EPOXI is a combination of the names for the two extended mission components: a search for extrasolar planets during the cruise to Hartley 2, called Extrasolar Planet Observation and Characterization (EPOCh), and the flyby of comet Hartley 2, called the Deep Impact Extended Investigation (DIXI).
By looking back at the spectrum of Earth from tens of millions of kilometers away, EPOXI has been used to practice techniques for detecting oceans on extrasolar planets.
An international team of scientists that includes Lucy McFadden of NASA's Goddard Space Flight Center in Greenbelt, Md, discovered the comet on November 4, 2010 through the EPOXI mission spacecraft.
addition to Rosetta and EPOXI, Stardust, Dawn, Messenger, and New Horizons continue toward targets they will reach within the next five years.
The researchers observed Hartley-2 six times during the summer, fall and winter of 2010, both before and after the EPOXI mission's Deep Impact spacecraft had its November rendezvous with the comet.
Interestingly, it is the target for a flyby by the Deep Impact probe in November, as part of the EPOXI mission (Extrasolar Planet Observation and Deep Impact Extended Investigation).
Now, in an extended mission named EPOXI, it's on its way to meet Comet Hartley 2 in 2010.
These findings, as well as information gleaned from a recent NASA EPOXI spacecraft flyby of Comet 103P/Hartley 2, are expected to offer new insights as researchers strive to better understand comets and the role they could possibly play in aiding human solar system exploration, said Nalin H.
NASA has renamed the mission EPOXI, condensed from "Extrasolar Planet Observations and Characterization" and "Deep Impact eXtended Investigation.
Washington, June 26 (ANI): NASA's historic Deep Impact spacecraft, which is on its current University of Maryland-led EPOXI mission, will fly past Earth for the fifth and last time on Sunday, June 27th.
Deming is the deputy principal investigator who leads the team that works on the Extrasolar Planet Observations and Characterization (EPOCh) part of Deep Impact's extended mission, called EPOXI.
In November 2008, NASA test-drove the network by sending space images to and from the EPOXI spacecraft, some 20 million miles (32 million kilometers) from Earth.
