Chapter 581: Deviation of moon landing point

During the entire Spring Festival, the most exciting thing is not the Spring Festival Gala or the Chinese Lantern Festival, but a key part of the United States' "return to the moon plan", which is called the "Pathfinder" probe by NASA. According to NASA's constant omission of details, this time

The mission of the 'Pathfinder' detector is threefold.

The first is the 'Pathfinder' probe, as its name suggests, to find a path for NASA to return to the moon from the earth, and to verify a series of technologies.

The second is the 'Pathfinder Probe'. The most important thing is to prepare for NASA's return to the moon at the end of 2026. It can be regarded as a prelude to NASA's manned lunar landing. As long as this mission is a complete success, it means that the United States is also capable of putting it to the moon.

Astronauts are sent to the moon and brought safely back to the surface of the earth from the moon.

The third is that the 'Pathfinder' probe will conduct mission detection on the lunar surface to further accumulate NASA's research on the moon.

Although this was not a manned moon landing, it still attracted worldwide attention. Under the overwhelming publicity of the major media, it was known to the whole world, as if this was not the launch of a lunar probe, but a manned moon landing, and it was a complete success.

.

The 'Pathfinder' probe was successfully launched and successfully entered the Earth's orbit 12 minutes later. After flying around the Earth for one and a half times, the probe entered the Earth-Moon orbit. After more than three days of flight, the probe flew past the Earth-Moon Lag.

The Langi point is only 28,000 kilometers away from the moon.

Then, the 'Pathfinder' probe flew over the lunar surface. After 11 hours of flight, the probe began to separate. A communications satellite orbited the moon in synchronous motion. This communications satellite will continuously transmit data to the moon.

When the detector is launched back to the earth, NASA's ground command center can also control the detector through two communication satellites orbiting the earth and the moon.

This communication satellite will also play a major role in NASA's manned moon landing.

Finally, after 102 hours and 45 minutes starting from the time of launch, the probe finally successfully landed on the front side of the moon.

It's just that although NASA promoted this as a huge victory, what makes the world a little weird is that the whole world watching the report of the 'Pathfinder' detector was not NASA, but China.

From launch to successful landing on the lunar surface, the entire process was captured by relevant Chinese satellites. The clarity of the videos and photos was much higher than what NASA announced, and the speed was even faster.

News has a characteristic of timeliness. The sooner someone can report it, the greater the value of the news and the greater the sensation it will cause.

As a result, many live broadcasts and special reports were watched by Chinese media, rather than American TV stations.

"We can see that it took NASA more than three days to move from the earth's orbit to the moon's orbit, while China's time was far less than this time. From this point of view, the China Space Administration chose

The Earth-Moon migration orbit is superior to NASA."

"We have seen that when the probe landed on the lunar surface, the 'Pathfinder' probe experienced obvious bumps, and the probe even turned over. However, starting from the Chang'e 4 probe, China's probe has landed very steadily.

.”

"It's over. There was an error when the 'Pathfinder' probe deployed its solar charging sail. If this problem is not solved, the launch value of the 'Pathfinder' probe will be discounted by at least 30%!"

"..."

Major Chinese media have carried out special reports one after another, and even some key nodes have been broadcast live, comprehensively comparing the 'Pathfinder' probe with China's previous lunar probes and the 'Chang'e' spacecraft during the manned moon landing.

contrast.

Comparisons were made from the time of migration between the Earth and the Moon, the status of the probe's landing, etc., and even the communications between the Earth and the Moon were compared in detail.

And every comparison brings a 9999-point critical blow to the confident people of North America, especially when they find that no matter how much they boast about their own 'Pathfinder' detector, it is an indisputable fact that the time is much longer than that of China.

, and the signal lag of our own detectors returning to the earth is very serious.

However, the 'Pathfinder' probe successfully landed on the lunar surface and began its detection mission. This is definitely a success. The number of people who can do this is not more than a slap in the face.

Since the "return to the moon plan" failed a few years ago, the "Saturn V" turned into a ball of fire, like extremely brilliant fireworks, and the "Chang'e" spacecraft successfully achieved manned landing on the moon, then even the most stubborn people

, sa is temporarily ahead of nasa in the aerospace field.

