SPRINT-B (ERG) is a Japanese research satellite designed to repeatedly fly through the Van Allen belts high above Earth, helping scientists sort out how chaotic geomagnetic storms form and evolve and potentially endanger astronauts, spacecraft and infrastructure vital to life on the ground. The satellite will be nicknamed Arase after a river running near the Uchinoura Space Center in Japan's Kagoshima prefecture. Arase, a Japanese word for a river raging with rough white water, is a fitting description for the journey that lies ahead of ERG, referring to the satellite's perilous passes through a zone of intense radiation.
