In this image released by NASA/Jet Propulsion Laboratory, the Tempel 1 comet is shown after the impactor probe from the Deep Impact spacecraft collided with the comet early Monday, July 4, 2005. The successful strike 83 million miles away from Earth occurred just before 11 p.m. PDT, according to mission control at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., which is managing the $333 million mission.
