Tianhe

China on May 29 successfully launched an automated cargo resupply spacecraft, Tianzhou-2 from Wenchang Space Launch Center in the southern islands of Hainan. The spacecraft, said to autonomously dock with key module Tianhe, will supply necessities to astronauts and propellant to maintain the orbital altitude. China's three-module space station is set to rival the International Space Station backed by the United States, Russia and Japan.
