Booster problem scrubs Ariane 5 launch
Posted: Sat, Sep 9, 2017, 10:50 AM ET (1450 GMT)
A rare last-second scrub delayed Tuesday's Ariane 5 launch of two communications satellites. The rocket's cryogenic main engine started up as the countdown reached zero for the launch from Kourou, French Guiana, but the launch was aborted before the solid-fuel boosters ignited, scrubbing the launch for the day. The company said Wednesday that the last-second abort during Tuesday night's launch attempt was caused by an electrical equipment issue in one of the rocket's two solid-fuel boosters, detected after the main engine started but before the boosters ignited. The launch has been rescheduled for late September. The Ariane 5 is carrying the Intelsat 37e and and BSAT-4a communications satellites.
