PARIS, June 24 (Xinhua) -- The France-based Arianespace announced Wednesday overnight that the scheduled dual-payload mission of Ariane 5 was postponed due to subsystem anomaly.
"Tonight's Ariane 5 mission with the Arabsat-5A and COMS satellite passengers was postponed when a launcher subsystem anomaly occurred during the final countdown," the company said in a statement near twenty minutes after the final countdown was interrupted.
The launcher company said an investigation has been initiated to find the cause and the two commercial satellites were safe on the launch pad atop the heavy-lift Ariane 5 ECA.
"A new launch date will be announced as soon as possible," the brief statement concluded.
The second Ariane 5 flight of 2010 was expected to take off on Wednesday afternoon in French Guiana during a launch window that opens from at 6:41 p.m. to 7:45 p.m. local time (GMT 2141 to GMT 2245).
Built by Astrium and Thales Alenia Space, the Arabsat-5A, will serve for the Arabsat telecommunications operator and is to operate at an orbital location of 30.5 degree East. The spacecraft will provide telecommunications and TV broadcasting services over the Middle East and Africa. The other passenger, South Korea's COMS (Communication, Ocean and Meteorological Satellite) is fitted with three payloads for meteorological observation, ocean surveillance and experimental broadband multimedia communications services.
