The Common Core Booster is powered by a single RD-180 engine, derived from the RD-170 developed by the Soviet Union to power its Zenit rocket.
So is the RD-180 a two chamber and exhaust engine?
Because there are two nozzles on the first stage picture which surprised me when I read the quote in the article. If there is only one above engine there that would make sense.

Yes RD-180 is a two chamber engine.
What's so surprising about it?

Does TDRS-L have a gas cap to allow for future in-flight servicing? If MDA or another company actually brings to market a satellite servicing spacecraft, it would be nice if TDRS satellites provided access to re-fuel.

No spacecraft at this time have gas caps.

Isn't it a single chamber, two nozzle engine?

Two combustion chambers and two nozzles that share hardware upstream, making it one Engine.

I'm happy ULA kept the heritage of the tankage around those nozzles. You can look at it and know its an "Atlas"

Tankage and key word "Heritage", word "look" should have been added.

Nothing - It would have been surprising if it wasn't a two chamber engine with the two nozzles.

Nice underbelly views of Atlas 5 during rollout.
Can you see a guy on the platform holding and squeezing a nozzle while hearing dings from the meter on the pump as RP-1 is loaded into the vehicle.?

Nice to see an airborne shot of an ARIA aircraft during the history of TDRS development clip. I listened to numerous launches out of Vandenberg on HF long before launches were streamed live. Data was usually relayed via LES satellites. There's an ARIA nearby at the Museum of the US Air Force.
