<font color="yellow">"so what *did* happen to that craft? "</font><br /><br />It was cut (in part) due to budgetary woes. There's never enough money for everything. With the shuttle and the ISS both continually over-budget, and essentially uncancellable -- other items in the manned spaceflight program fall victim to the axe.<br /><br />However, it also had a problem diametrically opposed to that of the shuttle. Whereas the shuttle was designed to be all things to all people, the X-38 was largely designed as a one-trick pony -- return six people from the ISS in the event of an emergency. Mind you there were a few storyboards around on possible extensions, but it was really a low-budget project and focused on that one goal.<br /><br />Mind you that's a very worthy goal. However, it's not one that was time-critical. Not having a six-person evac from the ISS is *a* reason there aren't six people up there... but it's not <b>the</b> reason. <b>The</b> reason we don't have them up there is because the station doesn't have a need or a place for that many crew. Therefore, with that the primary goal of the X-38, and no particular <b>need</b> for that service for a number of years... even before the Columbia disaster, the X-38 project could safely be axed.
