The distance between the blue star and the moon is basically constant.

The distance between Mars and Blue Star is completely different, Mars is only 55 million kilometers away from Blue Star, and at its farthest point, it is 400 million kilometers.

This cycle is 26 months, which is 2 years and 2 months.

So unlike lunar exploration, there is a window period for fire exploration, that is, when Mars is closest to the blue star, of course, there will actually be an advance amount to let the probe fly for a while, waiting for the arrival of Mars......

Every time there is a Martian window, countries that have the ability to launch Mars probes will have some moves, otherwise, you will have to wait more than 2 years.

The most recent fire exploration window is at the beginning of 2029, when the Martian upheaval has not yet occurred, so the United States, Dongguo, Lucia, Nanyin Federation and other countries and the Xizhou Space Agency have not made any major moves, but only launched some ordinary lunar probes, only Hawk Island quietly launched a cargo spacecraft.

After a long trip, by September, these newly launched probes were in place, except for the detector of the South Cause Federation, which lost contact, the other probes were normal.

Hawke Island's cargo spacecraft also landed on Mars, carrying a 1.2-ton rover Duke VII and five 220-kilogram rover Duke VIII with its own propellers.

There are also 472 plant species or plant seeds, some bacteria and fungi, and some chemical fertilizers!

It landed on an island on the southern edge of the Martian Abyss Sea and captured a set of images of the smoke and rain that was sent back to the blue star.

The island was originally a plateau, but due to the continuous expansion of the deep sea, it became an island with an area of about 1,800 square kilometers.

This area will shrink, because the sea level of the Yuanhai Sea is still rising, and eventually its area will only be about 800 square kilometers, which is about the same as the Xingpo Kingdom, at least in the early stage, this area is completely sufficient.

This island was named New Hawk Island by the Hawk Island side.

They intend to use this island as the beginning of the Mars base, on the one hand, because it is located in the abyssal sea, the largest ocean of Mars in the future, and the climate is mild and humid, and the temperature difference will be relatively small, which is very suitable for the survival of blue star creatures.

On the other hand, the island is not far from the mainland, and it can be connected to the mainland by means of bridges in the future.

First of all, what they have to do is to see what kind of crops can be planted on Mars.

In fact, some scientists have long simulated planting in lunar soil, but it failed. The "lunar soil" doesn't seem to be suitable for growing crops – it's some extremely fine, sharp abrasive rocks that pierce the roots of crops.

Because the Moon has no atmosphere and no water currents, there is no possibility of weathering of lunar soil.

But Mars is different, Mars has an atmosphere, there used to be liquid water and even rivers, and on the soil that simulates Mars, crops have been successfully planted. The soils are made from volcanic rock rubble on the Blue Star – which separates the gravel particles into different sizes and mixes them in the same proportions as Martian soil (Martian soil data comes from data analysis by Mars rovers in various countries). They used the "Martian soil" to grow 10 crops, including soybeans, pears, cress, sesame and tomatoes.

Of course, this is just a simulated "Martian soil", and there is a difference between it and the real "Martian soil".

Moreover, the current atmosphere composition on Mars is completely different from that of blue stars.

The surface of Mars now has a pressure of 0.3 standard atmospheres, and it is slowly rising, with more than 98% of the atmosphere containing carbon dioxide, as well as small amounts of oxygen, nitrogen, and water vapor......

Under the operation of the Duke VII rover, the first piece of cultivated land on Mars appeared on New Hawk Island, with an area of only 0.8 acres, and on this 0.8 acres of cultivated land, the first batch of 48 blue star crops were planted, including corn, wheat, upland rice, barley, tomatoes, carrots, soybeans, mung beans, red beans, peanuts, etc......

In addition, Duke VII put 28 kinds of algae and other aquatic plants into a puddle of about 5 acres on the island.

"The Evil God"

A few days later, the corn sprouted and died.

The wheat sprouted, died,

Upland rice sprouted and died,

Barley did not sprout,

The tomatoes sprouted and died,

The beans did not sprout at all,

……

Anyway, either it didn't sprout, or after it sprouted, it died quickly......

Twenty-eight species of aquatic plants also seem to have been spared.

However, when Duke VII further examined the water samples from the puddle, a major discovery was made!

A significant amount of chlorella elliptical was detected in the water sample!

Further detection found that it was still alive! Even multiplied!

Chlorella is a spherical single-celled green algae of the phylum Chlorella, a spherical single-celled algae with a diameter of 3~8 microns, which is one of the earliest life on the blue star, appeared more than 2 billion years ago, and is an efficient photosynthetic plant, which grows and reproduces with photosynthetic autotrophic growth and is widely distributed.

It reproduces asexually, each cell can produce 2, 4, 8 or 16 quasi-spores, and when it matures, the mother cell ruptures, the spores escape, and when it grows up, it is a new individual. It is found all over the world, mostly in small shallow waters, but also in marine species.

At present, there are about 10 known species of chlorella on the Blue Star, and there are hundreds of varieties of chlorella. Chlorella is widely distributed in nature, with the largest species in waters. It is easy to cultivate, and can not only use light energy for autotrophic growth, but also use organic carbon sources for growth and reproduction under heterotrophic conditions.

In short, it reproduces extremely fast and has extremely tenacious vitality!

This result is not unexpected, the creatures of the blue star have always been the more complex creatures, the worse the adaptability, the simpler the creatures, the stronger the adaptability, and there are many miniature organisms that can survive in extreme environments such as high temperature and high pressure......

So it's no surprise that Chlorella elliptis became the only one of the first blue star creatures to survive and reproduce.

Next, Duke 7 conducted a second batch of experiments, and this time, three more algae, Chromococcus, Candida and Chlorella, successfully survived and multiplied in the water bodies of Mars!

At the same time, two kinds of lichen organisms have been successfully cultivated on Martian land.

The so-called lichen is also a lower plant, strictly speaking, it is actually a complex of algae and fungi symbiosis.

Due to the long-term close combination of bacteria and algae, both morphologically, structurally, physiologically and genetically form a single fixed organism, which is very cold-tolerant and drought-tolerant, and can grow on rocks, deserts or tree bark, in the alpine zone, permafrost zone and the north and south poles, other plants can not survive, while lichens can grow and reproduce alone, and form an endless vast lichen community.

Although no higher plants have been found to survive on Mars today, the discovery is gratifying enough.

There are so many low-level plants that can survive and reproduce on Mars, which shows that the environment of Mars is getting closer and closer to the blue star, and these low-level plants have a particularly strong reproductive ability, in fact, the modification of Mars may be better than that of higher plants.

They can also be made into food, but the cost and taste are a bit problematic, but in the early days of Martian colonization, it may not have been a problem. No matter how high the cost is, it is countless times cheaper than shipping it from Blue Star, and the taste can also be solved by more elaborate cooking.
