China to send first astronaut to space station with Shenzhou-12



HELSINKI — China launched a Long March 2F rocket on Wednesday in preparation for launching the Shenzhou-12 spacecraft. and 3 astronauts to the orbiting space station module.

The Long March 2F rocket is moved vertically to the launch platform at the Jiuquan Satellite Launch Center in the Gobi Desert. The China Aerospace Engineering Agency (CMSEO) announced Wednesday.

The rocket will send Shenzhou-12 and three astronauts to the Tianhe main module for the Chinese space station, which Released April 28 Eastern region.

Officials have not released the planned launch date or the credentials of the core and backup teams for the Shenzhou-1

2 mission. The launch is expected around June 10 Beijing time. But it was delayed for a week to launch the launch. Tianzhou-2 cargo mission Should postpone the date back in a similar period

The Shenzhou-12 mission will involve a series of technical inspection tasks related to the performance and functionality of Tianhe’s core modules. It will include off-road activities using the EVA unit delivered by Tianzhou-2 and assisted inspections. reborn life

Shenzhou-12 will be the country’s first mission in more than four and a half years and only the seventh overall. China’s first mission was Shenzhou-5 in 2003, which made China only the third country to demonstrate the capability of autonomous human spaceflight.

The mission will see for the first time since May 2000 where two orbiting space stations will be inhabited simultaneously when STS-101 and Soyuz TM-30 visit the ISS and Mir respectively. Three Shenzhou flights to the Tiangong-sized Space Laboratory. Small took place in 2012, 2013 and 2016, which coincided with the ISS’s permanent habitat as a step-up mission to a large space station module.

Shenzhou-12 will set a record for China’s human spaceflight mission duration. The mission is expected to remain docked with Tianhe until September. This means that the approximately three-month mission will exceed the 33-day record set by Shenzhou-11 in 2016.

The Long March 2F and Shenzhou spacecraft were developed to enable human spaceflight after the approval of “Program 921” in 1992. The plan also sets out a long-term vision for a fully-automated space station. fragment

The 62-meter, 464-metric-ton Long March 2F consists of two stages and four side boosters, all using a highly toxic propellant of hydrazine and nitrogen tetroxide. The launcher features an escape system at the top of the fairing which relies on a solid rocket motor.

Tianhe, with a length of 16.6 meters and a diameter of 4.2 meters, will provide life support and primary habitat for astronauts. including propulsion to maintain orbital altitude

Chinese space station construction

Shenzhou-12 will be the third of 11 missions planned for the three-module Chinese space station construction phase in 2021 and 2022.

The Tianzhou-3 cargo spacecraft and the Shenzhou-13 mission will run in September and October respectively.

The experimental module, named Wentian and Mengtian, is expected to launch in 2022. The pair will host numerous experiments in areas such as astronomy, space medicine. life science in space biotechnology Physics of fluids in microgravity burning in microgravity and space technology

International data science will fly to the space station in collaboration between the United Nations Office for Space Affairs (UNOOSA) and CMSEO. Foreign astronauts are expected to visit CSS.

Both modules will be launched by the Long March 5B rocket from Wenchang, the first phase of the Long March 5B launching Tianhe into orbit and making High profile, unregulated re-entry..

The Chinese space station is expected to operate in orbit for at least ten years. It will be joined in orbit by Xuntian optical moduleOrbiting Hubble Space Telescope The space telescope will have an aperture of 2 meters, comparable to Hubble. but has 300 times more field of view

This view would allow Xuntian to survey 40 percent of the sky over a decade using a 2.5 billion pixel camera.
