The ascent propulsion section consists of a constant-thrust, pressure-fed rocket engine, one fuel and one oxidizer tank, two helium tanks, and associated propellant feed and helium pressurization components. The engine develops 3,500 pounds of thrust in a vacuum, it can be shut down and restarted, as requ ired by the mission.

At engine shutdown, the actuator isolation valves are closed, preventing additional fuel from reaching the pilot valves. Simu ltaneously, the pilot valve solenoids are deenergized, opening the acutator ports to the overboard vents so that residual fuel in the actuators is vented into space. With the actuation fuel pressure removed, the actuator pistons are forced back by spring pressure, cranking the propellant shutoff valves to the closed position
