They have to build the station, check the various equipment, but also conduct scientific experiments, especially by providing valuable information about how their body fits this long term. The astronauts will also do two or three astronauts.

Term registration

Their stay doubles the time record for Chinese manned missions set in September by Shenzhou-12, the previous mission astronauts who stayed in Tianhe for three months. “The reason for this prolonged stay is to gain experience in long-term tasks“, Explains to AFP Eric Seedhouse, a professor of aerospace operations at Embry-Riddle University in Aeronautics, USA.”The main difficulty for astronauts is maintaining their muscle mass and minimizing their bone loss.“In a weightless environment that weakens organisms, he insists.

The new group will include two men: Joy Jigang (55), the first Chinese to undertake an additional vehicle excursion in 2008, and Yeh Guangfu (41), its first astronaut.

Robot and GPS

The other two modules that will make up the station, Mengtian and Ventian (laboratories) will be launched next year and will stop in Tianhe. They make it possible to carry out experiments in biotechnology, medicine or astronomy. Cooperation between the United States, Russia, Canada, Europe and Japan – China’s ambition to build a station on the International Space Station (ISS) was triggered by the US refusal to accept the Chinese people.

For its part, the Chinese space agency promised on Thursday that unmanned aerial vehicles (CMSA) foreign astronauts could fly back to Tianjang. China has been investing billions of euros for decades and catching up with other space powers. In May, it became the second country after the United States to build a small robot on Mars. China also landed a machine far from the moon in early 2019 – the first in the world.

Last year, it brought back lunar models and finalized its navigation system, Bedouin, to compete with US GPS. It launched its first solar observation satellite into orbit around Earth on Thursday. Looking ahead, Beijing plans to build a base with Russia to send humans to the moon (c. 2030).
