Comet Redux

Yesterday NASA’s Stardust mission flew by comet Tempel 1 and took detailed photographs. In July 2005, the same spacecraft (then named Deep Impact) watched as a special impactor successfully slammed into Tempel 1. Investigators have located the 2005 impact zone on the comet and can see a crater that wasn’t there before.

This is the not the only super-duper cool astronomy stuff that’s happening right now. In just 28 days, the Messenger probe will become the first spacecraft ever to go into orbit around the planet Mercury.

Should humans build robots? You bet. Where should we use them? Outer space!
