Progress 64P: Full launch broadcast

Rainy weather expected across Central Florida this weekend has a 50-50 chance of preventing the launch of a SpaceX Falcon 9 rocket Saturday on a resupply mission to the International Space Station, U.S. Air Force forecasters said Wednesday.

Aiming to reduce risk and costs, NASA has decided to launch the first two modules of the Gateway station in lunar orbit on the same heavy-lift rocket in 2023, rather than fly them on separate rockets and dock them together in deep space, according to the the agency’s chief human spaceflight manager.

SpaceX launched the vehicle on a Falcon 9 rocket from Cape Canaveral Space Force Station on Sunday, Sept. 14, at 6:11 p.m. EDT (2211 UTC). It’s scheduled to be berthed to the ISS by NASA astronaut Jonny Kim on Wednesday, Sept. 17.
