Three Chinese taikonauts have returned from a mission to a new space station being built by China.

It was the first trip in a series of four planned missions to the new Chinese space structure.

The taikonauts stayed there for ninety days.

Construction of the space station began in April.

China then launched the first section of the space station, the Tianhe capsule, into orbit.

This capsule will serve as a residence for future taikonauts on the space station.

The three taikonauts, Nie Haisheng, Liu Boming, and Tang Hongbo, have stayed there throughout their journey.

During their stay, the taikonauts went on spacewalks and carried out checks on the living module.

They also tested an existing robotic arm and sorted supplies for new missions.

Over the past decade, China has worked extensively on its own space station, partly because American legislation prevented China from collaborating with NASA.

The Americans are in charge of the International Space Station, the only other space station.

The Chinese space station is expected to be completed by the end of 2022. A new manned flight from China to the station is planned for October. The taikonauts who go then stay there for six months.
