Docking between Tianzhou-2 and Tianhe occurred eight hours later at 21:01 UTC.
16th June 2021: The final crew for Shenzhou 12 was revealed. The commander is Nie Haisheng (3rd flight). Liu Boming (2nd flight) and Yang Hongbo (1st flight) are mission engineers.
17th June 2021: The first manned mission Shenzhou 12 to China’s Space Station was launched on 17th June 2021 at 01:22 UTC. It is China’s first manned mission after a gap of five years. The approach to the Tianhe module was with 6.5 hours very fast. Docking occurred 7:54 UTC and the Crew entered the Tianhe module at 10:48 UTC.
4th July 2021: Liu Boming and Yang Hongbo went for the first time outside of the Chinese Space Station Tiangong. The left the space station via the EVA (Extra Vehicular Activity, “spacewalk”) hatch at the Tianhe module. It was China’s second EVA in history and was 6h and 46 minutes long. The main tasks was to test the new EVA suits, using the robotic arm during EVAs and to check a external video camera.
20th August 2021: The second spacewalk (EVA) at China’s Space Station performed by Taigonauts Nie Haisheng & Liu Boming today in the morning lasted 5 hours 55 minutes and was a success. Next highlight will be the landing of Shenzhou-12 crew next month.
15th September 2021: The Long March 7 rocket with Tianzhou-3, the second cargo mission to the Chinese Space Station, arrived at the launch pad at Wenchang Space Port. It is expected that the launch will occur at 20th September around 07:00 UTC.
16th September 2021: In the morning Chinese manned spacecraft Shenzhou 12 undocked at 00:56 UTC from the Chinese Space Station Tiangong and moved close to the nadir port of the station to simulate a docking maneuver planned for upcoming manned mission Shenzhou 13.
17th September 2021: Shenzhou 12 landed around 5:30 UTC in the Gobi desert north-east of Jiuquan in China. Chinese astronauts Nie Haisheng, Liu Boming and Tang Hongbo spent 90 days on China’s first modulare space station. The next manned mission on Shenzhou 13 is expected to launch in mid-October.
18th September 2021: The Tianzhou-2 spacecraft moved from the aft port at 2:25 UTC to the front port of Tianhe. The cargo spacecraft will transfer fuel to the space station.
20th September 2021: The Tianzhou-3 spacecraft was launched at 7:10 UTC from Wenchang Space Port in China. It will deliver additional equipment, propellant and food to the new China Space Station. Docking occurred as planned at 14:16 UTC at Tianhe’s aft docking port.
25th September 2021: The Ion thrusters of Tianhe core module was fired to test the thrusters and to increase the orbit of the space station.
15th October 2021: The launch of Shenzhou 13 occured on 15th October at 16:23 UTC. Docking happend 22:55 UTC at the same day. The spacecraft docked at the nadir (earth-facing) port of Tianhe. The crew is the backup crew of Shenzhou 12: Zhai Zhigang (翟志刚), Wang Yaping (王亚平) and Ye Guangfu (叶光富). Shenzhou 12 crew will spend over 6 months on the Chinese space station Tiangong and it is the first long-duration crew in China’s spaceflight history.
7th November 2021: The first spacewalk during Shenzhou-13 was performed by Zhai Zhigang and Wang Yaping. It was the first time in history that a Chinese female taikonaut carried out an EVA. The spacewalk was 6h 25m long.
26th December 2021: Ye Guangfu and Zhai Zhigang performed a second spacewalk during mission Shenzhou-13. Both Taikonauts spent 6h 11m on this EVA. Their tasks was to install a panoramic camera, move different science payloads outside of Tianhe.
15th April 2022: The Shenzhou-13 spacecraft with all taikonauts on board undocked from Tianhe at 16:44 UTC. The Shenzhou landed around 10 hours later at 16 April 2022, 01:56:49 UTC in Inner Mongolia, China. The Crew spend over 180 days in space. That is a Chinese record. It was Wang Yaping second spaceflight and she is holding now the Chinese record for the longest stay in space with 197 days.
