NASA's Deep Impact's Tempel 1 Mission Update. Images of impact taken with the medium resolution imager. The blue dotted line is the position of the spectrometer's slit.
This image from NASA's EPOXI mission shows Hartley 2 moving across the background field of stars. The coma, or cloud of gas and dust around the comet, expands and brightens over this time period. Animation available at the Photojournal.
This pair of images shows a before-and-after comparison of the area on comet Tempel 1 targeted by an impactor from NASA's Deep Impact spacecraft in July 2005.
