Chinese astronauts have began their six-month mission on China's first permanent space station after successfully docking aboard their spacecraft.
The astronauts, two men and a woman, were seen floating around the module on Saturday before speaking via a live-streamed video.
The new crew includes Wang Yaping, 41, who is the first Chinese woman to board the Tiangong space station, and is expected to become China's first female spacewalker.
"We'll co-operate with each other, carefully conduct manoeuvres, and try to accomplish all tasks successfully in this round of exploration of the universe," said Wang in the video.
The space travellers' Shenzhou-13 spacecraft was launched by a Long March-2F rocket at 12.23am (0334 AEDT) on Saturday and docked with the Tianhe core module of the space station at 6.56am.
The three astronauts entered the station's core module about 10am, the China Manned Space Agency said.
They are the second crew to move into China's Tiangong space station, which was launched last April. The first crew stayed three months.
The new crew includes two veterans of space travel - Zhai Zhigang, 55, and Wang. The third member, Ye Guangfu, 41, is making his first trip to space.
The mission's launch was seen off by a military band and supporters singing Ode to the Motherland, underscoring national pride in the space program, which has advanced rapidly in recent years.
The crew will do three spacewalks to install equipment in preparation for expanding the station, assess living conditions in the Tianhe module, and conduct experiments in space medicine and other fields.
China's military-run space program plans to send multiple crews to the station over the next two years to make it fully functional.
