ULA’s 196-foot-tall Atlas V 531 rocket blasted SES-20 and SES-21 satellites into a near geosynchronous (Earth-center) orbit from Space Launch Complex 41 at Cape Canaveral Space Force Station.

The launch went off at 5:36 p.m. EDT, Tuesday.

About the mission

The two broadcasting satellites are from the SES company, which is based in the European country of Luxembourg.

“With SES-20 and -21, SES will continue to deliver C-band broadcast and radio services as well as critical data network services in the coming months,” ULA explained in a press release.

Aerojet Rocketdyne built its RL10C-1-1 engine for ULA’s second stage Centaur, which will take the satellites to their final destinations.

These satellites have their own propulsion systems that will help them orbit at 22,300 miles above the equator, which will operate over the continental United States.

“The satellites will usher in the Federal Communications Commission’s 5G Fast initiative, requiring satellite operators such as SES to clear from the lower 300 MHz to the upper 200 MHz of C-band spectrum to make way for 5G mobile services,” stated ULA.
