Views of Hartley 2 Nucleus and Inner Coma

January 11, 2013
The Medium-Resolution Instrument on NASA's EPOXI mission spacecraft obtained these views of the icy particle cloud around comet Hartley 2. The image on the left is the full image of comet Hartley 2 for context, and the image on the right was enlarged and cropped. The images confirm that the particles seen in the High-Resolution Instrument images are real and not artifacts. This image was obtained on Nov. 4, 2010, the day the EPOXI mission spacecraft made its closest approach to the comet. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the EPOXI mission for NASA's Science Mission Directorate, Washington. The University of Maryland, College Park, is home to the mission's principal investigator, Michael A'Hearn. The spacecraft was built for NASA by Ball Aerospace & Technologies Corp., Boulder, Colo.
