LCROSS will begin its trip to the moon on the same rocket as the Lunar Reconnaissance Orbiter (LRO), which will conduct a different lunar task. Launch is scheduled for no earlier than June 17th, 2009 on an Atlas V rocket from Kennedy Space Center, Florida.

Since the two STEREO spacecraft went into orbit around the Sun at the beginning of 2007, they have been slowly drifting apart from Earth, and from each other. After two years in solar orbit, the two spacecraft have finally reached quadrature.

But last week, Australian comet-hunter Alan Watson helped us with yet another historic achievement -- the recovery of a comet! Here's how it unfolded.
