Weather concerns continue as NASA and Boeing look to launch the Starliner capsule on a vital uncrewed test flight to the International Space Station on Tuesday (Aug. 3).

Launch is targeting 1:20 p.m. EDT (1720 GMT), and current weather patterns are favoring afternoon showers and thunderstorms along the eastern coast of Florida, according to the 45th Weather Squadron, which monitors conditions for launches from the Kennedy Space Center and the Cape Canaveral Space Force Base. There’s a 40% chance the weather will permit Tuesday’s launch, according to the office’s current forecast, which suggests that Starliner may be able to blast off the pad before troubling weather rolls in.
