Ariane 5’s mission with Arabsat-5A and COMS has entered the final countdown
The final countdown is now underway for tonight’s dual-passenger Ariane 5 mission from Europe’s Spaceport, which will orbit the Arabsat-5A and COMS satellite payloads.
Activities began with this morning’s electrical systems checkout for the heavy-lift launch vehicle, and are being followed by the fueling of Ariane 5’s cryogenic main stage and upper stage.
After being orbited by Arianespace, Arabsat-5A will be utilized by the Arabsat telecommunications operator for telecommunications and TV broadcasting services over the Middle East and Africa. COMS is a satellite for the Korea Aerospace Research Institute (KARI), which is to perform meteorological observations, ocean surveillance and experimental broadband multimedia communications services.
Ariane 5’s liftoff is scheduled during a launch window that opens at 6:41 p.m. and continues to 7:45 p.m., local time in French Guiana.
