The Tianzhou (Chinese: 天舟; pinyin: Tiān Zhōu; literally: 'Heavenly Ship') is a Chinese automated cargo spacecraft developed from China's first prototype space station Tiangong-1 to resupply its modular space station. It was first launched (Tianzhou 1) on the Long March 7 rocket from Wenchang on April 20, 2017[2] and demonstrated autonomous propellant transfer (space refueling).[3][4]

The first version of Tianzhou has a mass of 13,500 kg and can carry 6,500 kg of cargo. Tianzhou-6 is the first improved version of the spacecraft to be launched into orbit; it has a mass of about 14,000 kg and can transport 7,400 kg of cargo.[5]

Function

Based on the Tiangong-1 space station, the Tianzhou functions as the main automated cargo spacecraft for the Tiangong space station. It has pressurized, semi-pressurized and unpressurized cargo capabilities, and is able to transport airtight cargo, large extravehicular payloads and experiment platforms. It was first launched on the new Long March 7 rocket from Wenchang on April 20, 2017.[3][6]

Name

The China Manned Space Engineering Office opened a consultation for the naming of the prospective cargo ship on April 25, 2011. By May 20, it had received more than 50,000 suggestions.[7] On July 8, Yang Liwei, China's first astronaut and deputy director of the Chinese Academy of Sciences revealed that they had a short list of ten names.[8] On October 31, 2013, it was revealed that the spacecraft had been named Tianzhou (Chinese: 天舟; pinyin: Tiān Zhōu; literally: 'Heavenly Boat'), combining the Chinese names of the Tiangong (Chinese: 天宫; pinyin: Tiān Gōng) space stations and the Shenzhou (Chinese: 神舟; pinyin: Shén Zhōu) spacecraft. They also stated that they would use the two letter identification TZ.[9]
