A thin atmosphere? Solar radiation? Can life on Mars be realized?

People on earth often talk about moving to Mars. But what if this has already happened and the first humans have settled on this red planet? What will life be like on Mars? Can we live on the ground or must we hide underground to avoid exposure to solar radiation? Can we land on Mars?

Have you ever thought about leaving this planet? So, consider Mars. The fourth planet from the sun. It can be 56 million kilometers (34.8 million miles) away from us, or it can be 40/kloc-0.0 million kilometers (250 million miles). Mars is about 53% the size of the earth, and it is the second smallest planet in our solar system (the smallest is Mercury).

Mars is named after the Roman god of war. Cairo, Egypt is actually named after Mars, because it is said that Mars was rising on the day when Cairo was built. The first spacecraft to fly to Mars was in 1965. It was called "Mariner 4".

Mars has two moons, Phobos and Demos. This is also the largest mountain range in the solar system and the location of the biggest sandstorm.

Mars and the earth are similar in land area. Mars has a unique red color because its surface is rich in iron minerals. The temperature on Mars can be as low as-153 degrees Celsius (-225 degrees Fahrenheit) or as high as 20 degrees Celsius (70 degrees Fahrenheit).

Over the years, many discoveries have shown that there may have been life at a certain node on Mars. In 20 14, NASA's Curiosity probe found a small amount of methane, which they thought meant that Mars once had some kind of life at a certain node.

Scientists have also found evidence of the existence of water and some other conditions that human beings must have to survive on this planet. However, these ancient oceans can provide about 1% of the water in the earth's oceans. Some other features of the earth have been found on Mars. Evidence shows that there are polar ice sheets on Mars.

So, what will happen if we escape to this red planet?

Even if you jump on the fastest spaceship from the earth, it will take 40 days to 9.5 months to arrive, depending on the address on the planet. After staying in space for so long, you finally see the dry and lifeless Mars on the horizon. But can you survive there? What exactly does it take to survive on Mars?

First, you must find out how to make oxygen to breathe. The atmosphere of Mars is very thin, 95% is carbon dioxide. You can't just carry the oxygen you need to survive, but you can use a machine to extract oxygen from carbon dioxide like Moses of NASA.

This will not only provide you and another Martian colonist with breathable air, but also provide you with liquid oxygen propellant. If you want to return to Earth, this is what you need to get the rocket off Mars. There is no land for growing food on Mars. Instead, you can use hydroponics-growing crops in minerals and nutrient solutions without soil.

Of course, without the water flowing on the surface of the planet, your colony can only grow 20% of the food you need. You need to send the rest from earth. But don't expect fresh meat, all food will dry out.

Where do we live?

Like other immigrants, you may live in an inflatable and pressurized building. But it is more likely to go underground. Because Mars has no global geomagnetic field and the atmosphere is so thin, the radiation level in the orbit above Mars is 2.5 times higher than that of the International Space Station. This kind of solar radiation is unbearable for human beings.

Forget tanning, the sun is only half as big as what you see on earth. If you want to go out and come back alive, you need a spacesuit to make up for the almost nonexistent atmospheric pressure and block radiation.

Your clothes can also keep warm, which is very important because the temperature on Mars is very low. Compared with the average Martian winter, the coldest winter on earth is also a paradise. The temperature can be as low as MINUS 55 degrees Celsius (-67 degrees Fahrenheit). The poles are colder, and the temperature can be reduced to-153 c (243 f).

A day on Mars is 40 minutes longer than a day on Earth. But a year on Mars is about twice as long. If you live in the northern hemisphere, you will enjoy seven months of spring and six months of summer. Then there will be five months of autumn and four months of winter.

The temperature there is not only low, but also may change dramatically within a week. These changes often lead to strong sandstorms. They won't hurt you, but they will block all your electronic devices. It's almost impossible to make a video call with your family, because no matter what you say, it will take 15 minutes to reach the earth.

Also remember, the gravity on Mars is about one third of that on Earth. You need to learn to walk again. Still want to move to the red planet? Then your best choice is to wait until the first colonists arrive there and globalize the planet-make it like the planet they came from.

Ice, ice and babies:

They introduced ammonia ice from the atmosphere of other planets to heat Mars slightly. Heat will turn the dry ice in the North Pole of Mars into gas, giving the planet an atmosphere. Although we still can't breathe directly, it can at least generate enough atmospheric pressure for you to finally take off your spacesuit.

Then they will extract water from a large amount of water ice stored under the surface of Mars. Water vapor will make the atmosphere thicker and thicker, and eventually you can see rain and snow on Mars.

Then maybe in a thousand years, there will be enough oxygen for human beings to breathe. The reconstruction of the planet will also be completed.

Will living on Mars be something you want to try? Or would you rather keep everything on our planet?
