Fleet of satellites and ground-based instruments probes the Sun-Earth System



Space physicists are embarking on a new voyage of discovery of both the inner and outer frontiers of the chain of processes that connects the Sun with the Earth and the other planets. With the successful launch of the POLAR satellite on February 24, 1996, all the elements of the long-awaited Global Geospace Science (GGS) program are in place. GGS is the first phase of an exciting NASA science initiative called the Solar Connections Program, and it is also the primary contribution of the United States to the International Solar Terrestrial Physics (ISTP) Program.
