Hong Kong astronaut launched into space on China's Shenzhou-23 mission

A Hong Kong astronaut has been launched into space for the first time, aboard China's Shenzhou-23 spacecraft.

Li Jiaying, a 43-year-old police officer and mother of three, serves as the payload scientist in the three-member crew who made their way to China's Tiangong space station on Sunday night.

At least one member of the crew will spend a full year in orbit as part of a key experiment. Authorities will determine who that will be at a later date.

The mission is the latest in China's ambitious space program to send humans to the moon by 2030. It comes amid an accelerating race with the US, which is looking to achieve a crewed lunar landing by 2028.

The Shenzhou-23 is tasked with studying the effects of microgravity on the human body, among many experiments.

Apart from Li, the two other astronauts on the mission are Zhu Yangzhu, a 39-year-old space engineer and Zhang Zhiyuan, a former air force pilot, 39-year-old former air force pilot.

Large crowds waved Chinese flags as the rocket launched from the north-west Gobi desert on the Long March 2-F rocket at 23:08 local (15:08 GMT) Sunday. A few hours later, it docked on the Tiangong space station.

Li said she was inspired by Yang Liwei, the first person sent to space by China's space programme.

"This is a rare chance. Why not try?" Li said, according to Xinhua news agency.

The year-long stay will be among the longest in history, just shy of the 14-month record set by a Russian cosmonaut Valery Polyakov in 1995.

"A year in orbit pushes both hardware and humans into a different operational regime compared with the shorter Shenzhou missions of the programme's earlier phases," Richard de Grijs, an astrophysicist and professor at Macquarie University in Australia, told AFP news agency.

This shows how China is building its expertise in long stays in space as well as deep space exploration, de Grijs said.