Qin Yuanqing also kept paying attention to NASA's "Pathfinder" detector. He easily mobilized China's communication satellites and the detectors all the way to detect the "Pathfinder" detector's detection data. Qin Yuanqing found out about NASA's earth-moon migration.

It is very conservative and basically follows the orbit of the earth and moon that they launched probes to the moon and recorded by the legendary Apollo in the past, without optimizing and choosing a new route at all.

NASA's suffering this time was not only reflected in the migration of the earth-moon orbit, but also in the landing of the probe on the lunar surface. After the probe completed seven circles around the moon, it then began to land on the lunar surface.

However, Qin Yuanqing still keenly discovered that NASA's technical experts were indeed in a hurry. The moon landing point was a bit far away, and it was probably more than ten kilometers away from the moon landing point calculated by NASA at the beginning!

The moon landing point is a great test of the capabilities of aerospace technicians, as well as the operational control capabilities of engineers.

China's 'Chang'e' series of detectors and 'Chang'e' spacecraft were able to achieve perfect landings because Qin Yuanqing's calculations were very accurate, and the calculation results were even accurate to ten decimal places. And engineers controlled the earth

They all follow the process and maintain a very high level of operation. This operation even takes into account the delay time in the transmission of information from the earth to the moon.

Don't think that the moon point is shifted by ten kilometers, but you must know that one of the missions of NASA's "Pathfinder" probe is to have a small life module to prepare for the subsequent manned moon landing. There is a small life module

The capsule and the subsequent manned lunar landing will allow the astronauts to stay on the lunar surface for a while longer. Otherwise, the astronauts will not be able to stay on the lunar surface for a long time relying on oxygen and anti-shooting suits.

For example, on Apollo 17, the astronauts landed on the moon three times, that is, after landing on the moon in the lunar module, they returned to the lunar orbit for resupply before the oxygen and other living supplies were exhausted. Three times, the total stay on the moon was

It is 74 hours, 59 minutes and 40 seconds, and the lunar travel time is only 22 hours, 3 minutes and 57 seconds.

These records are far inferior to those of the Chang'e spacecraft.

According to Qin Yuanqing's estimation, even if the United States successfully lands a manned man on the moon, it is estimated that the life system currently sent to the moon will not be needed.

"It seems that even if the United States does carry out a 'manned moon landing' this year, it will probably be another legendary Apollo mission at most, and it will probably not be able to make any new breakthroughs." Qin Yuanqing predicted in his mind.

From this 'Pathfinder' probe, combined with the BFR rocket, Qin Yuanqing has been able to almost calculate the situation of the next American manned moon landing.

In such a short period of time, it is estimated that the United States will not deploy relay satellites between the Earth and the Moon. As for quantum communication satellites, the United States’ quantum communication technology is still very average. Under such circumstances, it is necessary to build an Earth-moon communication system.

, the difficulty is very high. This can be seen from the signal of the 'Pathfinder' detector transmitted back to the Earth Command Center. The delay time is very obvious, very similar to the communication situation in China more than ten years ago.

Not to mention, an accurate landing and the deployment of more lunar rovers in advance.

Half a century ago, Qin Yuanqing did not dare to say absolutely whether NASA had landed on the moon, because at that time, the United States was also in the era of the Big Explosion of Science and Technology, with many great scientists and a group of experienced and creative engineers being born.

The United States invested a lot of money again. The entire Apollo program cost 25.5 billion U.S. dollars. At that time, the U.S.'s annual GDP was less than 1 trillion U.S. dollars, which was equivalent to more than 2% of GDP. At that time, the largest U.S. ship

Advanced aircraft carriers cost 4 billion US dollars. One Apollo project was equivalent to building more than 6 of the most advanced aircraft carriers at the time.

Therefore, from a certain perspective, it is possible for the United States to achieve a manned moon landing at that time.

Of course, NASA's manned moon landing may also be a Hollywood special effect, because it is full of too many mysteries. NASA has given explanations for these mysteries, but they are still unconvincing.

So many people think that all those classics are just special effects shooting in Hollywood studios, and those astronauts are just movie stars, not real astronauts.

After the Lantern Festival, the Spring Festival has almost passed, and people gradually transition from vacation to work, instead of fishing like the previous week, when everyone was listless and always thinking about celebrating the New Year.

