Half-immortal civilization

"Check the location of the crash, see where the nearest satellite is, and turn the camera!" Liu Haibo remained calm, or it wasn't dangerous at all.It can only be said that this is a small accident in space exploration.In exploring unknown areas, detector damage and even personal casualties are inevitable.

Just like when humans are exploring the ocean, there are fewer damaged equipment and dead scientists!Just don't report it.Sometimes, in order to explore the seas surrounding their own country, the country will order the use of troops to explore, thus causing more casualties.

"The nearest satellite is the No. [-] satellite, which mainly detects X-rays. Nano-satellites are known for their single and powerful functions, so they don't carry cameras." Lin Yun felt helpless.

Liu Haibo casually said: "Then scan the X-ray fluctuations here. I don't believe there will be no traces left! We have planned a human expedition this time, and have a plan to land on Ceres! Therefore, for everyone's safety, any problems cannot be Relax."

"Yes!"

The team leader has said this, so Lin Yun has no right to refuse; what's more, doing so is for his own consideration.

However, at this time, a few minutes have passed, and in this rapid space, it has lost its due value.It can only be detected that the original satellite still has wreckage.Based on the x-ray scan, it's more like a breakdown.

"It may be that asteroid debris has been encountered, and there are no problems with other satellites for the time being. We are preparing to release the same type of nano-satellite to make up for the detection of the No. [-] nano-satellite." Lin Yun checked and checked for a long time, and guessed.

"Okay. Continue to monitor." Liu Haibo was not surprised by such a result, but he was still a little cautious because he couldn't see the real reason with his own eyes.This is the sky after all.

However, it is not incomprehensible. The initial velocity of the spacecraft carrying the nanosatellite, plus the ejection velocity, is basically at a velocity of thousands of kilometers per second. Relatively speaking, the asteroids and various interstellar debris here are very fast. There are thirty to forty kilometers, and the slow ones are only a few kilometers per second.Maybe this is already fast on the ground, but in space, it can only be regarded as slow.Not to mention, the asteroid belt will often play a game of collisions, where large and small debris fly randomly, many of which are not regular at all.Therefore, it is entirely possible that nanosatellites collide with undetected debris.

In the asteroid belt, it can only be said that it is relatively empty, and it is safe in some cases; but it is not always safe.In fact, any cosmic environment cannot be said to be absolutely safe.

The nano-satellites are constantly sending back the detected data, and in the spaceship, various computers are running crazily.Astronomical data requires a lot of calculations. In many cases, in order to obtain accurate results, it can be accurate to dozens of decimal places.And some data itself is very huge.Such as the speed of light, the mass of the sun, etc.

"Didi...discovered Ceres! Didi...discovered Ceres!"

The dull spaceship was detonated by this news.

Ceres is one of the main targets of this exploration. As the largest asteroid that has been discovered in the asteroid belt, it can even be classified as a dwarf planet. Stable orbit around the sun; Ceres is very representative, and is the only dwarf planet in the asteroid belt that has been discovered.

Of course, this is not the point. The point is that Ceres is not only the largest star in the asteroid belt, but more importantly, it is said that there is a lot of water and solid water on it; some detectors even found that Ceres has jets of water vapor on the surface, Some are sublimated jets like comets.

For Liu Haibo, who understands Zhang Jingyuan's crazy ideas, having water is the most important thing.In fact, the most important thing to detect Ceres this time is to detect how much water and whether there is liquid water on Ceres.In addition, of course, there is still a question in the scientific community: whether there are other life forms in liquid water, even primitive single-cell life, or even simple life that does not have a cellular structure—such as viruses; of course, some people say that viruses cannot It counts as life.

But in space exploration, the discovery of life beyond the earth, even viruses, has extraordinary significance: it means that life should be everywhere in the universe!
Faced with this exciting news, Liu Haibo immediately ordered: "Start to slow down, release the probe, and prepare to explore Ceres. In addition, the space shuttle is ready to land on Ceres."

The location of Ceres was discovered by an accident of [-] million kilometers. Ceres is so big and it is the focus of exploration, so it was discovered early.

"Received. Ceres is now at a speed of 16 kilometers per second, and its orbital radius is 4.12 million kilometers. It is falling back, and its speed is increasing slightly. It is 1.03 million kilometers away from us."

Liu Haibo: "Keep moving forward and start slowing down at 700 million kilometers from Ceres!"

"Received. Please get ready. The spaceship will start to slow down in 28 hours. Please adjust your schedule and organize your rooms.

At that time, the spacecraft will flip over and accelerate in the opposite direction, and the acceleration will still be 8 meters per second.The spacecraft will enter the countdown in the last hour. "

At the same time, the spacecraft also sent the news of the upcoming landing on Ceres to the ground.But now the spacecraft and the earth are just separated by a sun, and the distance between them reaches about 5 million kilometers. It takes 7 hours for the signal to be transmitted back to the ground.

But now the spacecraft has 28 hours of stable flight time, and there is still plenty of time to receive signals from the ground, including commands.

No. 15 hours after the signal was sent, Liu Haibo did receive the communication from the ground, but it was not a small compressed package.After decompression, it turned out to be a series of pictures, which were the blessings of their family on the ground.At the end, there is only one sentence: I wish you all the best, and put life first in all tasks.

"Let's take a look." Liu Haibo quietly sent the picture to the host.

In this icy space, the greetings and care from the ground are so precious, but limited by the current communication technology and other reasons, there are not many exchanges between everyone and the ground.Although the superstring communication device can get in touch with the ground almost at any time, the cost is too high - several million power per hour, which is an act of death in space.Maybe in the end it is the loss of these millions of kilowatt-hours of electricity and the death of space!
With the care on the ground, the pilots are even more motivated...

27 hours...

"The spaceship is about to slow down, everyone please get ready. The countdown starts now: 59 minutes and 55 seconds..."

In space, the spacecraft is still moving rapidly, but now, using the thrust from the side, it starts to turn over slowly in space.This is just turning over, not changing the direction of flight, so it is relatively easy.It's just that such a turning around took a full 3 minutes.
