In 2003, the National Research Council (NRC) published the first decadal strategy for solar and space physics: The Sun to the Earth—and Beyond: A Decadal Research Strategy in Solar and Space That report included a recommended suite of NASA missions that were ordered by priority, presented in an appropriate sequence, and selected to fit within the expected resource profile for the next decade. In early 2004, NASA adopted major new goals for human and robotic exploration of the solar system, exploration that will depend, in part, on developing the capability to predict the space environment experienced by exploring spacecraft. The purpose of this report is.
