Scientists at a NASA briefing held in Washington Nov. 18 discuss the data collected by the EPOXI mission on its recent flyby of comet Hartley 2. Travelling at a speed of 27,000 mph, the spacecraft passed Hartley 2 at an altitude of about 435 miles from the comet's surface, close enough to reveal details of its nucleus and give scientists the most extensive look at a comet in history. Comets are remnants of the formation of our solar system more than 4-and-a-half-billion years old.
