Interplanetary Monitoring Platform
Interplanetary Monitoring Platform was a program managed by the NASA Goddard Space Flight Center in Greenbelt, Maryland, as part of the Explorers program, with the primary objectives of investigation of interplanetary plasma and the interplanetary magnetic field. The orbiting of IMP satellites in a variety of interplanetary and earth orbits allowed study of spatial and temporal relationships of geophysical and interplanetary phenomena simultaneously by several other NASA satellites.[1]
