Colorado Inner Radiation Belt Experiment

Elucidating inner radiation belt electrons

The Colorado Inner Radiation Belt Experiment 3U CubeSat goal is to gain a better understanding of the formation of the inner radiation belt electrons as well as determine where these particles come from and how they behave. The proposed goal of the CIRBE mission is to provide state-of-the-art measurements of .3-3.5 MeV electrons (and 6-35 MeV protons) in the Earth’s radiation belt in a highly inclined Low Earth Orbit.
