Help all mankind

On a piece of red-brown sand, an unmanned small electric car with six pairs of wheels is driving.

The background is a dark starry sky, the brightest in the starry sky is a red and yellow fireball.

It is small and powered by solar panels.

Although it can't hold people, it contains another key accessory, a special electromagnetic furnace.

This unmanned car shuttled on the sandy ground and dug up a handful of red sand from time to time and poured it into an electromagnetic furnace. Then the red sand was completely melted by the high temperature of 2000 degrees.

Then the car came to a construction site that seemed to be half-built, and walked along the slope to the wall, and neatly covered the melted sand.

The melted sand quickly merged with the wall, and it was clear that the entire construction site was a masterpiece of this car.

But it is far from finished yet, and the trolley still needs to go back and forth and finally complete a sealed building.

Although it is only less than half completed, it can be seen that the final shape of this building is similar to the semicircular igloo of the Eskimos. Only this design can ensure that the car can be in the unfinished process at any time during the whole process. Come and go freely on the walls.

At present, all of this is completed under the control of the program that comes with the car. Judging from the amount of work that has been completed, the entire process has been in progress for at least several months.

But suddenly the car was trapped there after passing through a certain complex terrain in the process of digging sand, and became at a loss.

Then in the starry sky background of this reddish-brown land, a window was knocked out and a ladder descended.

Two staff members in space suits climbed down the ladder and went to the car to observe the situation.

This is not Mars, but a test base built somewhere on the earth imitating the environment and topography of Mars.

The entire base is completely sealed, and both the internal gas composition and the sand composition are similar to those of Mars, and from time to time, sandstorms are deliberately created.

The purpose is to simulate the status of the real Mars surface as much as possible, and to test various equipment here for a long time. Various facilities including this site belong to the space exploration technology company SpaceX. Their ultimate goal is to allow humans to migrate to Mars.

The current test content is the pioneer plan before manned landing on Mars.

SpaceX has various detailed plans and plans for landing on Mars. Mars is very far away from the earth, much longer than the distance between the earth and the moon.

Not only that, Mars is not always possible to go. The distance between the Earth and Mars will "meet" once every two years. In this state, the distance is a little bit closer, and then the distance will continue to increase. Long-term real-time communication cannot be done.

In other words, landing on Mars is different from landing on the moon, and you cannot return home immediately after landing.

Once aboard a rocket to Mars, it will be at least two years from now when we return to Earth.

People who go to Mars during this period must live there for a full two years, and the materials and oxygen that need to be consumed during these two years are huge.

In short, landing on Mars cannot be done in one go. Before people come to the surface of Mars, various supplies and houses for long-term survival must be built there in advance.

For this reason, there is a pioneer plan.

The content of the pioneer plan is to transport a batch of small robots, or small cars, to Mars. These robots have a wide range of types. They do not need to be controlled by humans. They are completely determined by internal AI based on the actual situation and use solar energy.

Different robots have different tasks. Some of them are responsible for collecting materials on the spot, using their own induction cooker to melt the sand and soil that can be found on Mars, and finally pile it up into a house.

The purpose of these houses is not only for people, but more importantly, the atmosphere on Mars is mainly carbon dioxide, which cannot be used for breathing.

Although plants will eventually convert carbon dioxide into oxygen, where there is almost no oxygen, agricultural cultivation is not possible. Plants consume oxygen to sustain life just like animals during germination and at night.

So these sealed houses have another important purpose, to prevent oxygen leakage and to grow plants.

The oxygen in the first house needs to rely on compressed oxygen transported from the earth, and then the first room can be used as an oxygen production base to gradually deliver oxygen to other houses.

But in short, agricultural planting on Mars must rely on closed rooms, and in order to supply the first immigrants, countless such rooms are needed to produce food and produce oxygen.

So these robots used to build houses have a heavy workload, and their reliability requirements are also high.

The first step of the pioneer plan is to send the construction robot to Mars first, and then nothing is left. After that, all that is needed is to wait slowly. I don’t know how many two years have passed. There will be one day on Mars. A certain area is full of houses piled up by construction robots.

At that time, the second batch of robots used to automatically grow crops will be transported to Mars, and finally, when all the resources for survival are available, will they consider sending people to Mars.

Although the final amount of engineering is huge, the calculation cost from Earth to Mars is not cheap, and it is impossible to send robots endlessly. In that case, the life and reliability of the robots sent in the past are very important.

Therefore, SpaceX, a space exploration technology company, has spared no expense in establishing a fully enclosed simulation base on the earth.

Their current progress is fairly smooth, but they have encountered a small problem. The construction robot has withstood the harsh conditions of the simulated Mars, whether it is the internal wiring or the various parts, especially the electromagnetic furnace. After repeated use, the performance Still stable.

The hardware has withstood long-term tests, but the company's most proud artificial intelligence software has faced challenges in this task.

Among the two staff members in fully enclosed uniforms, the one with the higher status is the engineer, and the other is his assistant

"Damn it, how come you stopped at this place, there shouldn't be any difficulty in crossing that small slope." After a period of observation, the engineer was the first to express his opinion, "Get the data first, and then manually control it. It seems that there is nothing difficult, but there is a little problem with the software. This is the fifth time this month.

After all, artificial intelligence cannot completely replace humans."

Then the assistant echoed: "Doesn't this algorithm in the company perform well on the highway?"

The engineer went on to explain: "Although in our eyes, driving a sports car on the road and driving a minecart for mining in a complex environment, these two seem to be similarly difficult tasks.

But it's different for AI, the latter is much more difficult than the former."

Then the two reported the current situation to their superiors. In a dark and secret meeting room, a man received a call, learned about the current situation, and reported to the people around him: "Judging from the current progress, the recovery of the remains The work may slow down, and the other bad news is that we also have a potential competitor."
