The crew will stay aboard Tianhe, the first of three modules that will eventually comprise Tiangong. It launched in April and has already received one crew, who returned last month after three months on the station.

Tiangong, or «Heavenly Palace, is the third Chinese station to carry the name. It’s expected to receive the last of its modules sometime next year.

Zhai, the mission commander, has said he expects the six months of weightlessness to be the biggest hurdle for the crew, calling it «a big challenge to our physical and mental situation.

«We will, for sure, encounter some challenges in terms of physical and mental health, and also technical issues, he said.
