Deep Impact (EPOXI) Mission to Earth's Moon Deep Impact (EPOXI) Mission to Earth Deep Impact (EPOXI) Mission to Beyond Our Solar System Deep Impact (EPOXI) Mission to Comets

Goals: While en route to its second comet encounter, the Deep Impact-EPOXI spacecraft's instruments were used to provide another lunar science perspective.

Accomplishments: Lunar data gathered by Deep Impact during its extended EPOXI confirmed Chandrayaan-1's discovery of water molecules on the Moon. Deep Impact observations revealed that the entire lunar surface is hydrated during at least some portions of the lunar day Data from NASA's Cassini mission also helped confirm the important discovery.

Fast Facts
Deep Impact Facts Deep Impact was the first mission to eject material from a comet's surface.

It is a coincidence that Deep Impact shares its name with a 1998 science fiction disaster film about a comet.

Author Arthur C. Clarke suggested the idea of impacting a comet in his novel 2001: A Space Odyssey

Deep Impact's small probe was the first manmade object to collide with a comet (right).

EPOXI has double meaning. EPO stands for EPOCh the Extrasolar Planet Observation and Characterization phase of mission. XI is short for the spacecraft's extended investigation of comets.

EPOXI is an entirely new mission for a spacecraft already in orbit around our sun.
