China succeeds at first resupply spacecraft docking

Engineers helping to assemble the Tianzhou-1 robotic space cargo vessel.
On Thursday April 19, China took another step toward its goal of permanent Chinese presence in Earth Orbit, with the launch of a Long March 7 from the Wenchang Space Launch Center. Atop the rocket as the Tianzhou-1, China's first robotic resupply spacecraft. Looking very similar to the standard shape of international space cargo ships such as Cygnus, Japan's H-2, ESA's ATV, the Tianzhou-1 was set on an orbital approach to rendezvous with the Tiangong-2 space station.

 The spacecraft rendezvoused with the station and docked successfully on Saturday the 22nd. With the main objective completed, engineers will study the combined craft operations and testing for two months. After that, Tianzhou-1 will undock and then begin a three-month period of orbital testing. Like many other cargo spacecraft, Tianzhou-1 is not designed to safely land back on Earth, but will eventually be de-orbited and burned up in the atmospheric re-entry.
