decadal survey released in 2003, The Sun to the Earth -- and Beyond: A Decadal Research Strategy in Solar and Space Physics,1 the scientific challenges to be addressed by the solar and space physics community in the coming decade are as follows: · Understand the structure and dynamics of the Sun's interior, the generation of solar magnetic fields, the origin of the solar cycle, the causes of solar activity, and the structure and dynamics of the corona; · Understand heliospheric structure, the distribution of magnetic fields and matter throughout the solar system, and the interaction of the solar atmosphere with the local interstellar medium; · Understand the space environment of Earth and other solar system bodies and their dynamical response to external and internal influences; · Understand the basic physical principles manifest in processes observed in solar and space plasmas; and · Develop a near-real-time predictive capability for understanding and quantifying the impact on human activity of dynamical processes at the Sun, in the interplanetary medium, and in Earth's magnetosphere and ionosphere.

In showing that interplanetary shocks drive magnetospheric dynamics, these measurements have reemphasized the need for multiple-point space physics measurements at the outer planets. In addition, combining auroral imaging with in situ measurements has yielded new information on how shocks affect auroral emissions.

space activities as a result of policy responses to President Bush's Vision for Space Exploration, announced on January 14, 2004.3,4 This new exploration initiative comes at a time when the solar and space physics community is rapidly developing a connected view of deep-space radiation systems. Researchers are working to understand the network of space radiation environments, to develop capabilities to warn of radiation hazards, to understand how space radiation has affected Earth's climate and biosphere in the past, and to project the effects of these radiation environments on future global sustainability.

In situ and remote-sensing instruments are prominent features of most, if not all, of the space physics mission concepts described in Chapter 4. · Mass, power, and data rates are modest.
