comet tempel 1

November 4, 2010 will forever be noted in the history textbooks of the country as the day a spacecraft approached the comet Hartley 2 within a distance of 700 km.

Experts of the US Aerospace Agency were confused after a ship suddenly stopped contacting the control center.

The first close-up shots of comets Hartley 2 sent by Deep Impact spacecraft show that this comet is shaped like a giant peanut.
