The space battleship landed in a crater in the South Pole, and from the warship's monitor, there was a gray atmosphere on Mars, and the sun hung in the sky, which was much smaller than the earth, and the sun's rays were not dazzling, it emitted a pale blue light.

?

Yes, Mars has a blue sun, which is caused by the refraction of light in its unique atmosphere.

?

In the crater where the battleship landed, white traces could be clearly seen in the shades, and even under the stones under the feet, these white crystals could be seen.

?

That's ice crystals, ice crystals that condense directly from water vapor.

?

The moon is a standard barren land, lonely and cold, with no atmosphere and no ocean. And Mars not only has an atmosphere, but also a huge ocean.

?

The Mars Expedition members stepped out of the battleship, and the human footprints set foot on Mars for the first time. They briefly enjoyed the unique scenery on Mars, and immediately went to various parts of Mars to complete their respective expedition tasks according to the tasks assigned in advance.

?

After determining the amount of water near the crater, the battleship gradually melted and disintegrated, and the construction of the first crater base on Mars began. One of the good things about Mars is that it has a ready-made atmosphere, and the base just needs to keep inhaling the atmosphere and then gradually adjust the gas composition.

?

There are more than 20 crater bases on the moon with successful experience, and the construction of the first crater base on Mars has not encountered any obstacles. When the dome of the crater base was closed, the expedition team members who were sent to various parts of Mars also got the exploration data of Mars.

?

Holding the freshly released Mars exploration data, Meng Yang studied it carefully. The remaining atmosphere of Mars is relatively thin, about 1% of the Earth's atmosphere, and the main body of the atmosphere is carbon dioxide, and the rest is nitrogen, oxygen and water vapor.

?

The distribution of water on Mars is relatively extensive, usually in solid form, and the Martian atmosphere has a basic water vapor cycle, which is mainly driven by solar energy.

?

The massive water bodies of Mars are mainly found at the poles, with ice sheets at the South Pole and ice at the North Pole, in addition to large glaciers beneath Mars. Judging from the exploration data, if all this ice were melted, it should be enough to submerge all the land of Mars.

?

Water is the source of carbon-based life, and a planet can become a living planet with water, and Mars' abundant water reserves can save a lot of effort when building planetary ecosystems.

?

With the water problem solved, oxygen and nitrogen are next, which can only be obtained from decomposing rocks.

?

After reading the exploration data, Meng Yang has a general spectrum, if you want to turn Mars into another earth, then a lot of work will be carried out from now on, after all, you need to recreate a Martian atmosphere, recreate a Martian ocean, such a huge workload can not be done in a day or two.

?

Meng Yang temporarily put down the study task at hand, and set aside a few days to specially design a unique functional life, which was like a giant banyan tree.

?

This Martian ficus tree has two energy modes, one that absorbs solar energy and one that uses nuclear fusion energy. When its seeds are dropped on the surface of Mars, it will take root and sprout on its own, absorbing moisture from the air, grabbing and decomposing the soil, and using the decomposed carbon and oxygen to synthesize organic matter for its own needs.

?

When it reaches a certain size, it grows into vesicles at the roots of trees, which contain an ant-like creature.

?

This ant is a standard working organism, it does not need to eat, its body tissues directly consume electricity, and its body has a biological battery responsible for storing electrical energy.

?

The work of ants is to keep chopping up the stones and eating them in the stomach, the rocks will be decomposed and reduced in the stomach, the metal elements are left for storage, and oxygen, nitrogen, and carbon dioxide are directly excreted from the body.

?

When the stored electricity is about to run out, the ants will automatically return to the Martian Banyan Tree to recharge, and at the same time send the extracted metal elements back to the Martian Banyan Tree.

?

The Martian banyan tree will keep growing, growing aerial roots like a banyan tree, and the branches that support itself continue to extend outward, as long as it keeps growing, a tree is a forest.

?

The larger the area covered by the Martian banyan tree, the more solar energy it absorbs, the more ants it can support, the more rocks it can decompose every day, and the more gas it releases every day.

?

After the design of the Martian banyan tree was completed, Meng Yang immediately sent the design draft to the Mars base, and the Mars base began to produce a large number of Martian banyan seeds, which were sent to the space shuttle and transported to various parts of Mars to be sown once they were produced.

?

It may take more than ten years for a banyan tree to grow on Earth, and this specially designed Martian banyan tree, it only takes a week to grow to the extent that it can grow aerial roots and give birth to ants, and it is almost visible to the naked eye.

?

The day after Meng Yang completed the design draft, the first batch of hundreds of thousands of seeds of Martian banyan trees had been sown all over Mars. In the time that followed, the Mars base worked at full capacity, devoting most of its resources to the production of Martian banyan seeds, which were scattered by the expedition team in batches.

?

After only a few days, the people on Earth were surprised to find that the color of Mars was slowly changing, the red color of Mars that had lasted for hundreds of millions of years was fading, and a layer of fine emerald green was gradually infecting this ancient red.

?

Astronomical telescopes were set up one by one, all pointing to Mars in the sky, and a large number of photos of Mars from various sources were exposed.

?

There are private shots of Mars under small astronomical telescopes, this kind of lens is not very high-resolution, and the intelligence can barely see the canyon peaks on Mars, see the meteorite impact craters dotted on Mars, and the tiny green dots on it.

?

There are also photos from the national large astronomical telescope, under this large lens, the changes on Mars are clearly visible, and there are very abrupt round green spots on it, the distribution of these green spots is very uniform, and the distance between each other seems to be measured, and the overall feeling is as if someone has put pixels on the empty red earth of Mars.

?

Later, I don't know which cow uploaded the photos of the Mars exploration satellite to the Internet, and under the lens of the exploration satellite, the changes that occurred on Mars are vivid.

?

First, the Space Battleship of the Moon Empire arrived on Mars, and then the Martian crater base was built, followed by the Martian base and began to sow seeds all over Mars.

?

In the days that followed, a peculiar species of trees sprung up in all corners of the Martian land, and the canopy of these trees spread over the red color of Mars with green. At the same time, living creatures began to appear on Mars, and a species of ants crawling around appeared in large numbers on Mars!

?

After the Moon, Mars is also green!
