After more than nine months in an unusual, highly elliptical orbit, the US military's X-37B spaceplane will soon begin dipping its wings into Earth's atmosphere to lower its altitude before eventually coming back to Earth for a runway landing, the Space Force said Thursday.
The aerobraking maneuvers will use a series of passes through the uppermost fringes of the atmosphere to gradually reduce its speed with aerodynamic drag while expending minimal fuel. In orbital mechanics, this reduction in velocity will bring the apogee, or high point, of the X-37B's orbit closer to Earth.
Bleeding energy
The Space Force called the aerobraking a "novel space maneuver" and said its purpose was to allow the X-37B to "safely dispose of its service module components in accordance with recognized standards for space debris mitigation."
