CAPE CANAVERAL, Fla. – At Cape Canaveral Air Force Station in Florida, the United Launch Alliance Atlas V rocket, carrying NASA’s twin Radiation Belt Storm Probes, or RBSP, is rolled back from Space Launch Complex 41 to the Vertical Integration Facility. The rocket and spacecraft will be secured and protected from inclement weather due to Tropical Storm Isaac. 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

Managers decided to roll the Atlas V rocket off the launch pad and back to the Vertical Integration Facility to ensure the launch vehicle and RBSP spacecraft are secured and protected from inclement weather. 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.

CAPE CANAVERAL, Fla. – At Cape Canaveral Air Force Station in Florida, the United Launch Alliance, or ULA, Atlas V rocket carrying NASA’s twin Radiation Belt Storm Probes, or RBSP, heads to the launch pad after rolling out of the ULA Vertical Integration Facility at Space Launch Complex 41 at 1:59 p.m. EDT. The Atlas V rocket had been rolled back to the facility on August 26 to ensure the launch vehicle and RBSP spacecraft were secured and protected from inclement weather caused by Tropical Storm Isaac.
