Another cargo spacecraft is set to join the core module of China's space station.

Tianzhou-3 cargo spacecraft will be launched atop Long March-7 Y4 carrier rocket at around 3 p.m. BJT on Monday, according to the China Manned Space Engineering Office.

China concluded its Shenzhou-12 manned mission on September 17 as the three Chinese astronauts, or taikonauts, in the return capsule landed safely in the predetermined area on Earth with the highest accuracy the nation had on record.

On September 18, Tianzhou-2, the predecessor of Tianzhou-3, separated with the space station's core module, conducted a fly-around and docked with the space station core module's front-facing port.

China's space station, presently a combination of a core module and cargo spacecraft Tianzhou-2, is poised to welcome incoming visitors, including manned spaceship Shenzhou-13, which is expected to be launched in October.
