From University Lecturer to Chief Academician

The ocean is pitch black at night.

The sky and the sea have been connected by darkness, and the vast and dark distance seems to be a light that can swallow everything.

In the haze, the shimmering boat was bouncing along with the waves, and several figures on the boat were chatting in low voices, doubts and worries revealed in their words, "How come there are burnt fishes in the sea?"

"Only the broken part is cooked, and the head part of the fish is still raw..."

"How is it cooked? Is it a fish that fell from another boat?"

"It's impossible to grill such a big fish whole, right? The raw parts are still fresh, and the fish doesn't seem to have been processed."

"It shouldn't be man-made."

"Isn't it man-made? Is there a fire-breathing fish in the sea? Or was it hit by an engine or some other part of a ship?"

"This statement is quite reliable."

Some people couldn't help but look around, as if hoping to see other ships, but everywhere they looked was only darkness. Combined with the sound of waves lapping against each other, people couldn't help but feel a sense of fear in their hearts.

Several people gathered together and continued to talk in low voices. Some of the bolder ones continued to look towards the sea. Suddenly someone pointed at the sea and shouted, "Look! There are bubbles!"

Others immediately went over to see, "It seems there are bubbles!"

"Is there something big down there? Otherwise, why would there be bubbles..."

Zhang Yaokun reacted immediately and yelled, "What are you talking about! Don't remember the news? Forgot what we came here for!"

Others reacted immediately.

The news has reported before that there were a lot of bubbles rising from the sea where the cargo ship sank. Their job was to investigate this phenomenon and collect as much information as possible.

I thought I would get nothing, but I didn't expect to find bubbles on the sea surface.

Someone tried it with a long pole and picked up some bubbling seawater. After putting it in a bag, they found that the seawater was still cold. "It seems to be just bubbles, nothing changed."

"Maybe it contains some chemical components." Zhang Yaokun shook his head.

In fact, it's really just bubbles.

In the vast sea, no matter how high the temperature is or how strong the reaction is, heat will be lost quickly. The sea surface is not boiling, but the gas produced by the thermal reaction below floats out of the sea.

At this time, someone suddenly said, "Our ship... won't it break too?"

Zhang Yaokun shook his head, "Don't worry. We came here by boat. I saw the news last time. The bottom of the large cargo ship melted. Our ship didn't go deep into the water, so there shouldn't be any problems."

The others immediately breathed a sigh of relief.

Someone said in confusion, "Don't you find it strange? I have been investigating the sea surface for a while and this phenomenon did not appear, but it appeared as soon as we arrived?"

"What a coincidence!"

"It seems so..."

"Don't think too much, let's just carry out the mission." Zhang Yaokun quickly interrupted the others' discussion.

At this time, everyone was not afraid anymore.

If you suddenly encounter a similar phenomenon, you will definitely feel very scared. People are always afraid of the unknown.

However, by associating the execution of the task with the appearance of bubbles on the sea surface, they can easily analyze that the bubbles were artificially created. It is likely that the superiors received the news in advance, or that the superiors knew how it was created and then let them know. They come to collect information.

Regardless of the reason behind it, letting them collect information would definitely not lead to death.

Zhang Yaokun immediately commanded to start the task. Their main job was to put a long pole down, then drive the boat for a certain distance, and then fish it up after a period of time.

The long pole is specially made from many metal hollow tubes and can be lowered continuously to a depth of more than 100 meters.

During the process of lowering the long pole, Zhang Yaokun kept holding the fixture and pointed his flashlight at the sea surface, carefully staring at the downward pole. Suddenly his eyes froze, and he immediately rubbed his eyes with his hands and looked again.

A shout came from the side, "Look!"

"what is that!"

"The sea is lit up!"

The water below suddenly becomes brighter!

Everyone stopped what they were doing and stared blankly at the bottom of the sea.

The surroundings were completely dark, which also made the light in the sea appear brighter. The light in the sea seemed to be a light pillar, extending a certain distance from the sea, and then rushed out far away.

When the light beam burst out of the sea, it was already very weak, but it still formed a hazy light. Against the backdrop of darkness and sea water, it looked like a light door from a distance.

Zhang Yaokun couldn't help but open his mouth wide and exclaimed, "What is that?"

"I just said it felt like I was in hell. Isn't it really the gate of hell? The gate of hell that bursts out from the bottom of the sea?"

"This is no time for joking!"

