China’s Tianzhou-1 test cargo freighter successfully completed its third docking with the prototype test space station module Tiangong-2 today.

Commands for the rendezvous and docking were issued at 17:24 Beijing time, according to the China Manned Space Agency, with the new ‘fast’ process taking 6.5 hours to complete.

Previously the rendezvous and docking process took around two days, or 30 orbits. The breakthrough will be used to allow crewed Shenzhou craft to reach the future Chinese Space Station (CSS) much sooner after launch.

Tianzhou-1 will soon perform a third and final refuelling test with Tiangong-2, before the cargo spacecraft is carefully deorbited over the South Pacific.

No word yet on when China might resume launches however. Since the July launch failure of their largest rocket, Long March 5, the country has launched nothing. There have also been stories that suggest the planned December launch of their Chang’e 5 lunar mission will be delayed now until the spring.
