Rocket will try out new boosters on this launch.
Update 6:15pm EST: A ground-systems issue got United Launch Alliance again. Prior to the opening of the Atlas V launch window on Wednesday evening, an issue related to ground-system liquid-oxygen valves could not be solved in time for a launch attempt from Florida.
The company will now stand down for 48 hours to address the issue, which would allow for SpaceX to attempt a launch of a GPS III satellite for the Space Force on Thursday.
Original post 11:25am EST: United Launch Alliance returns to one of its two main pads at Cape Canaveral Air Force Station Wednesday to try to break a string of recent launch scrubs due to various issues, mostly related to ground systems.
The company's Atlas V rocket is scheduled to liftoff from Space Launch Complex-41 at 5:54pm EST (22:54 UTC), carrying a satellite for the National Reconnaissance Office. The mission is named NROL-101, and its final orbit is classified. There is a 70-percent chance of favorable conditions.
