NASA's Deep Impact Spacecraft Eyes Comet ISON
Pasadena CA (JPL) Feb 07, 2013
NASA's Deep Impact spacecraft has acquired its first images of comet C/2012 S1 (ISON). The images were taken by the spacecraft's Medium-Resolution Imager over a 36-hour period on Jan. 17 and 18, 2013, from a distance of 493 million miles (793 million kilometers). Many scientists anticipate a bright future for comet ISON; the spaceborne conglomeration of dust and ice may put on quite a show as it passes through the inner solar system this fall. "This is the fourth comet on which we have perfo ... read more
