When astronauts are on the moon, is the dirt under their feet dust?

The Moon does not have an atmosphere, so for hundreds of millions of years, the material on the surface of the Moon has not been blown up like the Earth. The ** of the surface dust is a meteorite impact. The main components are crystalline particles, larger igneous rock fragments, glass fragments, and trace metal particles.

In addition to this, various types of radiation in space also have an impact on this. The thickness of dust on the surface of the moon is between 3 and 20 meters. Of course, it's not as loose as we think.

Without air to blow them, the dust becomes very dense over time. Walking on the moon brings dust, which can easily attach to the body or instruments, causing a lot of trouble. There are now an average of 5 tons of meteorites hitting the moon every day.

It takes a total of ten minutes for the dust to rise and fall. Unlike Earth, the Moon has air, wind, and a strong gravitational pull. There is no air and wind on the moon, <>

With only one-sixth the gravitational pull of the Earth, it can be said that everything on the Moon will become very light. In the absence of external forces, the dust on the moon is shaken, and its state and form will not change. Because the gravitational pull is small, the dust will fly very high, and because there is no wind, there is no resistance, it will not be blown everywhere.

However, because dust itself has mass, when it flies to a certain height, it exhibits a free-fall motion and falls straight back to its original position! So don't worry about the dust flying all over the place! Lunar dust is composed of silicide that is similar to that of time, which is loose, delicate, fine, and easily charged for a long time.

The thickness of lunar soil is generally 5-10m.

Lunar dust is easy to fly under the interference of lunar rovers and humans, causing serious damage to the operation of space launch equipment and is extremely dangerous. When the surface of the moon is disturbed, dust will appear and fly higher and farther. The main cause of dust emissions is collisions.

Jingchen relies on external force to change its original static state and move towards the air. Without air, there is no air resistance. The gravitational pull of the Moon is one-sixth of that of the Earth.

will fly higher and farther. Although there is no air resistance, it will be assumed that it will fall quickly, but the gravitational acceleration is one-sixth that of the Earth, so the falling speed will be slower and it will look like it will float down.

In fact, it is not dust, it should be rocks in the strict sense, and the material is relatively special.

Yes, there is also dust on the moon, and it is dust under their feet.

Of course, this is some dust on the moon, although it is different from the earth, this dust is also worth studying.

It should not be the ordinary kind of dust on the earth, because the soil on the moon and the soil on the earth are not the same level of material.

The astronaut who left the first human footprint on the moon was Armstrong.

On July 20, 1969, the American Apollo 11 spacecraft landed safely on the moon. A few hours later, astronaut Armstrong landed on the moon, leaving the first human footprints on the moon. To commemorate the success of the first human landing on the moon, July 20 of each year becomes "Human Moon Day".

Introduction:

While serving at NASA, Armstrong became the first astronaut to set foot on the moon on July 21, 1969, and the first human member to leave footprints on an extraterrestrial body on Earth, while his partner, Buzz Aldrin, became the second person to return safely after landing on the moon, spending two and a half hours on the moon's surface.

Armstrong's first space mission was Gemini 8, in which he and David Scott made the first orbital docking in history.

Astronaut Armstrong became the first man to set foot on the moon, leaving a clear footprint on the moon, saying, "It's a small step for one person, but it's a huge leap for man." Neil Alden Armstrong is an American astronaut, test pilot, Navy pilot, and university professor.

So to speak.

The Moon does not have an atmosphere, so for hundreds of millions of years, the material on its surface has not been blown into a mess like the Earth.

The dust on the surface** is a meteorite impact. The components are mainly crystalline grains and large igneous rock fragments, vitreous fragments and trace metal particles. In addition to this, various types of radiation in space also have an effect on this.

The thickness of the dust on the surface of the moon is between 3 and 20 meters. Hail, of course, is not the loose dust we imagined. There was no air to blow them, and the dust was dense over the years.

Walking on the moon brings up dust, and this dust can easily attach to your body or instruments, causing a lot of trouble.

There are now an average of 5 tons of meteorites hitting the moon every day. This bumped up dust can rise and fall, taking a total of ten minutes.

On the surface of the moon there is a thick layer of dust-like powder, which is not dust, but volcanic ash left over from ancient times. There are no storms on the moon, volcanic eruptions, meteorite impacts produce large amounts of volcanic ash, and billions of years have passed and they still remain as they were.

