Deep Impact's impactor spacecraft is scheduled to collide with Tempel 1 at10:52 p.m. Pacific time on July 3 (1:52 a.m. Eastern time, July 4). The mission's flyby spacecraft will use its infrared spectrometer to sample the ejected material, providing the first look at the chemical composition of a comet's nucleus.
These data were acquired from June 20 to 21, 2005. The picture of Tempel 1 was taken by the flyby spacecraft's medium-resolution instrument camera. The infrared spectrometer uses the same telescope as the high-resolution instrument camera.
