Stardust Mission Makes First-Ever Return To Comet 47
RedEaredSlider writes "NASA's Stardust probe made its closest approach to comet Tempel-1 on Monday night, marking the first time a comet has ever been revisited by a spacecraft. The mission, formally called Stardust-NeXT, for New EXploration of Tempel-1, was launched on its way in 2006. On Monday night it came within 181 kilometers (112 miles) of the comet, taking pictures and measuring the amount and composition of dust in the comet's coma, the plume of gas that surrounds it. It approached the comet at about 10.6 kilometers (6.7 miles) per second, making it one of the fastest probes that has yet flown. Stardust made its closest approach at 11:39 p.m. Eastern and after that, swung around its high-gain antenna towards Earth to transmit its data. The comet and spacecraft are about 336 million kilometers (209 million miles) away, so signals take a full 18 minutes to get to Earth."

Not as cool as landing on it though (Score:2, Interesting)
I used to work at a small robotics company in NYC, that worked on NASA projects. We were building a drilling device that would be part of a lander that was supposed to go to Tempel 1. But NASA/JPL scrapped it in favor of Deep Impact (smashing into the comet instead of landing on it).
So instead of having a spacecraft land on the comet, drill 1 meter into it, take a sample and return the sample to Earth (yes it was ambitious), they opted for smashing into it with Deep Impact and fly bys/dust collection with Stardust.
I'm not really bitter, really. It was fun/cool working there, but I was disappointed that NASA switched things up on us.