The dust on the surface of the moon is not the same as the dust on our earth, the dust on the surface of the moon is produced by the impact of meteorites, and is mainly composed of crystalline particles and large igneous rock fragments, vitreous fragments and trace metal particles. The dust on the surface of the moon is similar to the silicide composition of quartz, they are extremely delicate, like powder, they are also easily charged, and can also remain charged for a considerable period of time, so the dust on the surface of the moon can float and move for a long time after being charged under the photoelectric effect and solar wind irradiation. Therefore, when there are external factors (such as lunar rover, astronauts) interference, there will be a lot of dust.

It is not useful now, because it will be useful in the future. Why do you say that? Because bringing lunar soil back to Earth is now symbolic, it has no impact on current research.

It cannot help scientific research on the moon on Earth. At best, it can only analyze the composition of lunar soil. To collect soil to get data, to get more data to determine if it's safe to fly, if we've done a lot of digging in the soil, and it's safe enough to return, that means our manned return technology is moving forward.

The Moon is our only natural satellite on Earth and its strategic commanding heights. "Hu Hao, chief designer of the third phase of China's lunar exploration program, said"Because the moon has its unique conditions, its location, environment, and resources are all very unique, which is conducive not only to the subsequent development of space technology and scientific understanding, but also to the subsequent development of economic and social construction.

By conducting on-site exploration and sampling of selected lunar landing areas, the Douchen provides more effective data for later lunar base siting, such as the environment and topography of the lunar surface, as well as the chemical and physical properties of lunar rocks and other materials. Secondly, as the first celestial body to be detected and sampled, by analyzing the composition of the lunar soil, it is possible to infer the formation process of the moon and look for memories of the movement and action of stars hundreds of millions of years ago"。Humans first explored the moon to study the Earth.

It's no joke. Because the moon has no atmosphere and no geological activity, human beings first explored the moon in order to study the earth. It's no joke.

Because the Moon has no atmosphere and no geologically active Zen meditation.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

It has a particularly important research value, so that we can understand the formation of celery on the surface of the moon, and we can understand whether the surface of the moon is suitable for planting mammoth-headed plants, and we can understand the nutritional value and composition of the soil. It can promote the development of science.

In this way, you can better understand the geographical location and environmental resources of the moon, and you can carry out follow-up development, and the promotion of the base will also help the follow-up construction. The composition of the soil can be analyzed, and the history of the moon can also be learned.

This can help the subsequent construction, so that we can understand the resources of the moon, we can understand the composition of the soil, and we can also understand the environment of the moon and the moon. It can be suspicious to promote the development of science and technology.

The astronaut who left the first human footprint on the moon was Armstrong. Neil Alden Armstrong is an American astronaut, test pilot, Navy pilot, and university professor. While serving at NASA, Armstrong became the first astronaut to set foot on the moon on July 21, 1969, and Yanhu was the first human member to leave footprints on an extraterrestrial body on Earth, and his partner Buzz Aldrin became the second person to return safely after landing on the moon, staying on the surface of the moon for two and a half hours.

Neil Alden Armstrong passed away on August 25, 2012, at the age of 82 due to complications following heart bypass surgery. In a statement, the family said Armstrong died of complications following heart bypass surgery in early August. Obama ordered on the 27th that the national flag will be lowered at half-mast on the day of the funeral of Armstrong, the first astronaut who successfully landed on the moon, to pay tribute to this legendary figure and express condolences.

After the news of Armstrong's death was announced, people in the United States and around the world also remembered the moon pioneer in various ways. NASA's Institute of Lunar Science called on the public to "wink at the moon" and pay tribute to him through the Internet.

In 1955, Neil Armstrong joined the Lewis Flight Propulsion Laboratory of the National Aeronautical Technical Advisory Board (later NASA) and later served as a test pilot at the Commission's Edwards High-Speed Flight Station in California. From 1962 to 1970, he was an astronaut at the National Aeronautics and Space Administration's Manned Spacecraft Center in Houston. In March 1966, he was the special pilot of the Gemini 8 spacecraft.

On July 16, 1969, he flew to the moon aboard the Apollo 11 spacecraft with Aldrin and Michael Collins (of whom he served as commander). On July 20, Armstrong piloted the "Eagle" lunar module to land on the surface of the moon, and at about 10 p.m. U.S. time that day, he and Aldrin stepped out of the lunar module and stepped onto the lunar surface. Armstrong was the first to set foot on the desolate and silent land of the moon, becoming the first man to land on the moon and walk on it.

At that time, he uttered a famous quote that has since been quoted on countless occasions: "It is a small step for man, but it is a giant step for humanity." "They spent 21 hours on the moon, took off from the moon on the 21st, and returned to Earth on the 24th.

In the same year, he was awarded the Order of Freedom.
