The three largest asteroids in the > asteroid belt are Homo sapiens, Marriage and Vesta, all with an average diameter of more than 400 kilometers.

There is only one dwarf planet in the main belt, Ceres, with a diameter of about 950 km; The rest of the asteroids are smaller, some even the size of dust.

Asteroids in the main belt are divided into three groups according to their spectrum and main form: carbonaceous, silicate and metallic.

In addition, collisions between asteroids may form groups of asteroids with similar orbital characteristics and color, and these collisions are also a major source of dust that produces zodiacal light.

After analyzing the relevant data of the asteroid belt, Yan Chengjian's tone became resolute:

"Crossing the asteroid belt is imperative, our Great Western Country can no longer withstand the attack of aliens, we must ensure the safety of our living space, we must garrison Europa."

The atmosphere in the room was suddenly solemn, and the confidence of all the generals was immediately firm.

Yan Chengjian pulled out a saber from his waist, which was a gift from Zhang Binhui.

"General Zhang will give us full support, and the Ziwei Military Academy will provide a thousand pieces of air film protection to help our fleet pass through the asteroid belt.

All the generals listened to the order, the vanguard fleet will be selected to set off, our Great Western Kingdom will end its secluded life from now on, and the fate of the Martians will be in our own hands. ”

……

On December 24, 2003, 120 space warships were quietly erected in a radius of 300 square kilometers at the Royal Cosmodrome.

With the order of the Emperor of the Great Western Kingdom, three hundred and sixty ion beams were sprayed out, and the entire land suddenly roared, and the rolling dust swept away along the plain, and all the warships took off into the air, leaving behind more than a hundred white tail flames that connected to the sky and the ground.

In the cockpit, Ma Tianyuan felt the sharp increase in weight, and looking at the distant Martian land on the screen, his mood was very calm.

The assignment was requested and approved in advance by the country.

In order to participate in the first cruise of the solar system in human history and show the surging strength of our Chinese sons and daughters, the military ordered the mechanic team led by Ma Tianyuan and He Qiliao to participate in this space journey, and they will witness a new history.

Dozens of seconds after liftoff, the two felt a sharp loosening of their bodies, and the starry sky was already outside the porthole, and the battleship group was already out of the atmosphere of Mars.

Not far away, ten huge motherships are quietly hovering in space, which is the interstellar cruise carrier established by the Martians in space, because the size is too huge, their design, construction, and assembly are completed in space on the far side of Mars.

The sidewalls of the mothership have all been opened, revealing the honeycomb-like battleship compartments in which all the space battleships will be moored and transported to the orbit of Jupiter.

The gravity system in the battleship had been activated, and when it flew to a distance of a hundred kilometers from the mothership, the battleship began automatic guidance, and one hundred and twenty ships silently flew towards their respective cabins.

When the spacecraft is secured by an airlock and slides into orbit into the mothership, all the hatches are closed, and the spaceship begins to warm up.

In the cabin, Ma Tianyuan and He Qiliao stepped out of the spaceship and stepped on the metal ground.

Each cabin here is an independent workspace, and the mechanic team led by them will complete the front-line support work here in the future.

Touching the newly mastered tools and looking at the huge cabin like an auditorium, Ma Tianyuan and He Qi Liao Chang exhaled: Is this also called an aircraft carrier? It's an interstellar satellite! We're really in the world of science fiction.

This team of mechanics is all elite soldiers from China, and from the moment they flew into space, these two hundred people couldn't believe what they were seeing.

They received a different mission, saw a strange-looking spaceship, flew to unimaginable space, and then reached the surface of Mars.

These soldiers were surprised to find that there were people on Mars, and their technology was far more advanced than that of Earth, and we, China, would cooperate with them.

The soldiers are very hardworking, they know their mission, and they want to learn something completely different.

The progress was staggering, and after a hundred times more effort than ordinary people, they were finally able to barely complete the rudimentary maintenance tasks and were able to repair the ship with the assistance of intelligent robots.

Then, here they were, and they embarked on a journey that they will never forget.

After getting familiar with the new job, Ma Tianyuan and He Qiliao stepped into their own command room.

Here is a small command cabin, where the two will receive orders from the fleet command.

After completing the routine report, He Qiliao opened the gun hangar, which was the auxiliary mecha hangar of the command cabin, and in the mecha hangar, three exoskeleton mecha were quietly placed, which were the models that the two were familiar with, but their configurations were more advanced.

After stroking each mecha and forcibly holding back the impulsive **, He Qiliao and Ma Tianyuan retreated, they knew that if it wasn't for an emergency, they wouldn't use these mechas.

On the center console, Ma Tianyuan unexpectedly saw a golden box, on which left a few big characters in Chinese - a little heart of the brothers, wishing the two eldest brothers all peace.

A warm current surged into the hearts of the two, no need to guess, this was left by Zhang Binhui.

When I opened the box, there were two pendants, which were completely carved from jade, and the shape was beautiful and the whole body was extremely bright.

When the two people took out one by one, the automatic communication device in the center console turned on, and Zhang Binhui's holographic image appeared in front of them.

"Well, you're still here, but I really don't want to."

He Qi Liao laughed: "It's beautiful, you want to get rid of us, no way." In the deworming work of the solar system, when did your galaxy team miss the two of us?

Let me tell you, in this territory, the two of us are also members of the Galaxy team, and we must be brothers when we go into battle. ”

Ma Tianyuan smiled and helped on the side: "That's, such a wonderful life, how can you let us miss it?"

If Xiaoqing hadn't been pregnant, she would have to come with her this time. Brother, let's do it again. ”

Zhang Binhui laughed, raised his fist in the holographic image, and the three of them touched together.

Before ending the call, Zhang Binhui repeatedly warned: Ma Tianyuan and He Qiliao must wear the jade pendant closely.

"Let's put it this way, the preciousness of these two things, if you really want to measure it in money, Mr. Cap will definitely be willing to go bankrupt."

"Wow, what a baby!"

He Qiliao hurriedly put it on his neck, and his saliva flowed out.
