The spacecraft took off from the ground, and under the dual effect of the rocket's huge acceleration and the earth's gravity, the crew of the Pioneer was restrained in their seats, and it was very difficult to lift their arms at this time. It was not until it flew out of the dense atmosphere, that is, when the first stage of the rocket separated, and the second node was fired, that this aggravating force that was tightly pressed on the chair gradually disappeared.

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

When the last rocket ignited and Pioneer was close to near-Earth space orbit, Su Li, the intelligent core of Vanguard, began to pre-start the controllable thermonuclear fusion engine according to the program, and soon came the message that the startup was normal.

When the third stage of the rocket is shut down and separated, the Long March 7A launch vehicle as an auxiliary power has completed its mission at this time, and the last parts are all separated from the huge Pioneer, and these separated parts will soon gradually decline under the action of the earth's gravity, and finally fall into the earth, and then burn under the friction of the atmosphere, becoming meteor-like debris and finally disappearing completely.

The auxiliary power propulsion of the Long March 7A launch vehicle has been completed, 1 second after the separation of the components, Su Li officially started the controllable thermonuclear fusion engine, 10 seconds later, the Pioneer rotation program that continued to fly to space began, and the intelligent system adjusted the artificial gravity generated inside the Pioneer at the same time.

"Report on each other's situation!" Su Yichen asked loudly, and soon a safe answer came from the left and right and the rear, and then Su Yichen loosened the harness and operated the control station to contact the ground base center, and after doing this, he ordered the astronauts to continue to keep in touch with the ground base center. The order to perform their duties immediately stood up from their seats.

"I'll take a look at the back." Su Yichen said to his assistant Lin Guodong, signaling for him to temporarily work for his captain, Lin Guodong nodded slightly to show that he understood, Su Yichen stood up and first slightly adapted to the feeling of artificial gravity. Although artificial gravity can simulate gravity on the ground, so that the people inside the spacecraft can move in the spacecraft as if they were on the ground, after all, artificial gravity is only formed by the rotation of the outer circle of the spacecraft.

This difference is like stepping on a thick carpet, and when you walk, your feet are a little soft. However, Su Yichen knows that as long as he gets used to it, he can get used to it soon after adapting, and from the perspective of walking and other movements, the feedback of artificial gravity to the human body is still very good.

The cockpit is above the nose of the Pioneer. To get to the back, you have to go down to the lower level and then go through the long hallway. Su Yichen walked down the gangway, first looked at the situation of the cabins under the cockpit, and then walked through the corridor and slowly walked towards the middle of the spaceship.

Coming to the middle of the spacecraft, which is the astronaut's living quarters and the location of the stored materials, open the hatch passage and go inside, the first room is Su Yichen's captain's bedroom. But he didn't stop here, he kept going. At the end, there was a closed hatch over there, and only Su Yichen had permission to enter this hatch.

"Open the door!" Standing at the door, Su Yichen said softly, the hatch opened silently, and 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, and in the middle of it is a fixed device, and this device is Luo Yan's hibernation equipment.

"How's it going?" Su Yichen walked to Luo Yan's hibernation box, carefully looked at the exterior for collisions or other traces, and asked at the same time.

"Mom is in a good situation. The take-off of the ship did not cause any impact on the hibernation equipment, don't worry, Dad, I have already done a holographic scan. Su Li replied cheerfully.

"Good boy, it's really hard for you." There was no problem with Luo Yan and the hibernation equipment, which made Su Yichen completely relieved. A smile appeared on his face, and Su Yichen gently stroked the body of the hibernation box: "Xiaoyan, we have already taken off along the line, if you wait patiently, it won't be long before we can be together again." ”

In the cabin, Su Yichen sat by the hibernation box and talked to Luo Yan for a while, until Su Li reminded Su Yichen that the Pioneer had flown past the second Lagrange point and began to adjust the course ahead, that Su Yichen returned his thoughts from Luo Yan to reality.

"Keep the acceleration steady, and pay special attention to avoid collisions with small objects on the route."

"Knowing Dad, Su Li will pay attention."

Leaving the cabin where the hibernation equipment was placed, Su Yichen continued to inspect the interior of the spaceship, and after half an hour, he returned to the bridge, when he entered the bridge along the gangway, except for Lin Guodong in the cockpit, he was still sitting in the same position to operate, and Gao Jian, Mo Liwen, and Gu Chen had already left their positions, and they were looking up at the holographic cosmic image on the front and were amazed.

At this moment, the Pioneer had already crossed the second lagar day point and flew along the preset course towards the depths of the universe. The Earth behind the spacecraft is still clearly visible, in the dark of space, its unique azure is so bright and dazzling, and on the side of the spacecraft, the moon that accompanies the Earth's satellite, is like the faithful companion of the Earth, guarding the home star of mankind since ancient times.

On the front, there are stars in the sky, and observing the universe in space gives people a completely different feeling on the ground, and the whole universe is like a sea of stars, which looks so gorgeous and colorful. The stars are so clear and dazzling that they seem to be within reach, and those stars that cannot be observed with the naked eye on Earth shine in the deep universe.

"It's so beautiful!"

Looking at this sea of stars, even Gao Jian couldn't help but sigh, such a beautiful scenery is simply indescribable, compared to the boundless universe, the earth that gave birth to human life is so small, and their Pioneer spacecraft is more like an insignificant speck of dust in space.

Now, the route of the Pioneer spacecraft has been adjusted, and their goal is the direction of Sagittarius, because Pluto's current orbit is in the direction of Sagittarius M25 at three o'clock, and Pluto's brightness is 14 magnitude, and observation on the ground can only rely on professional astronomical telescopes, but in this unobstructed space, it is easy to locate it.

Vanguard has reached an acceleration of 28 kilometers per second, which is faster than the third cosmic velocity. At this speed, it takes only 3.77 hours to fly from the Earth to the Moon, while the Pioneer is designed to reach a maximum speed of 160 kilometers per second, which is more than the fourth cosmic speed, and if it flies at the highest speed, it will only take 40 minutes to travel from the Earth to the Moon.

Of course, to reach maximum speed, Vanguard will carry out a long period of acceleration, in order to ensure the carrying capacity of the controllable thermonuclear fusion engine, this acceleration cannot last forever, it takes about 30 hours from the initial velocity to the final acceleration to complete, and by the time all the acceleration is completed, Pioneer has already flown beyond the lunar orbit into the depths of space.
