Secret Space Plane & Aerobraking
The tiny USAF/USSF unmanned space shuttle that has quietly been breaking records across seven lengthy deployments (up to 900 days on orbit per trip) since 2010, is set to perform some very next-level maneuvers.
Powered by Gallium Arsenide Solar Cells with lithium-ion batteries, the X-37 is just over nine feet tall and 29 feet long with a wingspan of just under 15 feet. For reference, the Space Shuttle Orbiter was 122 feet long and had a wingspan of 78 feet, making it several times larger.
The pint-sized X-37B Orbital Test Vehicle, as detailed by the USSF, “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.”

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.
Boeing, eager to point out they can get some stuff right when it comes to off-planet ops, has released an interesting reel including depictions of releasing payloads and some of the X-37’s declassified records.
