Great Country Academician

Chang Huaxiang was a little surprised when he heard that Xu Chuan was preparing to start manned missions.

"Isn't it a little too fast to start the manned landing mission after the New Year?"

Xu Chuan shook his head and said, "No, it's time."

After a pause, he handed over the document report he brought, and then said: "Manned landing on the moon is different from manned landing on the moon."

"Manned landing on the moon is now quite mature for us, and there is no window period."

"But landing on Mars is different. The distance between Mars and the Earth is not comparable to that of the earth and the moon. The average distance is more than 200 million kilometers. The most distant time can reach 400 million kilometers. The closest time is a full 55 million kilometers. "

"Even for us, there is a window period for landing on Mars. If we want to choose the most time-saving route, July to October every year is almost the most suitable time."

"So if we want to successfully launch the manned mission around July, we should start preparations almost now, including the navigation trajectory that needs to be planned and calculated, how much supplies, how to rescue in the event of an accident, etc."

Chang Huaxiang frowned slightly and said, "I know this. That's not what I mean, but whether it is a bit too fast to start manned missions this year."

"Unlike manned landing on the moon, we don't have any experience in manned landing on the moon, and neither does the whole world."

"This is the most cutting-edge field, and we don't know as much about Mars as we do about the moon."

"My suggestion is that we can first arrange for an unmanned space shuttle to conduct an experiment and collect some data, and then start the manned landing project."

"Come on directly. Isn't this a bit too hasty?"

Xu Chuan shook his head and smiled: "No."

"Landing on the fire and landing on the moon are two completely different concepts. The distance between the Earth and Mars is too far, and we don't have many opportunities to waste."

"Even if we now have more advanced aerospace engine technology, it will still be affected by the window period to a certain extent."

After a pause, he continued: "As for experience, this is not a problem."

"The combination of a small fusion reactor and an aerospace engine gives us enough room for error, whether it is fuel life or the amount of supplies stored on the aircraft, which are unmatched by traditional chemical fuel launch vehicles."

"And in case of an unexpected situation, we now have enough rescue power to ensure the safety of astronauts."

"In addition, another key point is that the orbit between Mars and the Earth has changed too much."

"The orbit between the Earth and the Moon is relatively stable, and deviations will not be large, so the experience of unmanned probes and landers is very high."

"But the Earth is different from Mars in that its orbit is so different that it invalidates these experiences."

"This is also the stage we must go through when facing deep space navigation."

"After all, we can't just circle the orbit of the earth and the moon without stepping out. Mars is actually a pretty good springboard."

After hearing this, Chang Huaxiang probably understood that Xu Chuan was definitely going to carry out a manned mission to the moon this year, so he didn't persuade him.

Speaking of risks, there are definitely some.

The normal manned landing process should be like landing on the moon. After launching unmanned detectors and lander to obtain various data, the manned landing is then carried out.

But as Xu Chuan said, a space shuttle that uses fusion reactors to provide energy is extremely superior in terms of flight time, manned space, reserve supplies and other conditions, and its ability to cope with various emergencies is stronger than traditional spacecraft.

Coupled with the large amount of aerospace experience they have accumulated in the past two years, it is enough to promote manned missions.

And several space shuttles can ensure that even if an accident occurs, rescue can be completed. They indeed have the conditions for manned missions.

After nodding, Chang Huaxiang thought for a moment and said, "There is one more question."

"Well, you say."

After organizing his words, Academician Chang said: "We will definitely carry out projects like manned missions, but the lead must be the space agency."

"You know what I mean, if the state doesn't take the lead in this kind of project, we won't be able to do it."

"But there are no relevant plans from the space agency right now. I'm afraid you need to communicate with them in person, including funding and other aspects."

Xu Chuan nodded and said, "Well, there is no problem with this. I will communicate with the space agency in person."

"Okay." Chang Huaxiang nodded and continued: "In this case, I will start the preliminary preparations for manned landing."

Xu Chuan thought for a while and said, "I suggest that two space shuttles be used for this manned mission. This will be safer."

Hearing this, Chang Huaxiang immediately understood. He smiled and said, "Well, this is indeed possible."

