 The Atlas 5 rocket's rigid body first stage is known as the Common Core Booster. The CCB replaced the "balloon" pressure-stabilized stage used by previous Atlas vehicles.
It is equipped with the RD-180 liquid-fueled main engine. This liquid oxygen/kerosene powerplant is a two-thrust chamber, two-nozzle engine.
As the CCB's name suggests, the stage is common and is used in all the various configurations of the Atlas 5 family. The booster stage is 106.6 feet long and 12.5 feet diameter.
Augmenting thrust for today's launch are two solid-propellant boosters made by Aerojet Rocketdyne. Considered the world's longest monolithic -- or single-segment -- solid boosters, the motors provide the extra thrust needed to increase the Atlas 5's payload-carrying capacity.
Each booster stands 67 feet tall, has a diameter of just over five feet and weighs 102,000 pounds at launch. The slender white rockets have a lightweight graphite epoxy casing with an erosion-resistant insulation. The solid fuel is high-performance class 1.3 HTPB propellant.
1152 GMT (7:52 a.m. EDT)
 Now 45 minutes from liftoff. Today marks the 64th flight for Atlas 5, born of the Air Force's competition to develop next-generation Evolved Expendable Launch Vehicles. In its previous 63 missions since debuting in August 2002, the Atlas 5 has flown 25 flights dedicated to the Defense Department, 14 commercial missions, 12 for NASA and 12 with spy satellites for the National Reconnaissance Office.
1143 GMT (7:43 a.m. EDT)
 The million-pound Atlas 5 rocket now stands fully fueled with its cryogenic liquid oxygen and liquid hydrogen as the countdown continues on schedule for a liftoff at 8:37 a.m. EDT (1237 GMT).
1142 GMT (7:42 a.m. EDT)
 The liquid hydrogen tank in the Centaur upper stage just reached the 96 percent level. Topping is beginning.
1141 GMT (7:41 a.m. EDT)
 Fast-filling of the first stage liquid oxygen tank has been completed. Topping mode is now underway.

Weather is observed GO for liftoff based on the current conditions and forecast to stay favorable for an 8:37 a.m. EDT (1237 GMT) launch today.

1207 GMT (8:07 a.m. EDT)
Just 30 minutes until liftoff time. The workhorse Centaur upper stage has flown in various configurations for decades. For this launch, the stage will use one Aerojet Rocketdyne-built RL10C-1 liquid oxygen/liquid hydrogen engine that develops a thrust of about 22,890 pounds.

The stage is 41.5 feet in length and 10 feet it diameter. It also houses the navigation unit that serves as the rocket's guidance brain.
1206 GMT (8:06 a.m. EDT)
The fuel-fill sequence for the first stage main engine is starting.
"Были когда-то и мы рысаками!!!"
