The energy on Mars was released wantonly, with storms and lightning flashing. This kind of picture lasted for more than half a year. It was only in September 2030 that Mars slowly calmed down, and a brand new Mars was displayed in front of the world.
Looking out from space, a blue planet is exposed in everyone's field of vision. Its northern hemisphere is basically surrounded by blue oceans, and the southern hemisphere is a huge continent.
The oceans in the northern hemisphere are almost the same as those on Earth. They are the same blue and charming.
The continent in the southern hemisphere has a yellowish color. Obviously, the heavy rain on Mars has washed away the gravel on the surface of Mars, and washed away the original red gravel, exposing the yellow earth beneath Mars.
The rivers above the continent are densely covered, and huge pits created by the impact of huge debris everywhere form lakes, just like pearls dotted on the continent, beautiful and charming.
In the sky of Mars, many large clouds can be seen. As the air flows, it forms different shapes. Obviously, Mars also has its own circulating air layer.
In the north and south poles of Mars, the cold climate began to freeze the oceans here, and slowly began to form an ice layer similar to the north pole of the earth. However, the southern hemisphere of Mars can be a huge continent. It's snowing, it's much heavier than snow
"What a charming planet"
Jiang Zhipeng, who has been resting for more than half a year, returned to Mars again. Looking at Mars from space, Jiang Zhipeng couldn't help but sigh
Liu Qingquan, who was also "beautiful and moving", also sent his emotions to Mars. I did not expect to transform Mars into this just by hitting Mars with Ceres. It can basically be said that Mars has become the second home of mankind.
"Is all data coming out?" Although it is shocking to the beauty of Mars now, you still have to look at the data of Mars to know how Mars has transformed, and what you need to do next.
"An autobiographical cycle of 24 hours and 4 minutes is 8 minutes longer than Earth"
"The revolution cycle is 601 days, which is 86 days shorter than the original orbit, and 236 days longer than the autobiography of the earth. The year of Mars will be long, and everyone should take longer holidays when the New Year."
Yang Tianya joked while transmitting the latest Mars data to the big screen.
"This can be there. After all, it is more than 600 days a year. It is reasonable to have more holidays. The earth is once a year for more than 300 days. We need more than 600 days of holidays to be longer."
Before I emigrated to Mars, I already spoke in Martian tone
"Haha" others naturally laughed happily after listening to this. The most important step in the transformation of Mars has been completed. It is much easier for everyone to transform Mars, and it is much better to see the current situation of Mars than expected.
"Mars gravity is 9.13, which is worse than Earth's 9.8, because the mass of Mars is still much lighter than that of the earth. In the later period, a large number of asteroids need to be dropped on Mars, and the gravity of Mars should be increased to at least 9.5 the above"
Mars's autobiography speeds up, its mass increases, and gravity naturally increases, but it ’s worse than Earth ’s.
"Mars 'northern hemisphere is basically covered by the ocean, leaving only a few islands. The southern hemisphere is a huge continent. The ratio of the area of ​​the ocean to the land is basically 1: 1, which means that the area of ​​Mars' continent is more than 70 million square meters Kilometers, accurate number 78.53 million square kilometers "
"How big is this area? It's almost equal to the total area of ​​Asia, Africa, and Europe on the three continents. Everyone let go of baby birth. Some places are."
"Haha ~" Everyone heard Yang Tianya's words and laughed.
"Now the atmosphere of Mars has a density of 80 of the Earth's atmosphere and a thickness of about 40 kilometers. It is also divided into several layers, such as the flow, the stratosphere, the upper atmosphere, and the ionosphere."
"However, the composition of the Martian atmosphere is far from that of the Earth. The content of carbon dioxide is as high as 90, and the content of nitrogen is more than 5. Only about 3 oxygen, which is the amount of oxygen that we put in a small amount. , Or there will be less, the remaining 2 or so rare gases, some of which are very harmful to the human body, and the air is not suitable for human survival. "
"But it is worth noting that Mars's atmosphere does not form something like the Earth's ozone layer that can block ultraviolet rays, so natural sunscreens are not available."
The oxygen content of the earth is as high as 20 or more. The oxygen content of Mars 3 is a disaster for people on earth. It only takes a few minutes to suffocate.
Not to mention that there is still a lot of toxic gases on Mars, and the ultraviolet rays will be more intense. These are too unfriendly to humans.
Well, the air still needs to be improved. The steps of ventilation should not be lazy.
"In terms of temperature, the temperature on the equator of Mars is only about 10 degrees, the temperature of the north and south poles is below 80 degrees, the maximum temperature during the day can reach 30 degrees, and the temperature at night will drop to more than 20 degrees below zero. The temperature difference is too large, mainly from Mars. The core is relatively small and does not generate enough heat itself, but compared to the past, the temperature of Mars is still acceptable. "
"And because there are more carbon dioxide and water vapor in Mars' atmosphere, these are greenhouse gases. I believe that the temperature of Mars will gradually increase, but the work of heating up is still necessary."
"The intensity of light on Mars is only about 0.9 times that of Earth. There is not enough light and the temperature cannot come up. You can increase the light by setting up large reflectors, and at the same time increase the temperature of Mars."
As Yang Tianya talked, the screens on the screen continued to switch with Yang Tianya's explanation. The format of pictures and text combined with the comparison with earth data makes it easy to understand the current situation of Mars, and Yang Tianya focused on Are some of the key data from Mars
These data are the key to whether Mars is suitable for human settlement and survival. As for other data, they are only listed without explaining them one by one.
It can be seen that although Mars now looks very charming and seems to be a livable planet, according to its own data, Mars is too unfriendly for human beings for the time being, and it is not suitable for human beings at all. But even so, everyone is full of hope for the future of Mars.
