March 21, 2006 - The second launch attempt of NASA's Space Technology 5 spacecraft is scheduled for Wednesday, March 22 at 9:02 a.m. EST. NASA TV begins live coverage at 7:30 a.m. EST.
Departure of the L-1011 aircraft carrying the Orbital Sciences Pegasus XL rocket and ST5 is scheduled for 8:04 a.m. EST, from Vandenberg Air Force Base, Calif. The Pegasus/ST5 launch is targeted over the Pacific Ocean, 145 miles northwest of Vandenberg. The launch window closes at 10:20 a.m. EST.
The weather forecast on Wednesday is generally favorable with an 80 percent chance of meeting launch criteria.
During the first launch attempt on March 15, the Pegasus starboard flight control surface fin pin did not retract resulting in an aborted attempt. NASA and Orbital Sciences completed an engineering analysis, but the exact cause of the malfunction could not be determined. The most likely reason was the pin retractor system failed to operate due to the formation of ice. Full Story

News, Spacecraft, ST5
NASA's Space Technology 5 (ST5) spacecraft is scheduled to launch from an Orbital Sciences Pegasus XL vehicle at 6:02 a.m. PST (9:02 EST) on March 14 within a launch window that extends from 5:57 to 7:19 a.m. PST. The drop point of the Pegasus from the L-1011 carrier aircraft is a location over the Pacific Ocean approximately 100 miles offshore west-northwest of Vandenberg Air Force Base, Calif. ST5 will be launched at an azimuth of 105.6 degrees into an elliptical polar orbit of 186 miles by 2,796 miles.
The New Millennium Program's ST5 spacecraft consists of three miniature satellites called "micro-sats." ST5 will flight-validate innovative technology concepts to reduce risks to future science missions.
Although only 55 pounds each, the satellites have capabilities comparable to those of much larger spacecraft. ST5 will demonstrate the ability of small satellites to perform research-quality science by taking measurements of the Earth's magnetic field using highly sensitive magnetometers.
NASA's Kennedy Space Center in Florida is responsible for launch vehicle and spacecraft integration and launch countdown management. NASA's Goddard Space Flight Center in Greenbelt, Md., is responsible for the overall ST5 mission management, the spacecraft and associated technology development. Orbital Sciences Corporation is responsible for providing the Pegasus XL launch service to NASA.
