X-37B Begins Aerobreaking Space Maneuver

The X-37B Orbital Test Vehicle (OTV-7) will begin executing a series of novel maneuvers, called aerobraking, to change its orbit around Earth and safely dispose of its service module components in accordance with recognized standards for space debris mitigation. Since December 28, 2023, the United States Space Force, supported by the Air Force Rapid Capabilities Office, has conducted radiation effect experiments and has been testing Space Domain Awareness technologies in a Highly Elliptical Orbit.

The use of the aerobraking maneuver- a series of passes using the drag of Earth's atmosphere- enables the spacecraft to change orbits while expending minimal fuel. Once the aerobrake maneuver is complete, the X-37B will resume its test and experimentation objectives until they are accomplished, at which time the vehicle will de-orbit and execute a safe return as it has during its six previous missions.

Secretary of the Air Force Frank Kendall stated, "This novel and efficient series of maneuvers demonstrates the Space Force's commitment to achieving groundbreaking innovation as it conducts national security missions in space."

This is the first time the U.S. Space Force and the X-37B have attempted to carry out this dynamic aerobraking maneuver leveraging six successful missions of operating the space plane safely, as well as decades of general lessons learned from the scientific community conducting Moon and Mars missions.

Chief of Space Operations Gen. Chance Saltzman praised the team for its efforts. "This first of a kind maneuver from the X-37B is an incredibly important milestone for the United States Space Force as we seek to expand our aptitude and ability to perform in this challenging domain. The success is a testament to the dedication and perseverance of the team."

AFRCO has managed the X-37B program since 2010. It is dedicated to advancing the next generation of reusable space capabilities for the United States Space Force.
