IMP-8 Mission

Objectives and Applications

The eight satellites of the Interplanetary Monitoring Platform, or IMP, series were designed to study the boundary between Earth’s magnetic environment and interplanetary space, along with the radiation – both from the sun and from outside the solar system – that passes between the two. The IMP satellites provided measurements of solar wind and cosmic ray parameters, including everything from energetic particle flux to magnetic field measurements to plasma parameters. The consistent IMP observations were the baseline for tracking the solar cycle, deep-space studies, and understanding Earth’s magnetic environment.
