After nearly a year in orbit, the US Space Force’s X-37B is set to perform its first aerobraking maneuver during its seventh orbital test vehicle mission (OTV-7).

This technique uses atmospheric drag to slow the spacecraft and alter its orbit while conserving fuel.

The X-37B, which has extended its flight durations over its six previous missions, will also eject its service module as part of this process.

The mission includes conducting experiments related to space domain awareness and testing materials for radiation exposure, the Register has reported.

The X-37B will remain in orbit for additional experiments before eventually returning to Earth.
