NASA returns to comet it attacked (photos)

It's about 587 trillion miles away but NASA has managed to visit comet Tempel 1 not once - but twice within the past six years. You may recall that Tempel 1 was first visited on July 4, 2005 when the spacecraft Deep Impact sent a probe that exploded on its surface

Now, Stardust NExT sped within 112 miles of the comet to see what changes, if any, the explosion made to its surface.  This photo was taken on Feb. 14, 2011 at 8:39 p.m. PST and received on Feb. 15, 2011.
