July 20th, 50th anniversary of the first man landing on the moon. The moon had for years been just a brightly illuminated disk in the sky, changing the shape for sunlight that is different from it. True, the United States and the Soviet Union have made the Moon more than ever, the goal and the symbol of victory.
The first was sent to the probes, and later to the people. Far from the heavenly body, in the end, it became a real, tangible world that successfully traveled 384,000. 400 kilometers, but we might know better.
Scars of comets and asteroids
On the surface of the Moon there are many craters. It is estimated that their age is about 4.1 to 3.8 billion. years. The largest lava flooded lava formed the "sea".
Craters are the "scars" left by comets and asteroids. It is believed that many lunar craters formed during the late space bombing, compared to 4.1-3.8 billion. many years ago, when many asteroids fell into the inner part of the Solar System. Some hundreds of miles in the center of the lunar craters have "spikes", peaks, and their edges surround the remains that left the crash.
It is interesting that lunar shakes often appear at a depth of several kilometers on the moon. It is believed that the thickness of the lunar cortex is uneven, and the melting point may vary from the least 12 km. Usually the thickness is about 50 km.
It is believed that a molten masonry layer lies in the 330 km radius beneath the mantle. Here the temperature should be 1400 ° C. It is said that the Iron Moon radius is about 240 km. Only 2-4% is left to him. Moon Moon. Planetary cores are much more difficult.
Theory of lunar phenomena
It is estimated that about 4.4 billion Protoplanes of Mars size, 4 km / sec. speed, obstructed the Earth. The collision was so strong that the iron nucleus of the teapot (protoplanet) was floating to Earth, and the cloaks of both planets clashed.
Not all parts of the planet and debris are mixed. Part of the mantle emerged on the Earth's orbit. These particles later joined the object we now call the Moon. The gravity of planetary collision has destroyed the circular universe, the satellite of our planet.
There is no wind in this cosmic body, there is no erosion, only fine micrometers of a mild tonic surface. Although the Apollo astronaut's scientific equipment captured certain seismic waves of Moon's earthquake, this cosmic body is essentially inactive. It is believed that the most exciting period of the moon was 3 to 4 billion years ago when the inner part of the Solar System was bombed with comets and asteroids.
The moon is constantly moving
Although it seems that the moon is not great at night, but measured its diameter (distance from one side to the other), you get a distance of 3475 km. Approximately one kilometer is Vilnius and Madrid.
Surprisingly, it is called the phenomenon when Menulis approaches the Earth. 59% of our planet is visible. Month.
The moon was visited by 12 people who brought 382 kg of lunar rocks. If the Earth was a basketball ball, and the moon was a tennis ball, those facilities would be 7.3 meters away.
It is also interesting that the Moon from Earth travels through 3.8 cm per year. It is believed that the distance from Earth was 22,530 km.
Human intriguing lunar phases
The moon turns around its axis and circles around the Earth, so that the Moon's day is almost the same as the Moon of the Earth. The moon always turned to us from the same side, so we can see how its surface slowly falls at night. People call it a moon phase change.
Moreover, the floods on our planet determine the gravity of the Moon and the Sun rotating around the Earth. Our cosmic satellite pulls large water bodies to itself, creating two floods per day. Perhaps in the future this statement will be supplemented by scientists.
When it's near the moon, we say the moon is full.
When the Moon enters the Earth's shadow, the Moon's Pombrina begins. The satellite becomes dark, sometimes bloody. When the Earth enters the shadow of the moon, sunset begins and the day turns into a few minutes at night.
The partial solar eclipse occurs when the moon is "spilling" against the Sun. Because of the distance between Earth and its size (the Sun is bigger but still, and the Moon is smaller but closer), the Moon Shield can cover the Sun perfectly.
The last man and the discussion about the return
The last person on the moon, Geneas Cernan from Apollo 17, did it in 1972. Since then, there have been several plans to return, but all have been canceled.
However, NASA develops a space launching system that will work with a powerful rocket. This new missile would no doubt bring people back to the nearest neighbors of our planet. The Chinese are also interested in the possibility of such a flight, but it is not yet known when the person will return to Earth.
In addition, it is believed that, when it comes back, it will be the person who will move around because the satellite will try to accommodate it.
