Two intriguing investigations -- One flight-proven spacecraft


EPOXI Newsletter - May/June 2009


  • Characterizing Comet Hartley 2
    Although the EPOXI mission's spacecraft is quietly cruising toward its November 2010 encounter with comet Hartley 2, the EPOXI scientists are staying busy. In his latest update, EPOXI Principal Investigator Mike A'Hearn writes about how the scientists are learning more about the target comet so that they are well prepared to accomplish mission objectives during the flyby.

So who works on EPOXI? Well, many are women and men from the Deep Impact mission, who are preparing for the flyby of Comet Hartley 2 in November, 2010. For this E-News we are featuring two engineers from JPL who are making the mission happen.

  • Meet Tim Larson
    Tim is the Project Manager for both the EPOXI mission and Stardust-NExT. After earning his Bachelor's degree in Mechanical Engineering, Tim worked at Hughes Aircraft Company for 6 years. Since moving over to JPL, Tim has supported several instrument and spacecraft projects, including Deep Impact and Dawn.

  • Meet Rich Rieber
    Space Jock might be simplifying it too much, but Rich does get to send commands to the spacecraft from his console at JPL. He also helps test commands and sequences before they are actually sent. He is an avid outdoorsman who enjoys "hiking, camping, backpacking, and especially rock climbing."

  • Extreme Navigation
    EPOXI EPO team members from Mid-continent Research for Education (McREL) are working with Dr. Art Hammon of JPL on a new activity called Extreme Navigation. The new activity can be used for both EPOXI and Stardust-NExT contexts. Read a story about a recent field test held at Aurora Hills Middle School (CO).

  • Reports
    Spring is a busy time and the EPOXI E/PO team has certainly been busy. Family Science Nights, Maryland Day, Balticon and Maryland's Place in Space are some of the recent events in which they have participated.

EPOXI E-News features information about the mission, its outreach web site, and products, services, and materials available from the EPOXI Education and Public Outreach (E/PO) team. The EPOXI mission combines two exciting science investigations in an entirely new mission that re-uses the Deep Impact spacecraft. The Extrasolar Planet Observation and Characterization (EPOCh) investigation will observe stars that have known transiting giant planets and also observed the Earth as a model for future direct observations of extrasolar Earth-like planets. The Deep Impact Extended Investigation (DIXI) of comets observes comet 103P/Hartley 2 during a close flyby in October 2010. The EPOXI mission is a partnership among the University of Maryland (UMD), the California Institute of Technology's Jet Propulsion Laboratory (JPL), Ball Aerospace and Technology Corp (BATC), and Goddard Space Flight Center (GSFC). EPOXI is a NASA Discovery mission of opportunity. See our website at