Zhang Yaokun opened his mouth slightly, looked into the distance in shock, took a deep breath, calmed down and commanded, "Drive that way!"

"ah?"

"Really?"

"..."

Before the others could speak, they saw that the light door had disappeared, and there was no more light in the sea water. What they saw just now seemed to be just an illusion.

The surroundings became pitch black again.

After a long time, someone asked blankly, "Captain Zhang, are you still driving that way?"

Zhang Yaokun swallowed his saliva and said firmly, "Put down all the poles first, and then drive in that direction!"

At this time, even he was a little scared.

In the pitch-black environment, a bright light suddenly burst out of the sea water, and a gate of light was vaguely formed. It existed and disappeared in just a few seconds. It was very scary to think about it.

Science seems unable to explain it!

After a while, everyone calmed down and began to analyze various possibilities, "It can't be a warship, right?"

"submarine?"

"If it's a submarine, it's possible. Maybe it's just the light emitted by the submarine, but the submarine...must know about us, right?"

"Maybe just thinking of us as a passing boat?"

"Or is it a submarine on a mission? But what do we do? Why does it feel like we are involved in some kind of big incident? Why are we asked to investigate?"

"Is there a possibility that, for example, some country's military has come into contact with aliens, and then our superiors know about it and ask us to collect intelligence?"

"this……"

"You have a great imagination!"

"If it's true, don't get caught. Maybe aliens are more interested in human bodies... I don't know what aliens look like. Would they be beautiful?"

"What a mess, you are crazy about women!"

Someone's joking remarks made the atmosphere much better, and a few people continued to perform the task.

Zhang Yaokun urged the work, "Hurry up and finish it. Go back quickly. If you want to discuss it, we can discuss it after we get back."

"Captain Zhang is right."

"I don't want to stay in this damn place for a second!"

"Let's go quickly!"

…

Strong S-wave experimental base.

After the high-energy laser irradiated the black ball, the researchers recorded the duration of the black ball, and then allowed the equipment to continue running for ten minutes. After confirming that nothing was found, the equipment was turned off.

The experiment ends here.

Wang Qiang, Zhou Jun and others all felt a little regretful, because no new discoveries were made during the experiment, and high-energy laser irradiation seemed to be no different from ordinary laser irradiation.

As for the location of a strong S wave in the Mediterranean, we can only wait for the news to come back.

After the experiment was over, Wang Hao also talked with Wang Qiang and found that Wang Qiang seemed a little disappointed, and encouraged him not to be discouraged, "Research is like this, it is difficult to make discoveries."

"Your experimental idea is already very good. Maybe there will be discoveries on the other side."

"When there is news, you must tell me as soon as possible."

Wang Hao was also curious about what Zhang Yaokun's team would discover, but he didn't expect any big discoveries. After all, strong S waves are created in seawater. Even if there are some new phenomena, conventionally speaking, there are endless Sea water can also provide some cover.

He continued to pay attention to the movements of the spacecraft.

The spacecraft completed the release of the probe as planned, and has been captured by Jupiter's gravity and controlled to orbit Jupiter.

The task of releasing detectors is very large, because there are more than fifty detectors, of which more than thirty are owned by spacecraft companies. Most of the detectors will be used to detect the asteroid belt.

After that, it takes a long time to approach and orbit Jupiter. From approaching Jupiter to the satellite orbiting Jupiter, it takes at least more than three days. Jupiter's gravity is very strong, and there are many uncertainties in the environment near Jupiter. The spacecraft must To approach slowly, the orbit around Jupiter will also slowly shrink until the orbital altitude is close to Europa.

During this process, the main nozzle of the spacecraft is facing the direction of Jupiter to ensure the stability of the spacecraft.

After the orbit approaches Europa, the spacecraft will conduct detection work on both sides of Europa. Once it launches an ordinary detector, the detector will fly around Europa and send back a lot of data.

The purpose of the first detection is to confirm that the surface of Europa is landable, and then the second detection will be carried out.

What was launched this time was a small spacecraft, the "Bird" unmanned spacecraft ordered from the space agency. "Bird" did not use lateral anti-gravity technology. The hull was only composed of superconducting batteries and Hall thrusters. It was equipped with some high-end detection equipment.

The 'Bird' unmanned spacecraft does not have an anti-gravity function and is used for planet landing detection and is a one-time use.

