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

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).
