China Aerospace 2020: sampling from the moon and landing on Mars

 China Aerospace 2020: sampling from the moon and landing on Mars

On December 27, 2019, the Long March 5 yaosan launch vehicle was successfully launched, and China Aerospaces 2019 is a perfect ending.

After super 2018, China Aerospace will usher in a record breaking super 2020.

2019 is a year of connecting the past with the future, and a dream year for Chinese astronauts to strive to run.

Lets go back to 2019 and look forward to 2020.

Brave the deep space

On January 3, 2019, change-4 probe realized the first landing on the back of the moon in human history. After landing on the moon in 1969, the lunar exploration finally opened a new page written by the Chinese.

Yutu-2 lunar rover broke the world record of 49 years held by the Soviet Union lunar rover-1 and became the longest working lunar surface inspector in human history.

At the end of 2020, the third movement of Chinas trilogy of circling the moon and returning to the earth will be played. Change-5 probe will go to Guanghan palace to carry out the first moon sampling and returning mission since 1976.

In addition to bringing back more than 2 kg of lunar soil and rock samples, change-5 will also verify key technologies such as lunar surface rise, lunar orbit rendezvous and docking. These key technologies will become a solid foundation and strong guarantee for Chinas manned lunar landing in the future.

November 14, 2019, the comprehensive test site for the landing of extraterrestrial objects in Huailai, Hebei Province.

Tens of meters high steel tower, hanging a rather sci-fi style test platform, simulates the Mars environment equivalent to 0.376 times the earths gravity.

Here, the hover obstacle avoidance test of Chinese Mars Lander is successfully carried out. The test simulates the hover, obstacle avoidance and slow speed descent process of the lander in Mars environment, and comprehensively verifies the correctness of its design.

This is the first public appearance of Chinas Mars exploration mission.

Ten years ago, Chinas Mars exploration began with international cooperation. As a passenger of Russias Forbes soil probe, the small satellite firefly-1 plans to fly to Mars for exploration.

However, there were unexpected events. In November 2011, after the launch of the Forbes soil probe, the mission failed. Chinas first Mars mission attempt, before embarking on the journey, ended abruptly.

We should control our destiny in our own hands.

Therefore, the Chinese peoples own trip to Mars will start in 2020.

In a short period of time, China Aerospace has come up with a leap forward plan: circling, landing and patrolling, one plan and one completion.

The first Mars mission adopted a complex and highly comprehensive design, which is unique in the history of Mars exploration in the world. We need to achieve the progress of other countries in decades.

However, thanks to a large amount of technology accumulation of Change project and manned space flight, this scheme is not rootless duckweed, but practical.

Risks exist all the time, and the back of risks is endless opportunities.

In order to catch up with the pioneers, Chinese astronauts are willing to take strange risks. Chinas Mars probe has entered the tiger cave and dragon pond independently, and in 2020, it will fly to the legendary red planet.

I wish the red flag could be displayed all over the world, even the fiery sea and sword mountain would rush forward.

Go ahead! China Aerospace!

Despite the long-term international blockade, Chinas aerospace industry still shows the responsibility of a major Aerospace country through practical actions.

On June 5, 2019, Chinas first sea launch was a complete success.

Within the Tropic of cancer, nearly half of the worlds population is concentrated in the tropics, but the economic development lags behind for a long time, and the level of aerospace development is generally low.

With the launch of the Long March 11 rocket at sea, the tropical countries can obtain special satellites for their own use at a lower price, so as to boost national development with space technology.

On December 20, 2019, China successfully launched a small satellite donated to Ethiopia, ending the countrys history of no satellite.

For Ethiopia suffering from natural disasters, this small satellite not only means that they can achieve disaster prevention and mitigation by means of space remote sensing, but also means that Ethiopia has the first batch of space science and technology workers. Ethiopian experts trained by China can independently control and use the satellite.

The Western powers went to Africa for killing and pestilence.

The Chinese people sent railways and satellites to Africa.

We are serious about helping our friends.

Space is not out of reach. Space is closely related to our life.

In 2019, gaofen-6 satellite will be put into operation. As a high-resolution earth observation satellite with unique skills such as super wide imaging and red edge band detection, gaofen-6 and gaofen-1, which were launched in advance, have successfully realized the networking operation. Two satellites can realize the revisit and observation of Chinas land area, greatly improving the acquisition scale and data timeliness of Chinas remote sensing data.

