Tianzhou 1 (Chinese : ) was the debut mission of the Tianzhou-class unmanned cargo spacecraft. It was developed as part of the manned 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]

Chinese language family of languages

Chinese is a group of related, but in many cases not mutually intelligible, language varieties, forming the Sinitic branch of the Sino-Tibetan language family. Chinese is spoken by the ethnic Chinese majority and many minority ethnic groups in China. About 1.2 billion people speak some form of Chinese as their first language.

Tianzhou (spacecraft) spacecraft

The Tianzhou is a Chinese automated cargo spacecraft developed from China's first prototype space station Tiangong-1 to resupply its future modular space station. It was first launched on the Long March 7 rocket from Wenchang on April 20, 2017 and demonstrated autonomous propellant transfer.

Spacecraft Manned vehicle or unmanned machine designed to fly in outer space

A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle.

Spacecraft

It used the first flight model of the Tianzhou. It is a Chinese automated cargo spacecraft developed from the Tiangong-1 to resupply its future modular space station.

Tiangong-1 Chinas first space station

Tiangong-1 was China's first prototype space station. It orbited Earth from September 2011 to April 2018, serving as both a manned laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities during its two years of active operational life.

Chinese large modular space station Planned space station to be placed in Low Earth orbit

The Chinese large modular space station is a planned space station to be placed in Low Earth orbit. The planned Chinese Space Station will be roughly one-fifth the mass of the International Space Station and about the size of the decommissioned Russian Mir space station. The Chinese station is expected to have a mass between 80 and 100 tonnes. Operations will be controlled from the Beijing Aerospace Command and Control Center in China. The planned launch date of the core module, the Tianhe-1, is 2020. In 2017, the Chinese launched the Tianzhou-1 cargo spaceship, which is based on the Tiangong 1 and 2 space laboratories.

Launch

Tianzhou 1 launched successfully on 20 April 2017 at 7:41pm local time, from the Wenchang space center. This marked the second time a Long March 7 has been used, and the first one for a mission. Tianzhou-1 became the heaviest Chinese spacecraft ever launched, at that time. [4]

The Long March 7, or Chang Zheng 7 as in pinyin, abbreviated LM-7 for export or CZ-7 within China, originally Long March 2F/H or Chang Zheng 2F/H, nicknamed "Ice Arrow", is a Chinese liquid-fuelled carrier rocket of the Long March family, developed by the China Aerospace Science and Technology Corporation. It made its inaugural flight on June 25, 2016.

Mission

This mission demonstrated the Tianzhou spacecraft and its capabilities. It critically demonstrated propellant transfer for the Chinese space station, the last big hurdle for the 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]

History of spaceflight aspect of history

Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky and Robert H. Goddard. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first man and the first woman into orbit. The United States caught up with, and then passed, their Soviet rivals during the mid-1960s, landing the first man on the Moon in 1969. In the same period, France, the United Kingdom, Japan and China were concurrently developing more limited launch capabilities.
