In the cockpit of the Shenlong, the three people who were originally a little lifeless were all refreshed after hearing Yuan Limin's words, Xia Yu hurriedly pressed the communication button and asked, "Command center, please speak, what can be done?" ”

"The flight number information is being uploaded, you can take a look." Yuan Limin grabbed the communicator and said with some excitement: "I don't know how high the success rate of this method is, but this is the only way I can think of." I'm really sorry for you for putting you in such danger......"

Listening to Yuan Limin's voice suddenly became a little stalky, Xia Yu suddenly felt very heartwarming, this old man also said that he was sentimental, obviously he was the most sentimental person. Pressing the communication button, Xia Yu opened his mouth and said, "Old man Yuan, you are just an ordinary person, so don't put anything on your shoulder." Regardless of the final outcome, I want you to know that at least I never blamed you for arranging me to carry out this task, and besides, it ended up like this, and it was the result of my own good advocacy, and it has nothing to do with you. ”

Wang Pengyu and Wu Degao on the side also adjusted their mentality at this time, and comforted Yuan Limin one after another, but Yuan Limin was moved to tears, and he couldn't cry for a while.

Soon, the flight plan uploaded from the command center had been successfully received, Xia Yu and the others hurriedly opened it, and the three of them were dumbfounded.

On the computer monitor, a picture of a running track is being displayed. The elliptical line centered on the earth in the graphic is the current orbit of the Shenlong, and at some points of the line, it is marked with very detailed operational information including flight speed, flight attitude, etc., and what really makes Xia Yu and the three of them dumbfounded is this line that represents the orbit, one of which is actually on the moon.

"What do you think?" Wang Pengyu asked.

"What else can I think, I can only do it." Wu Degao said: "It's better than not knowing where to go." ”

"yes, I thought so too." Xia Yu nodded in agreement, and then said: "Old Wu, let's make another calculation according to this plan, Peng Yu, you contact the command center and tell them, we have decided to act according to this plan." ”

After Xia Yu finished speaking, he immediately started to do calculations. In order to minimize the possibility of accidents, Xia Yu went directly into the consciousness space and began to calculate using the simulation performance of the starry sky.

At the same time, the information that the Shenlong Aerospace Plane was trying to save Tiangong-1 has also spread around the world.

The chain reaction caused by the impact of space debris has not only affected Tiangong-1, but many satellites, including the International Space Station, have been destroyed.

With the close attention of various ground observation stations around the world, Shenlong has been observed since its launch into low-earth orbit, and everything that has happened since then has not escaped the gaze of countless pairs of eyes far away on the earth's surface.

"Good afternoon, everyone. This is CBS, and now insert a newly received news that the Chinese aerospace aircraft Shenlong, which went to space to rescue the Tiangong-1 space station, has separated from Tiangong-1, but aerospace scientist Robertson said that the current speed of Shenlong is close to the third cosmic speed......"

According to official Chinese sources, there are currently only three pilots on board the Shenlong spacecraft...... BBC's Brian reports from Beijing. ”

"This is NHK Radio, and according to an official who did not want to be identified, the Shenlong that saved the Chinese space station was not a manned space plane, but was controlled by an on-board computer with a high degree of intelligence......"

The news media all over the world are lively, and this kind of important international event comparable to the Olympics makes the news people like sharks that smell fishy, frantically chasing any possible news, with the slightest movement, or even no movement, all kinds of reports will be spread all over the world.

No matter how noisy it was on the ground, in the cockpit of the Shenlong at this time, Xia Yu and the three of them were not so leisurely, they were closely observing the flight orbit position and specific flight number of the Shenlong.

"The rocket fuel is exhausted, the rocket engine stops working, and the current orbital speed of our position has reached 15.1 kilometers per second, which is the last half of a circle, and we can't go around the earth anymore."

"There are 7 minutes left to get to the departure point, prepare the gas thruster to change course, I hope there will be no more accidents this time, I have been scared enough today." Wu Degao laughed at himself.

Hearing Wu Degao's words, Xia Yu couldn't help but smile and said: "Aren't we all the same, but as long as there are no problems in this operation, we still have a good chance of success, and the time to persist for a month is just to change from the earth's orbit to the moon's orbit, and we are about to become China's first batch of people to fly around the moon. ”

The relaxed atmosphere deliberately created by Xia Yu played a role, and Wang Pengyu and Wu Degao's mentality also calmed down a little, and they were about to make a last fight for their survival.

"The one-minute countdown to the orbit change begins, 28, 27, 26...... 3, 2, 1, start. As Wang Pengyu's voice fell, controlling the only gas thruster that could still be used as power on the Shenlong, Xia Yu steadily controlled the output speed, and the Shenlong, which was constantly in condition during this flight, finally stopped making trouble, and obeyed Xia Yu's command very obediently, successfully changed the orbit, and entered the earth-moon flight.

In Beijing Aerospace City, in the flight control center, when Yuan Limin saw the successful orbit change of the Shenlong, he couldn't help but breathe a deep sigh of relief. This time, there were no problems, and the successful orbit change of Shenlong meant that it could breathe a sigh of relief for the time being in the 62 hours before reaching the lunar orbit. Although the Shenlong still needs to undergo three deceleration work on the way, it seems that the gas thrusters are in good working condition and there should be no more problems.

The average distance of the moon from the earth is 380,000 kilometers, but because the orbit of the moon around the earth is an elliptical orbit with a circumference of 28 days, the moon is only 350,000 kilometers away from the earth, when the moon is at perigee, the moon is about 14% larger than the moon when it is moving at apogee, and the brightness is increased by about 30%, and the moon can reach more than 400,000 kilometers when it is farthest from the earth. This also means that the time it takes for the spacecraft to reach the moon is not fixed, and depending on the flight plan, the time required varies even more.

For example, China's first lunar exploration satellite Chang'e-1 took 13 days from launch to lunar orbit, but as early as 1969, the manned spacecraft Apollo 11, which was used when mankind landed on the moon for the first time, only took 4 days from launch to landing on the moon.

Xia Yu and their flight plan to reach the moon and enter the orbit around the moon this time is only about 62 to 72 hours, which is not a long time, but the time required to launch the Shenzhou spacecraft to rescue them half a month later is longer than this, but fortunately, the food and water loaded on the Shenlong are sufficient, and the oxygen exchange equipment and backup power supply are also prepared, so although there are no solar panels that can be used to charge, it is more than enough to survive for a month.
