Human beings have always been full of fantasies about Mars, second only to the moon. And now, when we are 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.
This is a red planet with scars, rift valleys, volcanoes, and more 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 was bulged and the northern hemisphere was dented. The entire northern hemisphere was melted, so the northern hemisphere is relatively new. Relatively flat. This is an unprecedented catastrophe, and such traces can only be seen on Mars in the entire solar system.
Because life has been discovered on the distant planet Ceres, everyone is even more curious about Mars; of course, the hundreds of deep craters all over the planet also fill people with fantasy. Thousands of cubic meters of methane are ejected every day, attracting everyone. gaze. Unfortunately, all detectors cannot get close to this place. Once inside, contact is completely lost.
Of course, only Liu Haibo knew that one of the main purposes of the expert company's detection was 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 second place. In fact, the most important thing is to explore Venus.
Transform Venus! Liu Haibo trembled a little every time he thought of this plan. While others are still racking their brains to compete, the boss has already set his sights on Venus.
The spacecraft "slowly" hovers in the orbit of Mars in space. Through various cameras, detectors, etc., it can clearly capture the ground of Mars. It even uses supercomputer technology to form a picture in the main control room. A three-dimensional map of Mars two meters in diameter.
Through the powerful gamma ray detector, the surface of Mars can be detected to a depth of at least 1,000 meters. After three circles, a true three-dimensional Mars is presented in front of everyone. Not only can every millimeter of detail be distinguished in detail, On the surface, there are also surface crustal conditions that are thousands of meters deep.
"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 kilometer. However, such a layout makes it easy for people to think that these are underground reservoirs, underground rivers, and the like; but in fact, there are many kinds of life in the earth's underground reservoirs, underground rivers, etc.
"Don't get excited, it's not necessarily underground water, it could be a large amount of methane, etc. After all, our method can only measure the presence of hydrogen. In fact, there should be a large amount of methane on Mars; and methane contains hydrogen The quantity is higher." Liu Haibo is still somewhat rational and is not crazy.
"Brother Liu, it has 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 excited. The exploration on Ceres has been thrilling, rewarding, eye-opening, etc. for everyone. The method of taking off from the surface of the planet by sprinting into space has become an endless entertainment activity for everyone.
"Okay. Let the boys get ready. In addition, there is an atmosphere on Mars, although the concentration is only one percent of that on Earth; but because of this, because the atmosphere is thin, the wind is extremely strong and fast, and the mud swept away The sand swirls quickly. The strong wind mixed with a lot of dust is the best grinding tool and can grind the space suit for a long time. Please pay attention to your safety.
In addition, because Mars is our last stop this time, you should establish a permanent base on Mars and leave some of our things here for later use. For example, we are planning to use three Mars rovers this time and leave them 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 can be regarded as our contribution." Liu Haibo didn't care, with an evil smile on his lips: "It will take at least 10 years until they land on Mars. In these ten years, the master company will definitely It will develop into an existence that everyone can look up to.”
"If that's the case, then we can announce the news! Let them feel the greatness of China!" Su Jiuyang was stunned for a moment, and then he came to his senses.
Yes, since it cannot be used by others within ten years, then we will announce it: if you land on Mars, the permanent base left by the Master Company will be opened unconditionally. This is a big pie! Of course, it can get substantial 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 Martian gravity has reached 3.72, plus the various items carried by the astronauts, which is basically equivalent to the weight of a normal person on Earth. Weight too. However, coupled with the inconvenience of movement in space suits, etc., it is extremely difficult for people to walk on the surface of Mars; therefore, Mars exploration must use a Mars rover.
Of course, the design of Gaoshou's Mars rover is not simple either. It has tall tires and strong electric power; the most important thing is that it can tow a carriage.
"Listen up, all teams, we are about to enter the stage of landing on Mars. Teams 1 to 3 please get ready. You will set off as the advance team of the expedition. Your job is to bring the Mars rover, basic survival supplies, etc., to Transport to the surface of Mars
Then there are teams of four to seven or four. You are responsible for building a permanent Mars underground base. The eighth to tenth teams are responsible for carrying out exploration and expedition operations. ”
A large amount of supplies were taken from the spacecraft by manipulators, put into the space shuttle or carried on the back. Because Mars has an atmosphere, the difficulty of such a weight-bearing landing is greatly reduced because of the atmospheric resistance. Although the atmosphere is only one percent that of Earth, Mars' gravity is also low.
The location chosen for landing on Mars was a relatively flat sandy land - in fact, the air carries fine sand, which has already polished the surface of Mars countless times. The surface of Mars is basically covered with red sand; There are only a few places such as the North and South Pole.
The space shuttle is frequently dispatched. Because it is the last stop of the expedition, everyone will leave as much stuff on the spacecraft as possible on Mars. In particular, the geology of Mars is stable, making it easier to establish a permanent underground base. In recent years, Mars has not been hit by major meteorites for tens of thousands of years, which has led everyone to decide to establish a permanent base here.
In fact, there are at least 10,000 tons of supplies on the spacecraft that can be left on Mars. If these materials are left on the spacecraft, they will not have much value when returned to the earth. Expert companies can produce a large number of these things in a few days. In addition, carrying a large amount of supplies and accelerating the spacecraft in space are all problems. All things considered, it would be better not to stay at all. This kind of value is even greater, providing strong support for the next Mars landing.
Sending tens of thousands of tons of materials to Mars via a space shuttle is no small project. 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 it in space and then land it on Mars, which has a thin atmosphere, especially because the temperature here is extremely low, you have to take precautions, which makes the whole project very slow. "Next, let's set off the construction team!" Five days later, teams four to seven, who had already had enough rest, began to set off.
