CSSP chair Dan Baker and SSB staff officer Art Charo served on the organizing committee for a workshop held on October 16-20 in Wintergreen, Virginia, that brought together more than 100 members of the space science, planetary science, radiation physics, spaceflight operations, and exploration engineering communities. The goals of this Workshop on Solar System Radiation Environment and NASA’s Vision for Space Exploration were to:

  • Increase awareness and understanding of the complex array of solar and space physics issues pertinent to the environments of Earth, the Moon, and Mars;

  • Identify compelling research goals necessary to ensure the success of the Vision for Space Exploration in these environments; and

  • Discuss the directions that research in these fields should take over the coming decades in order to achieve those goals.

A particular emphasis of the workshop was on improving predictions of solar energetic particle storms, the solar eruptions that produce them, and the impact of solar storms on the Earth, Moon, and Mars environments. Members of CSSP were appointed to serve on an ad hoc committee to write a report summarizing workshop discussions on issues such as the current characterization of the heliospheric radiation environment, physical mechanisms of energetic particle acceleration and transport, radiation health hazards to astronauts, radiation effects on materials and spacecraft systems, and mitigation techniques and strategies, including forecasting and operational schemes. The anticipated release of the report is in summer 2006.
