Objectives and Applications
|
The goal of the mission is to detect the Van Allen radiation belts in honor of the 50th anniversary of the Explorer-1 mission (launch January 31, 1958), America's first satellite that first discovered the cloud of highly energetic electrons trapped in the Earth's magnetic field. Shortly after launch, the E1P-2 mission was renamed to HRBE (Hiscock Radiation Belt Explorer), in honor of Dr. William A. Hiscock, the founder and former director of the MSGC (Montana Space Grant Consortium).