It was also at this time that the superiors finally formally approved Qin Yuanqing's resignation as commander-in-chief of the 'Golden Crow Project' headquarters, and the red-headed document was made public.

What is very strange is that there is no name in the red-headed document as to who was appointed as the commander-in-chief of the "Golden Crow Project" headquarters.

Qin Yuanqing has already received the news that the 'Golden Crow Project' headquarters has not been maintained, but has been disbanded. Each deputy commander-in-chief has been newly appointed. Some have entered ministries and commissions to assume more important responsibilities, and some have gone to local areas to become feudal officials.

.

The original R&D personnel have basically completed their placement.

This is an important manifestation of strong organizational capabilities. A document has strong authority, allowing all units and people to implement it whether they want to or not.

Qin Yuanqing can also move away from the "Jinwu Project" and have a smooth start to the Narcissus Nuclear Power Plant transformation project. The next step is to accumulate experience and train more nuclear technicians and managers. When enough has been accumulated, it will not take many years for fusion to

Nuclear power plants can truly meet China's needs.

Even the surrounding border provinces can build a fusion nuclear power plant, which can not only meet the power needs of the province, but also provide power to overseas countries.

Electricity may seem cheap, but it is actually a very expensive energy source. One unit of electricity may only cost 30 to 40 cents to sell, but it cannot withstand large quantities. 100 billion kilowatt hours of electricity costs 30 to 40 billion yuan, and it is still a seller's market.

Rather than a buyer's market.

From a certain perspective, electricity, like oil in the past, is an essential energy source for industrial development.

The reason why electricity is not as important as oil is simply because there are only a handful of exports of electricity, and the amount is not large. The electricity generated by each country is not enough for its own use, and it is simply reluctant to supply electricity to others.

A very important reason why China can achieve industrialization is that China has established a large number of thermal power plants and hydropower stations. Otherwise, it would not be possible to achieve industrialization.

Looking back ten years ago, with the realization of lithium-air batteries, electricity consumption increased dramatically. China spent so much money to build large hydropower stations and nuclear power plants. This was because without solving the problem of electricity, no matter how good the lithium-air batteries were, they would be useless.

Look at some countries in recent years. Although they have also used new energy vehicles, as electricity consumption has increased sharply, power supply has been insufficient. As a result, power outages have continued to occur.

Although Qin Yuanqing resigned as the commander-in-chief of the 'Golden Crow Project' headquarters, he is still very busy, because anti-gravity technology and plasma engines have begun to enter a critical moment. The anti-gravity device has begun to enter the construction stage. Can it be stable, sustainable and effective?

Providing anti-gravity will be a focus this year.

Anti-gravity technology, creating anti-gravity is only one aspect, whether it can be effectively controlled is another dimension.

Power is good power only if it is mastered by human beings!

Otherwise, this is a double-edged sword. The front foot plays a huge role, and the back foot will become a huge disaster.

The same situation also exists with the plasma engine. Whether the plasma engine can operate safely and be controlled accordingly will determine whether the aerospace fighter can officially make its first flight successfully.

The plasma engine is equivalent to an aerospace engine. Before it is mounted on an aircraft, experiments, tests and inspections are required. Only by ensuring that there are no problems at all and mounting it on an aircraft can the aerospace aircraft succeed in its first flight.

Otherwise, if the plasma engine fails, it will be fatal to the aerospace aircraft just like the failure of the aeroengine of the aircraft. It can easily lead to the aircraft crash and the loss of life.

This year the project department will build a large plasma engine and conduct tests. Problems will be found and solved during the experiment. Next year, three plasma engines will be built at once and tested.

Of course, the most important thing is that there is an important task this year, which is to compile the second manned lunar landing mission, and to start training and selecting astronauts for the second manned lunar landing, so as to prepare for the second manned lunar landing mission in the coming year.

Preparations for man to land on the moon.

A manned moon landing is a distance of 380,000 kilometers, and there are a lot of unknown dangers. The cost of a manned moon landing is billions of dollars, and more importantly, astronauts. Once there is a loss, it will be directly

The loss is billions of yuan, or even tens of billions of yuan. It is definitely a heavy loss, and no link can be lost.
