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: The main objective of Deep Impact's extended EPOXI mission is to investigate planets known to orbit three to six distant stars and to search for previously undiscovered planets. The spacecraft also will search for evidence of rings and moons associated with the known giant planets of the targeted stars.

Accomplishments: This mission is in progress.

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.
