The landing spacecraft passed through the thin atmosphere of Mars and landed in the southern hemisphere of Mars.

The leaders of the scientific expedition team are Gao Yuxi, and the other three are soldiers of the Space Force Mars Fleet.

Gao Yuxi and the others did not enter the anti-load survival chamber, mainly because the atmospheric concentration of Mars is low, and the gravity is not as strong as that of Blue Star, so the spacecraft does not need to enter the anti-load cabin when landing on the spacecraft.

Ignoring the ship's business, how to drive the spacecraft to the Greek basin was the job of the three Space Force fighters.

She's looking at Mars.

Mars is about half the diameter of Blue Star, has a volume of 15%, a mass of 11%, a surface area equivalent to the land area of Blue Star, and a much smaller density than the other three terrestrial planets in the Solar System (Blue Star, Venus, and Mercury).

In terms of radius, mass, and surface gravity, Mars is about halfway between the blue star and the Moon: Mars is about twice the diameter of the Moon and 1/2 of the Earth, and its mass is about 9 times that of the Moon and 1/9 of the Earth, and its surface gravity is about 2.5 times that of the Moon and 2/5 of the Earth.

In addition, the southern hemisphere, where the Greek basin is located, is mainly dominated by ancient mountains, plateaus, and impact craters.

The Northern Hemisphere, on the other hand, is dominated by relatively young plains.

These data did not make Gao Yuxi pay too much attention, humans detected these data in the A.D. era, and the data she really cared about was the data detected by the Diting satellite.

Using atomic-level precision data, layer by layer is modeled into an underground model of Mars.

Zhang Haiyang, a paleontologist, geologist, nuclear physicist, and science fiction writer on the side, was also watching these stratigraphic data.

He was about to say something.

[Note that the ship is about to land.] ］

The ship was slightly stunned.

[Successful landing, welcome to Mars, the 001 outpost in the Greek Basin.] ］

The 001 outpost is based on a small plain in the middle of the Greek Basin.

This base has 67 simple space capsules, 1 communication base station, 1 small Jinwu reactor, 1 neutrino radar station, 1 multi-purpose airport, 20 stand-in robots, and 240 multi-functional robots.

and, most importantly, nanobot factories.

Although Mars has an atmosphere, the atmosphere is dominated by carbon dioxide and nitrogen dioxide, which is not suitable for new humans to breathe.

So everyone is wearing astronautical exoskeleton armor.

If you don't want to wear heavy space exoskeleton armor, you can also activate the alien automatic adaptation mode in the biocomputer, which can take three days to adapt to the Martian environment.

After a series of tests, Gao Yuxi and Zhang Haiyang finally set foot on the land of Mars.

The blue sun is hanging high in the sky, and there are two satellites, one large and one small, one gray and white "potato" and one the size of a coin, which are Phobos and Deimos.

Once inside the base, all of them were disarmed.

Outpost 001 consists of two parts, the working area and the living area, with only one passage in the two areas.

Three Space Force soldiers went to check the outpost's equipment and supplies reserves, because they needed to live here for about half a year.

Gao Yuxi and Zhang Haiyang, the four of them, arranged their luggage and their respective dormitories, and came to the work area impatiently.

The outpost was already autonomous, with artificial intelligence manipulating the robot to survey and sample more than 100 kilometers around.

Inside the work area, thousands of samples collected by the robot from the surrounding area are stored.

Zhang Haiyang picked up a piece of sedimentary rock with something similar to a coral fossil on it and put it into an age detection device not far away.

[Sedimentary rocks: 3.7736~377.39 million years]

There are not a few such sedimentary rock fossils, and most of the fossils of organisms above are invertebrates.

Huang Fan, a viriologist and microbiologist on the side, was observing the rows of gel petri dishes, and the virtual display screen was displaying 54 viruses, 27 bacteria, and 3 fungi found in the outpost.

"This is a failed planet of life." Gao Yuxi put down the file and said.

Zhang Haiyang nodded: "That's true, the invertebrates and plants of Mars have completely broken after 310 million years. ”

"At least some of the microbes survived." Huang Fan said with a smile.

It's just that Zhang Haiyang, who is a science fiction writer, is frowning, and he is thinking about the reasons for the mass extinction of Martian life.

Then I thought of the gap in the Nibelon's ship.

There are too many secrets in the solar system, and the truth behind these secrets is always terrifying.

Gao Yuxi looked at Zhang Haiyang in a daze, shook his hand in front of the other party's eyes and asked, "What do you want?"

"Oh?...... Thinking about the mass extinction of life on Mars. ”

"Worried about the big filter?" Gao Yuxi obviously saw the other party's concern.

Zhang Haiyang nodded.

"You are too worried about the ocean, the big filter is of little use to the current new human beings, low-level attacks are useless, unless there is a supernova explosion near us, a black hole, a vacuum decay, or an invasion of a high-level cosmic civilization, otherwise we can deal with the past." Huang Fan said optimistically.

"If it's a mass extinction of natural factors, I'm not worried, the key is the human factor." Zhang Haiyang had a delusional idea of persecution.

"An-la! Instead of worrying about this and that, it's better to do your research on the ground. Huang Fan of the Optimist faction patted Zhang Haiyang on the shoulder.

"That's just as well."

When arranging the staffing of the expedition team, the scientific committee fully considered the personality and characteristics of each team member.

For example, Gao Yuxi, who is calm and calm, Zhang Haiyang, who has whimsical ideas but delusions of persecution, Huang Fan, who is optimistic, and Jiang Naoto, who is loyal and low-key.

Complementing each other's personalities is something that the Scientific Committee needs to consider.

……

The mass extinction event on Mars is one of the destinations of the expedition team to Mars, and another mission is to study the microorganisms of Mars.

Huang Fan used an instrument to isolate the virus strain from the culture medium and inject it into a fist-sized ball of meat.

Is the meat ball Sim? The scientific research aid developed by Baker and Linsha is called "Virus Functional Test Body", which is a cloned tissue that imitates the human body, and with the addition of biological computers and cellular robot technology, it can test the function of the virus.

In fact, it is similar to the living mice and chimpanzees used in general biological laboratories, except that the reaction of viruses and bacteria entering the meat ball is 99.99% similar to that of new humans.

After all, guinea pigs, chimpanzees and new humans are different species after all, and experimenting with real people is not only too risky, but also easy to cause unnecessary trouble.

……

The virus injected into the meat ball, designated [Mars-Greece-00024].

On the sign detector on one side, rows of data are refreshing, such as heartbeat, blood pressure, blood sugar, hormones, body temperature, acid-base, salt balance, brain waves, antibodies, and virus levels.

This is equivalent to doing human experiments directly, and the safety is very high.

[Injection for 2 hours: the degree of infection is mild, the virus is friendly to lung cells, there is no obvious tendency to attack, and it is a semiparasitic type...... ］

Huang Fan was doing experiments while sorting out the data.

The study of viruses native to Mars is very important, although the fact that new humans can now ignore the vast majority of viruses does not mean that they can arrogantly believe that the universe is invincible.

Arrogance is the biggest obstacle to survival.
