The spacecraft took off from the ground. Under the dual action of the huge acceleration of the rocket and the gravity of the earth, the internal crew of the Pioneer were struck in the seat. It was very difficult to lift the arm at this time.∈◆ Until the dense atmosphere, that is, the first section of the rocket separated and the second node was fired, the gravity tightly pressed on the seat gradually disappeared.

"The second section shutdown separation is completed, the second section shutdown separation is completed, the Pioneer engine is ready to start, and the Pioneer engine is ready to start..."

When the last section of the rocket was ignited and Pioneer was in close proximity to space orbit, the intelligent core of Pioneer Su Li began to pre-start the controllable thermonuclear fusion engine according to the program, and soon the normal startup information came.

When the third section of the rocket was shut down and separated, the Long March 7 A-type launch vehicle, as auxiliary power, had completed its mission at this time. All the final components were separated from the huge Pioneer. The separated parts would soon gradually decline under the action of the earth's gravity and eventually fall into the earth. Then, it burned under the friction of the atmosphere, becoming a meteor-like fragment and finally disappeared completely.

The auxiliary power propulsion of the Long March 7 A-type launch vehicle has been completed. One second after the components are separated, Su Li officially launched the controllable thermonuclear fusion engine. After 10 seconds, the Pioneer rotation program that continues to fly to space begins. The intelligent system also adjusts the artificial gravity generated inside the Pioneer. When the rotation operation is stable, Su Li finally issued a command that everything is normal and that the crew inside the spacecraft can start to move freely without their seats.

"Report their own situation!" Su Yichen asked loudly, and soon all safety answers came from left and right and behind. Then Su Yichen loosened his tied seat belt and operated the console to contact the ground base center. After doing this, he issued an order to continue to contact the ground base center to the astronauts. Each of them performed their duties, and then stood up from his seat.

"I'll go back and take a look." Su Yichen said to his assistant Lin Guodong, signaling him to work for his captain temporarily. Lin Guodong nodded slightly to show his understanding. Su Yichen stood up and adapted to the feeling of artificial gravity first. Although artificial gravity can simulate gravity on the ground, making the inside of the spacecraft move in the spacecraft like the ground, after all, artificial gravity is only formed by the rotation of the outer ring of the spacecraft. Although Su Li's fine control, it gives people a slightly different feeling.

This difference is like stepping on a thick carpet, and the foot feels a little weak when you walk. However, Su Yichen knew that as long as you adapt, you will get used to it quickly. Judging from the movement and other movements, the feedback from artificial gravity to the human body is still very good.

The cockpit is above the front end of the Pioneer. To go back, you must first go down to the lower level, and then pass through the long corridor. Su Yichen walked down the gangway, first checked the situation of the cabins under the cockpit, then walked through the corridor and slowly walked towards the middle of the spacecraft.

When he arrived at the middle of the spacecraft, this was the astronaut's living area and the location of storage materials. When he opened the cabin door passage and walked in, the first room was Su Yichen's captain's bedroom. However, he did not stop here, but continued to move forward. At the end, there was a closed cabin door there, which only Su Yichen had the right to enter.

"Open the door!" Su Yichen stood at the door and said softly, the cabin door opened silently. The moment Su Yichen stepped in, the soft light inside gradually lit up.

The interior space of this cabin is about 700 cubic meters. The plane area is about 120 square meters. In the middle is a fixed device, which is Luo Yan's hibernation equipment.

"How is the situation?" Su Yichen walked to Luo Yan's hibernation box, looked carefully at whether there were any collisions or other traces outside, and asked at the same time.

"Mom's situation is very good. The takeoff of the spacecraft has not had any impact on the hibernation equipment. Don't worry, Dad, I have already conducted a holographic scan." Su Li replied happily.

"Good boy, thank you so much for your hard work." Luo Yan and the hibernation equipment had no problem, which made Su Yichen completely relieved. A smile appeared on his face, and Su Yichen gently stroked the box of the hibernation box: "Xiaoyan, we have taken off smoothly. If you are patient, wait, we will be together again soon."

In the cabin, Su Yichen sat by the hibernation box and talked to Luo Yan for a while. It was not until Su Li reminded Su Yichen that the Pioneer had flew past the second Lagrangian point and began to adjust the direction ahead that Su Yichen returned to reality from Luo Yan.

"Keep the acceleration stable, and pay special attention to avoid collisions from a small celestial bodies on the route."

"I know Dad, Su Li will pay attention."

Leaving the cabin where the hibernation equipment was installed, Su Yichen continued to patrol the inside of the spacecraft. After half an hour, he turned around and returned to the bridge. When he walked along the gangway, Lin Guodong was still sitting in his original position in the cockpit. Gao Jian, Moliwen, Gu Chen and the other two had left their position, looking up at the front of the holographic universe image and were amazed.

At this moment, the Pioneer had already crossed the second Lag sun point and flew towards the depths of the universe along the preset route. The earth behind the spacecraft is still clearly visible. In the dark space, its unique blue color is so bright and dazzling. On one side of the spacecraft, the moon, which accompanied the earth, is like the faithful companion of the earth, and has always guarded the mother planet of mankind since ancient times.

On the front are stars in the sky. Observing the universe in space gives people the feeling that it is completely different on the ground. The entire universe is like a sea of ​​stars, looking so colorful. The stars are so clear and dazzling, as if they can reach out to touch. The stars that cannot be observed on the earth with the naked eye are shining in the deep universe.

“It’s so beautiful!”

Looking at this ocean of stars, even Gao Jian couldn't help but sigh that such a beautiful scenery is simply indescribable. Compared with the boundless universe, the earth where human life was born is so small, and their Pioneer spacecraft is more like a tiny piece of dust in space.

Now, the route of the Pioneer spacecraft has been adjusted. Their target is Sagittarius, because the current position of Pluto is at the direction of three o'clock in Sagittarius, and Pluto's brightness is 14. You can only rely on professional astronomical telescopes to observe on the ground, but it is easy to locate it in this unobstructed space.

The acceleration of the Pioneer has reached 28 kilometers per second, which has exceeded the third cosmic speed. At this speed, it only takes 3.77 hours to fly from the earth to the moon, while the Pioneer's design maximum speed will be as high as 160 kilometers per second, which has exceeded the fourth cosmic speed. If you fly at the highest speed, it will only take 40 minutes from the earth to the moon.

Of course, to achieve maximum speed, Pioneer will accelerate for a long time. In order to ensure the carrying capacity of the controllable thermonuclear fusion engine, this acceleration cannot continue. It takes about 30 hours from the initial speed to the final acceleration. When all accelerations are completed, Pioneer will fly over the moon orbit and enter the depth of space. (To be continued, please search for Piao Tianyi, the novel is better, updated and faster!
