^* Up until Obama’s first NASA budget appeared, in February 2010, the moon base was slated to be built sometime in the 2020s. That program (Constellation) has been cut, and now we’re headed to a near-Earth asteroid and on to Mars. Then again, Congress has yet to approve the budget plan, so it’s hard to know for sure, at the time of this writing, just where we’ll end up hauling our rovers next.
