Three Chinese astronauts working at the country's space station have returned safely to Earth, state media reported on Sunday, hailing the mission as a "complete success".

The return capsule of the Shenzhou-15 spaceship touched down at a landing site in northern China's Inner Mongolia region, state news agency Xinhua reported.

Astronauts Fei Junlong, Deng Qingming and Zhang Lu emerged from the capsule in "good physical condition," according to Xinhua.

"The mission... was a complete success," it expressed.

Footage showed medical officials in white jumpsuits and face masks wrapping the astronauts in blue blankets and carrying them away from the landing site.

The trio had spent six months at the Tiangong space station, conducting spacewalks and a variety of scientific experiments.

China last week sent three more astronauts -- including its first civilian in orbit -- to the space station as part of the successor Shenzhou-16 mission.

Notably, China has invested billions of dollars in its space program, aiming to eventually send humans to the Moon.

Beijing is planning to construct a base on the Moon and the country's National Space Administration revealed that it aspires to send a crewed lunar mission by the year 2029.
