Space exploration doesn’t always go smoothly. For instance, the triumph of Apollo 11 was followed by the failed mission and near-disaster of Apollo 13. Prior to launching Alan Shepard into space in 1961, NASA blew countless space rockets to pieces on the launchpad. Russia still crashes its spaceships periodically. And lest last week’s euphoria over the Mars rover Curiosity landing have you thinking NASA’s got this spaceflight thing down to a pure science, please see the video below. Late last week, NASA’s experimental unmanned Morpheus lander failed spectacularly during vehicle tests. Really spectacularly. With fire and explosions and whatnot.
