Energetic Particles Explorer

Energetic Particles Explorer ( EPE , originally S-3 ) was a series of four science satellites in the Explorer program of NASA . They were used to study charged particles in the earth's magnetic field and in the solar wind .
In order to enable the investigation of the radiation belts , the satellites were brought into highly elliptical orbits by the Cape Canaveral Air Force Station with delta rockets .
Explorer 15 specially served by the exploration of the starfish-Prime - Nuclear test resulting artificial radiation belt.
construction
The satellite structure had the shape of an octagonal prism, which ended on the underside with a conical adapter to the launch vehicle . Four solar cell booms arranged like a windmill were unfolded after take-off and served to supply the satellites with energy. A magnetometer was attached to a mast on top .
The EPE series satellites were spin stabilized .
The instrumentation consisted of the magnetometer and various protons - electrons - and plasma - detectors .
