NASA Rushes To Find Landing Site For Upcoming Mars Probe

Finding a place to park in the city -- or, a crowded airport ramp -- is an issue nearly all of us have experienced at one time or another. It's also a problem for scientists at NASA who are rushing to find an alternative landing site for an upcoming Mars probe.

The Associated Press reports images taken by the Mars Reconnaissance Orbiter of the planned landing site for the space agency's Phoenix Mars lander showed an unwelcome surprise: large, bus-sized boulders all over the place. Not the most hospitable environment for a $400 million space probe.
