Patriotic dimension

Called Tiangong (“Heavenly Palace”), the Chinese space station, when completed, will be similar in size to the former Soviet Mir station (1986-2001). Its lifespan will be at least ten years.

China resolved to build its own space station after the United States refused to let it participate in the International Space Station (ISS). The latter – which brings together the United States, Russia, Canada, Europe and Japan – is due to retire in 2024, even though NASA has mentioned a possible extension beyond 2028.

Just before their departure, the mission commander, Nie Haisheng, accompanied by Liu Boming and Tang Hongbo, said goodbye to their relatives and colleagues in a ceremony with strong patriotic content during which an old revolutionary refrain resounded. : “No New China Without the Communist Party”.

At a press conference on Wednesday, the three astronauts sent a military salute to journalists, in front of a large red flag with five stars. Nie Haisheng, who has already carried out two space flights, underlined the patriotic dimension of the operation. “For decades, we have written glorious chapters in Chinese space history and our mission embodies the expectations of the people and the party itself.”, did he declare.

The trio underwent more than 6,000 hours of training, including tumbles in the pool in spacesuits, in order to get used to weightless rides. “We fought every minute to fulfill our space dream”, testified Liu Boming, one of the crew members. “I trained by dedicating myself to the cause. “
