Annihilation of the solar system

The four new guests looked at this great creation of human civilization outside and were deeply shocked by its complex and sophisticated structure. Wei Xu looked at the mechanical arms in the dock, and the passage trestle was already so shocked that he could not close it.

Mouth:

"The dock, the name is apt, it really looks like a dock on the ground where ships are assembled."

Jing Yuhui smiled:

"Haha, you are very good at observing. The main purpose of building this space station is to assemble large-scale space defense platforms and spaceships in low-Earth orbit. Do you see that our space station now looks like an upside-down '凵'

Character?"

When Jing Yuhui said it, everyone found that it was true. And their current position was in the middle of the bottom horizontal line of "凵". Those vertical cabin sections separated by tens of meters were like the vertical sections on both sides of "凵".

And the main cabin section of one of the two poles they just passed was like the intersection of two vertical poles connected horizontally with the character "凵".

"This great project is so incredible. If I hadn't seen it with my own eyes, it would be hard for me to imagine that we have such a powerful space carrying capability," Xia Lan couldn't help but sigh.

A proud look appeared on Jing Yuhui's face:

"When the ground-level swinging project is put into use, the main cabin will be extended by more than 100 meters. And for those vertical cabin sections, in addition to the current downward ones, upward cabin sections will also be installed.

By then the configuration of the entire space station will look like an 'H' shape, and the weapon platforms and spacecraft required for our low-Earth orbit defense will be built simultaneously in the upper and lower space docking bays. A large starport-style space station like ours will have a total of

Will assemble and build 4."

Then Jing Yuhui pointed to their lower right side:

“Look, that’s your spaceship ‘Hongyan’.”

Everyone looked in the direction of Jing Yuhui's finger, and sure enough, at the far end below, they saw a spaceship fixed on two vertical sections by a trestle passage. Compared to the majestic starport, the spaceship looked very mini and cute.

.

She looks like a launch vehicle lying flat. What is different from launch vehicles on Earth is that there are portholes on her head and the front 1/3 of the hull, and there are x

Three rows of solar panels arranged in a shape.

In the second half of the spacecraft, four engines like rocket boosters are arranged in a "ten" shape, but they are not arranged close to the hull, but are connected to the ship through four structures similar to missile wings.

Body connected.

"Hongyan was launched into low-Earth orbit through a ground-based heavy-duty rocket and the Karman Project. The assembly and debugging of the spacecraft was completed two weeks ago. This is also the first spacecraft assembled by Tiangong-3.

We have repeatedly tested all systems and are now ready to set sail." Jing Yuhui said proudly as he looked at the spacecraft.

Lin Tianyu looked at the magnificent project in front of him and couldn't help but sigh:

"We calculate data, build models, make plans, and look at drawings all day long on the ground. Only when we come here and see it with our own eyes can we understand the true meaning of our existence. Are you right, Xia Lan?"

Xia Lan glanced at Lin Tianyu and said calmly:

"I am really lucky to be able to participate in this project, otherwise I would never have imagined the picture in front of me."

When Wei Xu saw the two of them, he felt that he had no food in his stomach, so he could only say angrily:

"Senior Brother Lin, that's not entirely true. Without the efforts of the Academy of Sciences, the Academy of Engineering, the Aerospace Center and the entire industrial system, we wouldn't be able to come here."

At this time, a middle-aged man of medium height came to the command cabin. After seeing Jing Yuhui, he adjusted his posture, straightened his body and said sonorously:

"Report to the stationmaster! The 'Hongyan' has completed the final inspection and all systems are working normally. All cargo materials have been loaded and can set sail at any time."

Jing Yuhui used an armrest above his head to gently move his body to the man:

"This is Hou Peng. He is a veteran astronaut with a record of staying on the space station for more than 2,000 hours. He is experienced and can fly various types of spacecraft. I believe he can help you complete your mission."

Lu Yuanzhou smiled and nodded at him:

"My name is Lu Yuanzhou, and I am the commander of this mission. These three beside me are our mission load scientists. I ask for your help in the next few months."

Hou Peng forced out a stiff smile politely:

"You're welcome, Commander. I will definitely cooperate with your work. I have just made a final inspection and the Hongyan is ready. We can set sail as planned at any time."

Lu Yuanzhou turned his head to look at Xia Lan, and the eyes of the three of them were filled with eagerness:

"Well, okay! Then let's go to the spacecraft and have a look."

Hou Peng turned around and floated to the front:

"Please come with me."

The four of them, Lu Yuanzhou, followed Hou Peng and Jing Yuhui as they walked through the space station and came to the interior of the Hongyan spacecraft through the docking port.

Although it is much narrower than the space station, it is also more spacious than a shuttle. At the head of the spacecraft is a cockpit with two seats, and several large monitors are installed around the portholes, which are displaying various instruments and data.

There are various switches and levers above the head of the seat and within reach of the hands. There are three bunk beds arranged on one side behind the cockpit. The beds are independent of each other like a capsule apartment, and other living areas are arranged on the other side.

facility.

