I rather admired the tribute NASA gave to Eugene Shoemaker. As well as discovering the comet that whacked into Jupiter, he was the great planetary geologist who proved Barringer Crater was actually meteoritic in origin and that the Earth did have a record of large impacts. He was also the pioneer of understanding how and when the Moon's craters formed.
So NASA gave him the send off he deserved, they placed a small portion of his ashes on the Lunar Prospector probe which was crashed into the South Pole of the Moon in the hope of discovering ice. In the process it carved out a new crater.
