On the 'Qinglong' spacecraft, as soon as the spacecraft passed through the orbit of Mars, Wu Renjie gave the order to launch the satellite.
Following his instructions, several small hatches were opened on the huge spacecraft. The robotic arms carried the satellites out of the warehouse one by one. Then, after adjusting the angle and speed, the satellites were launched one by one.
This area is very empty, without anything detectable or valuable, of course only now.
All of these satellites are satellites used to detect Mars. If there is an opportunity to fly to the orbit of Mars, scientists from the Institute of Astronomy and Astronomy of the Galaxy Academy of Sciences will naturally not let go of this opportunity.
Although Mars is still on the other side of the sun, and the distance between them is countless billions of miles, these satellites launched have also been scientifically set.
The speed of these satellites is very slow, and their flight trajectories are also along the orbit of Mars. As long as you need to wait slowly, when Mars orbits around again, the auxiliary propulsion systems on these satellites will start to work, pushing the satellites to Mars.
Within the gravitational range of Mars, it becomes a satellite of Mars and can begin to continuously provide information about Mars to the earth.
Although with the development of the interstellar space age, countless satellites and detectors have been launched to various places in the solar system, it would be good to have more detection satellites. Anyway, these things are cheap now and can't be spent much.
After the launch of the satellite for detecting Mars was completed, the 'Qinglong' spacecraft quickly returned to calm, and the crew began to go about their business again.
Some people are playing virtual games, and with the existence of quantum communication technology, there is almost no difference between the virtual world and the earth. You can meet and play games just like you. This has become the main way for the crew on the spacecraft to spend their time.
.
Some people are sweating hard in the gym. Everyone knows clearly that after three long months in space, if you still want to have a healthy body after returning to the earth, you must persist in maintaining a few hours of exercise every day.
Hard training as a child.
The intensity and time of this fitness cannot be discounted in any way, because this is not for others, but for yourself. Once the calcium in the bones in the body is lost, the whole person will be useless when he returns to the earth.
The scenery outside the spaceship remains unchanged. In the dark starry sky, there are many stars. Occasionally, you will find it very beautiful when you look at it. However, after being in such an environment for a long time, the crew on the spacecraft have long been tired of seeing such scenery.
I also miss the scenery on the earth even more.
Although the speed of the spacecraft is maintained at a terrifying speed of 50 kilometers per second, the void is really vast and vast. It gives people the impression that the spacecraft seems to be stationary, staying in the void forever, without any trace.
change.
If it weren't for the various advanced detection instruments carried on the spacecraft, Long Zhankong and Huang Zhibin of the astronomy science team on the spacecraft would have to re-measure the spacecraft and update the data of the spacecraft every day, and everyone would clearly know that they are on the same point.
, flying towards the asteroid belt.
"Captain~ We have to start slowing down the spacecraft!"
After these days continued for a few more days, Long Zhankong and Huang Zhibin found Wu Renjie and made suggestions to him. At this time, he was already very close to the asteroid belt and would soon enter the asteroid belt.
"Is there any new order from the Earth Command Center?"
Wu Renjie nodded. According to the plan and itinerary, it was indeed almost time to slow down, but he still had to listen to the instructions from the Earth Command Center.
The spacecraft sailing in the vast void relies on the large number of scientists at the Earth Command Center to use supercomputers to conduct comprehensive calculations and analysis.
On the other hand, we cannot all rely on the Earth Command Center. The judgment of the scientists and engineers on the spacecraft is also very important, because only the people on the spacecraft can clearly know all the extraordinary situations at the first time and can make the most timely decisions.
reaction.
"The Earth side means the same thing, start slowing down~"
Spaceship deputy Liao Fanghong nodded and said.
"Start slowing down~"
Wu Renjie nodded and ordered.
The second-generation anti-gravity engine uses the huge gravitational force of the star, and the same is true for deceleration. There is no need to install a reverse propulsion system at all, and it relies on the anti-gravity engine to start slowly decelerating.
"Turn on x-ray detection, gamma-ray detection, beta-ray detection, infrared radiation detection, and magnetic field detection!"
"Turn on quantum matrix radar and produce 3D stereoscopic images!"
"Activate the weapon system and be ready at any time."
"Launching unmanned exploration satellites."
Orders were issued from Wu Renjie one by one. The asteroid belt that was about to arrive was not a warm and empty void. It was possible to be hit by an asteroid at any time, so the detection radar must be turned on.
