However, because of budget constraints and as-yet immature technology, a number of critical investigations must be deferred to a later decade, requiring investments in the coming decade in the areas of technology innovation and development, as well as in ways to more effectively couple theory and data. Studies that combine data from the numerous existing spacecraft will elucidate important aspects of global coupling, while analytical theory, laboratory studies, and especially powerful numerical simulations will complement the various spacecraft measurements in a synergistic attack on the science questions. Other contributions toward accomplishing these goals will come from community-proposed Explorer missions, suborbital flights, CubeSats, operational satellites, and instruments flown on commercial platforms as rides of opportunity. Achieving some of them will require new measurements from strategic missions, either already under development (MMS and RBSP 2) or to be started in the coming decade. These are ambitious goals, and their accomplishment will require intelligent use of the variety of research tools that are available. Identify the structures, dynamics, and linkages in other planetary magnetospheric systems. Determine how magnetosphere-ionosphere-thermosphere coupling controls system-level dynamics. Understand the origins and effects of turbulence and wave-particle interactions. Discover how magnetic reconnection is triggered and modulated. Establish how energetic particles are accelerated, transported, and lost. Understand how plasmas interact within the magnetosphere and at its boundaries. Identify the controlling factors that determine the dominant sources of magnetospheric plasma. Determine how the global and mesoscale structures in the magnetosphere respond to variable solar wind forcing.ġ National Research Council, The Sun to the Earth-and Beyond: A Decadal Research Strategy in Solar and Space Physics, The National Academies Press, Washington, D.C., 2003 and National Research Council, The Sun to the Earth-and Beyond: Panel Reports, The National Academies Press, Washington, D.C., 2003. These eight goals (which are not prioritized) are as follows: 1 This progress has been achieved through a powerful combination of tools, including new data from satellites launched during the decade or just before (e.g., Cluster, IMAGE, THEMIS, TWINS) analysis of data returned from earlier missions data from instruments flown on non-NASA operational satellites measurements from suborbital missions and from networks of ground-based observatories greatly improved numerical simulations analytical theory and laboratory work.įor the coming decade, the Panel on Solar Wind-Magnetosphere Interactions (SWMI) identified a set of eight high-priority science goals for research in solar wind-magnetosphere interactions-goals that follow naturally from the progress that has been made and will contribute substantially toward accomplishing the decadal survey key science goals for solar and space physics identified in Chapter 1 of this report. Significant progress has been made over the past decade in achieving the science objectives identified in the 2003 decadal survey for solar wind-magnetosphere interactions. The resulting dynamic variations in the magnetospheric environment also have important practical consequences for a society that is increasingly reliant on ground- and space-based technological systems that are sensitive to Earth’s space environment. These interactions occur by a number of fundamental physical processes that operate throughout the universe. Its various regions interact globally in complex, nonlinear ways with each other, with the solar wind, and with the upper atmosphere. The magnetosphere is a central part of the solar and space physics system. Report of the Panel on Solar Wind-Magnetosphere Interactionsĩ.1 SUMMARY OF SWMI SCIENCE PRIORITIES AND IMPERATIVES
