Deep Impact Probe; Sounds Dirrty

NASA spacecraft prob, The Deep Impact, rocketed past Earth on Monday about 10,000 miles over Australia. The Deep Impact is on its way to make contact with another comet.
In 2005, Deep Impact became the first spacecraft to break open a comet by releasing a copper impactor into its core and scientist were able to get a first hand look at its interior.
Now on its second mission, called Epoxi, the probe is set to meet Hartley 2 in 2010 about 12 million miles from Earth.
But first, "We're taking laps around the sun until the comet comes," said William Blume of NASA's Jet Propulsion Laboratory. Source.
