Tiangong-1 and Tiangong-2 were designed to verify technologies for larger 20-metric-ton modules for the planned Chinese Space Station (CSS).
Tiangong-2 raised its orbit from approximately 292 by 297 km to a current orbit of 378 by 387 km.
Tiangong-2 successfully completed its engineering and science objectives in 2017 following refueling tests with the Tianzhou-1 cargo craft.
Tiangong-2 is a more advanced version of the Tiangong-1 space lab launched in 2011.
Tiangong-2 is 10.4 m long and hosted astronauts Jing Haipeng and Chen Dong for most of the 33-day Shenzhou-11 mission.
Tiangong-2 was launched in September 2016 to test advanced life support and refueling and resupply capabilities via Shenzhou-11 and Tianzhou-1 missions in preparation for a large modular space station.
POLAR-2 involves a consortium of organizations from Switzerland, Poland, Germany and China and will seek to detect gamma-ray burst polarimetry following a first experiment aboard the Tiangong-2 space lab.
Tiangong-2 is an 8.6-ton space lab that tested advanced life support with the two-crew Shenzhou-11 mission in 2016 and on-orbit refueling and resupply with the Tianzhou-1 cargo spacecraft in 2017.
Tiangong-2 was launched in September 2016 to test advanced life support and refueling and resupply capabilities.
Tiangong-2 and Tiangong-1 were designed as stepping stones for developing and verifying technologies for 20-metric-ton modules for the planned Chinese Space Station.
Tiangong-2 docked with Shenzhou-11 in late 2016 and hosted two astronauts for 30 days, representing China’s longest human spaceflight mission to that date.
Tianzhou-1 visited Tiangong-2 in 2017 to test and verify on-orbit refueling capabilities.
Shenzhou-11 conducted a crewed mission to Tiangong-2 to test life support systems.
Tianzhou-1 conducted an uncrewed cargo mission to Tiangong-2 to test refueling capabilities in microgravity.
POLAR, a gamma-ray burst detector carried on Tiangong-2 and developed by an international collaboration including Swiss, Chinese, and Polish institutes, stopped functioning fully on 2017-04-01 due to power failure.
