// ORBITAL LOGISTICS AND PROPULSION TERM
Orbit Insertion
The critical maneuver where a spacecraft uses its engines to enter a stable orbit around a celestial body after traveling through space.
TECHNICAL DEFINITION
Orbit Insertion is a propulsive maneuver executed by a spacecraft to establish a stable orbit around a target celestial body, typically involving a significant delta-v burn to reduce velocity relative to the escape velocity and achieve a closed trajectory.
BACKGROUND
China has one of the most active space programs in the world. With launch vehicles of the Long March rocket family and four spaceports, China conducts the most or second most orbital launches each year. China's fleet of over 1,300 Earth orbit satellites serves communication, navigation, reconnaissance and scientific research. China Manned Space Program operates Tiangong, one of two active space stations alongside the International Space Station (ISS). China National Space Administration (CNSA) has achieved robotic rover, lander, and orbiter missions to the Moon and Mars.
