A few questions about Mars, about Mars

The surface soil of Mars is rich in ferric tetroxide, so it is red in color and visible to the naked eye.

The closest planets to the earth are Mars and Venus, but Venus has great air pressure, the air contains a lot of dioxide ponds, sulfur dioxide, and the temperature is very high, which is not suitable for life to survive, and the environmental indicators of Mars are more in line with the requirements of human habitation, so although there is no difference between landing on Mars and landing on Venus in terms of technical level, but in the long run, landing on a planet is undoubtedly to establish a permanent base, so Mars is more meaningful.

If you were going to spend three years going to one place, and you only had one travel companion on the way and the space was so small, would you be crazy? Astronauts are human too!

1st floor, you are wrong in this sentence "So landing on Mars is no different from landing on Venus at the technical level", the surface temperature of Venus is as high as 460, which is enough to bake people into charcoal; The surface atmosphere of Venus is 100 times that of the Earth, enough to squash a person; The carbon dioxide on Venus is 10,000 times that of Earth, enough to suffocate a person; and a dense sulfuric acid fog tens of kilometers thick that has a strong corrosive effect over it If humans can land on Venus, I think they should also be able to land on the sun

Mars doesn't suit you, come be realistic.

Think Mars has what it takes to ask for some of the questions you mentioned above.

In addition, the temperature of Mars is about the same as that of our north and south poles.

So it's still suitable for us to go.

Or is Mars the closest to us. There are a lot of uncertain dangers in space travel, and there are also a lot of harmful rays. There is also flight fuel and food that are not easy to solve, so the sooner you need it, the better!

And over time, the garbage we produce will also increase, which is difficult to dispose of. There are many more reasons to think about it for yourself.

The telescope is certainly clearer than with the naked eye.

1. Mars is red because of iron oxide.

The most surprising fact about Mars is its distinctive red color. The reason for its red color is that its surface is filled with a large amount of iron oxide, so the ores and mountains on Mars are oxidizing all the time.

2. Smaller than the Earth.

Despite the fact that it is the second smallest planet in the solar system, with a diameter of "only" 6,800 kilometers, so the Earth is almost twice the size of it, the Red Planet enjoys several planetary records due to its incredible geomorphological conditions.

3. Mount Olympus, the highest peak in the solar system.

One of the records is that Mars has the highest mountain in the solar system. The Mount Olympus volcano on Mars is about 23 kilometers high, almost three times the size of Mount Everest, and the diameter of the base of the peak reaches 600 kilometers.

4. The deepest canyon.

Another of its records is the possession of the deepest canyon in the solar system, the Valley of the Sailors near its equator. The canyon covers an area of 4,000 kilometers, and even the width of some points reaches 700 kilometers and the depth reaches 7 kilometers.

5. There are 687 days in a year.

Since the orbital radius of Mars is greater than that of the Earth, it takes longer for Mars to make a circle around the Sun, and it takes a total of 687 Earth days for Mars to orbit the Sun, which is the duration of a Martian year.

Mars is called Mars because of the use of astronomical telescopes.

When observing Mars, it was found that it was red as a whole, like a burning fireball, but the reason why Mars is red in appearance is because its surface is covered with hematite.

It is not as hot as one might think, but extremely cold, with an average temperature of around -23 on Mars all year round.

Mars has an axis of rotation tilt of degrees, which is similar to that of Earth, so it also has four seasons, but the seasons are about twice as long. Since the eccentricity of Mars orbit is approximate, the length of each season is inconsistent, and because of aphelion.

Close to the Northern Hemisphere.

On the summer solstice, spring and summer in the Northern Hemisphere are about 40 days longer than autumn and winter.

Reason for detection:

1. Mars is one of the closest planets that humans can explore on Earth.

2. About 4 billion years ago, Mars had a similar climate to Earth, with rivers, lakes and possibly oceans, but unknown reasons made Mars look like this. Exploring the causes of climate change on Mars is of great significance for the preservation of Earth's climatic conditions.

