Jupiter rendezvous

UI instrument, researchers involved in NASA’s Juno mission
On Independence Day, a NASA spacecraft entered Jupiter’s orbit, and the University of Iowa had an instrument along for the ride. The Plasma Waves Instrument, designed and built at the UI, will sample plasma waves and learn how Jupiter’s intense auroras are produced.

UI researchers help answer long-standing question about Van Allen radiation belts

Electron acceleration occurs in the heart of the radiation belts
University of Iowa researchers and their colleagues have found that the energy in the Earth’s Van Allen radiation belts originate within the belts themselves, from accelerating electrons. Results appear in the journal Science Express.
