During launch, the RS-68A ignited to boost the Delta IV medium rocket off the pad. The RS-68A is the world's most powerful liquid-hydrogen/liquid oxygen booster engine, providing 702,000 pounds of liftoff thrust. After the upper stage separated from the launch vehicle, a single RL10B-2 engine ignited to provide 24,750 pounds of thrust to power the upper stage into orbit. For more than five decades, the RL10 has been the United States' most reliable upper-stage engine, accumulating one of the most impressive lists of accomplishments in the history of space propulsion. It has played an integral role in placing numerous military, government and commercial satellites into orbit, and powering space-probe missions to every other planet in the solar system.
The 12 Aerojet Rocketdyne MR-106H monopropellant (hydrazine) thrusters packaged in four modules on the Delta IV upper stage provided roll, pitch and yaw control as well as settling burns for the upper stage. ARDÉ, a subsidiary for
