At 0552 UTC two years ago today (still July 3rd in the western U.S.), NASA's Deep Impact mission struck 9P/Tempel 1. The flyby spacecraft's high-res camera took this photo 67 seconds after the impactor spacecraft hit the comet's nucleus. The flyby spacecraft is still alive and well, and yesterday was given a new comet mission. See news below. Image credit: NASA/JPL-Caltech/UMD.
