ULA set to launch Atlas V on long duration mission for Space Force

ULA (United Launch Alliance) is preparing for the 90th launch of an Atlas V rocket and their fifth and final mission of 2021. Launching from SLC-41 (Space Launch Complex 41) in Cape Canaveral, Florida, the STP-3 mission will loft two experimental satellites for the United States Space Force. The mission will also test several new technologies onboard the company’s Atlas V launch vehicle during the longest duration mission for an Atlas rocket to date. After a 24 hour delay due to a leak in the RP-1 ground storage system and then an additional day to verify the fuel’s sample integrity, liftoff is now scheduled for December 7 at 4:04 AM EST (9:04 UTC).
