144. The speed of astronautics should be increased tenfold!
Back in Yandu, Xia Ming was sent to the newly built care room in the medical area as soon as possible, although he was lying down, he couldn't be idle for a moment, and he endured his physical discomfort and got busy.
Judging from the existing aerospace technology and Xia Ming's financial resources, it is not a fantasy to launch a probe to Zhishen, and Xia Ming had thought about having his own satellite before and made some preparations.
"Go to the Wisdom Star first? It's a great idea, and it's sure to be an instant hit! ”
In the AR vision, Xia Ming is talking to a thin middle-aged man wearing glasses thicker than the bottom of a beer bottle.
Lou Xinghai, 38 years old, born in an aerospace family, unwilling to be bound by the system, a few years ago, he took advantage of the wind of national policy to set up his own door, and wanted to become China's Space-X. It's a pity that reality has taught him that what Huaxia's aerospace system needs is not Space-X, but wants to throw out all kinds of dirty work with little technical content, and his company has been struggling on the verge of bankruptcy.
After Xia Ming intended to get involved in aerospace, he first looked for someone, and the first one found him. Lou Xinghai was unwilling at first, but after seeing Xia Ming's achievements in EI, he also realized that his original intention of jumping out of the system was to conduct research without restraint, so he agreed to Xia Ming's proposal to acquire his company.
Originally, in Xia Ming's planning, this aerospace company named "Kunpeng" and KunPeng in English will not be officially established until Lou Xinghai cleans up the beginning and end.
Now of course, it is burning eyebrows, Xia Ming not only wants Lou Xinghai to take the team to Yandu immediately, but also throws the task of designing the detector to him, asking him to come up with a rough design plan within three days. As for Kunpeng Company, it is up to You Kuang to go through the formalities.
After receiving this series of instructions, Lou Xinghai thought that Xia Ming's brain had burned out, but after hearing Xia Ming talk about the "Asteroid Belt Exploration Plan", he also burned it together. Of course, Xia Ming didn't explain the ins and outs to him, but just said that he wanted to make a big deal and make a name for himself as soon as possible.
Elon Musk's Space-X company completed the Mars landing exploration at the beginning of the year. Huaxia is also engaged in a series of Mars exploration operations, and Kunpeng Company wants to be a hit, so there is no need to go to Mars to join in the fun.
Xia Mingti's asteroid belt exploration plan is not only of great academic value, but also can create enough momentum in public opinion. The technology in this direction is very different from planetary exploration, which makes Lou Xinghai very excited.
Xia Ming hopes to launch a probe as soon as possible with the goal of Zhishenxing, giving the entire exploration plan a good start, and Lou Xinghai feels that this idea is very professional.
Four years ago, the American Dawn probe had already visited Vesta and Ceres, and Homo sapiens was mysterious. So far, humans have not seen it with their own eyes. The European Space Agency's "Dawning Project" has this idea, but the timeline is scheduled after 2030.
This idea has both technical value and public opinion value, as well as the technical reference provided by the Dawn probe, Lou Xinghai felt that Xia Ming understood aerospace, and he couldn't have imagined that it was just a beautiful misunderstanding.
"The total launch mass of the Dawn is only 1.2 tons, and the domestic Changsanjia rocket can be sent to the GTO (geosynchronous orbit). If you simplify the design, remove some unnecessary detection modules, and reduce the weight to 800 kg, you can directly send it to MEO (Middle Earth Orbit). The old man returns to the old. The technology is very reliable and cheap, and it now costs only 200 million, or 40 million dollars, for a single launch. Think about it. Which launch center has a looser launch table ......"
In Lou Xinghai's opinion, there are no technical difficulties in the whole plan, and he is more concerned about the launch. His previous designs have had successful launches. But that's just a small rocket. At most, it can only transport a few tens of kilograms to low-earth orbit, not to mention that it is not an opponent of the magnitude compared with the Chinese national team, Space-X, and even the Blue Origin company of Amazon boss Bezos.
