From Interstellar Wiki
The Ranger is a single-stage-to-orbit (SSTO) reconnaissance spacecraft built and used by NASA. Two Rangers were part of the Endurance mission, named Ranger 1 and Ranger 2. Twelve additional Rangers were also built launched for the Lazarus missions ten years prior. The Ranger is designed along the lines of a lifting body, but is equipped with small, canted wings for additional lift and stability. Unlike its distant predecessor, the Space Shuttle, the Ranger uses a novel aerodynamic control system that relies on RCS thrusters and electrically powered air jets to provide pitch, yaw, and roll control. This effectively eliminates a variety of moving parts such as flaps, ailerons, elevators, and rudders which would otherwise increase weight and mechanical complexity.
