An Atlas V rocket took off Tuesday night (Oct. 4) from Florida’s Space Coast, bring 2 business interactions satellites to orbit.
The Atlas V, topped with the twin SES-20 and SES-21 spacecraft, released Tuesday at 5: 36 p.m. EDT (2136 GMT) from Cape Canaveral Space Force Station.
The 196- foot-tall (60 meters) rocket struck all of its marks early. It rejected its 3 strong rocket boosters about 2 minutes after liftoff as prepared, for instance, and discarded its payload fairing, which secured the 2 satellites throughout launch, about 1.5 minutes later on. And the Atlas V’s 2 phases separated at about T +4.5 minutes.

But there’s a fair bit of work delegated do, for the rocket’s Centaur upper phase still requires to power itself to the implementation locations for SES-20 and SES-21– near-circular, near-geosynchronous orbits high above Earth.
If all goes according to strategy, SES-20 will be released about 5 hours and 40 minutes after liftoff, and SES-21 will do the same approximately 40 minutes later on. The 2 spacecraft will then utilize their onboard propulsion systems to circularize their orbits, which will send them zooming around Earth about 22,300 miles (35,900 kilometers) above the equator, according to a ULA objective description(opens in brand-new tab)
Once the satellites are developed in those orbits and have actually been through a checkout duration, SES-20 and SES-21 can start doing what they were developed to do– offer tv broadcasting service throughout the United States for the Luxembourg telecom business SES.
” Built by Boeing with countless narrow and steerable beams and the capability to separate disturbance sources, the 2 spacecraft supply SES and future clients the capability to broaden, extend or perhaps alter a satellite’s protection location and objective throughout its life,” ULA agents composed in the objective description.
” Proven hardware paired with next-generation innovation produced a cost effective and light-weight spacecraft, allowing 2 satellites to release on a single rocket,” they included.
The Atlas V launch becomes part of a hectic week in spaceflight. SpaceX prepares to release the Crew-5 astronaut objective for NASA and another batch of the business’s Starlink web satellites on 2 different objectives on Wednesday (Oct. 5), as well as 2 telecom satellites for the business Intelsat on Thursday (Oct. 6).
Three other objectives are on tap for Thursday (Oct. 6) too, consisting of a Rocket Lab launch that will send out to orbit a satellite developed by the energy and innovation company General Atomics.
