Weather conditions at the surface will likely be favorable for the launch of a SpaceX Falcon 9 rocket Wednesday from Cape Canaveral, but upper level winds may pose a roadblock for the start of the company’s next space station resupply mission. SpaceX is targeting liftoff of the Falcon 9 from pad 40 at 12:51 p.m. EST (1751 GMT) Wednesday.
