Rebirth 2008: I Can Make Money Reading

five days later,

Kongtian-1 left the Xinghuan space station and returned to Earth smoothly.

After the aerospace plane returns to Earth, there is a lot of work to be done.

For example, analyze and evaluate various data collected during the flight test, including the test results of various indicators such as flight performance, load capacity, and fuel efficiency, to determine the overall performance of the aircraft.

Check the aerospace aircraft for any malfunctions or problems during flight and carry out necessary repair and maintenance work.

It is also necessary to verify various performance indicators during the flight test to ensure that the performance of the aircraft meets the design requirements and expectations.

At the same time, other work may be required, such as aircraft maintenance and maintenance, personnel training and technical support, etc., to ensure that the aerospace aircraft is in the best condition before it is officially put into use.

After this test flight, some results were also calculated.

For example, in the case of standard load fuel, propellant and full load, the fuel cannot meet the needs of Aerospace-1 to travel to and from the moon, and it is necessary to replenish fuel or propellant on the Halo space station, mainly liquid oxygen and liquid hydrogen.

Due to the thin air on the moon, afterburning turbofan engine power is used, and only liquid oxygen can be used.

Xinghai Group has optimized the afterburning turbofan engine, which can be powered by liquid oxygen and fuel.

On May 15th, Mu Yang got the flight test report of Kongtian-1.

In general, there are no major problems, and Sky One is ready to take off at any time.

This result made him very satisfied. If major maintenance is carried out after one flight, the cost of use will be very high.

Sky-1 passes through the atmosphere at high speed, and the surface temperature of the fuselage is very high. If there is a problem with the cooling system, accidents are most likely to occur.

May 16,

Mu Yang came to the aerospace aircraft research institute to hear about Han Li's plan for landing on the moon.

Han Li held a meeting. The leader of the meeting was Mu Yang, and the other people were the management team of Space Exploration Technology Project Group 1.

"Chairman, according to the situation of the lunar probes sent out, and for the convenience of research, navigation and description of the characteristics of the lunar surface, and different regions may have different geological histories and resource distributions, we have carried out the geographical location of the moon according to the latitude zone. not according to the international division method." Han Li opened the PPT, and a photo of the moon appeared on the screen.

The photos of the moon were not stolen from others, but were taken by the Xinghai Group's lunar probe.

The distance between the two planets is about 384,000 kilometers. Of course, the orbit of the moon is elliptical, so the distance from the moon to the earth will vary. At the furthest point, the distance between the moon and the earth is about 406,000 kilometers, and at the closest, the distance is about 366,000 kilometers.

The Xinghai Group's probes can fly at a speed of 10 kilometers per second. According to this speed, starting from the earth, they can reach the moon in more than ten hours.

The difference between the shortest distance and the longest distance is about 40,000 kilometers. If Xinghai Group wants to land on the moon, it does not have to wait until the moon is closer to the earth before landing. This is too troublesome for frequent moon landings.

Mu Yang nodded: "Well, let's continue."

Han Li said: "We take the meridian of the center of the moon as the starting point, and plan to land at the equator (0°N) and 1.5° east longitude (E), where the terrain is flat and may have scientific research value.

The time is set to be 15 hours after the sun lands on the moon. At this time, the temperature on the surface of the moon has dropped to about 30 degrees Celsius, which is suitable for people to leave the cabin.

This time point is at eleven o'clock in the morning on June 20th. If we miss this time point, we will have to wait for a lunar day and wait until July 16th before we can take off. "

The moon also rotates, but one side of the moon is always facing the earth, while the other side is always facing away from the earth.

The side facing the earth is called "front side", or "Yue Zheng" for short;

The side facing away from the earth is called the "back side", or "lunar back" for short.

The position of the moon is relatively smooth because the earth blocks the meteorites, while the back of the moon is directly impacted by space meteorites, so it looks bumpy.

If the Xinghai Group wants to build a moon base, of course it should be built at the exact position of the moon, avoiding the flow of meteorites as much as possible.

The moon's rotation time, that is, the daytime is 27.3 Earth days, that is, the daytime and night time are almost 14 Earth days. The length of day and night depends on the revolution, which is the same as the earth's revolution.

If Xinghai Group misses the time, it will be postponed for almost a month.

For the first time to land on the moon, Xinghai Group chose a safer place and time, step by step.

It is also impossible to fly directly to the back of the moon and land on it. Many science fiction novels describe aliens on the back of the moon, because there is too little knowledge of the moon.

