The Shenzhou-11 spacecraft separated from Tiangong-2 on Thursday after astronauts completed their work aboard the space lab in preparation for their return to Earth.
The separation occured at 04:21 universal time (12:41 Beijing time) on Thursday, after Jing Haipeng and Chen Dong recovered experimental data and set up conditions for leaving Tiangong.
The Shenzhou-11 return capsule will take the astronauts back into the Earth's atmosphere and to the Siziwang Banner grassland landing zone in Inner Mongola
shortly after 05:33 UTC on Friday.
Jing and Chen will return to Earth with memory cards containing large data sets, vegetables grown in space, silkworm cocoons, astronaut urine and saliva samples, as well as sampled microorganisms for analysis.
Before the separation, the astronauts extended their thanks and respect to their ground team and to everyone who had supported China's space program, Xinhua reported.
Jing Haipeng, now 50, and Chen Dong, 37, have spent over 30 days in space, more than doubling China's human spaceflight mission duration record.
China's president Xi Jinping congratulated the astronauts on their work in a live
phone call to the Tiangong-2 space lab last week.

The pair were sent into orbit on a Long March 2F rocket from the Jiuquan Satellite Launch Centre on October 17.
The astronauts entered Tiangong-2 on October 19 after an
automatic rendezvous and docking between the space lab and their Shenzhou-11 spacecraft.

Reluctance and happiness
Speaking to Xinhua on
Wednesday, Chen said of his first space mission that he feels a bit reluctant to depart but also happy and thrilled.
"I feel reluctant because soon we will be leaving Tiangong-2, where we have lived and worked for 30 days. It is like our home in space so I still have a sense of reluctance and attachment.
"I feel happy and thrilled because we are getting back to our "big family" soon, back to our Earth, and back to our motherland," Chen said.
Chen Xin, vice director of Astronaut Centre of China, explained that once back in Beijing, the astronauts will be aided in their recovery and re-adapting to Earth's gravity.
"We will make a full evaluation on the astronauts based on their physical and mental state," Chen said.
Tiangong-2 to continue vital work
While Tiangong-2 has been vacated and unlikely to be visited again by astronauts, it will next year be part of another mission crucial for China’s space station plans.
In order to refuel and supply the future
Chinese Space Station, China has developed a Tianzhou cargo vessel, similar in purpose to Russia's Progress, America's Dragon and Cynus spacecraft, and the Japanese H-II Transfer Vehicle.
Tianzhou-1 will be launched in April on a
Long March 7 from Wenchang, before docking with Tiangong-2 and testing refuelling techniques required in order for the future CSS to maintain its orbit.

Backgrounder: China's Tiangong-2 space lab
China’s Tiangong-2 is an orbital space lab that will host astronauts and represents a crucial stepping stone to a permanently crewed space station.

Tianzhou-1 will also carry its own science payloads, including a cell bioreactor for differentiation of mammal stem cells in microgravity, a two-phase fluid instrument for spacecraft fluid management, and an electrostatic levitation accelerometer.
Tiangong-2, which could remain in orbit for five years or more, will also continue a range of
science missions. These include a thale cress experiment to study seed-to-seed growth in microgravity, and the international
POLAR gamma-ray burst detector.
