APL Leads Energetic Particle Team Research on NASA's MMS Mission
When NASA's Magnetospheric Multiscale (MMS) mission launched from Cape Canaveral Air Force Station, Florida, on Thursday, March 12, it delivered a four-spacecraft experiment into Earth orbit that will study an important phenomenon called magnetic reconnection. Aboard each of those spacecraft is an Energetic Ion Spectrometer (EIS) instrument, designed and built by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland.
