"Starry sky, I can't see where it is." In the consciousness space, Xia Yu stared at the picture projected in, no matter how he looked at it, he didn't find any suspected products of technological civilization, let alone an interstellar spaceship.

"According to the positioning information I just received, the wreckage of the research spacecraft Ladidas is located here." In the picture, a dark area of the deep ravine on the surface of the moon is enclosed by a small red frame, and now the far side of the moon is obviously facing the sun, but it is still pitch black, not to mention the wreckage of the spacecraft, there is hardly even a trace of light, and it is impossible to observe the situation there with the naked eye alone.

However, if the location of the shipwreckage is determined, you can find a way to notify the country, after all, it is a scientific and technological civilization of the same type as the earth, if you have the information of the spaceship, even if it is just the wreckage, the country's scientific and technological level will probably be greatly improved. Xia Yu touched his chin, and his mind began to wander around what method to use to inform the country of his discovery.

"What are you doing?" Wang Pengyu looked curiously at the surface of the moon, but he didn't see anything except the messy craters.

"Oh, I think I saw something just now, so I wandered for a moment." Xia Yu turned his head and said while checking the flight number of the Shenlong: "There are still 5 minutes to be able to establish a connection with the ground again, according to the plan, the Shenzhou spacecraft should be in orbit on the earth now, I hope it will be smooth." ”

"Of course it will be smooth." Wang Pengyu said with a smile: "We should also be bitter." ”

"Hahaha, that's right." Xia Yu smiled: "But it's not easy to go to space again after going back this time." ”

"You still want to go to space?" Wang Pengyu pursed his lips and said: "The Shenlong can't return to Earth with us, so there is no plane to fly in a short time, but I think you are very likely to be transferred back to the test flight unit." Unlike me, I am not a member of the test flight unit now, and this time I have the experience of space flight, and it is no longer possible for the country to choose me for normal manned space operations, and my next lift-off flight will be seven or eight years later. ”

Xia Yu smiled when he heard this, and said, "As long as I can continue to fly the plane when I go back, I have no complaints." ”

"It's hard to say." Wang Pengyu smiled very proudly: "You are a hero now, driving the latest aerospace plane to save people in space, and returning to the ground with this experience, hehe, I'm afraid you will be pushed out of the top to be a benchmark, let alone fly a plane in the future, I'm afraid the plane won't let you touch it, and the country will directly raise you to old age." ”

Rolling his eyes, Xia Yu was noncommittal. No matter what kind of experience he brings back to Earth, he is still a member of the test pilot unit, and even if his superiors want to promote his officer, it is still within the military system. As long as he is still in the army, as long as he is still a flying officer, Xia Yu is not afraid of not having a fighter jet to let him fly.

Besides, unless the superior leader directly removes his military status, even if they have any requirements, they will still ask for their own opinions, for a flying officer like Xia Yu with a special experience, they can no longer face it with an ordinary attitude, especially after the No. 1 leader made it clear that after Xia Yu returned to Earth, he would have a meal with him.

"Shenlong, this is the command center, please answer when you receive it." In order to save power, now in addition to the basic life-sustaining equipment, other electrical equipment is directly turned off, after all, Shenlong does not have solar panels like Tiangong-1, in order to maintain a longer time, saving is necessary.

"The Shenlong has received it, please speak to the command center."

"The Shenzhou spacecraft has been successfully launched, and is currently flying in the Earth's orbit as scheduled, and will enter the lunar orbit in 227 hours and 18 minutes.

The notice from the command center made Xia Yu and Wang Pengyu both happy, and in less than ten days, they could start to return to Earth. It only takes more than 2.4 kilometers per second to get rid of the moon's gravity, which is not only a saving of most of the fuel compared to the second cosmic velocity needed to leave the earth, but also shortens the return time, and it will take up to fifteen days for their feet to step on the earth's ground again.

The jubilant Xia Yu and Wang Pengyu clapped each other's palms, and the time to return to Earth was just around the corner.

On the ground, after the Jiuquan Satellite Launch Center sent the Shenzhou spacecraft into space, it was about to prepare for the second launch mission, and there were still four people on Tiangong-1. But fortunately, the distance is much closer than that of the Shenlong, and without considering the loading of too much fuel, the return capsule that can carry five people can be directly sent up, and there is no longer a need for the third rocket launch mission.

Three days later, the Shenzhou spacecraft, which had lifted off again, completed its docking with Tiangong-1, and then returned to Earth safely in the eyes of the whole country, successfully saving the first batch of four people. Although it cannot be said that the whole world is celebrating in China, the staff in the relevant positions and the people who really care about the astronauts in the sky are really relieved, and the next thing to do is to welcome back the last three heroic astronauts once again safely, so that this drama ends perfectly.

A few days later, the Shenzhou spacecraft, which had flown thousands of miles to the moon's orbit, was now running synchronously with the Shenlong in the same orbit, and the distance between the two spacecraft was only a short distance of more than 30 meters. However, although the Shenzhou spacecraft was accurately controlled into orbit, it was only 100 meters away from the Shenlong and the speed was basically synchronized, but in order to get the Shenlong to get close to the Shenzhou spacecraft to a sufficient distance, Xia Yu and the three of them still spent more than 3 hours to control the entire distance, and the next thing they needed to do was to carry out a spacewalk, from the Shenlong to the Shenzhou spacecraft accurately, and it was Xia Yu who carried out the spacewalk with the safety rope.

The safety rope, also known as the umbilical cord, is the rope that ties the astronaut to the spacecraft when the astronaut is out of the cabin to work. It is called an umbilical rope because this special rope not only prevents astronauts from accidentally drifting away from the spacecraft during space operations, but also serves the function of supplying oxygen and communication to the spacesuit.

After confirming that the safety rope had been connected, Xia Yu stood at the door of the Shenlong, looking at the Shenzhou spacecraft that was running synchronously thirty meters away, ready to jump.

The appearance of the Shenzhou spacecraft is not like the Shenlong aerospace aircraft, which has an obvious spacecraft shape, and its appearance actually looks closer to a satellite. The entire Shenzhou spacecraft is composed of four parts: the orbital module, the return module, the propulsion module and the additional section, and in order to obtain power during orbital operation, solar panels are also installed on both sides of the orbital module, which is a thing that follows the kind of wings stretched out on the satellite.

"Are you ready?" Wu Degao and Wang Pengyu floated in the hatch, holding Xia Yu's safety rope with both hands, in addition to preventing things from being hung up during the movement, if Xia Yu jumped off, he had to rely on the two of them to pull it back.

"Well, I'm ready, I'm jumping." Xia Yu replied, then held the hatch of the Shenlong with both hands, bowed slightly, kicked his legs back, and immediately floated in the direction of the Shenzhou spacecraft.
