China's Tianzhou-3 cargo spacecraft docked with the country's space station's core module Tianhe at 10:08 pm on Monday, 6.5 hours after its launch, according to the China Manned Space Engineering Office.

The cargo ship docked onto Tianhe's backward facing port using the automatic fast docking process.

With the Tianzhou-3 docked and Shenzhou-12 headed back to Earth, the space station still consists of three parts: the Tianhe core module, the Tianzhou-2 and the Tianzhou-3.

Tianzhou-3 is one of the most advanced cargo spacecrafts in the world. It can carry as much as 6.9 tonnes of supplies.

This mission is part of a series of launches to build China's space station. Soon, three Chinese astronauts, or taikonauts, will board the Shenzhou-13 spacecraft and get into the space station.
