The crew of China's Shenzhou 16 mission captured incredible images of the Tiangong Space Station as they departed on their way back to Earth.
The pictures, taken with a high-definition camera, represent the first time the full structure of the Tiangong space station has been fully imaged since it arrived in orbit.
Prior to disembarking, the Shenzhou 16 team handed control of the space station over to the Shenzhou 17 crew, who arrived at Tiangong on Oct. 26. The three taikonauts (Chinese astronauts) consisting of commander Jing Haipeng, Zhu Yangzhu and Gui Haichao then left Tiangong on Oct. 30 in the Shenzhou 16 return capsule and arrived back from low-Earth orbit on the same day.
As they made their way toward Earth, the crew turned their cameras toward their former temporary home, capturing breathtaking views of the laboratory in orbit above Earth.
Located at 217 and 280 miles (340 to 450 kilometers) over the planet, the first unit of the Tiangong known as Tianhe arrived in low-Earth orbit in 2021. Its first crew, Shenzhou 12, arrived at the space station on June 16, 2021. They spent 90 days at the station, which was three times longer than any prior taikonaut mission.
The second and third units of the space station, Wentian and Mengtian, were launched in 2022 and 2023, respectively. This completed the 180-foot (55-meter) long station, which weighs 77 tons and is about 20% as large as the International Space Station.

Since then, Tiangong — whose name means "Heavenly Palace" — has hosted a rotating crew of three taikonauts who have performed a host of important science experiments, something the CMSA aims to maintain for at least a decade.
The crew of Tiangong 16, the fifth team to inhabit the space station, continued the scientific exploration conducted aboard the space station by conducting a spacewalk, growing vegetables, and conducting a live lecture from space during which they demonstrated lighting a match in microgravity.

The stunning Shenzhou 16 images may capture Tiangong in its full glory as it is currently, but if the CMSA gets its way, the image will soon be out of date. On Oct. 4 at the 47th International Astronautical Congress in Baku, the space agency revealed it intends to expand the space station with an extra three modules, bringing its total unit count up to six.
In addition to this, the CMSA intends to send Tiangong some company in the form of a Hubble-class space telescope called "Xuntian" that will orbit Earth alongside the space station and will be capable of meeting up with it for repairs, refueling, and even upgrading.

Shenzhou-17 astronauts conduct first spacewalk to repair solar array
HELSINKI — China’s Shenzhou-17 astronauts embarked on their first extravehicular activity Thursday to address minor damage to a Tiangong space station solar array.
Mission commander Tang Hongbo and Tang Shengjie began a roughly 7.5-hour extravehicular activity (EVA), or spacewalk, Thursday. The pair reentered Tiangong through the Wentian science module’s EVA hatch at 8:35 a.m. Eastern (1335 UTC) Dec. 21, according to the China Manned Space Engineering Office (CMSEO).
Shenzhou-17 spacewalk tasks included a repair test on one of the Tianhe core module’s solar arrays. The system was earlier found to have suffered minor damage through micrometeoroid hits.
The successful experimental repair work could be seen as a big step for China as it aims to keep its Tiangong space station operational and permanently occupied for at least a decade.
Crewmate Jiang Xinlin assisted operations from inside Tiangong through the use of the space station’s robotic arm. Tang Shengjie, 34, became China’s youngest astronaut to embark on an EVA so far.
Tang Hongbo completed his first spacewalk back in July 2021 during the Shenzhou-12 mission — the first to visit the Tianhe core module.
“This extravehicular activity is extraordinarily significant, and extremely challenging. It is an in-orbit maintenance in its true sense,” Tang Hongbo said after the spacewalk, according to CCTV.
“At that moment, being there, I deeply felt the vastness of the starry sky and the profound meaning of infinite space exploration,” Tang Hongbo said.
A highlight video released by CMSEO showed the astronauts conducting closeup examinations of the solar array, assisted by the station’s robotic arms.
The EVA posed new challenges for the astronauts, according to Dong Nengli, deputy chief designer of China’s human spaceflight program.
“For the previous extravehicular activities, the major tasks for astronauts were to install and check. This round of extravehicular activities on Thursday we call experimental servicing,” Dong told CCTV.
“This time the astronauts operated on one of the solar wings. It is flexible, to a certain extent, and also very thin, which limits the space of operation to a certain degree,” Dong said.
Dong added that the successful EVA meant the teams had mastered the ability for some extravehicular repairs. Success was thus, “laying a solid foundation for us to guarantee the space station’s safety and reliability in the future.”
The work required close coordination with the ground. “The repair work requires a very high level of precision, so it demands high precision in astronauts’ operation and proficiency in their use of tools,” Wang Yanlei, director of the astronaut selection and training department of the China Astronaut Research and Training Center, told CCTV.
“They also had to confirm the coordination between ground and space, and verify the accuracy of the position.” Wang added.
Evolving Tiangong plans
China completed construction of Tiangong in October 2022 and is further developing its plans for its utilization.
CMSEO is planning to launch an additional module which will allow the expansion of the orbital outpost. Yang Liwei, the country’s first astronaut to fly to space, says a process to select the first international astronauts to visit Tiangong is underway.
A report from the Air Force’s China Aerospace Studies Institute (CASI) earlier this year noted that how CMSEO operates Tiangong, such its opening participation to civilian astronauts and nonstate-owned enterprise (SOE) companies, could probably change the global image of the Chinese space program. CMSEO operates under China’s People’s Liberation Army (PLA).
Gui Haichao became the first Chinese civilian in space during the five-month-long Shenzhou-16 mission earlier this year.
Commercial launch firms may also get to play a role in a new low-cost cargo system to supply Tiangong. Tomas Hrozensky, a senior research fellow at the European Space Policy Institute (ESPI), told SpaceNews earlier this year that the CMSEO cargo program is a clear indication that China is seeking to replicate the approach which yielded NASA a major success.
Also Dec. 21 components for a Long March 7 rocket arrived at the coastal Wenchang spaceport. The rocket will launch the Tianzhou-7 cargo mission to Tiangong in mid January.
China's Tianzhou-6 cargo craft separates from space station combination
The Tianzhou-6 cargo craft, tasked with carrying supplies for China's space station, separated from the station combination at 4:02 p.m. Friday (Beijing Time) and switched to independent flight, according to the China Manned Space Agency (CMSA).
The cargo craft will re-enter the atmosphere in a controlled manner in the future. Most of its components will burn up and be destroyed during the process, while a small amount of debris will fall into designated safe waters in the South Pacific, the CMSA said.
Launched on May 10, 2023, Tianzhou-6 has a loading capacity reaching over 7 tonnes, making itself the world's largest cargo spacecraft in service.
According to the CMSA, last month, Tianzhou-7, the spacecraft for the country's next space cargo mission, was transported to the launch site in the southern province of Hainan. Along with its carrier rocket, the cargo craft underwent assembly and testing to gear up for the launch as planned.