Several countries have launched lunar probes to observe the surface of the moon. The back of the moon is full of potholes. After zooming in, there are continuous circular mountains, and the deepest part is more than 8,000 meters.

Of course, if the Xinghai Group builds a base on the far side of the moon, if countries don't launch probes or interstellar satellites to observe, they will have no idea of ​​the Xinghai Group's actions.

"Is it too late at this point? If you are not ready, you can delay it." Mu Yang said worriedly, this landing on the moon requires two groups of four pilots and a dozen scientific researchers.

The purpose of preparing two groups of pilots is to prevent accidents for some pilots, and other personnel will not be able to fly the aerospace plane.

It is possible to control the space plane by flight, but the distance between the moon and the earth is still very far, and the signal delay is more than two seconds. Generally, the flight control will not be used.

Han Li said affirmatively: "Yes, we have made all preparations, the lunar module has been tested, and the intelligent mining robot..."

"That's fine. Follow the plan. Let's set the moon landing on June 20."

For this day, Mu Yang has been preparing for many years.

Half an hour later, the meeting ended.

Three days later, on May 19th.

Xinghai Group announced: "Our company will land on the moon on June 20, 2020!"

Just one line, no more plans.

But this line of words caused waves all over the world.

The Xinghai Group has already developed an aerospace plane. In the past few days, reports about the aerospace plane have been dominating various websites. The world has been overwhelmingly discussing how things are going on in the interstellar world. It has aroused a lot of attention on space research, and there are relatively few celebrities and gossip news.

"Since ancient times, it has been believed that the moon is an inseparable part of our country. Is the Xinghai Group planning to occupy our land?" A netizen from a certain country commented. They don't like to see Hua's space technology is more advanced than theirs, let alone too advanced. I don't know how many years have passed.

"Nonsense, the moon originally belonged to the country of Hua, and Chang'e can testify!" Hua country's netizen retorted.

"I am looking forward to being the first private enterprise to land on the moon. If the moon recruits workers, I will be the first to sign up."

"From today, moon mining workers and construction workers are the highest-end occupations."

The media from various countries made grand reports on the Xinghai Group's plan, as did various domestic TV stations.

When Mu Yang returned home, the two children also asked him: "Dad, are there any monsters on the moon? My classmates said yes, but I said no, they didn't believe it!"

Mu Xiaoxi and Mu Xiaofan, who have already finished the second grade of elementary school, have a much higher IQ than their peers.

Education in Jiangnan Province is relatively complicated, and most of the children who study in Xinghai Group schools have parents who graduated from prestigious schools, so these children are smarter than most of their peers.

However, these "other people's children" are still crushed by Mu Yang's children.

The teaching materials of Xinghai Group schools are somewhat different from those of other schools in H City, and children are required to master more scientific knowledge.

In addition to language, mathematics, and English, primary school textbooks in Jiangnan Province also include general knowledge, sports, labor, art, music, computers, etc.

The Xinghai Group School also requires students to learn simple programming, office software, scientific experiments, etc., and the teaching adopts bilingual teaching.

This is not to give children heavy tasks, but these children are smarter. If you don't do this, the children will appear too idle.

Like Mu Yang's children, in terms of language, English communication is basically barrier-free. Since this summer vacation, they have mixed into the company's laboratory to watch scientific researchers work.

In addition, they also intend to participate in charity activities.

"From the current point of view, our researchers have not detected any organisms. The extreme environment on the moon is not suitable for organisms to survive." Mu Yang explained to the child seriously, "When the temperature is the highest during the day, it can reach more than 100 degrees Celsius. The temperature is higher than the temperature of boiling water."

"Father, do you mean the temperature of boiling water at a standard atmospheric pressure? I heard from an uncle that when the air pressure is high enough, the water temperature can reach two to three hundred degrees Celsius." Mu Xiaofan scratched his head, a little curious.

"Yes, under standard atmospheric pressure, the boiling point of water is 100 degrees Celsius. If it is vaporized..." Mu Yang explained patiently that the child was absorbing knowledge, and he could not show a trace of impatience, so as not to dampen the child's interest in learning.

The company is growing and the kids are growing fast.

Time passed slowly, and the Xinghai Group was counting down to the moon.

30 days,

20 days,

10 days,

3 days

...

Global attention.

On the last day, the Xinghai Group officially announced the specific plan for this moon landing, who will land on the moon.
