Universe dominance

The terrain of the northern hemisphere of Mars is very flat, and it can be said to be a very vast plain. According to scientists' speculation, the history of the formation of this landform in the northern hemisphere is not too long.

The surface of Mars is full of red gravel and finer red sand, all of which are formed by iron oxide and cover the entire surface of Mars. So when you look at Mars from space, Mars is a red planet.

Here, on a wide plain, a spacecraft fell from the sky. The huge parachute slowed down with the help of the air, and at the same time, the tail ejected flames to reduce the speed, and landed very smoothly on the surface of Mars. This is an unmanned exploration spacecraft, as soon as it landed on Mars.

At its tail, the mechanical door slowly opened, and an engineering vehicle slowly drove out of the spacecraft and stepped on the soil of Mars. It began to walk around and look around like a curious baby, knocking on stones and digging soil from time to time, collecting samples one by one.

"Hum!"

A mechanical arm on the engineering vehicle made a mechanical roar, and a drill-like thing was seen drilling down into the soil, preparing to dig out deep soil or rocks for better research on Mars.

Samples were collected back to the spacecraft. Some of these samples were rocks and soil on Mars, some were samples obtained from the deep soil of Mars through drilling, and there were also air on Mars, etc. In short, various samples about Mars were collected back to the spacecraft.

"Boom!"

The landing spacecraft spewed out flames to blow away the surrounding soil, sand and gravel, and for a while, the dust was flying, as if a big storm had blown up.

The unmanned spacecraft slowly took off, then faster and faster, and soon disappeared in the atmosphere of Mars and came to outer space, and then slowly approached the "Ocean" spacecraft, preparing to send the various samples just collected to the scientists on the spacecraft for research.

As unmanned landing spacecrafts continue to return, samples collected from various regions and locations on Mars are slowly gathered on the "Ocean" spacecraft. Scientists are extremely busy. On the one hand, they need to analyze the samples that have been collected, and on the other hand, they need to prepare for the next manned landing.

"Principal, this Mars is really barren. From the information collected from various regions of Mars, the resources contained on Mars are even less than those on the moon."

Li Quanjiang handed an analysis report to Li Fu. This data was obtained by scientists after analyzing the samples collected from various regions of Mars. Compared with continuing to detect in space, it is much more accurate.

The main elements of Martian soil are oxygen, which accounts for about 50%, silicon is 15-30%, iron is 15-16%, aluminum is 2-7%, calcium is 3-8%, and a small amount of potassium, phosphorus, sulfur, chlorine, tantalum, chromium, magnesium, cobalt, nickel, copper, etc.

The sulfur content (2.6-3.1%) is 1-2 orders of magnitude higher than the average content of the earth's crust, and the potassium content is less than 0.25%. The content of rubidium, strontium, yttrium and zirconium is much lower than that of most terrestrial igneous rocks.

The chemical composition of Martian soil is characterized by high iron, moderate magnesium, calcium and sulfur, and low aluminum. Its chemical composition does not represent the composition of the original rock, and is likely to be the product of various chemical and weathering effects of mafic igneous rocks.

According to the calculation of mineral composition, Martian soil is a mixture of 80% iron-rich clay, about 10% magnesium sulfate, about 5% carbonate and about 5% iron oxide. The mineral composition of this mixture is equivalent to 59.1% nontronite, 21.7% montmorillonite, 11.8% kieserite, 1% rock salt, about 0.5% TiO2 and 5.9% calcite.

"It's really barren. There are no scarce resources. There are still a lot of He3 on the moon!" Li Fu looked at the data from beginning to end. They are all very common elements. There is nothing worth paying attention to.

"So the moon is a gift from the universe to mankind!" Chen Bin on the side also smiled and said.

"But these are all soil data on the surface of Mars. To truly explore the distribution of minerals on Mars, we still need to dig deeper. Get ready. Arrange people to land on Mars tomorrow and dig up some deeper soil and rocks."

"No matter how big the planet is, I don't believe that we can't find some rare resources." Li Fu muttered while giving orders.

"Li Fu, major, major discovery, major discovery!"

At this time, Li Fu's teacher Liu Yi floated over excitedly. He seemed very excited, dancing with joy, and his tone was a little incoherent when he spoke.

"What's wrong, teacher?"

Li Fu asked in surprise as soon as he heard it.

"Haha, I just analyzed the ice, rock, and soil samples collected from the north and south poles of Mars. What did you find?"

Liu Yi was so happy that he came out this time to find extraterrestrial life, and the discovery when analyzing the samples just now made him ecstatic.

"You found extraterrestrial life?"

Liu Yi asked in surprise.

"No, but it will be soon."

Liu Yi's words were a bit confusing, and Liu Shiying at the side couldn't help but say: "Old Liu, what did you find? Tell me now, why are you keeping me in suspense? What you said is incomprehensible."

"Haha, I found amino acids. Although they are very, very rare, I still found them. Amino acids, do you know what this means?"

Liu Yi grabbed Liu Shiying's shoulders and looked very excited.

"Amino acids?"

When Li Fu heard this, he couldn't help but raise his eyebrows. As a scientist majoring in biology, Li Fu certainly knew what amino acids were. If amino acids are really discovered on Mars, then there is only one possibility. There are indeed microorganisms on Mars, because there is only one source of amino acids, and that is microorganisms.

"Is there really something on Mars?"

Li Fu couldn't help but murmur.

"What? Is there really extraterrestrial life?"

When Liu Shiying heard this, he became even more excited and his eyes widened. It was really unbelievable that extraterrestrial life can really be found on Mars. If extraterrestrial life can be found on Mars, that means Life should be widespread in the universe, and the earth is definitely not the only planet with life in the universe.

"I can't draw a conclusion yet, but the possibility is very high. I would like more data, and it would be best to have sample information from the deep layers of the Antarctic and Antarctic ice caps. I think there may be liquid water in the deepest layers of the Antarctic and Antarctic ice caps. There will definitely be important discoveries inside.”

Liu Yi had a smile on his face, and he looked very eager, as if he couldn't wait.
