CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, astronaut Leland Melvin, associate administrator of NASA Education, talks to agency social media followers during the second day of NASA Social activities revolving around NASA's Radiation Belt Storm Probes, or RBSP, mission. The probes are set to launch aboard a United Launch Alliance, or ULA, Atlas V rocket from nearby Cape Canaveral Air Force Station. About 40 followers were selected to participate in RBSP's prelaunch and launch activities. The 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. For more information, visit http://www.nasa.gov/rbsp.
