Deep Impact and Stardust: Still on assignment

Two old NASA missions have new lives. The agency’s Deep Impact mission, which 2 years ago fired a projectile into Comet Tempel 1 and imaged the debris from the explosion, will now journey to Comet Boethin.

NEW JOURNEY. The Stardust mission, which collected material from Comet Wild 2 in 2004, is now scheduled to visit Comet Tempel 1 in 2011.
