The Qinglong-class space battleship that flew to Mars reached a speed of 200 kilometers per second after an acceleration that lasted 20 hours.

At this time, it is 160 million kilometers from Mars.

At a speed of 200 kilometers per second, it only takes 222 hours to travel to Mars.

Of course, taking into account the deceleration acceleration time, it is estimated that it will be 237 hours before reaching Mars.

In less than 10 days, you can fly from Earth to Mars, which is already very fast.

Captain Yin Siyong and several pilots were staring at the star monitoring system in the cockpit.

The speed of the battleship is extremely fast, but the risk also increases.

At the speed of the Qinglong class at this time, once it hits an asteroid, the consequence is that the ship is destroyed and people die, although Yin Siyong and others are in service through synchronous robots, but the cost of a Qinglong-class is quite a lot.

Therefore, they must keep an eye on the monitoring data of the star region, but all asteroids with a diameter of more than 1 centimeter must be monitored.

"It was reported that an asteroid with a diameter of 3.4 meters was detected at 14,783 kilometers ahead."

Report ......

Yin Siyong looked at the dense asteroids on the star map of the monitoring holographic projection, and his face was very cautious.

Although there are few large asteroids, there are not a few asteroids that are a few centimeters to a few meters between the orbits of the Earth and Mars.

And these asteroids are a deadly threat to high-speed spacecraft.

Sailing is too fast and a nuisance.

First mate Michelle thought for a while, then turned his head and proposed: "Captain, if a new power system is equipped on a large scale in the future, the speed of the spacecraft will be very fast, and the asteroids on the route must find a way to clean up." ”

"Well, I'll propose it to headquarters." Of course, Yin Siyong knows that the asteroids on the route are an issue that must be taken seriously.

If you don't pay attention to it now, there will be more and more spaceships of the company in the future, which is a huge hidden danger.

During the flight, the battleship constantly adjusted its flight direction.

Fortunately, the battleship has entered the inertial flight state at this time, and does not need additional power to continue accelerating, and the auxiliary thrusters that change the direction of navigation, and the internal power system of the battleship, do not use nuclear fusion to generate electricity, but use nuclear fission reactors.

The reason why nuclear fission reactors are used is that good steel is used on the cutting edge for the sake of cost-effectiveness.

The fusion power system is mainly used for the main thruster and the energy supply of weapons and equipment, while the electrical energy of the nuclear fission reactor is used for the auxiliary thruster and internal electricity.

And so it goes.

This voyage is 20 hours of acceleration and 20 hours of deceleration before the fusion power system will be activated.

It was only powered on for 40 hours, and only two of the Levi's rings were activated, which greatly increased the service time of the lithium-carbon nanolayer of the fusion power system.

In this way, the Qinglong-class nuclear fusion power system can fly back and forth from Earth to Mars 150~180 times before the lithium-carbon nanolayer of the nuclear fusion power system needs to be replaced.

After 210 hours.

At this point, the battleship was very close to Mars.

Yin Siyong immediately ordered: "Start slowing down!" ”

Next to the main thrusters at the back of the battleship, there are also six secondary thrusters, and the vents of these secondary thrusters are all diagonally forward and outward, just in the opposite direction to the main thrusters.

The function of these six secondary thrusters is to decelerate.

As the two Levi's rings of the fusion power system were activated again, six secondary thrusters began to eject dense high-velocity plasma.

The speed of the battleship decreased.

It is expected that after 20 hours, the speed of the battleship will drop to about 6 kilometers per second, and then the battleship will be captured by the gravitational pull of Mars, thus becoming a "satellite" of Mars.

And Mars is in orbit of rotation.

Phobos and Deimos have completely changed into the shape of Homo sapiens, and the surface of the star is densely covered with various man-made facilities.

Among them, Phobos is the location of the first shipyard on Mars, and it is also the spaceport where the Qinglong-class warships are intended to dock.

20 hours later.

The Qinglong-class space battleship slowly docked not far from Phobos, and the distance between the two sides was less than 150 kilometers.

After about half an hour, a maintenance ship came to the side of the Qinglong class.

A large number of maintenance personnel boarded the Qinglong class and began a comprehensive overhaul of the warship, especially the nuclear fusion power system that was put on board for the first time, which was the focus of the overhaul.

In addition, the maintenance of the spacecraft also brings a large amount of water, which is the nuclear fuel of the fusion power system, and the water is ionized, in which hydrogen is used as the fuel for nuclear fusion and oxygen is used as the working fluid of the plasma thruster.

Water is the best fuel for spacecraft to sail inside the solar system, after all, pure hydrogen, storage is very troublesome, using water just kills two birds with one stone, hydrogen as nuclear fuel, oxygen as the working fluid of plasma thrusters, and the storage of water is very simple.

Yin Siyong and others saw that it would take about 50 hours to overhaul, so they took the synchronization robot of the battleship offline, and then temporarily launched the synchronization robot of Zhurong City on Mars, and came here to take a tour.

Mars Zhurong City.

Not on Mars, but in the synchronous orbit of Mars.

To build a giant spiral arm city with a 15-kilometer spiral arm, Homo sapiens hollowed out more than a dozen iron-nickel asteroids in the asteroid belt.

At the end of the giant spiral arm is the standard gravity living area.

Eight spiral arms are attached to each ring chamber.

Yin Siyong came to the standard gravity zone through the synchronous robot, where the quasi-gravity is similar to the earth's gravity.

The ring chamber is also very large, reaching a diameter of 300 meters.

There are 2,793 new humans resident here.

Standing on the ground of the ring-shaped cabin, it is like being on the surface of the earth, with specially made villas on the ground, as well as a large number of flowers and trees.

Yin Siyong even saw some dragonflies and bees.

"It seems that this quasi-gravity can replace the earth's gravity."

"Probably not yet!" First mate Michelle crouched next to a tulip, and he smelled the strong scent of tulips.

That's right, the new generation of synchronous robots can smell the smell and feed back to the body exactly the same taste feeling.

Yin Siyong shook his head: "Actually, there is a way for Mars to become Earth. ”

"Do you mean to say additive program? The project was too risky for headquarters to agree to. Michelle, who stood up, looked surprised.

The so-called additive program is one of the backup plans for Homo sapiens to transform Mars.

The core principle is to carry asteroids from the asteroid belt and mine a portion of Jupiter's moon minerals to fill Mars.

As long as Mars has the same mass as Earth, then Mars' gravity is the same as Earth's.

This solution could solve the gravity problem of Mars once and for all, but the risk of doing so is so high that the project has been shelved for now.
