June 10 (UPI) -- China is positioning a satellite to test its ability to refuel another in orbit over Earth and extend its mission for several more years.
China's Shijian-25 satellite is designed to refuel and service other satellites while they stay in geostationary orbit over Earth, SpaceNews reported.
A geostationary orbit is one in which a satellite or another spacecraft maintains its location over a particular point on Earth by orbiting at a speed that matches the planet's rotation.
The satellites were positioned more than 900 miles from each other in low-Earth orbit on Monday.
