Knowledge about the moon, knowledge about the moon knowledge about the moon

Tatsumi technology will bring great benefits to mankind. For example, the British company PPL has bred ewes with emphysema-I antitrypsin in goat's milk. The goat's milk sells for $6,000 a litre.

A ewe is like a pharmaceutical factory. What is the most effective and convenient way to expand the breeding of this sheep? The best way to do this is to "clone".

Similarly, the Dutch company PHP has bred cattle that can secrete human lactoferrin, and the Israeli company LAS has bred sheep that can produce serum albumin. How can these high value-added livestock be effectively reproduced? The answer, of course, is "cloning".

Mare and donkey can get a particularly strong heterosis animal-mule, but mules cannot reproduce offspring, so how can a good mule expand its breeding? The best thing to do is also "cloning". China's giant panda is a national treasure, but the success rate of natural mating is low, so it is on the verge of extinction.

How can this rare animal be saved? "Cloning" offers a practical way for humanity.

1. The moon seen by the human eye, also known as the moon, Xuantu, single juan and Pan Yu in ancient times, is the satellite of the earth and the fifth largest satellite of the solar system. The diameter of the Moon is about one-quarter of that of the Earth, and its mass is about one-hundred-eighty-one of the Earth's.

2. The Moon is the largest known satellite on Earth, and its surface is covered with craters formed by the impact of small celestial bodies. The average distance between the Moon and the Earth is about 384,400 kilometers, which is about 30 times the diameter of the Earth.

3. The Moon may have formed about 4.5 billion years ago. Soon after the formation of the Earth, there were several hypotheses about its origin. The theory, supported by more factual evidence, is that it was formed in the "Great Collision Origin Theory", which was formed by debris from a huge collision between Earth and a Mars-sized celestial body "Teyia" and gathered around Earth.

4. The moon revolves around the earth with a period of exactly the sidereal moon, so we can't see the back side of the moon. This phenomenon, which we call "synchronous rotation" or "tide locking", is almost a universal law in the world of solar system satellites.

The Moon, commonly known as the Moon and the Taiyin in ancient times, is a satellite that orbits the Earth. It is the only natural satellite of the Earth and the closest celestial body to the Earth (the average distance from the Earth is 384,400 km).

The Moon is the most thoroughly studied celestial body. The second celestial body that humans have ever visited is the Moon. The age of the Moon is about 4.6 billion years.

The Moon, like the Earth, has a layered structure such as a shell, mantle, and core. The average thickness of the outermost lunar crust is about 60-65 km. Below the lunar crust to a depth of 1,000 km is the lunar mantle, which occupies most of the moon's volume.

Underneath the mantle is the lunar core, which is about 1000 degrees warm and most likely molten. The diameter of the moon is about 3476 kilometers, which is 1 4 of the earth and 1 400 of the sun, and the distance from the moon to the earth is equivalent to 1 400 of the distance from the earth to the sun, so the moon is as big as the sun from the earth. The volume of the Moon is only 1 49 of the Earth, and the mass is about 735 billion tons, which is equivalent to about 1 80 of the Earth's mass, and the gravity of the Moon surface is about 1 6 of the Earth's gravity
