X-37B Spaceplane to Test Innovative Aerobraking Maneuver

The U.S. Space Force's experimental X-37B is set to perform aerobraking to alter its orbit and reduce fuel consumption.

The X-37B spaceplane, launched in December 2023, will use Earth's atmospheric drag to adjust its orbit in a fuel-efficient maneuver known as aerobraking.
This mission marks the first time aerobraking is being used for an Earth orbit mission by the Space Force, although the technique has been applied in planetary missions before.
The aerobraking maneuver will allow the X-37B to safely dispose of its service module, aligning with space debris mitigation protocols.
The spaceplane's mission includes testing radiation effects and space domain awareness technologies while operating in a highly elliptical orbit.
The X-37B's maneuvers reflect the Space Force's strategic focus on enhancing mobility and adaptability in space operations.
