Of course, with the Dijiang spacecraft, all the investigation projects on Ceres have been completed one after another. Then they conducted in-depth investigations on other large asteroids in the asteroid belt, such as Vesta and Marriage. God star and so on.

However, the results of the investigation were very disappointing at the beginning. Although, among the two asteroids, the Dijiang spacecraft has successively discovered a large amount of resources, it has not found any substances that the earth does not have, let alone found The existence of liquid water, and no trace of life was found.

Because although these two asteroids also have the discovery of solid water, there is no liquid water, because the distance between the two asteroids and the sun is too far, and the main material that makes up the two asteroids is not the same as Ceres. It is the same, but it is made of ordinary stones, and the core is also composed of stones. Among these two asteroids, even if all the water resources are added up, the overall mass does not exceed these two asteroids. The overall mass One millionth of that, so the water resources on these two asteroids are very scarce, but fortunately, the water resources of these two small stars are basically on the surface of these two asteroids, not on the surface of these two asteroids. A small star deep in the ground.

Although the water resources on these two asteroids are very scarce compared to Ceres, Mars, and the moon, they are still enough for human civilization to use after establishing a base in the future.

Dijiang, a space science research ship, has also started the return journey after completing the exploration of Vesta and Juno. After all, the distance will leave the earth and go to Mars and the asteroid belt for investigation. For nearly a year, although it is said that they stayed on Mars and Ceres for a long time in the middle, and some supplies were also carried out during the period, however, compared with the huge Dijiang, the spaceship and the cost of exploring the universe All kinds of resources, these few supplies are just a drop in the bucket.

Not to mention other things, just after the departure of the Dijiang, the number of various satellites launched, including navigation satellites, positioning satellites and other types of satellites, has reached more than 100,000. Most of them are just small satellites, but there are also some particularly large terminal relay satellites.

You have to know that this is just a satellite. In addition, since it came out, the Dijiang spacecraft has also launched a large number of unmanned probes in all directions of the universe. It is roughly estimated that there are at least several thousand probes. It is not enough to transport things by aerospace planes, they all need to return to the earth for reinstallation and replenishment.

The most important thing is that, in fact, the Dijiang spacecraft's deep space exploration activities this time are only the first trial voyage of the Jindijiang spacecraft.

After nearly a year of flying, it was time to go back for a large-scale inspection and maintenance.

At the same time, it is necessary to conduct a comprehensive evaluation of the various equipment and facilities inside the Dijiang spacecraft to see if its performance will improve after one year of use.

how is the situation.

In fact, the Dijiang spacecraft has encountered many problems during its space voyage in the past year. After all, the Dijiang spacecraft is the first real spacecraft in human civilization. At that time, the entire human civilization did not have any similar products to learn from, and could only rely on its previous experience in manufacturing ships in the sea to manufacture this spaceship.

It is also because of this that it is very normal to have many defects in the manufacturing process, but fortunately, the Dijiang spacecraft did not have any fatal defects during its space voyage this year, and no fatal defects were found at the same time. The problem.

At the same time, during the voyage, they also experienced several major hardships. Among them, the most impressive thing for the crew was that when the Dijiang spacecraft completed the investigation of Ceres and was preparing to go to Vesta, the Dijiang spacecraft Collided with an asteroid with a diameter of more than 30 meters, and the speed difference between the two parties reached nearly 100 meters per second.

But even under such a violent impact, the Dijiang spacecraft has withstood the test and withstood the impact. Although the Lijiang spacecraft also suffered some damage during the impact, the spacecraft At the top of the middle and rear part, during the impact at that time, a deep pit with a diameter of 5 meters and a depth of two meters was directly knocked out, but the steel plate of the spaceship did not break, which also led to the impact of this time. The crew members of the spacecraft that hit the collision, although some people were injured, no one was seriously injured or sacrificed. This also makes all the crew members of the Dijiang spacecraft, the designers of this spacecraft, and this spacecraft The makers expressed their deepest gratitude, because it was their responsible attitude that allowed them to escape this catastrophe.

You must know that under such a fierce impact, if it is an ordinary space fighter or aerospace plane, even an aircraft carrier on the sea and sea on the earth, it will definitely be smashed to pieces, and there will be no life left.

After the captain of the Dijiang spacecraft, that is, Captain Qiu, completed the last detection project, that is, the detection of Juno, it was announced in the broadcast of the Dijiang spacecraft that this time When all the missions were successfully completed and returned.

All the people in the Dijiang spacecraft cheered at once, although when the Dijiang spacecraft just set off, all the people on the spacecraft, including the crew and scientific researchers, had already done their best work. They are ready to contribute to the advancement of human civilization into the universe, and at the same time, they have already thought of the difficulties they may face when conducting interstellar investigations.

But in fact, the difficulties and obstacles they encountered during this investigation were much more than they imagined, and the difficulties they encountered were far beyond their imagination.

Although everyone on board has been injected with gene enhancement medicine this time, and it is still the most advanced level 10 gene enhancement medicine, even if they stay in a weightless environment for a long time, it will not cause irreversible effects on the body. However, living in space for a long time will still have a great impact on the mental health of the crew.

This is especially true when the spacecraft flies out of the orbit of Mars and reaches the asteroid belt.

At the same time, the long-term space life also made the crew miss the earth very much. I miss my family. Now that this mission is finally completed, they can finally go home. Even if the distance is far away, even if the spacecraft returns at the highest speed now, it will take at least one or two months to arrive. The happy mood of the crew could not be lost.

Finally, after more than a month of voyage, the distance between the spacecraft and the Earth-Moon system is getting closer and closer, and the mood of the crew members is naturally getting more and more excited. After all, the distance between them and the Earth at this time It is already close at hand, and they will be able to go home and reunite with their families in a few days.
