I know it's rhetorical, but we won't know till wheel stop on STS-114.<br /><br />If we have to wait till September, we have to wait till September. So long as it's done right.<br /><br />Every engineer I've spoken to have said the same thing "Once we get Discovery up, watch the rest of the missions fly out."<br /><br />Even if you can't stand the Shuttle, and I know there's a fair few on this site, we at the very least owe it to Commander Husband, Pilot McCool and their crew...and to Columbia as well.<br /><br />And yeah, I know that's more passion based than anything technical and financially evaluated, but that's the Space Shuttle. It's like what Apollo/Saturn 5 was to the last generation, it's hopefully what the CEV will be to the next generation.<br /><br />Manned Space Flight - it's a risky, expensive business, but you can bet there's some kid in some bedroom in the US that is getting more inspired to aim for a career in space flight from watching a Shuttle launch, more than watching say an Atlas-based mission - and who knows if he'll end up making it safer, faster, cheaper?<br /><br />If things go wrong, learn from it and come back stronger.
