five days later,
Kongtian-1 left the Star Ring Space Station and returned to Earth smoothly.
After the aerospace plane returns to Earth, there is a lot of work that needs to be done.
For example, various data collected during the test flight are analyzed and evaluated, including test results of flight performance, load capacity, fuel efficiency and other indicators to determine the overall performance of the aircraft.
Check whether any faults or problems occur during the flight of the aerospace aircraft, and perform necessary repair and maintenance work.
It is also necessary to verify various performance indicators during the test flight to ensure that the aircraft's performance meets the design requirements and expectations.
At the same time, other work may be required, such as aircraft maintenance and upkeep, personnel training and technical support, etc., to ensure that the aerospace aircraft reaches its best condition before it is officially put into use.
After this test flight, some results were also deduced.
For example, under the conditions of standard load fuel, propellant and full load, the fuel cannot satisfy Kongtian-1's round trip to the moon, and fuel or propellant needs to be replenished on the Star Ring Space Station. The main replenishment is liquid oxygen and liquid hydrogen.
Since the lunar air is thin, liquid oxygen can only be used to power the afterburning turbofan engine.
Xinghai Group has optimized the afterburning turbofan engine so that it can be driven by liquid oxygen and fuel.
On May 15, Mu Yang received the test flight report of Kongtian-1.
Overall, there is no big problem and Kongtian-1 can take off at any time.
This result made him very satisfied. If major maintenance was performed after one flight, the cost of use would be very high.
Kongtian-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 to land on the moon.
Han Li held a meeting. The leader attending the meeting was mainly Mu Yang, and the other people were the management of the Space Exploration Technology Project Group 1.
"Chairman, based on the situation of the lunar probes sent out, and in order to facilitate research, navigation and description of the characteristics of the lunar surface, and in addition that different areas may have different geological histories and resource distributions, we have conducted a geographical analysis of the moon's geographical location according to latitude zones.
Division, 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 40,000 kilometers. Of course, the moon's orbit is elliptical, so the distance from the moon to the earth will change to a certain extent. At its farthest, the distance between the moon and the earth is about 60,000 kilometers, and at its closest
At that time, the distance was about 60,000 kilometers.
The Xinghai Group's detector can fly at a speed of 10 kilometers per second. At this speed, it can reach the moon in more than ten hours from the earth.
The difference between the closest 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. This is too troublesome for those who require frequent landings on the moon.
Mu Yang nodded: "Well, go on."
Han Li said: "We use the meridian at the center of the moon as the starting point, and the planned landing site is the equator (0°N) and 5 degrees east longitude (E). The terrain here is flat and may have scientific research value.
The time is set 15 hours after the sun sets on the moon. At this time, the surface temperature of the moon has dropped to about 30 degrees Celsius, which is suitable for personnel to leave the cabin.
This time point is at 11 o'clock in the morning on June 20. If we miss this time point, we will have to wait for a lunar day and wait until July 16 before taking 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 the "front side", or "full moon" for short;
The side facing away from the earth is called the "back side", or "the back side of the moon" for short.
At the direct position of the moon, the moon is relatively smooth because the Earth blocks the meteorites, while at the far side of the moon, it is directly impacted by space meteorites, so it looks bumpy.
If the Xinghai Group wants to build a lunar base, it will of course be built at the full moon position and try to avoid the meteorite flow.
The rotation time of the moon, that is, the day time is 3 Earth days, that is, the day time 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 and took it 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. This is because they have 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 craters, and when magnified, there are continuous round mountains, with the deepest point being more than 8,000 meters.
Of course, if the Xinghai Group builds a base on the back of the moon, if countries do not launch detectors or interstellar satellites for observation, they will not know the actions of the Xinghai Group at all.
"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 will require two groups of four pilots and a dozen scientific researchers.
Two groups of pilots are prepared to prevent any pilot from having an accident. Other personnel will not be able to control the aerospace aircraft.
It is possible to control an aerospace plane by fortune, but the moon and the earth are still very far apart, and the signal delay is more than two seconds. Under normal circumstances, fortune control will not be used.
Han Li said affirmatively: "Yes, we have made all preparations. The lunar module has been tested, the intelligent mining robot..."
"That's ok, follow the plan and set the moon landing date on June 20."
Mu Yang has been preparing for this day for many years.
After half an hour, the meeting ended.
Three days later, May 19th.
Xinghai Group announced: "Our company will conduct a moon landing on June 20, 2020!"
Just one line, no more plans.
But it was this line of writing that caused a global stir.
Xinghai Group has developed an aerospace plane. In the past few days, reports about the aerospace plane have been dominating various websites. The world has been discussing the interstellar world overwhelmingly. It has attracted attention on space scientific research, but there has been relatively little attention on celebrities and gossip news.
"Since ancient times, we have believed that the moon is an integral part of our country. Is Xinghai Group preparing to occupy our country's land?" Netizens from a certain country commented that they did not like to see that Hua's aerospace technology was more advanced than theirs, let alone that it was too advanced.
I don’t know how many years passed.
"Nonsense, the moon originally belongs to Hua Kingdom, Chang'e can prove it!" Hua Kingdom netizens retorted.
"I am looking forward to being the first private company to land on the moon. If the moon recruits workers, I will be the first to sign up."
"From today on, lunar miners and construction workers are the most high-end professions."
Media from various countries have grandly reported on Xinghai Group's plan, as have domestic TV stations.
When Mu Yang returned home, his two children also asked him: "Dad, are there monsters on the moon? My classmates said there were, but I told them there weren't. They didn't believe it!"
Mu Xiaoxi and Mu Xiaofan, who have completed the second grade of elementary school, have IQs that are much higher than those of their peers.
Education in Jiangnan Province is inherently poor, and most of the children who attend 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" were still crushed by Mu Yang's children.
The teaching materials of Xinghai Group School are somewhat different from those of schools in H City, requiring children to master more scientific knowledge.
In addition to language, mathematics, and English, primary school textbooks in Jiangnan Province also include general knowledge, physical education, labor, art, music, computers, etc.
Xinghai Group School also requires students to know 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 relatively smart. If they don't do this, the children will seem too idle.
Muyang's children, in terms of language, have basically no problem communicating in English. Starting from this summer vacation, they went to the company's laboratory to watch the scientific researchers at work.
In addition, they also plan to participate in charity events.
"From the current point of view, our scientific researchers have not detected any living things. The extreme environment on the moon is not suitable for biological survival." Mu Yang explained to the children seriously, "When the temperature is the highest during the day, it can reach more than 100 degrees Celsius. This
The temperature is higher than boiling water.”
"Dad, when you talk about the boiling water temperature, do you mean 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, slightly curious.
"Yes, under standard atmospheric pressure, the boiling point of water is 100 degrees Celsius. If it vaporizes..." Mu Yang patiently explained that the child was absorbing knowledge and he could not show any impatience, lest it dampen the child's interest in learning.
The company is growing, and so are the children.
Time passes slowly, and the Xinghai Group counts down to the moon landing.
30 days,
20 days,
10 days,
3 days
…
Global attention.
Chapter completed!
