The orbiter-returner of China s Chang e-5 probe has entered the moon-Earth transfer orbit after completing two orbital maneuvers, China National Space Administration (CNSA) announced on Sunday.
At about 230 kilometers from the lunar surface, the orbiter and returner fired four engines and shot into the moon-Earth transfer orbit at 9:51 a.m. BJT.
After about 22 minutes, engines shut down as the orbiter-returner successfully entered the assigned orbit.
The moon-Earth transfer orbit, also known as the Hohmann Transfer, is a fuel-efficient path allowing spacecrafts transferring between orbits by using fuels as little as possible.
The combined orbiter and returner vehicles now has escaped the lunar gravity and set it on a path toward Earth.
