Chapter Eighty-Three: Success Around the Moon
The matter of the Shenlong has attracted so much attention all over the world, and it is naturally impossible to ignore it in China. Besides, with the development of online information nowadays, it is impossible to hide it even if you want to. What's more, although the current situation has not yet reached a foregone conclusion, risking their lives to save their comrades-in-arms, and still using manned aerospace aircraft, which has not been disclosed at all, represents the country's latest high-tech level of science and technology.
It's just that when they consider the cost of rescuing the seven people in heaven, some officials of the Ministry of Finance feel pain. A little fire on the rocket, it is hundreds of millions of yuan burned out, and the Shenlong, which is much more expensive than the rocket, cannot be brought back, so it can only be allowed to run in lunar orbit.
But these things can only be thought about. The No. 1 leader has already spoken after learning the specific situation, and he must save the heroes. With this sentence, let alone three or four hundred million, even if it is three or four billion, these officials under his command do not dare to show a trace of affection.
If you want to save it, you have to save China's speed. As the only satellite launch center for launching manned spacecraft, Dongfeng Space City, that is, Jiuquan Satellite Launch Center, began to prepare for rocket launch day and night at the fastest speed. Although it is not known whether Shenlong will finally be able to enter the lunar orbit to wait for rescue, but the preparation for the launch of at least two rockets at the same time has become a foregone conclusion, China has never allowed itself to be forced to the point of exhaustion, no matter when it keeps one hand or even several hands, this is already the most basic governing policy of the top leaders.
The ground was busy trying to save people, but a few people on Tiangong No. 1 and Shenlong were idle, especially the four people on Tiangong No. 1.
After the Shenlong carried out an emergency disengagement, Tiangong-1 immediately carried out an orbital change and moved again, allowing itself to return to the 470-kilometer low-earth orbit to operate steadily, and then inspected and repaired various parts to ensure that there would be no further problems. After these tasks were done, it only took four people 31 working hours, and the rest of the time was just monitoring the operation of the space station as usual, and the rest of the time, they were more concerned about the situation of the Shenlong.
As for the Shenlong, it has now flown a distance of 270,000 kilometers from the earth, because the Shenlong was injured, Xia Yu and the three of them did not dare to be too careless. In the process of inertial flight, in addition to leaving Wang Pengyu to monitor the flight number, Xia Yu and Wu Degao tried their best to conduct a relatively thorough inspection of the Shenlong. The final inspection results are quite gratifying, the rear cabin that has been unable to enter was spent nearly ten hours by the two people to break the partition, successfully entered the rear cabin to overhaul the fault situation, no major problems were found, as for the rocket engine, there is no fuel anyway, as long as it is OK to make sure that no leakage is found.
Others such as gas thrusters, avionics equipment, life-sustaining equipment, etc., after the final inspection did not find any problems, Xia Yu and Wu Degao were relieved, at least the Shenlong itself would not have any unexpected situations to cause headaches.
After 61 hours of Earth-Moon flight, Shenlong finally got extremely close to the Moon. This natural satellite of the Earth is a quarter of the diameter of the Earth, and due to the influence of the Earth's tides, it becomes synchronized with its rotation and revolution, so it always faces the Earth on one side, which we call frontal. The Moon's gravity is only one-sixth that of the Earth, there is no air on it, or only a layer of atmosphere so thin that it is close to a vacuum, and its magnetic field strength is less than one percent of that of the Earth. But those are all things in the future, for the current Shenlong, because preparations for orbit are about to be carried out, so Xia Yu and the three of them sat in the cockpit and began to operate as planned.
"Prepare for the third slowdown." Wang Pengyu said: "The ten-second countdown begins, 10,9 ......"
This is the last moment to test everyone, and the three of Xia Yu dare not be careless at all, because if the speed is too fast, the gravitational pull of the moon is very likely to be unable to pull the Shenlong, so that the Shenlong will be thrown out of the universe again after making an arc around the moon. However, if the deceleration is too much, without the rocket boost, it is very likely that because the orbit is too low and too close to the moon, it will fall directly to the surface of the moon after a few turns.
Either way, it would be catastrophic for Shenlong, even if the gravity of the moon was only one-sixth of that of the earth, once it fell headlong, there was no need to think about it except for the destruction of the plane and the death of people.
But the spaceship controlled by Xia Yu himself, as long as there is no problem with the spaceship itself, Xia Yu has enough ability to grasp even the slightest opportunity.
"In the process of deceleration, it is entering an orbit 270 kilometers from the surface of the moon, and the attitude is being corrected." Wang Pengyu nervously reported the number of the current flight on the side, Wu Degao also felt that his heart was pounding all the time, and now the fate of the three of them was all tied to Xia Yu's hands, once Xia Yu's control was wrong, the three of them had to finish playing, and they couldn't be nervous.
Entering orbit is not a one-time entry. During the several laps of the flight around the moon, the orbit must be constantly adjusted, so that the spacecraft can operate in the orbit at the same altitude as much as possible, which can be regarded as truly entering the lunar orbit.
Xia Yu's control was calm and steady, just as planned, in Wang Pengyu's surprise to read, Shenlong completed the entry into the lunar orbit and successfully operated in an orbit 220 kilometers away from the moon.
Looking at the gray planet that was under them at the moment, Xia Yu and the three couldn't suppress their ecstasy, they could finally stop worrying about any problems and wait for rescue with peace of mind. At the same time, 370,000 kilometers away on Earth, the flight control center in the Beijing Aerospace City also received the news of the successful entry of Shenlong into lunar orbit almost at the same time.
Suddenly cheering, all the people in the flight control hall cheered, shouted, and hugged each other happily, Yuan Limin cried with joy, only he knew how much pressure this happened to him, and even he felt that the plan he proposed was even more ridiculous. If it was before this matter, if someone mentioned that the Shenlong would fly to the moon, Yuan Limin felt that he would definitely not hesitate to cut him. What kind of international joke to let the space plane go to the moon? Why don't you fly over by yourself?!
But now, Yuan Limin feels that he is so lucky to be able to think of the method of letting the moon's gravity tie up the Shenlong. If it was a little later, or if he didn't think of this way, then the fate of the Shenlong, Xia Yu and the three of them would almost be doomed.
"Lao Yuan, I've worked hard for you." Cao Yanhua also had tears in the corners of his eyes, but patted Yuan Limin's shoulder with a smile and said: "They finally didn't miss the last chance, now it's up to us to rescue them successfully." ”
"yes." Yuan Limin nodded and said: "Now I can finally breathe a sigh of relief, and I have the face to explain the situation to the families of the four of them for the time being, otherwise I really don't know how to face their families." ”
