In-orbit refueling test proves a success

China has successfully carried out its first in-orbit refueling test, which observers say means it can now prolong the life span of its satellites and spacecraft.

Tianyuan 1, the country's first in-orbit refueling system for satellites, was lifted into space by a Long March 7 carrier rocket on June 25 during the rocket's maiden flight.

The mission also marked the first use of China's fourth and latest space launch center in Wenchang, Hainan province.