3. Mars has a huge ozone hole, the sun's ultraviolet rays.

Shine on Mars without obstruction. Probably that's why Corsair 1 and Corsair 2 failed to find organic molecules. Mars research helps to understand the Earth's ozone layer.

Once it disappears, the extreme consequences for the planet.

4. Searching for fossils of life that has existed in history on Mars is one of the most exciting purposes of planetary exploration, and if found, it means that life can rise on planets in the universe as long as conditions permit.

4.6 billion years ago, the solar system was born as a result of a supernova explosion.

Huge vibrational waves compress the gas residue into tiny clumps of matter. These clumps of material gradually join together to form the asteroids, comets, moons, and planets of the solar system. Computer models suggest that Earth's metal cores began to form between 20 million and 30 million years after the supernova explosion, but earlier geographical evidence suggests that this number was about 50 million years after the supernova explosion.

Mars is the fourth of the nine planets, half the size of Earth, and it is a planet, the last of the Earth-like planets in the solar system.

In ancient Europe, Mars was called "Mars", and the "god of war" in ancient Roman mythology was also known as the "Red Planet". In ancient Chinese, it was called Yingfu because it was like fire, and its position and brightness changed from time to time.

The Martian atmosphere is dominated by carbon dioxide (, which is thin and cold, full of impact craters, canyons, sand dunes and gravel, with no stable liquid water. The Southern Hemisphere is an old, crater-filled highland, while the Northern Hemisphere is a younger lowland plain. The largest volcano on Mars, Mount Olympus, and the largest canyon, Mariner Canyon.

Mars has two natural satellites: Phobos and Deimos, which are irregularly shaped and may have been captured asteroids. Based on observational evidence, groundwater-like outpouring was observed on Mars, with partial retreat of the Antarctic ice cap, and radar data showing the presence of large amounts of water ice beneath the poles and mid-latitude ground burners.

Formation of Mars:4.6 billion years ago, the solar system was born as a result of a supernova explosion, and huge vibrational waves compressed the remnants of gas into tiny matter. These materials are gradually joined together from the blocks to form the asteroids, comets, moons, and planets of the solar system.

Computer models suggest that Earth's metal cores began to form between 20 million and 30 million years after the supernova explosion, but based on geographical evidence, the number was proposed to be about 50 million years after the supernova explosion.

Mars is the third smallest planet in the solar system, with a diameter of about one-half of the Earth, a volume of about one-tenth of the Earth, and a surface gravity about one-third of that of the Earth. The atmosphere of Mars is thinner than that of Earth, only one hundredth of the nightshade in the Earth's atmosphere, and the main component is carbon dioxide. There are also a small amount of clouds and morning fog.

Because the atmosphere is so thin, there is no chamber effect on Mars. Near the equator of Mars, the temperature can reach 27C during the day and drop to minus 111C at night.

Mars is called Mars because when you observe Mars with an astronomical telescope, you find that it is red as a whole, like a burning fireball, but the reason why Mars is red in appearance is because its surface is covered with hematite, which is not as hot as people think, but extremely cold, and the average temperature of Mars is about -23 all year round.

The reason why Mars is called Mars.

Mars is called Mars because when you observe Mars with an astronomical telescope, you find that it is red as a whole, like a large burning fireball, hence the name. The reason for the red color of Mars is that the surface is covered with hematite, which gives the impression that the Loose Silver People are very hot and dangerous.

Many people think that when they hear the name Mars, they subconsciously feel that it is very hot, but in fact, Mars is not only not hot, but even very cold, according to scientific exploration, the average temperature on Mars is about minus 23 degrees Celsius.

About 4,000 years ago, the ancient Egyptians called Mars the "Red Star", while the ancient Babylonians and Greeks shunned Mars as the "Star of Death" and watched over the survival of people on Earth.

Mars Introduced

Mars is the fourth planet in the solar system from the middle of the mountain to the outside, about 5,500 kilometers away from the earth, it belongs to the desert planet, the surface is covered by sand dunes and gravel, there is no stable water source, the atmosphere dominated by carbon dioxide is very thin and cold, and dust storms occur all year round, but despite this, Mars is still considered to be the most likely planet in the solar system to have life.
