The United Launch Alliance Delta IV Heavy rocket, carrying a spy satellite for the National Reconnaissance Office, was originally supposed to lift off over the weekend from Cape Canaveral Air Force Station in Florida.

But launch officials said more time was needed to test and evaluate the swing arm retraction system for the mission, dubbed NROL-44.

ULA set a third launch attempt for the Delta IV Heavy for 11:59 p.m. EDT Tuesday, after weather stopped the launch early Tuesday morning.

The forecast from the 45th Space Wing says the weather for tonight is 40 percent go for launch.

A SpaceX Falcon 9 rocket is expected to launch from Kennedy Space Center on Wednesday. That rocket, carrying a GPS satellite for the U.S. Space Force, was pushed back because of the Delta launch. 

It’s now set for Wednesday, September 30, with a launch window of 9:55 p.m. to 10:10 p.m. The forecast for that launch is far better, 80 percent go for launch.

Another Falcon 9 launch that was supposed to blast off Monday morning with 60 Starlink satellites for SpaceX was pushed back due to poor weather conditions. While SpaceX has not confirmed a new launch date, the 45th Space Wing has posted a forecast for October 1, at 9:12 a.m. The weather would be 70 percent go for launch. 

The last Delta IV Heavy rocket to launch was more than two years ago, back in August 2018.