Compared with ordinary detectors, the 'Bird' unmanned spacecraft has a much higher carrying capacity and can be installed with a lot of precision detection equipment and even a remotely controlled landing vehicle. The landing vehicle will then send back temperature and air density. , wind force, ground hardness and many other data.

The main mission of the 'Bird' unmanned spacecraft is to find a suitable landing site for the manned Thousand Falcon spacecraft.

Europa is different from the moon in that not all of its surface is hard. In other words, not every location can be landed.

In addition, there are many "underwater" vents on the surface of Europa, which are similar in shape to volcanoes on the earth. The water ejected from the underground is very large, and it will also form water or ice on the surface in a short time. A similar environment is not suitable for the landed Thousand Falcon. It is fatal to the spacecraft.

Spacecraft control center.

Wang Hao and Zhu Qiqiang sat together, constantly checking the messages sent by the spacecraft——

"The orbit of the spacecraft is close to Europa, and the data sent back by the detector shows that Europa can land..."

"The orbit of the spacecraft is stable, release the Bird-07 detection spacecraft..."

"Qinniao-07 has found a suitable landing site, has released the landing vehicle, and is under control..."

"Everything is normal. Do you want to land the Thousand Falcon spacecraft and wait for instructions..."

Looking at the messages sent one by one, Wang Hao asked Zhu Qiqiang, "When did you receive the last message?"

Zhu Qiqiang said, "Half an hour ago, the spacecraft was still circling Jupiter normally, and now it is continuing to collect information about Europa."

Wang Haodao said, "Just let them decide. If everything is normal, just log in as planned. Tell them that they must not take risks. Safety is the most important thing."

Zhu Qiqiang nodded and shouted into the microphone, "Send a message and say that the command center agrees and let them make their own judgment."

…

Spaceship.

The control cabin has been waiting for news from the ground command, and everyone is looking forward to receiving the "command center consent" message.

They also started working in an orderly manner immediately.

Some are responsible for preparing the Thousand Falcon spacecraft and landing personnel, others continue to process the information sent by the landing vehicle, and some are responsible for checking whether the shooting equipment is functioning normally.

During the landing on Europa, photography will be carried out throughout the process and the images will be sent back to the ground control center.

If everything goes well during the landing and the Thousand Falcon spacecraft successfully returns to the spacecraft, the ground control center will send part of the video footage to the TV station for 'live broadcast'.

It is said to be a live broadcast, but in fact it is just playing videos.

Of course, to a certain extent, it can actually be regarded as a live broadcast. After all, the delay is not too long. The delay in signal transmission speed from Jupiter to the Earth is too high, so a delay of several hours is 'understandable'.

The mission to land on Europa was Thousand Falcon-02. The pilot of Thousand Falcon-02 was Wang Hui, and the person who carried out the sampling mission was Du Junsheng. In other words, there were only two people on the team that landed on Europa.

The reason there are only two people is because the Thousand Falcon spacecraft has a limited number of people, and the limited space in the cockpit must carry more supplies for the operation of the life support system.

Even if a part of the space is reserved for carrying resources, the time the spacecraft can perform the landing mission will not exceed fourteen hours. What limits the operating time is not the electric energy, but the life support system.

The Thousand Falcon spacecraft cabin does not have a complete oxygen supply system. It uses high-pressure oxygen bottles, including the life support system in the spacesuit, which also uses high-pressure oxygen.

At the same time, the spacecraft cockpit also needs to continue to maintain stable pressure, temperature and air environment, which requires continuous consumption of resources.

This limits the time for manned landings.

14 hours is still quite tight in terms of time. It will take more than two hours for the Thousand Falcon spacecraft to break away from the spacecraft, fly close to Europa and stabilize and synchronously orbit Europa.

Because of the limited performance of the Hall thruster, it will take at least four hours for the spacecraft to take off from Europa and return to the spacecraft.

Then the time left for landing on Europa, collecting samples, and other work will not exceed seven hours at most.

Seven hours sounds like a long time, but after landing on Europa, the surrounding environment is not the peaceful environment of the Earth. It will take a long time just for the spacecraft to land stably.

Various subsequent tests are required before the astronauts can slowly step off the spacecraft and then collect samples.

It takes a long time to transport some equipment from the spacecraft to normal operation.

Although the task ahead is difficult, everyone is still looking forward to the landing work, because they are about to realize the first human landing on a planet outside the Earth-Moon system.

This will definitely become a landmark event recorded in history!
