MISSION: Galaxy Evolution Explorer (GALEX)
LAUNCH VEHICLE: Pegasus XL
LAUNCH SITE: Cape Canaveral Air Force Station
LAUNCH DATE: Under Review
LAUNCH WINDOW: TBD

The GALEX spacecraft is at the Orbital Space Systems Group facility in Dulles, Virginia. Due to spacecraft problems found during thermal vacuum testing of the spacecraft, shipment to KSC has been postponed while troubleshooting and further testing and data analysis is performed.

In California at Vandenberg Air Force Base, the Pegasus XL launch vehicle is ready for ferry to KSC on the Orbital Sciences L-1011 aircraft but is predicated on the arrival of the spacecraft at KSC. The launch has not been rescheduled at this time.
