Deep Impact Comet Impactor

description: The impactor is designed to fly itself to a sunlit portion of the comet visible from the flyby spacecraft and Earth's ground-based telescopes. Once there, the comet will actually collide with the impactor at over 10 km/sec (>23,000 mph/hr). We expect a crater ranging in size from a house to a football stadium, two to seven stories deep. The impactor weighs 370 kg (about 820 lbs) and is 1 meter (3 1/2 ft.) in diameter by 0.8 meters (2 3/4 ft) tall. The forward section (bottom) is a series of honey-combed copper plates forming a dome shape that is designed to make the density of the impactor match the anticipated density of the comet, thus opening up a large crater. The back section contains the battery, electronics, computers, propulsion equipment and steering instruments that guide the spacecraft to the comet. The picture shows an "x-ray" view of the impactor with the outer walls displayed as transparent showing the internal components listed above.
