Meteorologists with the U.S. Air Force 45th Space Wing predict a 60 percent chance of favorable weather for liftoff of the SpaceX Falcon 9 rocket for the company’s 20th commercial resupply services mission to the International Space Station. Launch is scheduled for Friday, March 6 at 11:50 p.m. EST from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. Skies will clear through the day Friday, and winds will become gusty out of the north as a high-pressure area moves east. The primary weather concern for launch is liftoff winds with the tight pressure gradient behind the front.
