CAPE CANAVERAL, Fla. – NASA's Radiation Belt Storm Probes, or RBSP, lift off Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida aboard a United Launch Alliance Atlas V rocket at 4:05 a.m. EDT. RBSP will explore changes in Earth's space environment caused by the sun -- known as "space weather" -- that can disable satellites, create power-grid failures and disrupt GPS service. The mission also will provide data on the fundamental radiation and particle acceleration processes throughout the universe. For more information on RBSP, visit http://www.nasa.gov/rbsp.
