In the laboratory, Professor Shen Wei clearly heard Xu Jiawei's words between them, and he recognized Xu Jiawei's performance and praised Su Xiaojia's ability. He said to Chen Jie, who was sitting on the side: "You are also quite accomplished in the study of cosmic gravity, if it was you who was talking to Xu Jiawei just now instead of Su Xiaojia, what would you do?"

Chen Jie said: "I will be the same as Su Xiaojia, but I think it's a little early to do it now." ”

"Hmph, the current speed has reached 170, not far from the gravitational range of Proxima Centauri, I estimate that the moment when the velocity is about 200 is the edge of Proxima Centauri's gravitational range, it is not too early to start calculating. If the current course remains the same, it will undoubtedly crash into Proxima Centauri. Of course, this is not terrible, Zhou Wenbo will adjust the course in time. I think Xu Jiawei also knows this, what he means must be to let Su Xiaojia get it out and hand it over to Zhou Wenbo as soon as possible, and when the time comes, it will be seamless, this is the best way. ”

"Yes, Professor, you're right. ”

"Do you think the gravitational pull of Proxima Centauri will cause a reaction force?"

"Look, professor, which velocity do you want to refer to? If you refer to the speed of 100 light years, then you don't need to calculate, it must have a big effect, under the gravitational pull of the Proxima Centauri star cluster, it will definitely exceed 100, if you refer to the velocity of 200 places at the moment when you reach the gravitational range of Proxima Centauri, it is difficult to say, I have calculated its gravitational force, and the gravitational force of Proxima Centauri alone may have a reaction force, and the speed will decrease. But it's a star cluster, and the gravitational pull will be a little bigger, but because the interaction cancels out some of them, I judge that as long as the gravitational path is well maintained, it should be fine to keep it at 200. Of course, this is just a theoretical calculation, Su Xiaojia is on the spot, and the calculation will be more accurate. ”

"We'll see. The professor said, "How many days have they been out?"

"It's been 8 days. ”

"Oh, I think Xu Jiawei will act within an hour. You keep an eye on me, I'll go to the office and look at a file. ”

"Okay. Professor, the water in your teacup is gone, I'll give you some more. ”

"Oh, both of us are so focused. ”

"Actually, Xu Jiawei will handle it in the front, and we don't have to worry too much about it in the rear. Chen Jie refilled the professor's water, and the professor went out.

On the side of the spaceship, Lin Shanshan returned to the information desk, Su Xiaojia also calculated, and Xu Jiawei asked Su Xiaojia to input the data into Zhou Wenbo's workbench.

"Zhou Wenbo, the gravitational path has been entered, please adjust the course in time. Xu Jiawei gave instructions to Zhou Wenbo.

"Understood. Zhou Wenbo replied.

Su Xiaojia said: "Now the speed is 190, and after a while, it is expected that the speed will enter the gravitational range when it reaches 200, if you ignore the action of the No. 2 star, after the entire centaur flight, I calculate that the speed will be maintained between 250 and 280, here the stars are not big enough, and they are too close to each other, and the movement between each other will consume a little, so the gravitational force is very average." ”

"200 up. Xu Jiawei said.

"Look, Zhou Wenbo has begun to adjust his course, indicating that he has entered the gravitational range. ”

"And what about the time we get to Planet 2?" Lin Shanshan asked.

"It's coming soon. Xu Jiawei said, "Now that we have entered the gravitational range, it is estimated that it will take a day at most." ”

"The professor is here, and he looks like he's going to talk to you. Lin Shanshan said.

Lin Shanshan saw Professor Shen Wei coming over, and said to Xu Jiawei: "You see the professor's excited appearance, I must congratulate you, or you should report to the professor first." ”

"Good. Xu Jiawei reported to Professor Shen Wei, "Professor, we have now reached the gravitational range of Proxima Centauri, please instruct us on the next step." ”

"Arrived 5 days earlier than we expected, congratulations. The next step is to go to Planet 2 according to the original plan, calculate the orbit, and reduce the speed in time. ”

"Yes. ”

A day later, the spacecraft landed on Planet 2 at the scheduled time, which was the measurement point of the last Tianhua-1.

Professor Shen Wei said: "Xu Jiawei, don't rush out, the spacecraft will stop in place for an hour to observe, carefully observe all the situations in front and back, and wait for my instructions." However, if you confirm that there is an unfavorable emergency, you can take off and leave without my command. ”

"Yes, Professor!" Xu Jiawei reported, "Ma Biao and I have already put on our spacesuits and are ready to go down together." ”

"Agreed. Professor Shen Wei said.

Xu Jiawei paid great attention to the little bit of blue last time during the descent of the spacecraft - the place where there was suspected to be water, but this time there was no trace at all. He, Lin Shanshan, and Ma Biao are all observing and comparing very carefully, except for the stones that may change due to the effect of the wind.

