More specifically, what parts of it actually broke?<p><hr /></p></p></blockquote><br /><br />Well, think of it this way:<br /><br />An astronaut, strapped safely into his seat in, say, a Soyuz spacecraft, will be mildly uncomfortable and probably pretty wired on adrenalin during ascent, but he'll be perfectly fine. Push him off a ten-foot-high walkway, and he could get bruised, break bones, dislocate joints, get a concussion, or even die, depending on how he lands.<br /><br />Basically, ascent is a very controlled situation. The fall was completely uncontrolled, and the vehicle wasn't encapsulated in a payload fairing that would've kept protruding bits from being smashed.<br /><br />However, the bulk of the cost is probably not replacement parts. The bulk of the cost will be the manhours needed to test and recertify the spacecraft and ensure that they've found and repaired everything that was damaged. Any prior testing will probably have been invalidated by the accident, so they're pretty much stuck redoing all of their flight testing, because it's the only way to be sure the vehicle is okay now.<br /><br />I'm working on a space project right now, and several times managers have e-mailed out to the entire team that picture of the weather satellite lying on its side to remind us of the importance of procedures. The moral of the story is <i>never take shortcuts</i>. That includes making sure that the checklist isn't lying, and it includes not borrowing parts without asking and without documenting the fact. The team that tipped the satellite was actually supposed to verify that it was properly bolted down, and not just by looking at the checklist. They skipped the step. And the team that borrowed the bolts was supposed to document the fact. They didn't.
