Two intriguing investigations -- One flight-proven spacecraft


EPOXI Newsletter - Nov 2011


We hope you have enjoyed getting these newsletters and learning about the EPOXI mission. Now that the mission is finished and with the 1 year anniversary just days away, we're sending out this last newsletter. You can still stay in touch via our webpage, Facebook and Twitter accounts, but we won't be sending any more newsletters. So, what will happen to all of your email addresses? Well, Dr. Jessica Sunshine, a science team member of Deep Impact and the Deputy PI for EPOXI, has a mission proposal called Comet Hopper. If it is selected, we plan on migrating the newsletter list over to that mission's EPO team so that you can start learning about that new comet mission. If you'd rather not get any more mission newsletters at all, you can opt out by unsubscribing at



  • Status Report
    Since the flyby last November, the science team has been busy analysing the data, writing papers and going to professional conferences. Dr. A'Hearn briefly summarizes some of the findings presented at the most recent meeting as well as giving a quick comment about the spacecraft's future.

  • Deep Sky Feasibility Demonstration
    With the successful completion of the Deep Impact and EPOXI missions, the Deep Impact Flyby spacecraft has proven that it can get great data on comets. What else could it do? EPOXI Spacecraft Team Chief Steve Wissler needed to give his team some real life practice by imaging some targets that are definitely not comets!


As this is the final EPOXI Mission newsletter, we invite our readers to look back though the biographies of our team members to learn about the interesting people who helped make the mission a success. And since many of the EPOXI team members were also part of Deep Impact, you should take a look back through those as well!

  • Comparing Comets
    Students in grades 7-12 and college have the opportunity to play the role of cometary scientists and use images from Stardust, Deep Impact and EPOXI to study and compare the surfaces of three comet nuclei from close range.

  • Facebook
    Become a fan of the EPOXI Mission on Facebook! There probably won't be any more newsletters from EPOXI, but we'll continue to post new updates to Facebook. Check out images of 103P/Hartley posted by fans and take advantage of opportunities to chat with "Deep Impact Flyby."
  • Twitter
    Not on Facebook! That's all right, you can stay up to date by following "cometexplorer" on Twitter.
  • "Add This" Share Button
    Did you see an interesting page on the EPOXI website? Want to share it with your friends? It's now easier to do that since we've added a Share Button on all of the pages. You can post a page to your Facebook, MySpace or other social network. You can also email, Digg, Twitter... Just look for the "Add This" button in the left column on any page.

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 combined two exciting science investigations in an entirely new mission that re-used the Deep Impact spacecraft. The Extrasolar Planet Observation and Characterization (EPOCh) investigation observed stars that are known to have transiting giant planets. The Deep Impact Extended Investigation (DIXI) of comets observed comet 103P/Hartley 2 during a close flyby in November 2010. The EPOXI mission was 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 was a NASA Discovery mission of opportunity. See our website at
