The Mars Exploration Program Still Following the Water Doug McCuistion Director, Mars Exploration Program NASA HQ Science Mission Directorate International Workshop March 8-10, 2005

Agenda Mars Exploration Program – The Current Decade Next Decade of Mars Exploration Strategic Roadmapping and the US National Vision Review of Key Messages from the 2004 International Workshop

Mars Exploration Program - the Current Decade 2 Most of you are pretty familiar with this chart, and the missions in the Mars Exploration Program in this decade. Mission & Technology development follows pathways similar to the discovery-drive science program Pathways guide the DIRECTION of the next decade’s missions, but not at the payload/instrument level. Architectural outlines, objectives, and constructs are set but flexibility allows mission selection and technology infusion as science discoveries drive the needed missions & measurements. Missions in this decade are pretty well set—MRO in 2005, Phoenix in 2007. Opportunities still exist in 2009 with MTO and MSL………

International Partnerships Extensive International cooperation has been successful in the Mars Program MGS – France, Austria Odyssey – Russia, France MER – Germany, Denmark MRO – Italy, UK MEX – US on ESA s/c Phoenix – Switzerland, Germany, Denmark, Canada MSL – Spain, France, Russia, Canada, Germany Mars Exploration Program intends to continue, and hopefully expand, international partnerships

Key Topics from November Workshop Mars is the central exploration focus for nearly all countries Most countries haven’t identified the Moon as stepping stone to Mars in their strategic planning (with robotic precursors) Current planning in countries other than the U.S. is driven by the science priorities developed within their own science constituencies and the global marketplace Mars Sample Return was the highest Mars priority in general Most countries are application-driven Their missions and products have to be traced to specific technologies with clearly-defined societal benefits A large amount of technology development will be required to enable exploration There are a lot of relevant technologies that are planned or being developed that will be extremely valuable to exploration Everyone is excited about the potential for true collaboration This workshop is a good first step – engaging potential partners before plans are set in stone We need to learn the lessons from past collaborative efforts There are many robotic missions planned to both the Moon and Mars Collaboration on key missions such as Mars Sample Return is advantageous for all Sharing of data from missions is essential to moving forward in a collaborative way This is an area where innovative new practices could be of great benefit to Exploration

Science Mission Directorate (SMD) International Conference An opportunity to continue our dialog on collaboration Workshop Goals Present NASA/SMD’s sceince priorities, especially in light of the National Vision for Space Exploration Identify areas for mutually beneficial collaboration in science Build on existing and ongoing relationships, as well as dialog from the Exploration Workshop in November 2004

In Conclusion…. NASA’s Mars Exploration Program is healthy, continuing to make new discoveries NASA strategic roadmapping activities have the potential to yield great opportunities, as well as new challenges Human Exploration precursor technology and mission needs are being integrated Mars Science will have additional opportunities with the US National Vision (and Aurora?) We must work together—human exploration and science—through … strategic collaborations, tactical contributions, and robust commitments

Backup

Actions from November Workshop Most agencies indicated a strong interest in the Science Mission Directorate International meeting next March Action by 2/05: Ensure workshop agenda is synergistic with Exploration and we clearly communicate the intersection of the two programs (COMPLETE) International Working Groups are and effective mechanism for developing strategies and roadmaps (I.e. Mars Exploration Program Working Group) Action by 1/05: Ensure we have adequate International participation in these groups and that the charters are synergistic with Exploration. Lunar Exploration Program Analysis Group is next step. (COMPLETE) Some agencies indicated a desire for bi-lateral discussions regarding the key capabilities we identified. Action by 4/05: Determine the requirements, schedule, content of bi-lateral discussions regarding key capabilities. Sharing of data from missions is essential to moving forward in a collaborative way Action by 8/05: Determine strategy for developing common access to mission data. (SELENE is first step) There are many robotic missions planned to both the Moon and Mars Action by 8/05: Engage key agencies in Roadmapping activities in order to suggest the best near-term mission sets for a collaborative program. (Common action with Session #1).
