CAPE CANAVERAL, Fla. – Inside the Astrotech payload processing facility near NASA’s Kennedy Space Center in Florida, technicians line up the Radiation Belt Storm Probes, or RBSP, spacecraft A over an electromagnetic source in order to perform a magnetic swing test. The magnetic swing test is performed to characterize the magnetic signature of the spacecraft so that when it is taking measurements with its sensors in space scientists can subtract out background noise from the spacecraft itself. NASA’s RBSP mission will help us understand the sun’s influence on Earth and near-Earth space by studying the Earth’s radiation belts on various scales of space and time. RBSP will begin its mission of exploration of Earth’s Van Allen radiation belts and the extremes of space weather after its launch aboard a United Launch Alliance Atlas V rocket. Launch is targeted for Aug. 23. For more information, visit http://www.nasa.gov/rbsp. Photo credit: NASA/Charisse Nahser