In order to save energy, it is not turned on.
At the same time, the weapon system is also on standby at any time. When a spacecraft flies in the void of the universe, it usually flies in a straight line. If it has to change its flight trajectory to avoid the impact of meteorites and asteroids, the energy consumed will be astonishing, especially
The greater the mass of the spacecraft, the greater the energy consumed.
Therefore, under normal circumstances, we will use weapons to destroy meteorites and asteroids in front of us. The 'Qinglong' spacecraft also carries weapons such as rail guns developed by the Galaxy Science Research Institute, which can definitely deal with ordinary asteroids.
There is no problem.
The principle of the so-called rail running is actually very simple. It is to accelerate something like a hard tungsten rod to a certain extent to hit the target, thereby destroying the target.
Because the speed of the spacecraft itself is very fast, now it is tens of kilometers per second. Based on this speed, the launched rail will run at a speed that can be imagined. The faster the speed, the greater the energy it carries, which is enough to easily deal with it.
Ordinary asteroids.
As for the unmanned detection satellites released, they are to grasp the situation of a large area of void as much as possible. These detection satellites are very cheap, one-time products, and the quantity is relatively large. It is also the purpose of Galaxy Technology Group to grasp more situations of the solar system.
That's why some unmanned detection satellites are continuously released along the way.
The crew of the spacecraft also began to get busy, starting to repair the spacecraft and equipment, conducting emergency drills, etc. At the same time, they were also full of expectations for the asteroid belt that was about to arrive.
As the days passed, the speed of the spacecraft became slower and slower, and it got closer and closer to the asteroid belt.
"Is this the asteroid belt?"
"Why do I feel that there is no difference from before? It's just as empty and lonely, and there's no asteroid in sight."
Wu Renjie carefully looked at the picture displayed on the monitor and repeatedly confirmed that the Qinglong spacecraft had indeed entered the asteroid belt at this time.
But when he looked out into the dark void, there seemed to be no way out. He couldn't see scenes like those in science fiction movies. Countless large and small meteorites, asteroids, etc. were heading towards him.
"Haha, we have indeed entered the asteroid belt, but it is almost difficult to detect an asteroid with the naked eye, unless the asteroid is very close to us."
When Huang Zhibin heard this, he couldn't help laughing.
"Although there are countless asteroids in this asteroid belt, there are now more than 1 million known and numbered asteroids. All of these asteroids are very massive asteroids in the asteroid belt. For example, Ceres is in the asteroid belt.
The most massive asteroid among them is, of course, called a dwarf planet to be precise."
"In addition to these numbered millions of massive asteroids, there are countless asteroids of different masses in the entire asteroid belt, and the number is difficult to estimate."
"However, all these asteroids are distributed in the vast asteroid belt. The distance range of this asteroid belt is very wide. It is 2.17-3.62 astronomical units from the sun, which means that it is more than a month wide.
Astronomical unit."
"Not to mention its length, it is a circle around the entire solar system. A simple calculation shows how vast the asteroid belt is."
"In such a huge area, even though there are a lot of asteroids, the density is not as high as we imagined. You can only see asteroids with the naked eye unless they are very close."
"What we mainly rely on to detect asteroids is various detection instruments."
Long Zhankong also smiled and explained to everyone. When Wu Renjie, Liao Fanghong and others heard this, they all suddenly understood, even though everyone had gained a lot of knowledge in this regard.
But compared with professional astronomy scientists such as Long Zhankong and Huang Zhibin, the gap is immediately apparent.
"Didi~Didi~"
"Discover asteroid~"
Just as everyone was chatting, the alarm on the spacecraft sounded, and everyone immediately became energetic. They all quickly connected to the network on the spacecraft with the virtual watches they wore and started to get busy.
"This asteroid is 4,276 kilometers away from us. According to the analysis of spectral images transmitted by the detection satellite, it is mainly composed of 40% iron, 30% copper, and the rest is basically silicon."
"Its diameter exceeds 1,556 meters, its overall shape is irregular, and its mass exceeds 300 million tons. It is not our cup of tea."
In Wu Renjie's mind, the virtual machine directly transmitted relevant information to his brain. He used the computer to calculate and analyze the data, and quickly obtained the relevant information about the asteroid.
At the same time, this information was also announced to Wu Renjie, Liao Fanghong and other crew members.
