CAPE CANAVERAL, Fla. – Spotlights bounce off the clouds over Space Launch Complex 41 on Cape Canaveral Air Force Station as NASA's Radiation Belt Storm Probes, or RBSP, lift off the pad at 4:05 a.m. EDT aboard a United Launch Alliance Atlas V rocket. In the foreground, at left, is the countdown clock at the Press Site at NASA's Kennedy Space Center. 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.
