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: Deep Impact's primary mission was to deliver a special impactor spacecraft into the path of comet Tempel 1. After its successful impact mission, Deep impact was sent on an extended mission of another comet flyby, observations around planets orbiting other stars and a space-based observatory to study targets of opportunity with its telescopes and instruments.

Accomplishments: Making a video of Earth from so far away helps the search for other life-bearing planets in the Universe by giving insights into how a distant, Earth-like alien world would appear to us. For example, Sun glints off Earth's oceans could guide scientists to spot alien oceans (and potentially habitable alien worlds).

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.