On November 4, 2019, at the 2019 meeting of the group on earth observations (GEO), Chinas Space Administration launched the cnsa-geo platform for high-resolution satellite 16 m data sharing service of Chinas National Space Administration, which officially announced the opening and sharing of Chinas high-resolution 16 m data to the outside world.

As long as you log in to cnsa-geo platform (www.cnsageo. Com), researchers all over the world can obtain the 16 meter satellite data with high scores from China.

This is an important contribution made by China Aerospace to the sustainable development of all mankind. It is an important measure to deal with climate change and disaster prevention and mitigation. It is also a response to the one belt and one road initiative to implement the United Nations Sustainable Development Agenda in 2030 and to build Chinas wisdom and China plan to build a community of human destiny.

In 2020, the launch of the second environmental disaster reduction satellite will be a major focus in the space field.

As one of Chinas four major satellite series, environmental disaster reduction series satellites have been playing a huge role in environmental monitoring, disaster prevention and control. Since the launch of edr-1 in 2008, it has been running stably in orbit. As a duty satellite of UN-SPIDER and International Charter on space and major disasters, environmental disaster reduction-1 still provides data for the world nearly 12 years later, setting a new record for the life of low earth orbit satellites in China.

Compared with the previous generation, the performance of EDR-2 satellite has achieved a huge leap. Many key technical indicators are not doubled, not doubled, but at least one order of magnitude.

After its launch, EDR-2 will also continue the mission of Chinese satellites such as edr-1, perform the duty task of the International Charter on disaster reduction, and offer the first-time assistance from China to the people suffering from disasters all over the world.

By the way, in 2020, Beidou satellite navigation system, beidou-3 system, will be fully built. In 2019, Galileo system was damaged due to ground fault, so it can not be fully recovered. The completion of Beidou system can provide more accurate and reliable global navigation and positioning services for users all over the world. From now on, no matter where you go, Beidou will always be with you.

On December 27, 2019, after 908 days of hard work, the launch of Long March 5 yaosan carrier rocket finally achieved a complete success.

This is 908 days of suffering, this is 908 days of hardship.

As the source and core of Chinas new generation launch vehicle, the application of new technologies on Long March 5 has exceeded 90%.

High thrust LOX liquid hydrogen engine, staged combustion cycle LOX kerosene engine Everything is new.

Difficulties came as scheduled.

On July 2, 2017, the launch of the long march No. 5 tele2 rocket failed, and the fault was located on yf-77, a high thrust liquid oxygen liquid hydrogen engine at the core level.

Scientists seem to have found the crux of the matter, and the work of returning the fault to zero has been completed.

But in the next two years, yf-77 seemed to be possessed, and the experiment succeeded and went wrong again.

The tangle of the long march V is intertwined with other events such as the failure of the remote sensing 33 satellite launched by the long march 4C, which is magnified infinitely in the Internet communication. Not only the research and development team of Long March 5, but also the whole China aerospace industry is facing great doubts.

Is our development path wrong?

If you look at the level of scientific and technological development before the space age of the United States and the Soviet Union, look at the crazy investment of the United States and the Soviet Union in the cold war, and look at the poor and white new China and the annual space budget that is not as small as that of the United States.

Then think about how much Chinas space flight has been catching up with in less than 70 years.

I believe that every Chinese will have a steelyard in their heart.

The rising place of dongfanghong-1 satellite

One is to score 750 points on the basis of 600 points, and the other is to score 700 points from less than 200 points.

The development path of Chinas aerospace industry can definitely stand the test.

Lets not be arrogant about what we have achieved, but lets not belittle ourselves.

Failure is not terrible. Whats terrible is that you cant face failure correctly. Whats terrible is that you cant grow up from failure.

We are not afraid of burning, we are not afraid of white heat, we are not afraid of the long way ahead, we are not afraid of the road block and long.

Strive for perfection, there is no risk. Photo source: China Aerospace news

In 2020, Long March 5 will undertake major missions such as the Mars probe and change-5.

In 2020, the long march 5B carrier rocket for low earth orbit launch is about to fly for the first time, and Chinas new generation of manned spacecraft will be tested in this launch.

In 2020, the first flight of the new generation of Long March VII class a multiple launch vehicles will be realized.

Only through the pain of Phoenix Nirvana can phoenix dance be gorgeous.

Seize the day, do not lose the time, Chinese astronauts have been trying to run.

Super 2020 is coming.

We are ready.