"How long did it take Dawn to fly to Ceres? Eight years! I don't have eight years, not eight months, I hope to fly over in two months at most, plus the probe design, manufacturing and launch schedule, from now on, at most five months later, the probe will have to fall on Homo sapiens. ”
Xia Ming's response made Lou Xinghai stunned, he designed and manufactured a probe in three months and launched it into the sky, although this matter was suspenseful, it was not impossible, at least it was not a technical problem. But the probe will fly to Homo sapiens in two months...... Two months!?
couldn't touch Xia Ming, Lou Xinghai could only touch his forehead to see if he had a fever and auditory hallucinations.
"Up and down in two months, a few more days is fine", Xia Ming was like an iron rooster, reluctantly relieved. Lou Xinghai confirmed that he had no auditory hallucinations, and immediately overturned the conclusion that "Xia Ming understands aerospace".
"Xiao Xia, the Dawn was slowly moved by an ion engine, so it only took eight years. If you use chemistry to propulse, it will definitely not take eight years, but two months, which is too outrageous, do you know how far away Homo sapiens is from Earth? ”
Of course, Xia Ming knew that Xia Xiaoyan was his encyclopedia.
The perihelion of Homo sapiens is 2.13 AU from the Sun and the aphelion is 3.4 AU away. One astronomical unit is the average distance from the Earth to the Sun, which is 149.6 million kilometers.
Based on the plane formed by the Earth's orbit around the Sun (the ecliptic plane), the orbit of Homo sapiens has an inclination angle of nearly 35 degrees to the ecliptic plane, and the orbital period is as long as 4.6 years, so the distance from the Earth to Homo sapiens is not as simple as 2.13 or 3.4 minus 1.
Now Homo sapiens is about 3 astronomical units from the Earth, that is, 450 million kilometers, and the farthest distance from the Earth to Mars is only about 400 million kilometers. In previous Mars explorations, including the two-year operation, the probe flew for seven to nine months to reach Mars, and the distance was less than 60 million kilometers.
Xia Ming's request is equivalent to asking the probe to fly at an average speed of 104,000 kilometers per hour, which is almost ten times the current speed!
The current record for human space speed is held by Voyager 1, which was launched in 1977 and has flown to deep space almost 20 billion kilometers from Earth in more than 40 years, after many accelerations and many waves with the help of planetary gravity. In this way, the speed has only reached more than 60,000 kilometers per hour.
Xia Ming said very seriously: "The whole exploration plan is a show, since it is a show, you can't let everyone wait too long, it's best to be able to blind people at the beginning." ”
Lou Xinghai thought about it. didn't spit out the words "rich and capricious", but just sighed: "If you don't use black technology, you can't do it." ”
"Then let's go on", Xia Ming smiled: "I've read your paper, aren't you also trying Zhang Fulin's direction?" ”
Lou Xinghai paused for a moment, "Xia Ming also understands aerospace" The idea came back like a flying machine, and then added "It's a pity that it's just a Zhao Kuo".
He said with a bit of anger: "Since you know the VASIMR (variable ratio impulse magnetic plasma rocket), you should know where its technical difficulties are, and to put it mildly, it is a technical defect that cannot be overcome in theory." Give me a supercomputer that's ready to go. Coupled with a team of the best researchers in electromagnetic physics, in four months, I can verify whether this direction will work or not. As for practicality, four years is the most arrogant expectation if it is feasible. ”
"That's it, you hurry up and make a routine plan, let a probe fly over first, it can be regarded as a guarantee", Xia Ming seemed to regress. This made Lou Xinghai breathe a sigh of relief.
"As for VASIMR, you go to the institute, I give you the supercomputer, and the research team. But I'll only give you a month to verify the feasibility", Xia Ming's next words made Lou Xinghai stunned again: "It's not that I embarrass you, the supercomputer and research team you give are ten times more powerful than you imagined." ”
There was silence for a long time. Lou Xinghai sighed: "Okay, seeing is believing, I will fly over from Chang'an tomorrow." ”
“VASIMR? You're fighting too." Xiaotang's crisp voice sounded, and seeing that she was wearing a light green nurse's uniform and a towel on her arm, Xia Ming was surprised: "What about Xiao Huan?" ”
His brain is still in a state of "holding up to the limit", and he is digesting information little by little, and sending a sentence on a chat, or finding someone to pop up a window, is as laborious as waving his arms and stretching his legs. This made him return to the state of ordinary people, feeling very powerless and at the same time, there was a different kind of novelty.
