Half-immortal civilization

Human beings have always been full of fantasies about Mars, second only to the moon.And now, when it's about to land on Mars, everyone is excited.

Of course, space is not the ground, especially the space of other planets.Therefore, the spacecraft must orbit Mars at least three times to detect various dangers.

It's a red planet, scarred, with rift valleys, volcanoes, and more impact craters.The largest crater almost blew up the entire northern hemisphere of Mars. Compared with the ancient southern hemisphere, the northern hemisphere is very "new". Because of the violent impact, the southern hemisphere of Mars bulges and the northern hemisphere sinks. The entire northern hemisphere is melted, so the northern hemisphere is relatively Relatively flat.This is an unprecedented catastrophe. At present, only Mars can see such traces in the entire solar system.

Because life has been found on the distant Ceres, everyone is more curious about Mars; of course, the hundreds of deep pits all over the planet are also full of fantasy, and the methane ejection of thousands of cubic meters per day has attracted everyone. gaze.It's a pity that all the detectors can't get close to this place, and once they enter it, they will completely lose contact.

Of course, only Liu Haibo knows that one of the main purposes of the master company's detection is to find enough water sources!Whether it is liquid water or solid water, even water mixed with various impurities will do.The rest can only be placed in the second place.In fact, the most important thing should be to explore Venus.

Transform Venus!Every time he thought of this plan, Liu Haibo trembled a little.While others are still racking their brains to compete, the boss has already set his sights on Venus.

The spaceship is in space, "slowly" hovering in the orbit of Mars, through various cameras, detectors, etc., to take pictures of the ground of Mars clearly, and even using supercomputer technology, it has formed a A [-]D map of Mars with a diameter of two meters.

Through the powerful gamma-ray detector, it can detect the depth of at least 1000 meters on the surface of Mars. After three circles, a real three-dimensional Mars is presented in front of everyone. Not only can it distinguish every millimeter of detail surface, as well as the surface crust at a depth of thousands of meters.

"Look, this is obviously an underground river! There are also lakes!" Irregular blue spots are connected by some winding blue lines, looming and intermittent at a depth of about a thousand meters.However, with such a layout, it is very easy to think that this is underground water reservoirs, underground rivers and the like; but in fact, the earth's underground water reservoirs, underground rivers, etc. are full of life.

"Don't get excited, it doesn't have to be the groundwater space, it may be a lot of methane, etc. After all, we can only measure the existence of hydrogen in this way. In fact, there should be a lot of methane on Mars; and methane contains hydrogen The amount is higher." Liu Haibo was still a little rational, and didn't go crazy.

"Brother Liu, it's been three laps now, and basically no danger has been found. Can we land on Mars?" Su Jiuyang, the captain of the second team, was already very excited.The exploration on Ceres has already made everyone feel thrilling, rewarding, eye-opening and so on.The way of sprinting from the surface of the planet to take off into space has become an entertainment that everyone will never tire of.

"Okay. Let the boys get ready. Besides, there is an atmosphere on Mars, although the concentration is only one percent of that on Earth; but because of this, the atmosphere is so thin that the wind is very strong and fast, and the mud The sand is hovering rapidly. The strong wind mixed with a lot of dust is the best grinding tool, which can grind the space suit for a long time. Let everyone pay attention to safety.

In addition, because this time Mars is already our last stop, you will build a permanent base on Mars, and keep some of our things here for the convenience of those who come later.For example, this time we plan to use a small number of three Mars rovers, and leave these things on Mars permanently.After all, the cost of bringing it back to space from Mars is too high. "

"Well... Then, what if other countries use it?" Su Jiuyang felt a little heartbroken.

"Then let them use it. It's our little contribution." Liu Haibo didn't care, with a wicked smile on the corner of his mouth: "It will take at least 10 years for them to land on Mars. In these ten years, the master company will definitely It will develop into an existence that everyone looks up to."

"Since that's the case, then we can announce this news! Let them feel the greatness of China!" Su Jiuyang was taken aback for a moment, and then he came to his senses.

That's right, since people can't use it for ten years, then we will announce it: If you land on Mars, the permanent base left by Master Company will be opened unconditionally.This is a picture of a big pie!Of course, there are substantive moral repercussions.

"Good idea!" Liu Haibo looked at Su Jiuyang like a smart person!
Landing on Mars is different from Ceres. The ground here is all desert, and there are strong winds, gravity, etc. The gravity of Mars has reached 3.72, plus the various items carried by the astronauts, basically equivalent to a normal person on the earth. weight up.However, it is extremely difficult for people to walk on the surface of Mars due to the inconvenient movement of space suits; therefore, Mars exploration must rely on Mars rovers.

Of course, the design of the Mars rover of Gaoshou Company is not simple. It has tall tires and strong electric power; the most important thing is that it can tow the carriage.

"Listen up, all the teams, we are about to enter the stage of landing on Mars. Please prepare the first to third teams, you will set off as the advance team of the expedition. Your job is to bring the Mars rover, basic survival materials, etc., Delivered to the surface of Mars.

Followed by four to seven teams, you are responsible for building a permanent Mars underground base.The eighth to tenth teams are responsible for carrying out exploration and exploration operations. "

A large amount of materials are taken from the spaceship by the manipulator, put into the space shuttle or carried on the back.Because Mars has an atmosphere, the difficulty of landing with such a load is greatly reduced because of atmospheric resistance.Although the atmosphere is only one percent of that of the earth, the gravity of Mars is also low.

The place to land on Mars is a relatively flat sandy land—in fact, the air carries fine sand, which has already polished the surface of Mars many times. The surface of Mars is basically covered by red sand; There are only a few places such as the North and South Poles.

The space shuttle is dispatched frequently, because it is the last stop of the expedition, and everyone will leave as much as possible on the spacecraft on Mars.In particular, the geological stability of Mars makes it easier to establish a permanent underground base.In recent years, for tens of thousands of years, Mars has not suffered a major meteorite impact, which also made everyone decide to build a permanent base here.

In fact, there are at least [-] tons of materials on the spacecraft, which can be left on Mars.And these materials stay on the spacecraft, and there is not much value in returning to the earth. Expert companies can produce a large amount of these materials in a few days.In addition, carrying a large amount of materials and accelerating the spacecraft in space are all problems.All things considered, it's better not to stay at all.This kind of value is even greater, providing strong support for the next Mars landing.

It is not a small project to send tens of thousands of tons of materials to Mars via the space shuttle.Although the gravity on Mars is very low, the atmosphere is also thin, so the load of each space shuttle is still only about a hundred tons.

However, all exploration equipment, experimental equipment, Mars rovers, etc. will all remain on Mars.

The entire shipping process lasted five days.If you want to load in space and then land on Mars with a thin atmosphere, especially the extremely low temperature here, you have to take precautions, etc., which makes the whole project very slow.

"Next, let the construction team go!" Five days later, the four to seven teams, which had already had enough rest, started to set off.
