Deep Impact +7
"Data from Deep Impact's instruments indicate an immense cloud of fine powdery material was released when the probe slammed into the nucleus of Comet Tempel 1 at about 10 kilometers per second (or 23,000 miles per hour)...
"'The major surprise was the opacity of the plume the impactor created and the light it gave off,' said Deep Impact Principal Investigator Dr. Michael A'Hearn of the University of Maryland, College Park. 'That suggests the dust excavated from the comet's surface was extremely fine, more like talcum powder than beach sand. And the surface is definitely not what most people think of when they think of comets -- an ice cube.'"
