NASA’s SpaceX Crew-4 launch is targeted at 3:52 a.m. EDT Wednesday, April 27, to the International Space Station from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
The U.S. Space Force 45th Weather Squadron predicts a 90% chance of favorable weather conditions at the launch pad for liftoff of the Crew-4 mission based on Falcon 9 Crew Dragon launch weather criteria. The primary weather concerns for the launch area are the cumulus cloud and flight through precipitation rules. Teams also will monitor weather conditions both for the launch area and downrange for the flight of Crew Dragon.
NASA will provide coverage of the upcoming prelaunch activities for the mission sending astronauts to the microgravity laboratory. Prelaunch activities will air live on NASA Television, the NASA app, and the agency’s website. NASA’s SpaceX Crew-4 prelaunch coverage is as follows (all times Eastern):