An hour later, Xu Jiawei reported to Professor Shen Wei: "The ground temperature is 30 degrees, the sky is clear, the sun is abundant, the wind force is level 5, the gravitational force and magnetic field are similar to the earth, and nothing abnormal has been found." Ask to go down. ”

Professor Shen Wei once again reviewed the main data sent by the spacecraft just now, pondered for a moment, and issued an order: "Agreed." But you can't go beyond a radius of one kilometer, and you can't get out of the planetary car without instructions. ”

"Yes. ”

"Colleagues, Ma Biao and I are going down to the planet, this is the first time that human beings have gone to the planet of outer space, although we have made a deep observation of the situation outside, but after all, it is outer space, there is still a risk, in case of alien life, in trouble, we will rush back in time, if you lose contact, you will leave in time, don't wait for us, otherwise it will bring greater risk to the whole team, of course, if you leave and receive our distress signal can come back to rescue, haha. Xu Jiawei said to Yang Qi again: "After we leave, this place will be handed over to you." ”

"We're here to help. ”

Xu Jiawei and Ma Biao walked into the planetary car, Zhou Wenbo opened the door of the spacecraft, and the planetary car slowly drove out of the spacecraft.

In the laboratory, Professor Shen Wei stared at the planetary rover and saw Xu Jiawei drive about 500 meters and then turn around in place. He said, "Gawei, what's going on?"

"It's nothing, I just want to see what's going on around me. Xu Jiawei reported. With that, he drove on.

Seeing the planetary car drive into the middle of a large open space, Xu Jiawei reported that he was ready to go down. Professor Shen Wei looked at the video, the terrain was open, the wind was beautiful, and he couldn't see any movement, so he agreed to Xu Jiawei's request.

Xu Jiawei and Ma Biao walked out of the planetary car, which was the first footprint of mankind in outer space. It's a flat place, and there's nothing on the ground except stones. Xu Jiawei squatted down and picked up a small pebble on the ground, which was also the same color as the surface, rusty red. They walked forward for a short time, and Xu Jiawei made an astonishing discovery, and immediately reported to the professor: "I found a suspected plant, red, the same color as the surface, you can't see it if you don't look closely." As he spoke, he focused the camera on the plants on the ground, "It's similar to moss on the earth, and if you look closely, there's a lot of it, one by one, and I'm going to test it with a tool." ”

Professor Shen Wei was also very excited and approved Xu Jiawei's request.

Xu Jiawei scratched the red moss with a pebble and said, "Professor, that's right, it's a plant, we have found an alien plant, do you want to bring some back for research." ”

"No, if it is not handled well, it will have a catastrophic impact on the spaceship's biosphere, and as for bringing it back to Earth, I will leave this matter to Tianhua Xiaozhi. ”

"Okay, in order to avoid the creatures in the spaceship being affected, then I will ask Ma Biao to return to the spaceship and let Yang Qi analyze the structure of the plants in situ. ”

"Agreed. ”

Xu Jiawei asked Ma Biao to return to the spaceship and pick up Yang Qi. At the same time, he contacted Yang Qi and asked him to immediately change into a spacesuit and prepare for the mission. Yang Qi had also seen this plant in the spaceship, and he was going to ask to come down and study it.

Xu Jiawei continued to look around to see if there were any other plants. He found a square hole in a pile of red moss, he pointed the camera at the hole, and reported to the professor: "Professor, I see that this hole is very smooth, are there animals in and out?"

Shen Wei had never seen such a hole, so he asked Xu Jiawei to continue his investigation. Xu Jiawei walked further and saw more and more red moss, and there were more and more holes in this kind of square, which were of different sizes and were very smooth. He continued to report to the professor, saying, "Professor, I conclude that there are animals here, and that this animal is quadrilateral. Ah, miracles, professor, I found miracles. ”

Professor Shen Wei was very excited and said, "Jia Wei, don't get excited, say, what a miracle." ”

On the spaceship, Lin Shanshan also asked excitedly: "Jia Wei, tell me about a miracle." ”

Xu Jiawei said: "The red moss in front of it obviously feels a little wet, which means that there is water here, there is water, haha." ”

Xu Jiawei ran over excitedly and fell unexpectedly.

"What's the situation?" said the professor and Lin Shanshan to Xu Jiawei at the same time.

"Bonus, Professor, I slipped, and the ground slipped, because I was wet. I saw a lot of quadrangular animals crawling out of the ground, red ones. Xu Jiawei focused the camera on these small animals. Hehe, it seems that it is not enough for a biologist to come down, and life scientists must also be called. ”

Luo Dongfang's excited voice came from the spaceship, saying, "Okay, I'll act immediately, the planetary car is back, I'll put on my spacesuit and get down." ”

"Yes, you can prepare first, but you have to wait for the commander-in-chief's instructions. ”

Xu Jiawei stood up and looked intently into the distance, when suddenly a red fog floated over, and the speed was very fast, and said: "Professor, it's not good, just now I just looked at the front of me, I didn't notice in the distance, I saw a red fog floating over quickly, and the wind was blowing, the planetary car returned to the spaceship, and I had to evacuate on foot." ”

"Evacuate quickly and stay safe. ”

In the spaceship, Lin Shanshan shouted anxiously: "Captain, it's windy, the red fog is coming, come back quickly." ”

"Well, I'm back, don't be nervous, it's just a few hundred meters away, I'll walk in a while, Ma Biao and Yang Qi don't come down. The red mist came quickly with the wind, and as soon as Xu Jiawei's voice fell, the red mist filled the entire sky, only to hear Xu Jiawei say: "It's not good, I can't see it." ”
