be re-vamped. New policies and what if strategies will have to be created...and the way they evaluate shuttle damage at the time of lift off will have to be re-thought. However, we all need to remember that despite all we know...and all we try to figure out ahead of time...there are still going to be those times when only our failures present us with new knowledge and insight. I know that seems kind of cold...but its a truth none the less. Nothing new in the history of mankind was ever bought without the blood of some of those brave few who ventured out at the vanguard. Everyone one of us would love to see every astronaut go up and come back unharmed...but the truth of the matter is, that won't always be the case. To expect a "zero loss" rate is unrealistic...and if that is the case, then we should just forgo space exploration...because manned space flight is always going to entail risks. There will be future tragedies despite all we do. If we are continue to venture into space...then we must be prepared for the fact that among our victories, their will be losses.
