One of the first amazing images of NASA's EPOXI mission flying by comet Hartley 2 at minimum distance of about 700 km (435 miles). The encounter took place at about 11 millions miles distance to earth.
Detail of the comet showing jets of gas heated by the sun.
Watch the happy people at the mission's control at the Jet Propulsion Laboratory. Closest contact in this video happens at about 01:35:00. Congratulations to mission control!
