On December 27, 2019, the Long March 5 Yao III launch vehicle (hereinafter referred to as the "Long Wu Yao III") was ignited at the Wenchang space launch site in China and successfully launched the practice 20 satellite into its orbit. As China's first large thrust carrier rocket with a core diameter of 5 meters, the Long March V carrier rocket has the highest carrying capacity in the world. Its successful launch will undoubtedly lay a solid foundation for China Aerospace's "Super 2020".

In 2020, China will use the Long March V launch vehicle to launch the "Chang'e 5" aircraft to achieve unmanned return to the moon and successfully complete the three-step overall planning goal of the lunar exploration project. According to the introduction of Changzheng 5 Chief Commander of the First Academy of China Aerospace Science and Technology Corporation, Chang'e 5 mission needs to send more than 8 tons of Chang'e 5 detectors directly into the Earth-Moon transfer orbit. Carrying capacity of the Long March V launch vehicle.

At present, China is developing the first Mars exploration project. According to the plan, in 2020, China will launch a Mars probe through the Long March V, and realize Mars orbit, landing and patrol detection in one launch.

Mars is one of the planets in the solar system. The "Mars Sunburst" occurs about every 26 months. At this time, the distance between Mars and the Earth will reach an extremely close value. During this time, the probe can be sent at a small cost. To Mars, therefore, human exploration of Mars usually climaxes every 26 months. In 2020, there will be an opportunity for "Mars to strike the sun". After the probe is launched, it will take about 7 months to fly to Mars.

Li Dong, chief designer of the Long March 5 launch vehicle of the First Academy of China Aerospace Science and Technology Group Co., Ltd. said that the successful development of the Long March 5 will greatly improve China ’s ability to enter space and help China ’s deep space exploration capabilities and levels to be improved. A leap forward in the field of deep space exploration. "As planned, China will achieve a soft landing on Mars in 2021 and carry out Mars orbiting and patrol detection."

China's manned spaceflight project has established a three-step development strategy: the first step is to launch a manned spacecraft, build a preliminary supporting experimental manned spacecraft project, and carry out space application tests; the second step is to break through the astronaut technology Spacecraft rendezvous and docking technology to launch a space laboratory to solve space applications with a certain scale and short-term care. The third step is to build a space station to solve problems with large-scale and long-term care of space applications.

From 2003 to 2016, China sent 14 astronauts to space and sent Tiangong-1 and Tiangong-2 to the sky, which means that the first and second steps of the "three-step walk" have been successfully completed. China Aerospace is about to enter the era of the space station.

According to the China Manned Space Engineering Office, China ’s manned space station is expected to be completed around 2022. It can support the long-term presence of three astronauts and operate in orbit for 10 years. It will open cooperation with the international community and provide global shared space applications. platform.

As the main rocket for launching the core capsule of the space station in the manned space station project, Long March 5B is expected to usher in its first show in 2020, which will also accelerate the pace of China's manned space station construction.

As the rocket with the largest carrying capacity in China, the development history and successful launch of the Long March V have accumulated valuable experience for a new generation of launch vehicles, and have a fundamental and prerequisite role in the implementation of many major aerospace projects in China. In 2020, various new generation launch vehicles such as the Long March 5B, Long March 7A, and Long March 8 developed by the First Academy of China Aerospace Science and Technology Corporation will have their first flight.

Exploring the vast universe, developing the space industry, and building a space power are the space dreams we are relentlessly pursuing. The success of five years and three years has laid a solid foundation for China ’s aerospace “Super” 2020 and a solid step for building a space power.

Long March Five, Arrow of Dreams, Come on! China Aerospace, 2020, come on!
