Ball Aerospace's Deep Impact Spacecraft Headed to Comet Hartley 2
December 14, 2007
BOULDER, Colo., Dec. 14, 2007 – The flyby spacecraft built for the successful Deep Impact Mission by Ball Aerospace & Technologies Corp. has been funded by NASA to embark on a new mission to encounter comet Hartley 2 on October 11, 2010.
The Deep Impact Extended Investigation (DIXI), and the Extrasolar Planet Observations and Characterization (EPOCh), together known as the EPOXI mission, will support two goals: the DIXI mission will send the flyby spacecraft to investigate the surface of comet Hartley 2; and while en route, the EPOCH mission will engage the larger of the spacecraft’s two telescopes to search for small planets around stars with already discovered large planets.
Deep Impact accomplished its first successful mission on July 4, 2005, when the flyby spacecraft released its impactor spacecraft to create the historic encounter with Comet Tempel 1. The flyby spacecraft then skillfully maneuvered away from the comet's debris and has since been orbiting around the sun, awaiting its next assignment.
“We are gratified that Ball’s successful architecture for the Deep Impact mission allows NASA to task our viable flyby spacecraft to pursue additional scientific discoveries for a fraction of the cost of a new mission,” said Cary Ludtke, Ball Aerospace vice president and general manager of the Civil and Operational Space business unit.
Ball Aerospace will interface with Michael A'Hearn, EPOXI principal investigator and DIXI science team lead; L. Drake Deming, EPOXI's deputy principal investigator and EPOCh investigation lead; and NASA’s Jet Propulsion Laboratory which provides project management.
NASA had initially planned to send the spacecraft to comet Boethin in December 2009, but astronomers at multiple observatories could not locate the comet in time for the planned flyby of Earth. Scientists theorize comet Boethin may have broken up into pieces too small for detection. NASA then elected to send the Deep Impact flyby to a backup target, comet Hartley 2, (which will occur on New Year's Eve) with the relevant maneuver executed on November 1, 2007.
NASA' s Discovery missions of opportunity are cost-capped solar system exploration missions with highly focused scientific goals. The DIXI mission is designed to provide additional information on how comets were formed and evolved. It would employ both the Ball Aerospace-built Medium Resolution (MRI) and the High Resolution Imagers (HRI) extensively, as well as the onboard spectrometer. The EPOCh investigation also will use Deep Impact’s HRI to observe stars, watching as the giant planets, already known to be orbiting the stars, pass in front of and then behind them. The collected data will be used to characterize the planets and to determine whether they possess rings, moons, or Earth-sized planetary companions. EPOCh's sensitivity will exceed both current ground- and space-based observatory capabilities. EPOCh also will measure the Earth's mid-infrared spectrum, providing comparative data for future efforts to study the atmospheres of extrasolar planets.
