On September 10, the first year of the new human calendar, after three months of sailing, Mars was close at hand.

According to Dr. Rimbaud's deceleration scheme, the speed of the spacecraft did decrease after people threw a large amount of ore residue out of the spaceship, which shows that humans have mastered a new and efficient way to decelerate.

Don't underestimate this type of deceleration. In just a few seconds, a large amount of matter can be ejected, and the high-speed spacecraft can be reduced from 28km/s to 1km/s, which cannot be done by human technology alone.

In space, deceleration and acceleration are equally important and equally difficult.

……

Now, the Mars landing has become the most important thing for people. The observatory has become a favorite place for people to stay, because from the observatory, you can see Mars, the orange-red planet. This massive red color is romantic and spectacular in the eyes of many people.

There are many couples who like to go on a date at the observatory because this place is really nice......

In the newly built "Big Rice Bucket" cafeteria, scientists are gathering in twos and threes to discuss the landing on Mars.

Although there have been some human explorations of Mars, landing in person and looking at photos are two different experiences. Not only the general public, but also scientists are very excited.

"You see, Mars has a thin atmosphere, and the air pressure is about one percent of that of Earth. The water resources of Mars are basically concentrated in the form of ice in the polar regions, so it is better for us to land at the north and south poles of Mars. "A middle-aged scientist is looking at a photo while eating chicken fried gluten on a plate.

Nowadays, because of the taste, Chinese food has become the mainstream food for many people.

A scientist next to him frowned and said, "Water resources? You may be able to find it underground, but I think it's better to find a place with abundant uranium resources to land. Energy is king, a new batch of power stations is about to be built, with electricity, everything is available! ”

At this time, another female scientist eating pasta also said: "I also think it is better to land in a place rich in mineral resources." We have a lot of things to build, like new labs, new power plants, etc., water can be slowed down, energy first. ”

"No, you can't build a large biosphere without water." It was a biologist who was most concerned about building a large ecosystem, and there was no water, no pastures, no parks.

At this time, a scientist who had spent a lot of money to buy two small yellow croakers, after enjoying the food, suddenly became triumphant, "Anyway, no matter where we land, our Wild Wolf Design Bureau has long been ready, and it will definitely shine in this Mars operation!" ”

Another young scientist passed by, and when he heard this, he immediately blew his beard and glared at him, and said, "What is a wild wolf?" We Tesla are only ...... We've surpassed you in points! ”

"What? You're just passing it temporarily! Do you understand temporarily? We just didn't get it! ”

The wolf man was really angry, "Besides, you guys came up with that slowdown plan?" It was the ship's own, so how can you say you made it? At best, you've found out early......"

"Okay, okay, let's eat quickly, what's the noise, the academic meeting will be noisy!" The middle-aged scientist at the beginning hurriedly pulled the two of them and persuaded with a wry smile.

After two months, the wild wolf and Tesla can be said to be like fire and water, competing fiercely with each other, and they don't like each other.

In this regard, many scientists have maintained a neutral attitude and do not help each other, and they have even set up their own research institutes, and the entire spacecraft has become a pattern of "two superpowers and many powers".

"You young people, what's the use of playing tricks, the key depends on the results. Whoever deciphered all the secrets of this spaceship, I, Ding Yidong, were the first to be convinced of him! ”

At this time, Professor Ding Yidong was just about to leave, and when he heard the two people arguing, he said something faintly.

Hearing this, the rest of the scientists all fell silent, and some were still secretly smiling bitterly.

This spaceship, I really don't know if I don't study it, and it's really like a god when I study it. Because its scientific and technological content is too different from human science and technology, the current science can hardly explain it, and people can only guess blindly.

What "beyond the deceleration scheme" is just a use of some reasonable speculation, and then confirmed by experiments.

Human beings do not understand the essence of it, just like a blind man crossing a river and touching a stone. What kind of vacuum zero point can be, just give yourself an explanation, the research report is basically a blind guess, and there is no way to confirm it.

