The EPOXI mission is the combination of two independently proposed scientific investigations using the flyby spacecraft of Deep Impact in an extended mission:
- EPOCh (Extrasolar Planet Observation and Characterization) utilized the HRI Visible CCD on the Deep Impact flyby spacecraft from January through August 2008 to observe transits of known extrasolar planetary systems (GJ 436, HAT-P 4, HAT-P 7, TRES-2, TRES-3, WASP-3, XO-2, and XO-3) to look for perturbations due to terrestrial planets in low-order resonances and search those same systems for secondary occultations of the hot Jupiter by the star. In October 2009 EPOCh used the HRI Visible CCD to image the transiting exoplanet microlensing target MOA-2009-BLG-266. EPOCh also utilized the HRI Visible CCD and the HRI Infrared Spectrometer to characterize Earth (2008 and 2009) and Mars (2009 only) as analogs for extrasolar planets.
- DIXI (Deep Impact eXtended Investigation) consisted of a flyby of 103P/Hartley 2 at a closest approach distance of 700 km on 4 November 2010 in order to study a second short-period comet with the same set of instrumentation as was used at 9P/Tempel 1.
The SBN is the lead PDS node to archive the EPOXI mission data. The EPOXI project also delivered the PDS-formatted EPOCh data to the Multi-Mission Archive at the STScI (MAST).
