Injun 2 satellite
The Injun program was a series of six satellites designed and built by researchers at the University of Iowa to observe various radiation and magnetic phenomena in the ionosphere and beyond.
The design specifics of the satellites had little in common, though all were solar-powered and the first five used magnetic stabilization to control spacecraft attitude. (The last in the series was spin-stabilized). Instruments included particle detectors of varying types, magnetometers , and photometers for observing auroras .[1] Explorer program of the NASA .
In spite of various hardware difficulties and the loss of Injun 2 due to an upper stage failure, the program was generally successful. In particular, they produced data on the Van Allen radiation belts including electrical convection in the magnetosphere ,[2] Starfish Prime high-altitude nuclear test .[3]