After thinking for a while, he continued: "Let the two second-generation aircraft go, it is safer."

Xu Chuan asked curiously: "Aren't there only two in total at the moment? The time required for manned landing on the moon is much longer than landing on the moon. This time, even if it is the card window period, it will take at least two months. time."

"If the two second-generation aircraft are going to carry out the manned landing project, what about the moon? There are a lot of projects on the moon.

Chang Huaxiang smiled and explained: "The industrial production line of the second-generation aircraft is currently manufacturing the third one. It will be completed in early March next year. After another two months of testing, it should be enough to perform the task."

"Just let it take over the work of Hanhai and Xinghe, and the more stable Hanhai and Xinghe will be replaced to carry out manned landings."

"This will not delay the development of the moon too much."

Xu Chuan nodded and said: "Then it's decided. The work of manning the mission will again trouble you, Chang Lao."

Chang Huaxiang waved his hand and said with a smile: "This is something that others can only dream of."

His eyes fell on Chang Huaxiang's half-white hair. Xu Chuan couldn't help but persuade: "The lunar surface project and manned missions are troublesome tasks. Find someone to share them with. You haven't seen me in the past few months. You are tired." It’s already changed.”

Chang Huaxiang nodded and said with a smile: "That's for sure. If you don't tell me, I will find someone to help."

"The lunar biosphere project, the outpost scientific research station base, the lunar mass orbit projector, and a manned mission to the moon. Each of them is a super project. How can I be busy?"

After a pause, he continued: "Actually, I no longer do some of the detailed work. There are people at the Aerospace Research Institute to share it, so don't worry."

Xu Chuan smiled and said, "Well, you still have to pay more attention to your health."

Although Chang Huaxiang said that he no longer does detailed work, commanding the overall situation consumes no less energy, or even more.

After all, each of the aerospace projects they are currently developing can be said to be a super project. The resource mobilization, work arrangements and other matters need to be fully considered, which can be said to be quite energy-consuming.

After chatting for a while about work arrangements in the aerospace field, Xu Chuan remembered another thing.

"By the way, there is one more thing about the aerospace engine."

"What's wrong with the aerospace engine?" Chang Huaxiang looked over and asked curiously.

Xu Chuan smiled and said, "I'm going to redesign it."

Hearing this, Chang Huaxiang was a little surprised and asked: "Huh? Redesign? Why, aren't the current aerospace engines pretty good?"

"It's pretty good, but I'm a little dissatisfied with the performance."

Xu Chuan smiled and continued: "You should know the news about room temperature superconducting materials."

Hearing this, Chang Huaxiang's eyes lit up and he quickly said: "Speaking of room temperature superconducting materials, do you have any extra materials over there? Can you get a piece for me to study?"

Confused by this sudden turn of events, Xu Chuan was stunned for a moment and then asked: "Aren't you a major in aerospace? Are you also researching materials?"

Chang Huaxiang said with a smile: "I came from Beihang University. Materials science and engineering is a national specialty there. It is top-notch. I have studied some. Although it is not as good as the majors, I understand it more or less."

After a pause, his face was full of interest, and he added: "Besides, this is a room temperature superconducting material. It's good to see what it looks like."

Hearing this, Xu Chuan couldn't laugh or cry for a moment: "Okay, I'll ask the Sichuan-Hai Materials Research Institute to send a piece over in two days."

He really didn't expect that this always calm old academician would have such a moment of escape.

"Oh, by the way, you just said that you want to redesign the aerospace engine? How? Use this new room temperature superconducting material?"

Finally remembering the business, Academician Chang asked.

"Well, it has a certain relationship, but it's not very big."

Xu Chuan shook his head and replied that room temperature superconducting materials are indeed one of the options to change the aerospace engine in the future, but what he wants to talk about today is not this, but another technology.

"Huh? What do you say?"

Hearing this, Chang Huaxiang had an interested look on his face. He originally thought that Xu Chuan wanted to use room temperature superconducting materials to redesign and manufacture the aerospace engine to improve the performance of the aerospace engine.

Now it seems that he guessed wrong?
