Deep Impact: Comet gets what's coming to it

Vanessa sez: "The Jet Propulsion Laboratory has decided to get back at those nasty comets for all the times they slammed into the Earth. In 2005, JPL will crash a 770-lb. payload into the comet Tempel 1, supposedly in order to get the first-ever look at the inside of a comet. The impact will be visible from Earth.
Hey comet, do you like apples? We're going to take a football-field-sized crater out of your core, how do you like them apples?" Link Discuss
