China prepares Tianzhou-2 cargo operation to pursue forthcoming space station launch

Tianzhou-2 cargo

HELSINKI — A Long March 7 missile has landed at China’s coastline Wenchang spaceport in order to accelerate the Tianzhou-2 supply mission to a quickly-to-launch space station segment. On 12th April, the release announcement is by the China Manned Space Engineering Office. It is part of extreme arrangements for building a modular space station in low Earth orbit.

China recently prepares a Long March 5B space rocket to launch Tianhe. It is approximately a 22-metric-ton spacecraft that will perform as the core space station module. That operation is likely to launch toward the end of April. The recent delivery of the Long March 7 kerosene-liquid oxygen propellant medium-lift missile is put together in order to launch the Tianzhou-2 cargo and supply spaceship to harbor with the core module.

The Tianzhou-2 goal is to provide Tianhe with the following:
  • Propellant for retaining its orbital altitude
  • Supplies for hosting astronauts
  • The cargo spacecraft has a mass of around 13,000 kilograms at lift-off
  • And cargo mass of around 6,500 kilograms

The Shenzhou-12 mission, starting on a Long March 2F missile from Jiuquan, will consequently send three astronauts for the Tianhe core segment. Chinese space agencies do not disclose a comprehensive timeline for the forthcoming missions. However, earlier launch operations for the Long March 5B and Long March 7 rockets suggest the Tianhe launch is probable to take position near late April. This is with the Tianzhou-2 mission set to go by mid-May. Shenzhou-12 possibly will launch as soon as in June.

The Long March 5B to release the core module is to roll out to the launch pad around a week in advance of the launch. The Long March 7 will roll along to a distinct pad at Wenchang around 5 days prior to its subsequent launch. China aims to build its three-module space station with 11 launches across 2021-2022. These will involve three-module releases and appointments by four crew missions and four cargo spaceships. Chinese astronauts are presently in preparation for space station exercises, along with 12 astronauts likely to fly on the four missions.

A senior official said in March, “A Long March 2F missile is also to be on back-up at Jiuquan in order to carry out alternative rescue missions to the space station.” The three-module, 66-metric-ton space station to host three astronauts for half-yearly cycles.

A schedule of experiments includes international projects in the areas such as:
  • Astronomy
  • Space medicine
  • Biotechnology
  • Microgravity fluid physics
  • Space life science
  • Microgravity combustion
  • Space technologies

The station will circle at between 340-450 kilometers for a minimum of 10 years. The orbital tendency will be around 43 degrees to permit crewed releases to the station from Jiuquan in the Gobi Desert. The station can possibly develop into six modules, using evident reserve modules.

The elements for the 53-meter-long Long March 7 deliver to Qinglan port, Hainan island, by freight vessel Xu Yang 16 following compilation from the northern port city of Tianjin. The Long March 7’s first release dates 2016, which carries a magnitude form of a return container for a new-generation crew spaceship. The 2nd mission a year later forwarded Tianzhou-1 to port with the Tiangong-2 space lab. That mission examines and verifies technologies for fuel transmission in microgravity. This is essential expertise in order to maintain a low Earth orbit space station.

China aims to commence manufacturing of the space station in 2018 or 2019. However, the collapse of the second Long March 5 rocket in July 2017 causes delays. The country is now compressing the space station production stage while retaining a 2022 goal for its completion.

The space station proposal initialized in 1992. It witnesses China become just the third country to create autonomous human spaceflight facilities. China releases six crewed missions. The first, Shenzhou-5, with an introduction in 2003, with the most recent, Shenzhou-11, taken out in 2016.