Everyone knows this, but they just barely found an explanation to comfort themselves. How did it work? I don't know......

The current human race is like being in a mountain of gold and silver, but they can't use it, and everyone is anxious. Each nugget is the size of a house, and getting one can make humanity rich. But human strength is like an ant, unable to lift a single piece of gold.

How frustrating it is for scientists to see but not understand. So, it's not uncommon to hear the roars of some physicists...... In particular, Tesla and Wolf compete with each other, but they have nothing to do with the spaceship, and they have a hot temper......

"Let's continue with the conversation." The middle-aged scientist smiled, "Personally, I think it's better to land in the North and South Poles." In such a big place as the North and South Poles, at least there is a certain amount of water, and maybe there are mineral deposits...... There is water, there is energy, there are mines, it would be nice to have a place like this."

"There must be a small number of people who will land for a scientific expedition first, and then consider the landing of the Noah."

"That's right."

……

At 2:33 p.m., the Noah spacecraft, which was in a low-speed state, was officially captured by the gravitational pull of Mars and revolved around Mars.

If Earth is a blue star, then Mars is a red star. The scenery seen from space is completely different.

As the speed decreases further, Noah even touches the atmosphere above Mars, and the surface of the spacecraft is almost non-heating because of almost no friction. However, the observation room, engine, power room and other devices mounted on the outside will still be hot and hot, but people have already made protective devices and can still use them normally.

According to expectations, Noah will float in the Martian atmosphere due to air buoyancy.

Because its density is too low, the mass of a 15-kilometer sphere is only 1.03 million tons, and its density is equivalent to 0.000073 kilograms per cubic meter! This density is much lower than a hydrogen balloon!

As a result, Noah's air buoyancy can be counteracted by gravity as long as there is a slight atmosphere, and it will float above the atmosphere. It's a miracle that the density of a large spaceship is so small, and this is technology that people can't understand.

If you want it to sink, it's as simple as loading more and heavier stuff outside the ship.

Yu Yifeng was holding a landing meeting at this time, and it had been held for a long time, and the basic plan had been formulated, so he still chose the North Pole of Mars. Because the Antarctic region has many mountains, while the Arctic is relatively flat, the terrain is more suitable.

Now only the question of personnel remains. Because people's motivation is high, even too high, everyone wants to go. Alas...... Do they think it's a tourist vacation?

A whole bunch of scientists are talking about how they want to be part of the Martian expedition.

"Dr. Roman, you should be the leader of this expedition." After pondering for a long time, Yu Yifeng directly named him. Dr. Roman, the former chief biologist at the Moon Base, has good prestige and personal abilities.

"No problem." Roman said immediately, very happy in his heart. He was still thinking about finding out if there was life on Mars, but he didn't expect that the opportunity would be available immediately.

At this moment, people are even more anxious, and a few even want to get up from their positions.

"Mr. Yu, we will definitely be able to do it!"

"Trust us!"

“…… I have experience in geological surveys! ”

Hearing this, Yu Yifeng couldn't directly hinder people's enthusiasm, so he could only shake his head and say: "That's it, the first batch of scientific expedition teams is tentatively set at five hundred, which is quite a lot." Scientists, geologists, miners, doctors, and soldiers had to have them, as well as enough food and machinery...... I'll have the Victory ship come and go a few times, and the supplies will be supplied. ”

"Everyone fills out a volunteer list first, and we will screen it as appropriate."

Hearing this news, the scientists' hearts were immediately overjoyed, five hundred people, the opportunity is not small. They assured Yu Yifeng again and again that they would definitely complete the task and report to Yunyun in time.

"You understand this survey mission, right? In the North Pole region of Mars, find a place with water, minerals, and energy as a landing site for Noah...... Also, investigate the possibility of the existence of life on Mars and eliminate potential dangers. Everybody understands, right? ”

"Understood!"
