Watch an Atlas V rocket launch 2 communications satellites on Tuesday

A United Launch Alliance (ULA) Atlas V rocket will launch two business communications satellites to orbit Tuesday (Oct. 4), and you’ll watch the liftoff stay.

A 196-foot-tall (60 meters) Atlas V topped with the SES-20 and SES-21 spacecraft is scheduled to raise off Tuesday at 5:36 p.m. EDT (2136 GMT) from Cape Canaveral House Pressure Station in Florida.

Three different missions are on faucet for Thursday (Oct. 6) as properly, together with a Rocket Lab launch that can ship to orbit a satellite tv for pc constructed by the power and technology agency Basic Atomics. 

As well as, SpaceX plans to loft one other huge batch of its Starlink web satellites within the coming days; the timing depends upon whether or not or nor Crew-5 will get off the bottom as deliberate on Wednesday, firm representatives mentioned by way of Twitter on Monday (opens in new tab) (Oct. 3).
