Hong Kong: China’s Shenzhou-19 crew spacecraft landed in the northern country on Wednesday, state TV station CCTV reported after a one-day delay due to the weather conditions at the landing site.

The spacecraft and its three crew were sent out into space last October to work on China’s “Tiangong” permanently inhabited space station.

Shenzhou crew of space flights has been a regular fixture in the country’s space program for the past two decades and has increased in frequency in recent years after China officially ended “Tiangong” in November 2022.

The rapid development of China’s manned and unmanned space program has troubled the United States that have encountered problems with its own crew.

China aims to achieve a manned landing on the moon by 2030.

The Shenzhou-19 herd consisted of two male astronauts aged 48 and 34 and China’s third female astronaut, 35 years. It was the first aerospace for the two younger astronauts.

All part of the Chinese Military Air Force has conducted the herd experiments, some related to the construction of human habitats.

One of these experiments was expected to involve the postponement of bricks made from simulated moonlands to conditions in space.

If the tests turn out to be successful, the bricks could be a key material used in the construction of a permanent lunar research station that China hopes to be completed by 2035.

Shenzhou missions have involved trios of astronauts and six-month stay in space, with an overlap period of several days, with the departure crew handing over the station to the newly arrived group.
