Time flies, the sun and the moon are like shuttles, 2021 is coming to an end, and it is about to usher in a new year of 2022, and China's aerospace industry, which has tens of thousands of astronauts, is about to open a new chapter.
Many people are saying that 2021 is China's "space year", so what has China's aerospace discovered in the past year?
In this year, China's aerospace can be said to have opened up full horsepower, suddenly created a number of world firsts, filled a number of aerospace gaps, the three major technologies focused on the global gaze, so that many foreigners can not believe it, China is not a developing country, is not poor and backward, how can it have such advanced spaceflight? Even the United States, which has always been proud, has begun to envy.
In this year, China Aerospace has come up with three major aerospace technologies that prove China's strength, and there have been many discoveries.
Lunar exploration technology: Yutu 2, which is traveling on the back of the mysterious moon, has made a number of major new discoveries. Fire detection technology: The Zhu Rong rover, which walked on the surface of Mars, sent back several extraordinary photos of the Martian landscape. Space station technology: Known as the tall Chinese space station, even American astronauts expressed envy.
Discoveries on the Moon
In the past year, Yutu 2 has continued to move forward on the far side of the moon, continue to explore, and is designed to live for three months, but in fact, it has been driving on the moon in an extremely harsh environment for two years, and it is still in good condition and can continue to drive.
The return time of chang'e 5 lunar samples is 2020, not 2021, but Yutu 2 still has a number of new discoveries in this year.
First, Yutu 2 found a granular material in the crater, which was obviously different from the color of the lunar soil around the impact crater, so it was analyzed on the spot, and the particulate matter appeared in the hyperspectral image with blued spectral characteristics, which was indeed different.
Particulate matter and carbonaceous chondrite meteorite spectral characteristics compared, the similarity is very high, determined that it is a carbonaceous chondrite, Chinese scientists restored the formation process of carbonaceous chonds in the lunar impact crater, 1 million years ago, a carbonaceous chondrite meteorite hit the moon, so the carbonaceous chondrite remained at the bottom of the crater.
Second, in December 2021, Yutu 2 worked hard to climb the largest steep slope since driving on the back of the moon, standing on the steep slope the field of vision became very open, before entering the deep sleep, Yutu 2 looked around for 4 weeks, and found that there was an object similar to a "palace" not far in front of it, with a straight-line distance of about 80 meters.
Is it the mythical and legendary "Guanghan Palace"? In order to determine whether it is really a palace, Jade Rabbit 2 plans to spend half a year to approach this mysterious object, even if it is not a palace, it is an extraordinary moon rock with high research value.
Discoveries on Mars
In 2021, the Zhurong rover successfully drove on the barren surface of Mars, China sat firmly in the second chair of exploration of Mars, which is the news that everyone already knows, Zhu rong while driving, while taking pictures, while also transmitting a number of extraordinary Mars photos back.
Zhu Rong made a new discovery shortly after driving on the utopian plains of Mars, and took pictures that the American rover had not taken, and the photos showed a piece of Mars rock with a green substance similar to mold, which may make people a little excited, because mold is also a living organism.
But in fact, the green matter on the rocks of Mars is not mold, but only a rock color, like the colorful rocks on Earth, because it contains various minerals, such as compounds containing iron are shown red, and compounds containing copper are shown green. The green on the Martian rocks may be compounds of copper.
In November 2021, the Zhurong rover, in collaboration with international cooperation, tried to communicate with the European Aeronautical Agency's Mars Express probe, which has now been successful.
The reason why Zhurong wants to communicate with the Mars Express is to add a layer of security protection to the Zhurong, once the Tianwen 1 probe fails, then zhurong can maintain communication with the European Mars Express and will not lose contact.
The Chinese space station technology that makes the United States envious
In fact, the most envious of the Americans is the Chinese space station that lifted off this year, whether it is a technical comparison, or a comfort comparison, the Chinese space station is better than the International Space Station, although the Chinese space station is not as large as the Tonnage of the International Space Station, but the Chinese space station is really to be described as "short and small".
The Chinese space station adopts a modular structure, each module has a standard size regulation, clean and tidy, while the International Space Station does not use a modular structure, everywhere is a mess of cables and equipment, looking at it makes people's scalps tingle.
Half of the cabin of the International Space Station is built by the United States, the other half of the cabin is built by Russia, the two countries have two different design styles, and there are also incompatibilities in the power supply and interface, so the comfort of the Chinese space station is definitely higher than that of the International Space Station.
The Chinese space station also uses a technology that is not available on the International Space Station, the latest Hall electric push technology, Hall electric push is the world's lowest energy consumption of an engine system, 4 Hall electric push engines can reduce the energy consumption of the space station to the minimum.
end
In the year of 2021, China's aerospace has done a lot of space events, there are a number of new discoveries, Yutu 2 on the far side of the moon found extraordinary material, and determined the composition of the material, Zhu Rong not only landed safely on Mars, but also took photos that the American rover did not take, and we also launched an advanced Chinese space station.
In short, the three major technologies of lunar exploration technology, exploration technology and Chinese space station focus on the global vision, even Americans are envious, which has greatly affected our country, relying on these three major technologies, there will be more new discoveries in the future.
