Observations of low-energy plasma composition from the ISEE-1 and SCATHA satellitesThis brief review is concerned with some of the initial measurements of low-energy ion properties conducted with the aid of ion composition detectors aboard the ISEE-1 and SCATHA satellites. ISEE-1 was launched in October 1977 into a highly elliptical orbit, while SCATHA was launched in January 1979 into a near geosynchronous orbit. Attention is given to the origin of low-energy plasma, the energization of ionospheric ions, the transport of ionospheric ions, and the loss of low-energy plasma from the magnetosphere. According to results obtained during the past several years, including the present ISEE-1 and SCATHA results, there are significant, and occasionally dominant, concentrations of He(+) and O(+) in various locations within the magnetosphere.
