The three astronauts Nie Haisheng, Liu Boming, and Tang Hongbo kept making "little moves" in the cabin. Tang Hongbo "played with a pen" to experience the state of weightlessness on the spot. He also looked out the window from time to time. , compared to the "OK" gesture. Nie Haisheng also waved to the camera with a smile.

On the occasion of the 100th anniversary of the founding of the Party, and at the critical moment of the decisive battle in the construction of the space station, the Shenzhou team once again set off a wave of cheers from the people across the country with a firm victory, and this has attracted worldwide attention. The remarkable new victory was achieved by the Shenzhou people after nearly thirty years of hard work, forging ahead, and climbing up step by step.

On September 21, 1992, my country’s “three-step” development strategy for manned spaceflight was approved. From 1999 to 2002, my country's Shenzhou 1, 2, 3, and 4 were successfully launched one after another. By testing four unmanned missions, they laid a solid foundation for subsequent manned missions.

On October 15, 2003, the Shenzhou V manned spacecraft was successfully launched with an astronaut on board. It circled the earth 14 times and returned safely to the ground. my country independently and completely mastered manned space technology;

On October 12, 2005, the Shenzhou-6 manned spacecraft carried two astronauts to space and completed a number of operations in orbit. It was the first real space flight test with human participation, with multiple people and multiple days. The sky survey was successful and the first step of the project was successfully achieved;

On November 1, 2011, the Shenzhou 8 spacecraft successfully carried out the first unmanned rendezvous and docking, achieving This major leap forward in the development of my country's space technology is another new victory achieved by the Chinese people in their journey to climb the world's technological peak;

On June 16, 2012, the Shenzhou-9 manned spacecraft once again flew with Tiangong. The docking was successful twice through automatic control and manual control. Astronauts Jing Haipeng and Liu Wang, as well as China's first female astronaut Liu Yang, settled in Tiangong-1, breaking through the manual rendezvous and docking technology;

On June 11, 2013, the Shenzhou 10 manned spacecraft conducted its second manned rendezvous and docking flight. Astronauts Nie Haisheng, Zhang Xiaoguang and Wang Yaping entered Tiangong 1 after successfully completing the rendezvous and docking;

On October 17, 2016, the Shenzhou-11 manned spacecraft docked with the Tiangong-2 to form a combination. Jing Haipeng and Chen Dong performed the longest 30-day combination residency mission in my country to date, and assessed With mid-term residency support capabilities, it has carried out a series of space science and application tasks that reflect the international scientific frontiers and high-tech development directions.

Today, the Shenzhou-12 manned spacecraft mission has been successfully launched, laying a good start for the space station construction mission of manned spacecraft to and from space, and promoting my country's three-step manned spaceflight career to move forward. A solid step forward. Great dreams all start with dreams, are based on innovation, and are achieved through hard work. It is precisely because of such a group of hard-working, fearless and dedicated teams that the manned space industry has been able to achieve consecutive victories, gradually achieve technological breakthroughs and accumulation, and finally realize the complete success of the Shenzhou 12 manned spacecraft launch mission!

Gathering "skill points" for traveling between heaven and earth

The Shenzhou 12 manned spacecraft is the Chinese space station The first manned spacecraft in the mission phase is also the manned spacecraft with the highest standards and the most stringent requirements in all aspects developed by China so far.

According to the scheduled plan, the Shenzhou 12 spacecraft will adopt an autonomous rapid rendezvous and docking mode to dock with the forward docking port of the space station's Tianhe core module to form a combination. The three astronauts will stay in space for about Return to the ground after 90 days.

"Shenzhou 12 is the most complete and complete spacecraft to date. From a visual point of view, it has fully achieved the development goals of the manned spacecraft at the beginning of the manned space project." Said Gao Xu, deputy chief designer of the overall design department of the Shenzhou-12 manned spacecraft system of the Fifth Institute of China Aerospace Science and Technology Corporation. From the moment he entered the launch site, he was looking forward to launch day.

