China News Service, Beijing, January 20th. Title: Space station construction, fire detection, and launch times are 40+... 2021 China's aerospace is worth seeing

  Author Guo Chaokai

  On January 20th, with the Long March 3B rocket successfully sending the Tiantong One 03 satellite into the scheduled orbit, China Aerospace will have a "good start" in 2021.

Turning to this year’s "Itinerary", the space station is under construction, Tianwen-1 has landed on Mars, and the number of launches per year has exceeded 40.....China's aerospace arrangements in 2021 are full and worth seeing.

Space station starts construction

  Looking at China's space mission in 2021, the space station project is undoubtedly the top priority.

Zhou Jianping, chief designer of China's manned space project, said in an interview with the media that China will launch the core module of the space station first this spring, and then launch the Tianzhou-2 cargo spacecraft and the Shenzhou-12 manned spacecraft to complete the rendezvous and docking and related operations. Key technology verification of rail.

  According to the space station construction mission plan, China will continue to implement 11 missions this year and next, including 3 space station section launches, 4 cargo spacecraft and 4 manned spacecraft launches. The space station will be built in orbit by 2022 to realize China The mission goal of the third step of the development strategy of the human space engineering three-step development strategy.

  Recently, good news about space station missions has spread frequently.

On January 17, the China Academy of Space Technology held an expedition ceremony for the space station mission test team in Beijing.

Prior to this, the space station Tianhe core module and the Tianzhou-2 cargo spacecraft have successfully passed the factory review, which indicates that the construction of the space station is about to enter the mission implementation stage.

With the launch time approaching, the people are very much looking forward to this "Made in China" space station.

Tianwen-1 landed on Mars

  Since its launch at the Wenchang Space Launch Site on July 23, the Tianwen-1 Mars probe has been flying for nearly 6 months during the "fire detection" journey.

As of 6:00 on January 3, the flight mileage of the Tianwen-1 probe exceeded 400 million kilometers.

At present, the detector's attitude is stable, and it is expected to implement near-fire braking around February 10 and enter the ring-fire orbit.

  "Long distance" for 7 months, just for an "intimate date" with Mars.

In the field of lunar and deep space exploration, China has successfully launched five spacecraft from Chang'e-1 to Chang'e-5, achieving the three-step "round and fall" of the lunar exploration project; but Mars is still a "virgin land" that China has not yet set foot in space. .

The emergence of Tianwen No. 1 is expected to fill this gap.

  The Tianwen-1 mission has taken the first step in China's independent interplanetary exploration.

This mission, which puts the high hopes of the Chinese people, will achieve "circumnavigation, patrol" on Mars through a single launch.

Once the mission is successful, China will become the second country in the world capable of conducting fire watch inspections.

The number of launches is expected to break 40

  In recent years, China's space launch has entered a high-density launch phase, with the number of annual launches stabilizing at more than 30.

Among them, 39 times in 2018 and 34 times in 2019, ranking first in the number of launches by countries in the world for two consecutive years.

In 2020, although China launched slightly less than the United States, there were 39 launches, the same as 2018.

  This heavy transcript is inseparable from the efforts of China Aerospace Science and Technology Corporation.

Among these 39 missions, China Aerospace Science and Technology Group took the lead, contributing 34 times, accounting for 87.2% of the total launch volume.

As the core force of China's aerospace launches, China Aerospace Science and Technology Corporation recently announced an exciting news: in 2021, the group plans to arrange more than 40 aerospace launches.

If you count the aerospace missions of China Aerospace Science and Industry Corporation and aerospace private enterprises, the number of China's space launches in 2020 is expected to reach a new high.

Commercial aerospace is in full swing

  In the past 2020, China's civilian-operated rockets have made major breakthroughs.

Following the maiden flight of the Hyperbola-1 rocket in 2019, which achieved the breakthrough of zero successful entry of Chinese civilian-operated rockets into orbit, the successful maiden flight of the Ceres-1 commercial carrier rocket in 2020 will make Chinese private rockets "good things come together".

  Apart from the "national team" mission, China's commercial aerospace is also in full swing.

In recent years, rocket private companies have made steady progress in the development of reusable rockets.

The reusable rocket Hyperbolic II independently developed by Interstellar Honor plans to conduct a sub-level vertical take-off and landing test at the meter, kilometer, and hundred kilometers level in 2021.

The core components of the Suzaku-2 rocket developed by Blue Arrow Aerospace have been delivered, and the initial prototype power system test rocket and the modal arrow full rocket assembly will be carried out in the future.

  With the development of technology, low-cost mass production and networking of satellites are becoming possible.

Recently, the Space Engineering Company of the Second Academy of China Aerospace Science and Industry Corporation completed the design, production and installation of China's first batch-produced satellite intelligent production line, which can produce more than 240 small satellites per year.

While SpaceX is rapidly deploying "Starlink" satellites, China's aerospace private companies such as Galaxy Aerospace and Jiutian MSI are also stepping up their deployment of satellite Internet, aiming to solve the "Internet problems" in deserts, oceans and remote mountainous areas.

In 2021, more space forces from the private sector will continue to emerge.
