Tianzhou 1 (Chinese: 天舟一号) was the debut mission of the Tianzhou-class uncrewed cargo spacecraft. It was developed as part of the crewed space program of China. Tianzhou means "heavenly vessel" in Chinese.[1] On 20 April 2017, Tianzhou 1 was launched by rocket Long March 7 at China Wenchang Spacecraft Launch Site. It successfully docked with the Tiangong-2 space laboratory on 22 April 2017 at 12:16 (UTC+8).[2] Tianzhou 1 was deorbited on 22 September 2017. It plunged into Earth's atmosphere and burned up after a set of braking maneuvers under ground control.[3]
Tianzhou 1 launched successfully on 20 April 2017 at 7:41 pm local time, from the Wenchang space center. This marked the second time a Long March 7 had been used and the first time for a mission. Tianzhou-1 became the heaviest Chinese spacecraft ever launched, at that time.[4]
Missionedit
This mission demonstrated the Tianzhou spacecraft and its capabilities. It critically demonstrated propellant transfer for the Chinese space station, the last big hurdle for long-duration expeditions.[5] On April 22, 2017, Tianzhou 1 successfully docked with Tiangong 2 marking the first successful docking of a cargo vessel, and refuelling, with the orbiting space laboratory.[6] It subsequently performed a second docking and refueling on June 15, 2017. After it coupled with Tiangong 2 for a period of 60 days, it decoupled and separated from the space laboratory and completed a three-month period of free flight at around 390 kilometres above the Earth, separately carrying out a range of science experiments. On September 12, 2017, Tianzhou 1 performed the third and final docking and refuel with Tiangong 2, with what is termed a fast docking which took 6.5 hours to complete.[7] Previously the rendezvous and docking process took around two days, or 30 orbits.[8]