Gao Xu introduced that the Shenzhou 12 spacecraft consists of an orbital module, a return module and a propulsion module. The entire ship has 14 subsystems. It is the "ship of life" for astronauts to travel between heaven and earth. . The orbital module is equipped with astronauts’ on-orbit life support equipment, rendezvous and docking sensors and other key equipment, fully preparing for autonomous rapid rendezvous and docking; the return capsule is the section where the astronauts ride during the launch and return of the spacecraft, and is the core of the spacecraft. The "brain"; the propulsion module is equipped with a propulsion system, power supply and other equipment to provide power for the spacecraft and control the attitude orbit during flight.

In fact, the leap-forward development of the Shenzhou manned spacecraft was not achieved in one step. Since the "three-step" development strategy of China's manned space project was established on September 21, 1992, the Shenzhou manned spacecraft has passed one It has been verified again, and the success of one shot after another continues to accumulate experience and technology.

Shenzhou 1 to Shenzhou 4 achieved unmanned verification of a round trip between space and earth. Shenzhou 5 carried astronaut Yang Liwei to achieve a manned round trip. Shenzhou 6 realized a multi-person, multi-day round trip. Shenzhou 7 Shenzhou 8 and Shenzhou 10 achieved breakthroughs in unmanned rendezvous and docking and manned rendezvous and docking, and Shenzhou 11 realized the mid-term residence of astronauts.

Today, the Shenzhou 12 spacecraft has been successfully launched, laying a good start for the space station construction mission of manned spacecraft to and from space. At this point, Shenzhou 12 has collected all the "skill points" required for all missions and all modes to travel between heaven and earth.

Set five "China's firsts"

In this world-famous mission, Shenzhou 12 The manned spacecraft has reached a new level in China's manned space technology, and has completed five "Chinese firsts", namely the first time to realize the manned autonomous rapid docking with the Tianhe core module, the first time to conduct a radial rendezvous with the space station, and the first time to have The ability to return to the Dongfeng landing site from orbits at different altitudes enables the first long-term docking of a manned spacecraft in orbit, and for the first time has the emergency rescue capability with multiple guarantees of combining space and ground.

For the first time, the Shenzhou-12 manned spacecraft will implement autonomous rapid docking. With the cooperation of the space station's continuous adjustment of its posture, the Shenzhou-12 manned spacecraft can dock with the space station as soon as 6.5 hours after launch. . In addition, the Shenzhou-12 spacecraft will achieve long-term docking of a manned spacecraft in orbit for the first time, and the spacecraft will dock in orbit for three months.

Experts from the Fifth Academy of the China Aerospace Science and Technology Corporation introduced that before Shenzhou 12, the Shenzhou manned spacecraft returned to the earth from a fixed orbit. In order to save propellant consumption during the space station mission, the orbital position of the space station would change accordingly. Adjustments will be made at different time points to meet the requirements of long-term docking. For this reason, the Shenzhou team redesigned the adaptive design of the return orbit, adjusted the return height of the manned spacecraft from a fixed value to a relative range, and improved the return algorithm to improve the return adaptability and reliability of the manned spacecraft, making the Shenzhou spacecraft capable of returning from The ability to return to the Dongfeng landing site from different altitude orbits.

“In manned spaceflight, human lives matter” has always been the creed in the hearts of the Shenzhou team. In order to ensure that both the sky and the ground have the ability to protect the lives of astronauts and pick up astronauts under emergency conditions, the Shenzhou team created an emergency rescue mission model that combines space and ground, that is, bringing two spacecrafts into the field, with one spacecraft serving as the launch vehicle Backup, as a life-saving boat for astronauts in case of emergencies. The Shenzhou team adopts a "rolling standby" strategy. When the previous manned spacecraft is launched, the latter manned spacecraft will be on standby at the launch site. It has an 8.5-day emergency launch capability to achieve space rescue and fully protect the lives of astronauts. Safety.
