After a year of exploring Mars, what did Zhu Rong find? Green matter has been found on rocks

As the first intelligent machine zhurong rover on the mainland to explore the martian ground, it is naturally a matter of concern to the Chinese people, as long as there is no news of the Zhurong rover for a month, there will be netizens asking in the article message every three to five minutes: How is the Zhurong rover now, how many meters have it traveled, and what have been found?

Recently, 240 million kilometers away from Mars sent back a heavy news, that is, the Zhurong Mars rover is about to turn into a dormant state on its own, indicating that there is a problem with the power supply, one is that the utopian plain has entered the winter, the light has declined, and the second is that there has been sand and dust weather, and the power of the solar wing has dropped sharply.

Before officially turning into "dormancy", the Zhurong rover traveled 1921 meters in a southerly direction, less than 2 kilometers, compared with the American Perseverance rover that landed on Mars in the same period, the 1921 meter distance is really nothing, because the Perseverance has traveled nearly 11 kilometers, which is more than 5 times the distance traveled by the Zhurong Mars rover.

So in the field of exploring Mars, we also have to learn from the Americans, which is indeed the strength of the Americans, Zhu Rong Mars rover and Tianwen-1 orbiter also obtained 940G of scientific data, including Mars photos, Mars meteorological data, Mars terrain data and rock material composition analysis data.

Since landing on Mars on May 15, 2021, Zhu Rong has been exploring Mars for almost a year, and the Zhu Rong rover has many interesting new discoveries, some of which are still not discovered by the American Mars rover Opportunity and Perseverance, no wonder nasa administrations are saying that China wants to disclose Zhu Rong and Tianwen-1 data.

In June 2021, Zhu Rong, who had just spent more than 40 Martian days, made an extraordinary discovery, finding that there was a big hole in the shadow under the landing platform, how could the landing platform land on a big hole, is this not an extremely dangerous thing? What if I "roll over"?

This is actually when the landing platform lands on the surface of Mars, thousands of N thrust thrusters will blow a large hole in the soft Martian soil, which also shows that the Martian soil is completely different from the Earth's soil, which has been confirmed by the Us Insight Mars rover, and the "Mole" drilling instrument has never been able to drill into the surface of Mars.

Previously, the Zhurong Mars rover walked down on the landing platform, and for the first time listened to many special sounds, the friction sound of the metal wheels of the Zhurong Mars rover and the ramp of the landing platform, the friction of the metal wheels driving on the surface of Mars, it sounds very special, this is also an extraordinary discovery.

Zhu Rong's rover has a more extraordinary discovery, in July 2021, it found an extraordinary rock on the road slowly heading south, why say it is extraordinary? According to Mars photos taken by the Zhu Rong rover, the corner of the rock has green material.

This is the American Perseverance and Curiosity rover did not find, some people say that the green material in the corner part of the rock looks like "moldy" food, growing "green mold", I believe everyone has seen it, but the rover has not found any life on Mars, so mold is unlikely to exist.

So what is the green matter on the corner of the rock? There should be two possibilities here, one may be that the corner part of the rock contains a lot of copper, exposed in the thin Martian air copper element has been oxidized, to know that the Martian atmosphere is about 100% of the concentration of the Earth's atmosphere, but also contains oxygen.

Billions of years ago, the ancient Martian environment was more similar to the Earth's environment, there was a large amount of liquid water, forming an ocean covering most of the surface of Mars, it was simply a vast ocean, this is because at that time there was wind, rain, thunder, electricity in Mars, rivers and lakes are supplying water to the ocean.

Ancient Mars also has a relatively dense atmosphere, and the density of the Earth's atmosphere may be relatively close, there is a lot of oxygen, even if the Martian climate completely collapsed, Mars still has a thin atmosphere, or there is a certain amount of oxygen, iron oxide copper and other metal elements are possible.

Another possibility is that the Mars photos taken by the Zhu Rong Mars rover camera are distorted, if the film photos are more familiar with the fact that sometimes there will be distortion when coloring, there are some obviously abnormal colors, then this photo may be distorted when automatically coloring, which is entirely possible.

Zhu Rong Mars rover is about to turn into "dormancy", Zhu Rong's discovery has also been temporarily shelved, Mars a winter of nearly 6 months, so, Zhu Rong Mars rover this time "dormant" is a bit long, up to several months, until the end of the winter in the northern hemisphere of Mars, the light is enhanced, Zhu Rong Mars rover will wake up on its own.

Some photos show that the Solar Panel of Zhu Rong is covered with a layer of dust, which must have a certain impact on the power-making ability, and the viscosity of Martian dust is stronger than that of Earth dust, and it is more difficult to remove it completely, which is why the American Courage and Opportunity have lost contact.

However, the Zhurong Mars rover has long had a way to deal with the "dust covered solar panel", according to NASA's previous experience in dealing with Martian dust, it can blow off a lot of dust through wind, and it can also flip the solar panel to make a lot of dust fall through gravity, so we don't have to worry too much.
