KOUROU, French Guiana (Reuters) - High-altitude winds scrubbed anew the scheduled launch of Western Europe`s 105th Ariane rocket carrying two satellites, space officials said on Tuesday. Countdown was stopped six minutes before the planned liftoff from the European Space Agency (ESA) launch center in Kourou, French Guiana on the northeast coast of South America when a weather report detected high-altitude winds outside acceptable safety levels. A first attempt to launch the rocket was abandoned on Friday for the same reason. Countdown was stopped a second time on Saturday and weather conditions on Sunday and Monday did not permit the countdown to be started. Weather conditions improved earlier on Tuesday and a new countdown was started. But conditions degenerated during the day causing a new halt. Officials said a new countdown could be attempted on Wednesday if weather conditions improved. The Ariane-4 rocket was scheduled to launch the BRASILSAT B3 satellite for Rio de Janeiro-based operator Embratel and INMARSAT-3F5 a satellite for London-based mobile satellite operator INMARSAT.
