Scientific paper

The Explorer-1 [Prime] (E1P) CubeSat mission currently under development in the Space Science and Engineering Laboratory at Montana State University demonstrates the utility of low-cost CubeSats for the study of space weather phenomenon in the near-earth space environment. Using a collimated end window Geiger-Müller tube (donated by Dr. James Van Allen prior to his death in 2006), E1P will monitor the flux of trapped electrons in the horns of the inner and outer radiation belts with energies greater than approximately 60 keV. E1P is a 10cm x 10cm x 10cm satellite with a total mass of less than 1kg. It carries a UHF communications system to support both command uplink and data downlink to our satellite tracking station in Bozeman, Montana. In its nearly circular, low altitude polar orbit and using its continuous real-time telemetry beacon, E1P investigates both temporal and spatial irregularities in radiation belt intensity. The E1P mission will demonstrate the feasibility of a small constellation of similar CubeSats to provide real-time observations of the space environment at a fraction of the cost of larger dedicated spacecrafts. E1P’s secondary goal is to contribute to workforce development by involving university students in its design, development, and operations. E1P is sponsored by the NASA Montana Space Grant Consortium.