Behind the compact living compartment and cockpit are the bulk cargo compartment, material compartment and service compartment that ensure the normal operation of the entire spacecraft. Hou Pengpiao went to the co-pilot's seat and sat down:

"This spacecraft was urgently modified for this mission. The main body is simply modified from the previous generation space station. Most of the space on the spacecraft is used to carry the life support materials we need for this voyage, so we

The living quarters are quite cramped, and you may have to try to overcome them after several months of space travel."

Wei Xu floated to the side of the row of beds and found a bunk with his name on an upper bunk.

He lay down on it with great interest and tried it out. It was about the same size as a bed in a college dormitory. The difference was that there was a set of flexible safety belts on the bed that could fix him to the bed to prevent him from drifting away when he fell asleep.

There is a small reading light above his head and a personal storage box. Unlike the storage boxes on Earth, this door opens downwards, and the personal belongings inside will not fall out directly after opening.

Come down, but float in the same place.

Wei Xu seemed to be very satisfied with the living conditions here. He floated out of his bunk:

"I think this environment is good! It's much better than the dormitory environment in college!"

Everyone laughed. Lu Yuanzhou also sat in the commander's driving position. These operating buttons, screens, and data were no stranger to him. The simulation training on the ground had made him very familiar with the operation of this spacecraft.

.

He operated on the touch screen, called up the star map and put it on the largest display:

"Now the Earth's orbit is approaching, and it will soon reach the closest point of Earth's orbit. We are already in the optimal transfer orbit window period."

Everyone came close to the cockpit and looked at the display screen. Jing Yuhui said:

"Yes, this period is the best window period. If we set sail now and use the Earth's gravity slingshot to accelerate, we can reach Venus in 65 days. If the mission is executed smoothly, the return time should not exceed three months."

For the three Ph.D.s in cosmology, they knew exactly what Jing Yuhui wanted to express.

Wei Xu looked solemn:

"If we set sail later, the return orbit will be longer, and the longer it will take us to return."

Xia Lan's eyes were firm:

"Yes, so we should set sail immediately."

Hou Peng looked at Jing Yuhui and then at Lu Yuanzhou:

"The spacecraft has been inspected many times and we can set sail at any time."

Lu Yuanzhou looked at his crew members. Their eyes were full of anticipation, excitement and determination. Then he looked at Jing Yuhui:

"Then let's set sail immediately!"

The attitude-adjusting engines scattered around the spacecraft emitted faint firelight, and the Hongyan spacecraft slowly separated from the connecting channel.

Lu Yuanzhou and Hou Peng sat in the cockpit and calmly drove the spacecraft. Xia Lan, Wei Xu and Lin Tianyu tied themselves to the folding seats on the spacecraft with seat belts. The "Hongyan" slowly left the star.

Hong Kong, when the distance was far enough, Lu Yuanzhou said to the space station via radio:

"Get ready to accelerate."

"Okay, good luck to you!"

Jing Yuhui replied.

At this time, Jing Yuhui, who was on the space station, saw only a small dot of the spacecraft left. The small dot suddenly flickered, just like a shaking mirror suddenly reflected a beam of light in his eyes, and it flashed by.

.When the light dissipated, the Hongyan was no longer visible.

Xia Lan felt her body shake slightly, a weak acceleration flashed by, and the spacecraft entered a high orbit.

Looking at the earth outside the porthole again, it is obvious that the spacecraft is already running on an elliptical orbit, because the earth outside the porthole can be seen with the naked eye as it gradually moves away from itself and then gradually approaches.

After several orbit changes, the eccentricity of their orbit around the earth has become very large. Hou Peng stared at a screen on the instrument panel that displayed an orbit simulation diagram:

"The orbit height and speed required by the gravity slingshot have been reached, and the acceleration command can be executed!"

Lu Yuanzhou pressed several buttons on the console, and a series of countdowns appeared on the display. Lu Yuanzhou issued instructions:

"Get ready to accelerate, everyone."

The four boosters at the tail of the spacecraft ejected four ferocious tongues of flame, and the spacecraft hummed and vibrated as it began to accelerate. Xia Lan and the others had experienced several overload tests of the Carmen Project, and they no longer had any nervousness about this level of overload.

There is no fear at all, but those buzzing vibration sounds make people feel uncomfortable.

A minute later, the spacecraft returned to its previous calm state, and Hou Peng confirmed the orbital position:

"We have entered the Earth-Venus transfer orbit with an orbital speed of 16.5 kilometers per second. We will arrive at Venus in 59 days."

Lu Yuanzhou breathed a sigh of relief, took off the seat belt that was tied to his body, and looked back at Xia Lan and the others who were also putting away the folding seats:

"Our journey has officially begun!"

Xia Lan floated to the porthole and looked at the earth that was gradually receding with a firm gaze:

"Wait until we bring back the chips for victory!"

At this time, the space station’s loudspeaker came from the space station’s Jing Yuhui’s voice:

"Hongyan, it has been confirmed by the ground and the space station. You have successfully entered the transfer orbit, and the orbit entry accuracy is very high. From now on until you reach the low-Earth orbit of Venus, we will confirm the status with you three times a day. I wish you all the best

!I am Tiangong No. 3."
