Deep Impact probe 3 flybys

The Deep Impact probe made the first of three flybys designed to use the planet's gravity to hurtle the spacecraft toward comet Hartley 2 for a 2010 meeting.

NASA initially wanted Deep Impact's second act to be an exploration of comet 85P/Boethin in 2008. But to scientists' surprise, a bevy of ground and space telescopes were unable to spot it this fall. Astronomers believe the comet may have shattered into specks too small to be seen from Earth.
