CAPE CANAVERAL, Fla. – At Cape Canaveral Air Force Station in Florida, United Launch Alliance, or ULA, technicians monitor the progress as the Atlas V rocket carrying NASA’s twin Radiation Belt Storm Probes, or RBSP, is moved into the Vertical Integration Facility after rolling back from Space Launch Complex 41. The rocket and spacecraft will be secured and protected from inclement weather due to Tropical Storm Isaac. The RBSP logo on the Atlas V rocket is not a decal. For this mission, the logo was hand painted onto the rocket. 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. The launch is rescheduled for 4:05 a.m. EDT on Aug. 30, pending approval from the range. For more information on RBSP, visit http://www.nasa.gov/rbsp. Photo credit: NASA/Ben Smegelsky
