    The EPOXI Deep Impact comet investigation team, known for its flyby of Comet Tempel 1, was able to re-use its spacecraft to fly near a second comet, Hartley 2. The second flyby was executed in November 2010. The close approach of the spacecraft showed the comet's unusual shape, and jets emerging from various lumps. The images are now being analyzed to glean clues to the formation of Hartley 2.
