Anonymous users2024-02-11On January 30, the National Aeronautics and Space Administration (NASA) used the Lunar Reconnaissance Orbiter (LRO) to photograph the landing site of China's Chang'e-4 probe. On Wednesday, researchers at the agency posted the photo on the mission blog of the Lunar Reconnaissance Orbiter.
The U.S. "Business Insider" ** issued an article on the 6th, saying that a month after China completed the historic Chang'e-4 moon landing mission, NASA released a **, further proving that this feat was successful.
NASA scientists found the lander and lunar rover in the ** below, which was taken on January 30 with a yellow arrow pointing to the landing site, according to the article. Recently, the National Aeronautics and Space Administration (NASA) released a **, which further proves that the Chang'e-4 moon landing was successful, and the vehicle was more than 330 kilometers away from the landing site when it took this **, which made the Chang'e-4 lander "only about two pixels wide", and "the small lunar rover cannot be found in ** at all". It is worth mentioning that this is not the first time that NASA has used a lunar reconnaissance orbiter to study China's lunar landing.
On December 30, 2013, scientists also used the vehicle to locate China's Chang'e-3 probe on the lunar surface. Lao Mei has been staring at China's every move, NASA shows the world the Chinese moon rabbit! I believe that soon, you will be able to photograph China's five-star red flag planted on the moon!
Not long ago, the news of China's successful landing of Chang'e-4 on the far side of the moon caused a sensation in the world, and while people were excited and excited about the progress of mankind's lunar landing, there were also many "well-intentioned people" who were angry about the rapid development of China's aerospace industry, and even did not hesitate to spread rumors to slander us.
Recently, foreign media unexpectedly appeared in a report entitled "China's release of the moon ** proves that Chang'e-4's landing on the moon is a fake, because someone found a mysterious chalk line"!
However, before we could personally refute these ridiculous remarks, NASA stood up and "slapped these rumors in the face".
"Chang'e-4 landed safely on the plains of the von Kármán impact crater on January 3," NASA scientists issued a statement, while also unveiling satellites from the Chang'e-4 landing site**.
I don't know if the statements issued by the authorities will be able to silence the rumormongers.
Perhaps it is because some people feel threatened by the fame of China's national prestige all over the world, so these uncontrollable rumor-mongers have never stopped smearing China.

The landing site is on the far side of the Moon.
Von Kármán crater in the Antarctica-Aitken Basin.
At 10:26 on January 3, 2019, the Chang'e-4 probe autonomously landed in the Von Kármán impact crater in the South Pole-Aitken Basin on the far side of the Moon, achieving the first soft landing of a human probe on the far side of the Moon.
Von Kármán. The crater is located in the middle of the Aitken Basin at the far side of the Moon's South Pole, which is the entire solar system.
The oldest impact crater, which was smashed by a meteorite about 4 billion years ago and is no less than 3.6 billion years old, preserves the rocks of the original lunar crust and may contain water, which is of great scientific value.
On February 4, 2019, the International Astronomical Union approved the naming of the ** peak in the von Kármán pit where the Chang'e-4 land site is located "Mount Tai".

Feng. The Carmen crater is a huge ancient impact crater with a diameter of about 180 km. It was formed about 100 million to 100 million years ago.
Famous Hungarian-American engineer Theodore. Feng. Carmen was named.
It is worth mentioning Feng. Carmen was Qian Xuesen's teacher.

Anonymous users2024-01-30DecideChang'e-5 probeThe landing site is the Rumke Mountains.
Because this place is more suitable for landing, it is a pre-selected landing area, fromChina National Space AdministrationIt was learned that at 23:11 on December 1, 2020, the Chang'e-5 probe successfully landedMoonThe pre-selected landing area near 51 8 degrees west longitude and 43 1 degrees north latitude was frontal, and the landing image was sent back.
According to the China National Space Administration, at 22:57 on December 1, the Chang'e-5 lander and ascender combination began to perform a dynamic descent from about 15 kilometers from the lunar surface, and its final landing site is located in the area north of the Lumke Mountains in the Lunar Front Storm Ocean.
This is a place that human probes have never visited before. It is surrounded by a 1,300-meter-high volcanic group, and the environment is truly steep, making the Chang'e-5 trip even more adventure-like.
Previously, the American Apollo program.
More than 380 kilograms of lunar samples were brought back from the moon, and the Soviet Union relied on unmanned aerial vehicles to obtain a total of more than 300 grams of lunar soil in three times. However, spacecraft from the United States, the Soviet Union and other countries have not visited the vicinity of the Lumke Mountains.
July 20, 1969 20:17:43, talking about Apollo 11.
The spacecraft landed in the Moon's Still Sea.
Region. American astronaut Armstrong.
A deep imprint was placed on the surface of the moon, which was the first successful landing of man on the moon. To commemorate this exciting occasion, July 20 is celebrated as Human Moon Day every year.
However, the Apollo program's greatest contribution to science was not Armstrong's footprints, but the return of rocks from the moon. From 1969 to 1972, the United States completed six manned lunar landings, bringing back a total of about 382 kilograms of lunar samples and obtaining a large number of scientific results.
After half a century, China is finally going to collect lunar soil. According to the plan, China will launch the Chang'e-5 probe at the end of October 2020 to collect lunar samples and bring them back to Earth through shoveling and drilling.

Anonymous users2024-01-28The electromagnetic environment on the front side of the Moon is very different, and the electromagnetic environment on the far side of the Moon is very clean, shielding from radio signal interference from the Earth, and it is a dream place for astronomers to conduct low-frequency radio research.
Chang'e-4, equipped with a low-frequency radio spectrometer, can fill the gap in the field of radio astronomy in the low-frequency observation range, and will provide important data for the study of stellar origin and nebula evolution.
In February 2019, astronomers announced that they had discovered a star system with planets that could support life 39 light-years away. And in the nearby dwarf star "Trappe 1", seven Earth-like planets were discovered, and all of these planets may have water on their surface, which is one of the key components of life, which is also an important location for us to find extraterrestrial life, three of which have such good conditions, scientists say that life may have developed on it, so this may be the first area where extraterrestrial life is discovered, of course, there is water and there is not necessarily life, this still needs to be determined, it can only be said that there is this probability, or exist 39 light-years away.
It's true. This is the twin program launched by NASA, and they chose a pair of twins for this experiment. NASA sent her younger brother into space, while her older brother remained on Earth. >>>More
I think the answer is almost no, even if you have strong willpower, the result can only be that you will feel very tired after a few days of perseverance, and then you can't continue, and to be honest, your method of memorizing words like this is not good for learning English, you can try to be good sentences or paragraphs, so the effect may be better, but my personal opinion, it may not be good, don't mind.
Because the relative positions of the sun, the earth, and the moon are constantly changing, the part of the moon that people see on the earth illuminated by the sun's rays is also constantly changing, producing various different visual shapes, which are called moon phases. The phases of the moon include the new moon, the upper Xuanyue, the full moon, the Emei moon, the gibbous moon, the lower Xuanyue, etcWhenever the moon orbits between the sun and the earth, and the hemisphere illuminated by the sun is facing away from the earth, people cannot see the moon on the earth, and this day is called the "new moon", also called the "new moon", which is the first day of the lunar calendar. >>>More
It's better to start as soon as possible, gre words are very difficult, not you can memorize them once or twice, it is recommended to start as early as possible, and it's already September, it's not early, you still need to review other projects.
