X-37B to conduct novel space manoeuvre
October 14, 2024
The X-37B Orbital Test Vehicle (OTV-7) will soon conduct a series of novel manoeuvres, known as aerobraking, in order to change its orbit around Earth and safely dispose of its service module components in accordance with recognized standards for space debris mitigation.
The use of this aerobraking manoeuvre – a series of passes using the drag of Earth’s atmosphere – will allow the spacecraft to change orbit while expending minimal fuel. Once the aerobrake manoeuvre 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.
This is the first time the U.S. Space Force and the X-37B have attempted to carry out this dynamic aerobraking manoeuvre, after six successful and safe missions, as well as decades of general lessons learned from the scientific community conducting Moon and Mars missions.
Chief of Space Operations Gen. Chance Saltzman said: “This ‘first of a kind’ manoeuvre 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.”
Secretary of the Air Force Frank Kendall added: “This novel and efficient series of manoeuvres demonstrates the Space Force’s commitment to achieving groundbreaking innovation as it conducts national security missions in space.”
The Air Force Rapid Capabilities Office (AFRCO) has managed the X-37B program since 2010, advancing the next generation of reusable space capabilities for the United States Space Force. The X-37B has been conducting radiation effect experiments and testing Space Domain Awareness technologies in a Highly Elliptical Orbit since December 28, 2023.
