On the first flight of the Space Launch System, the CuSP secondary payload will serve as a “space weather station” to measure particles and magnetic fields in space. This test will provide data to see if it would be practical to launch many more CubeSats around Earth to monitor space weather. These would mimic the way terrestrial weather sensors monitor weather all over the globe. This is one of two payloads selected by NASA’s Science Mission Directorate. LunaH-Map, the other Science Mission Directorate payload
will map hydrogen within craters and other permanently shadowed regions throughout the moon’s South Pole.
