Deep Impact's final observations: Comet ISON This image of comet ISON is a stack of 96 photos taken with Deep Impact's Medium Resolution Imager on March 9 and 10, 2013. The image is enlarged from the original resolution by a factor of 4. The comet was about 3.9 AU from Deep Impact at the time. These are the last images that Deep Impact returned to Earth before failing in August 2013. NASA / JPL / UMD / Emily Lakdawalla