9th May 2022: The cargo spacecraft Tianzhou-4 was launched 17:56 UTC from Wenchang Satellite Launch Center on top of a Long March 7 rocket. The spacecraft docked at Tianhe’s aft port just under 6 hours after liftoff (10th May 00:54 UTC). The payload of Tianzhou-4 is 6,000 kg of fuel, food and equipment for the upcoming Shenzhou-14 mission.
29th May 2022: The roll-out of the Long March 2F rocket for the Chinese manned Shenzhou-14 mission to the launch site LA-4/SLS was carried out. The crew of Shenzhou-14 is still unclear.
2nd June 2022: The crew for Shenzhou-14 mission was revealed. The crew of Shenzhou-14 will be Cheng Dong (2nd flight), Liu Yang (was 1st woman in space and it is her 2nd flight) and Cai Xuzhe (1st flight).
5th June 2022: Shenzhou-14 was launched on top of a Long March 2F rocket from Jiuquan Space Center at 02:44 UTC. The docking with the Chinese Space Station at the nadir port of Tianhe happend seven hours later at 07:42 UTC. During the six-month-stay of the crew of Shenzhou-14 three spacewalks are planned and two new modules will be docked with Tianhe core module.
24th July 2022: The Wentian (Quest for the Heavens) module – the first of two science modules – was launched on the Long March 5B rocket from Wenchang Space Launch Site on 24th July 2022 at 6:22 UTC. The rollout of the rocket Long March 5B Y3 to the launch pad occurred – six days before – on 18th July 2022. Less then 13 hours after launch in Wenchang the Wentian science module docked at the Tianggong space station to the forward docking port of Tianhe module.
25th July 2022: The crew of Shenzhou-14 opened the hatches between Tianhe and Wentian for the first time and inspected the inside of the new science module.
1st September 2022: The first space walk was performed by Chen Dong and Liu Yang through airlock of the new science module Wentian. The spacewalk lasted for 6 hours and 7 minutes.
17th September 2022: Just close to two weeks later the taikonauts Chen Dong and Cai Xuzhe performed another space walk through the airlock of the science module Wentian to outfit the outside of the new module and the robotic arm with additional equipment.
30 September 2022: The Wentian science module has a small Lyappa arm to move itself to another docking port. This arm was used on this day to move from the forward port of Tianhe to the starboard port of the same module. This enabled the Chinese Space Station Tiangong to give way to the arrival of the second science module Mengtian at the forward port later this year.
31st October 2022: The Mengtian (Dreaming of Heavens) module – the second of two science modules was launched on the Long March 5B rocket from Wenchang Space Launch Site on 31st October 2022 at 7:37 UTC. Rollout of the rocket Long March 5B Y3 to the launch pad occurred on 26th October 2022.
Just around 13 hours after launch the Mengtian docked automatically at the forward port of the Tianhe core module at 31st October 20:27 UTC.
3rd November: After the Mengtian module was moved from the forward docking port to the port docking port of Tianhe the Chinese modular space station Tiangong is completed. A free-flying space telescope will be launched in 2023 and will be flying close to the space station. It will be docked only temporary to the space station for maintenance work.
9th November: Tianzhou-4 undocked from China’s Modular Space Station Tiangong at 6:55 UTC. The cargo ship is making place for the upcoming Tianzhou-5 mission which will be launched at 12th November 2022.
12th November: The Tianzhou-5 cargo mission was launched on 12th November 02:03 UTC to China’s modular space station. The spacecraft was on top of a Long March 7 rocket and lifted off from the space port Wenchang in China. The flight to the Chinese space station was a flight for the history books: In just 2 hours and 7 minutes after launch the Tianzhou-5 cargo spacecraft docked with Tiangong. This is 56 minutes (!) faster then the flight of Soyuz MS-17 in October 2020 to the International Space Station. The cargo spacecraft delievered fuel, food and equipment for the upcoming Shenzhou-15 mission to the space station.
29th November: The launch of the manned Shenzhou spacecraft with Fei Junlong, Deng Qingming and Zhang Lu on board took place on a Long March 2F at 15:08 UTC at Jiuquan Cosmodrome in China. After docking with the space station at 21:42 UTC, about 6,5 hours after launch, the Chinese space station hosts six Chinese astronauts for the first time.
