Three astronauts successfully docked with China's new space station on Saturday (Oct 16), state media said, on what is set to be Beijing's longest crewed mission to date and the latest landmark in its drive to become a major space power.

The three blasted off shortly after midnight local time (12am Singapore time) from the Jiuquan launch centre in northwestern China's Gobi desert, state-run news agency Xinhua said, with the team expected to spend six months at the Tiangong space station.

After the launch, the China Manned Space Agency declared it a success and said the crew members "were in good shape", according to Xinhua.

The Shenzhou-13 vessel carrying the three then docked hours later with the radial port of the space station, Xinhua said in a brief dispatch on Saturday morning.

The mission - twice as long as its 90-day predecessor - will set up equipment and test technology for future construction on the Tiangong station.

Shenzhou-13, which means "Divine Vessel" in Chinese, is the second of four crewed missions needed to complete the space station by the end of 2022.

Mission commander Zhai Zhigang, 55, a former fighter pilot who performed the country's first spacewalk in 2008, said the team would undertake "more complex" spacewalks than during previous missions.

The astronaut team includes military pilot Wang Yaping, 41, who is the first woman to visit the space station after becoming China's second woman in space in 2013.

The other team member is People's Liberation Army pilot Ye Guangfu, 41.

A previous record-breaking space crew - making the first mission to Tiangong - returned to Earth in September after three months on the space station.

China's heavily promoted space programme has already seen the nation land a rover on Mars and send probes to the moon.

Tiangong, meaning "heavenly palace", is expected to operate for at least 10 years.

Its core module entered orbit earlier this year and the completed station will be similar to the Soviet Mir station that orbited Earth from the 1980s until 2001.

The long mission is set to "expand China's technological boundary" and verify the space station system's capacity for a longer duration of human occupation, Chen Lan, an independent space analyst at GoTaikonauts, told AFP.

"I don't think it is very challenging, as China's technologies (are) quite mature, though anything in space is always challenging," Chen said.

Saturday's blast-off came shortly after China launched its first solar exploration satellite into space, equipped with a telescope to observe changes in the Sun.

The Chinese space agency is planning a total of 11 missions to Tiangong through to the end of next year, including at least two more crewed launches that will deliver two lab modules to expand the 70-tonne station.

China's space ambitions have been fuelled in part by a US ban on its astronauts on the International Space Station, a collaboration among the United States, Russia, Canada, Europe and Japan.

The ISS is due for retirement after 2024, although NASA has said it could potentially remain functional beyond 2028.

Chinese space authorities have said they are open to foreign collaboration on the space station, although the scope of that cooperation is as yet unclear.

The country has come a long way since launching its first satellite in 1970.

It put the first Chinese "taikonaut" in space in 2003 and landed the Chang'e-4 robot on the far side of the Moon in 2019 - a historic first.

China in May became the second nation to land and operate a rover on Mars.
