CAPE CANAVERAL — SpaceX’s Falcon 9 rocket continues to sit on a pad at Cape Canaveral Air Force Station after the company scrubbed its fourth launch attempt Tuesday.
SpaceX CEO Elon Musk said on Twitter that upper-level winds were to blame, making Friday the next available opportunity to launch the SES-9 communications satellite from Launch Complex 40.
“Hits like a sledgehammer when going up supersonic,” Musk said to describe what a rocket would face in those conditions.
A specific launch window for the fifth attempt was not discussed.
Phillip Larson, a SpaceX spokesperson, said in a release that the upper-level winds are likely to exceed acceptable limits through Thursday.
“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,” he said.
The Air Force’s 45th Weather Squadron had described conditions as 80% favorable for a launch attempt. A forecast for Friday has not yet been released.
