NASA’s Deep Impact probe, already a veteran explorer of comets, turns its camera eye toward Comet ISON, a recently-discovered comet expected to put on a spectacular show even to the naked eye in late 2013. Originally launched in 1995 to study Comet Tempel 1 at close range, Deep Impact has since used its cameras to study other comets passing through the solar system. The distance between Deep Impact and Comet ISON at the time the 36-hour photo sequence is taken is roughly 493 million miles.
