Future Planetary Robotic Exploration: the Need for International Cooperation, Published 2010, 44 pages. The report from the IAA study on “Future Planetary Robotic Exploration: the Need for International Cooperation” was approved by the Board of Trustees of IAA and presented at the historic Heads of Space Agencies Summit on November 17, 2010 in Washington DC, US. The report reviews the scientific quest to increase our knowledge of the origin and evolution of the solar system, and to search for signs of life within it. It gives a summary of planned robotic exploration activities, as well as challenges and needed R&D solutions. The report addresses in particular: 1) Scientific exploration of the solar system – The driving science goals for the coming decades; 2) Space weather and the characterization of the space environment; 3) R&D investment and key enabling technologies ; 4) Human-mission technology validation; 5) The case and potential areas for international cooperation in robotic and human exploration of deep space.
