Winds postpone SpaceX launch | SpaceNews.com
WASHINGTON — High winds in the upper atmosphere have led SpaceX to postpone an already delayed Falcon 9 launch by at least three more days, the company announced March 1.
SpaceX Chief Executive Elon Musk tweeted that wind speeds approaching 70 meters per second at an altitude of 10 kilometers led the company to postpone the fourth attempt to launch the SES-9 communications satellite. “Hits like a sledgehammer when going up supersonic,” he said in a tweet describing what he called “extreme high altitude wind shear.”
Because the high upper level winds are forecast to persist through March 3, SpaceX has rescheduled the launch for no earlier than March 4. “Our team will continue working with the Air Force’s Launch Weather Officer to evaluate the best available opportunity for flight in the coming days,” SpaceX said in a statement. Weather forecasts had previously predicted an 80 percent chance of acceptable weather for launch opportunities on March 1 and 3.
