Rumble! A massive spacecraft spews thrust reverser engines and slowly lands over the Utopia Plains of the Northern Hemisphere of Mars.

The spaceship is a Tinder-class spacecraft that weighs 6,000 tons.

It didn't come to Mars alone, but was combined with four other Tinder spacecraft, with a huge radiation shield installed behind it, and then used the nuclear explosion of a miniature hydrogen bomb to quickly advance to the Martian side.

At present, through the nuclear explosion propulsion method, the unmanned spacecraft of Homo sapiens company only needs 45~127 Earth days to go to Mars.

Five Tinder ships are bundled together, one of which is a nuclear bomb depot and thruster core, and the remaining four Tinder ships are all coming to carry out missions.

Two of them will land in the Utopia Plains region of the northern hemisphere of Mars, where the first Martian surface research station - Utopia Station will be set up.

The other two Tinder spacecraft will stay in a sun-synchronous orbit on Mars as a Martian space station.

At this time, in the cockpit of the Tinder spacecraft that landed on Mars, three robots were controlling the spacecraft.

"Captain, everything is normal, you can land." The talking robot has a nameplate on its chest that reads: HX-0075.

"Permission to land." The other robot commanded directly.

"Roger, start landing."

The thrust reverser engine nozzle of the Tinder spacecraft kept adjusting, and the blue flames that spewed out also weakened little by little, until the bottom of the ship was less than 5 meters above the ground.

"Unfold the buffer rack."

12 mechanical legs pop out at the bottom of the spaceship, directly inserted into the loose sand on the surface, the hydraulic pump and shock absorbers of the mechanical legs, and the automatic balance and stabilization system of the spacecraft itself, keep the spacecraft firmly parked on the sand.

The blue flame from the engine vent was extinguished.

"The landing was successful." Robot 0075 makes a slightly joyful sound.

Robot 0074 looked at the instrument panel and immediately ordered, "Wang, check the various systems." ”

Robot 0076 immediately replied, "Roger." ”

As the captain of the robot 0074, he immediately contacted the captain of another spaceship, and the two sides communicated for a few minutes, and after confirming that there was no problem with each other, he wrote a report and replied to the Earth headquarters.

These robots are not artificial intelligence, but real "people".

To be precise, it's the people who control the robots, not the supercomputers and intelligent programs.

Intelligent programs supported by huge computing power, although they can simulate humans, and can also perform some relatively rigid tasks according to the set programs, they are not as flexible as humans after all.

Especially in the process of extraterrestrial exploration, aliens are often very far away from the earth, and the artificial intelligence of the spacecraft alone is not enough to cover everything.

After research, the Space Division decided to use the previously developed 16-ploid magnetic monopole crystal as a communication device.

In an ultra-low temperature environment, the 16-ploidy magnetic monopole crystal has a limiting service life of 2739 earth days, and a service life of more than seven years, which is obviously ready for practical application.

This improved version of the magnetic monopole crystal, as the core of the communication system, can communicate without delay.

At least for now, there is no significant delay between the Mars landing spacecraft and the Earth headquarters.

This is also the reason why these robots can be controlled by humans, in the communication module of the robot, there is a magnetic monopole crystal communicator, which corresponds to an exclusive control cabin of the earth headquarters.

In this way, the staff of the Space Division can directly control the robot and carry out tasks on Mars.

Although this new type of magnetic unipolar crystal has a service life of just over seven years, its non-delay communication effect is really fragrant in the eyes of the Space Division.

……

The controller of robot 0074 is called Dimahi, one of the two captains of the Mars landing spacecraft.

He had just reported the landing mission to Earth HQ when another robot, Jean 0076, reported to him about the ship's various systems:

"Captain, the ship's systems are in good order, and there's still a 62% balance of chemical fuel."

"Well, you and Wang get ready, and we'll start expanding the base later."

"Yes."

The Tinder spacecraft weighed 6,000 tons and carried a total of 2,760 tons of goods except for some fuel and ship structure.

】

These include two nuclear tanks for cobalt rods, seven experimental cabins, four tool cabins, and four replenishment cabins.

These cabins are not assembled, but need to be installed and commissioned in place.

When Dimahi stepped out of the cockpit, the sky was gray and hazy, which happened to be the season of frequent sandstorms in the northern hemisphere of Mars.

Because it is through the sensors of the robot, it can feel all kinds of movements, even if the biosensor technology of Homo sapiens is very advanced, Di Mahi can still feel a trace of unreality.

When the robot stepped on the sand, there was always a sense of incongruity, and Di Mahi was also very helpless about it, and the reason was clear to him.

Because the robot is on Mars at this time, and his body is on Earth, the different gravity coefficients and air densities of the two will make the robot operator feel uncoordinated, which is a very normal situation and an unavoidable situation.

Unless Dimahi comes to Mars, this sense of incongruity cannot be eliminated.

Under the influence of sandstorms.

Di Mahi only saw a hazy silhouette more than a hundred meters away, it was another landing spacecraft.

He looked up at the sky, a blue sphere, looming in the dust cloud.

That's the sun.

The sun seen on Mars is blue.

This is because the Martian atmosphere is dominated by carbon dioxide, so the sun is blue after being filtered by carbon dioxide.

He used the built-in assistance system, as well as the spacecraft's own magnetic field detector, to check the surrounding terrain.

Although the Utopia Plain is very flat, it is also relatively flat, and some undulating terrain of tens of meters is actually the norm.

Walking on the surface of Mars is like stepping on a marshmallow, not only the body is light and fluttering, but even the sand is easy to leave footprints.

This is caused by the relatively low gravity of Mars, and the frequent dust storms, combined with low gravity, cause the sand layer to accumulate on the surface very soft.

Through careful scanning by the magnetic field detector, he quickly identified a lowland 330 meters to the west, where a stable bedrock layer existed about 50 meters underground.

Although the various cabins do not have high requirements for the terrain, and there are no frequent major earthquakes on Mars, there is no need to worry too much about the terrain.

However, Dimahi chose an area that is more low-lying and has hard bedrock.

Although Mars does not have strong geological activity, it does not mean that you can rest easy.

On the contrary, Mars is more dangerous than Earth.

The reason is that Mars itself has a thin atmosphere and is close to the asteroid belt and Jupiter, and those asteroids that are thrown out by Jupiter's gravity can easily get close to the orbit of Mars.

Therefore, Mars is easily attacked by asteroids, and there is no dense atmosphere to wear away, and asteroids are very destructive to the planet's surface.

This is also the time to establish a surface base on Mars, and there is a problem that must be taken into account.

Di Mahi and Chen Baojun, the captain of a landing spacecraft, determined the specific location of the base layout together, and then the two began to start the base construction work with their respective team members.

However, considering safety, the bases of the two teams are not together, but about 200 meters apart.

This is just in case, to prevent the base facilities from being clustered together and being wiped out by asteroids.
