The Atlas V 421 was manufactured by United Launch Alliance with the first launch on 2007-10-11. Atlas V 421 has 9 successful launches and 0 failed launches with a total of 9 launches. Atlas V is an expendable launch system in the Atlas rocket family. It was formerly operated by Lockheed Martin and is now operated by United Launch Alliance (ULA), a joint venture with Boeing. Each Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage. The RD-180 engines are provided by RD Amross, while Aerojet Rocketdyne provides both the RL10 engines and the strap-on boosters used in some configurations. The 421 version uses a 4m wide fairing, 2 solid rocket boosters and one engine on the Centaur stage.

ULA was formed in December 2006 by combining the teams at these companies which provide spacecraft launch services to the government of the United States. ULA launches from both coasts of the US. They launch their Atlas V vehicle from LC-41 in Cape Canaveral and LC-3E at Vandeberg. Their Delta IV launches from LC-37 at Cape Canaveral and LC-6 at Vandenberg.
Great track record for this Atlas 421. Well done to the team at ULA and maintaining our security a high priority.
GO GO GO GO GO, YOU CAN DO THIS ULA! I hope all go well for this mission because it alerted me.
Someone please enlighten me, “How do you get a temperature of 43F at launch?”
We will have Rocket Monkey look into it.
The launch is at 17:37 whatever that is. Watching the live ULA feed. I think. No they said 1:37; is that 17:37??
The rocket already launched, but this website hasn’t refreshed. Watching the live ULA feed. Successful so far
The video feed is the best place to get updates during the launch.
