Update, September 26: This launch was again delayed due to continuing problems with the swing arm system at Launch Complex 37. Teams are now targeting just after midnight on Monday, September 28th. Subsequent launches – two SpaceX Falcon 9 missions – will also be delayed.

See the latest launch schedule here.

Update: This launch has been postponed to 10:22 on Monday, September 28, due to a previous launch (Delta IV Heavy) that brought it forward. The following story was reflected to update the new window.

Weather conditions are expected to be mostly favorable for SpaceX’s upcoming launch from Kennedy Space Center with 60 satellites broadcasting the internet, the Space Force said Friday.

If schedules and weather conditions hold up, a 230-foot Falcon 9 rocket will face 80% of the “start” conditions for its scheduled 10:22 AM takeoff from Pad 39A on Monday. Cumulus clouds and possible showers have been reported by meteorologists as their main concerns.

“The remnants of what was once tropical storm Beta will move to the southeastern United States over the next few days, bringing a wave of humidity across Florida,” said the 45th Weather Storm. “The sea breeze should move inward very close to the primary launch window in time.”

If the mission were to delay until Tuesday morning due to technical or weather problems, conditions would drop to 60% “off” and the launch time would return around 10:00.

After take off, the rocket’s first stage will target a drone ship landing in the Atlantic Ocean as long as conditions at sea are favorable. If the seas are too rough, the ship may have difficulty maintaining its position, forcing SpaceX to clean up the mission entirely.

Monday’s flight will mark SpaceX’s thirteenth launch of a Starlink payload, which is part of the company’s overall effort to provide Internet connectivity from space. Once deployed from the second stage, SpaceX will have launched around 780 satellites, though some have since deorbitated and burned in the atmosphere as expected.

But before the Falcon 9 can fly, a United Launch Alliance Delta IV Heavy rocket must first clear the area. That 235-foot three-core rocket is slated for launch from Cape Canaveral Air Force Station Launch Complex 37 with an intelligence-gathering satellite at 12:10 pm on Sunday.

So, just a few days later, on Tuesday, another Falcon 9 is scheduled to launch, this time from Cape’s Launch Complex 40. 9:55 pm. Takeoff will push a Global Positioning System satellite into orbit for the Space Force and Air Force.
