The Fort Worth Press - China's Shenzhou-18 mission takes off bound for space station

The crew took off on a spaceship on top of a Long March-2F rocket from the Jiuquan Satellite Launch Center in China's northwest at 8:59 pm local time (1259 GMT).

The mission is led by Ye Guangfu, a fighter pilot and astronaut who was previously part of the Shenzhou-13 crew in 2021.

He is joined by astronauts Li Cong and Li Guangsu, who are heading into space for the first time.

They plan to stay at the Tiangong space station for six months.

While there they plan to carry out experiments "in the fields of basic physics in microgravity, space material science, space life science, space medicine and space technology", the China Manned Space Agency has said.

They will also try and create an aquarium onboard and seek to raise fish in zero gravity, state news agency Xinhua said.

"Not only will the taikonauts find joy in the space 'aquarium,' but it may also pave the way for their future counterparts to enjoy nutritious fish from their own in-orbit harvests," Xinhua said.

They will also conduct experiments on "fruit flies and mice," a researcher quoted by the agency said.

The new crew will replace the Shenzhou-17 team, who were sent to the station in October.

Plans for China's "space dream" have been put into overdrive under President Xi Jinping.

The world's second-largest economy has pumped billions of dollars into its military-run space programme in an effort to catch up with the United States and Russia.

Beijing also aims to send a crewed mission to the Moon by 2030, and plans to build a base on the lunar surface.

China has been effectively excluded from the International Space Station since 2011, when the United States banned NASA from engaging with the country -- pushing Beijing to develop its own orbital outpost.

That orbital outpost is the Tiangong, which means "heavenly palace" -- the crown jewel of a space programme that has landed robotic rovers on Mars and the Moon, and made China the third country to independently put humans in orbit.

It is constantly crewed by rotating teams of three astronauts, with construction completed in 2022.

The Tiangong is expected to remain in low Earth orbit at between 400 and 450 kilometres (250 and 280 miles) above the planet for at least 10 years.
