Three Chinese astronauts working on the country’s space station returned safely to Earth and hailed the mission as “a complete success”, state media reported on Sunday. The returning capsule of the Shenzhou-15 spacecraft has landed at the landing site in the Inner Mongolia region of northern China, state news agency Xinhua reported.

Xinhua reported that astronauts Fei Junlong, Deng Qingming and Zhang Lu emerged from the capsule in “physically good condition”.

The message reads “Mission… completely successful”.

The footage showed medics in white overalls and masks wrapping the astronauts in blue blankets and diverting them from the waterless landing site, where the copper-colored capsule was covered with red flags. The trio spent six months on the Tiangong Space Station conducting spacewalks and various scientific experiments.

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

The world’s second-largest economy has poured billions of dollars into the military space program in an effort to catch up with the United States and Russia. Beijing plans to send a manned mission to the moon by 2030 and plans to build a base on the moon’s surface.