Xiaotang shrugged: "That girl treats nursing patients as a play, she is tired enough during the day, I let her squint in the lounge for a while." ”
Xia Ming was bedridden, and Xiao Huan snatched the job of nursing, but she obviously didn't have the talent to be a nurse, and she couldn't bear it after tossing for most of the day.
"Lift your butt", Xiaotang wanted to wipe him with hot water and began to take off his pants.
"Uh......" Xia Ming was a little embarrassed, he had already been embarrassed once when Xiao Huan helped him wipe his body before, and now that he is replaced, his feelings are naturally different.
He had no choice but to take Xiaotang's previous words to cover up: "If you don't fight, you can't do it, the countdown in my head is always reminding me how much time is left, hiss......"
First it was cool, then it was hot, and the towel was covered on the vital point, and Xiaotang started from here.
"See you still say I'm small?" Xiaotang teased, reaching under the towel and making a little movement.
Xia Ming's breathing became cloudy, and the towel gradually rose up.
Looking at Xiaotang's cheeks, which were gradually dyed red, Xia Ming asked, "This is not small, right?" ”
Xiaotang glanced at him, the corners of his mouth hooked up a slight arc, and his movements increased a little faster.
Xia Ming was taken aback, aunt, you are doing evil!
Speaking of which, I missed the opportunity in the United States, and I had made an appointment to roll the sheets after returning home, but I got busy and had no time at all.
What is Xiaotang doing now? Don't you know that he doesn't have the strength to move the bullet?
Xiaotang's eyes were lowered, and he said in a floating tone: "You have some minor problems with your prostate, I checked your diet and your hygiene, and confirmed that it is not an infection, but a ......"
"Not really, right?" Xia Ming frowned: "I only ...... last month"
"Who are you dreaming about?" Xiaotang asked, and then let out a low breath, the towel was higher.
"Of course it's with you", Xia Ming was very distressed.
Xiaotang smiled, bowed his head and kissed him.
After parting his lips, Xia Ming protested: "You did it on purpose. ”
"Well, deliberately", Xiaotang didn't start, not letting him see his face: "Yang Yuanchang caught it, the truth was understood, and I was a lot more relaxed." I wanted to reward you with myself as a prize, but you are like this, I don't want to sit on it and move by myself, but this is my first time. So, so be it. ”
Let's just eat it as a dessert.
Xia Ming tossed and turned between tangled and comfortable, seeing that he was about to reach the end, the door was pushed open, and Xiao Huan walked in with a yawn: "Sister Xiaotang, I'm not sleepy, ah...... Belch? ”
Halfway through the yawn, he was cut off by the sight in front of him.
Seeing that Xiao Huan had no intention of retreating, Xiaotang sighed and smiled at Xia Ming: "Self-inflicted, don't live."
She naturally pulled out her hand and said to Xiao Huan, "Then I'll leave it to you." ”
When Xiaotang left, Xiao Huan came to the bed, stared at the towel that was still erected high, and muttered, "How can it be taller than that!?" ”
What can Xia Ming say? can only spread his hands innocently, and then he took another breath, and the hand under the towel was replaced by Xiao Huan's.
"Sister Xiaotang said, you need to ...... Well, relax, that's what I understand, right? Xiao Huan's face also turned red: "Or ......"
She lowered her head, not knowing whether it was shyness or what to prepare: "It's more comfortable to use your mouth?" ”
Seeing only the scene above Xiao Huan's head made Xia Ming's heart alarmed, and he hurriedly said, "No, no, no!" No more! ”
Xiao Huan raised her head, her delicate little face wrinkled, and she wiped it with a towel angrily.
Xia Ming looked at the ceiling speechlessly, this was really a sudden Shura field.
Xiaotang is right, he is self-inflicted, and he cannot live. (To be continued.) )
