America's largest rocket is set to launch a classified satellite into Earth's orbit on Saturday afternoon after stormy weather forced the postponement of Thursday's launch.
The massive Delta IV Heavy rocket will be used to send a large satellite into Earth's orbit for the National Reconnaissance Office; however, the exact details of the satellite and its mission have not been released to the public.
The launch was originally scheduled for Thursday afternoon, but rain, clouds and lightning near the launch pad made the launch unsafe, so the launch was moved to 1:51 p.m. EDT Saturday.
As of Thursday morning, the Air Force's 45th Weather Squadron was predicting that the weather conditions would improve for Saturday, but there is still a 40 percent chance that the weather could interfere with the launch.
The primary weather concerns on Saturday will continue to be rain and thunderstorms, although the thunderstorms are not expected to be as widespread as they will be on Thursday.
