There are many craters on the moon, some of them have a large diameter, there is a deep crater in the middle of these craters, and there are towering upright rocks around them, and the height of the craters is generally between 7~8 kilometers.

The size of the craters varies greatly, the small craters are less than 10 kilometers in diameter, and some are only the size of a football field; The large crater is more than 100 kilometers in diameter.

The largest crater is the Bailey crater near the south pole of the moon, with a diameter of 295 kilometers, which is slightly smaller than the province of Zhejiang in the east.

The total number of craters with diameters greater than 1,000 meters reached more than 3,300.

Most craters are named after famous astronomers or other scholars, such as Copernicus Crater, Archimedes Crater, Newton Crater, Yinbagu Crater, Cassini Crater, Shishen Crater, Zhangheng Crater, Zuchongzhi Crater, and Guo Shoujing Crater, etc.

However, most of the craters cannot form permanent shadow areas, because the moon also revolves around the sun like the blue star, and most of the inside of the moon crater can be irradiated by sunlight, because the moon has no atmospheric buffer to absorb heat, this direct radiation can form a high temperature of more than 100 degrees in any area......

Only the north and south poles of the moon, some small and relatively tall craters, and the angle of the sun's illumination are relatively sloping, can form permanent shadow areas.

One of them is the Colin crater, which has a diameter of only 21 kilometers and an internal crater area of about 320 square kilometers, which is equivalent to the size of a city in the eastern country, with an average altitude of more than 5,000 meters, steeper on the inner side and slightly more gentle on the outer side.

Originally, such a high crater was difficult to climb into the interior.

But now, on the Rainbow Valley side of the Hawk Island outpost, a magical mountain pass has been discovered.

This mountain pass, after further examination by Hawk Island, is speculated to have been formed hundreds of millions of years ago due to an asteroid impact.

The huge impact force of the asteroid caused the originally towering crater to directly crack a hole, and the large amount of lunar dust caused by the impact filled the bottom of the crack again, forming a perfect entrance......

What a miracle of nature, a miracle of nature!

Just like the Mediterranean Sea on the blue star, such a large ocean, but only a small opening in the Strait of Gibraltar is left to connect with the western ocean, which is really intentional by the Creator......

This pass was named the Water Ice Pass by the astronauts at the Hawk Island outpost.

They hope that this name will bring them good luck and allow them to find the most critical resource of the lunar base, water ice!

Inside the Moon Palace-1, they remotely controlled the "small tank" Queen 13 lunar rover, passed through the water ice barrier, and entered the interior of the permanent shadow area, exploring this area that humans or human probes have never entered......

The 1,200-kilogram nuclear battery carried by the Queen 13 allows it to obtain 2,000W of electricity and 15,000W of heat even when there is no sunlight......

The power of decay nuclear batteries is not high, but it can be stably supplied for 10-15 years, which is the advantage of nuclear batteries......

The gravitational pull of the moon is only one-sixth that of the blue star, it is subject to less friction, it consumes a little less energy to walk, and the power of 2000W not only allows it to move steadily, but also provides electrical energy for various exploration instruments......

Including lunar soil composition detector, multispectral camera, navigation terrain camera, lunar surface magnetic field detector, etc......

However, it has no analysis function itself, and artificial intelligence has not yet reached this level, it just collects a lot of data, takes a lot of photos, and then plays the lunar module and Blue Star Hawk Island, and lets professionals analyze this data.

After five days of exploration, it collected about 20 gigabytes of data and photos in the permanent shadow area and sent them to the lunar module and Blue Star Hawk Island.

And the results of the analysis of these data and photos made Roger André and others extremely excited again!

According to their analysis, in the permanent shadow zone of the Colin crater, there really is water ice!

And its reserves far exceed their previous estimates, conservatively estimated at at least 200 million tons!

After all, the total water reserves on the Blue Star are 13.6 billion tons, the water reserves of Lake Baikal alone are 23.6 trillion tons, and even the Dianchi Lake has 1.5 billion tons of water, which is an order of magnitude difference......

Calculated together, it is actually equivalent to the amount of water in 20 West Lakes......

If it is evenly spread inside the crater of 320 square kilometers, it is only less than 0.6 meters thick.

But, this is the moon! This is the moon that costs at least 10 million pounds to transport a ton of water from the Blue Star!

At this price, 200 million tonnes of water is equivalent to a value of 2,000 trillion pounds......

This major discovery made it possible to build a permanent lunar base and even a lunar space city!

Human immigration Blue Star may really be coming true!

Water is so important!

It is not only a necessary resource for Bluestar immigrants to eat, drink and even bathe, but also provides immigrants with hydrogen and oxygen as stable energy reserves, completely getting rid of unstable solar electricity.

Hydrogen can also be used as a reducing agent to smelt ilmenite widely present on the surface of the moon into titanium alloys, steel and other metals, becoming an important construction material for the lunar base!

In addition, in the permanent shadow area inside the Colin crater, Queen XIII also explored a large amount of dry ice!

According to preliminary estimates, the reserves are about 150 million tons!

Dry ice, also known as carbon dioxide, can further react with hydrogen produced by electrolysis of water, and under the action of lunar soil catalyst and sunlight, methane, methanol and other compounds can be generated through hydrogenation, methane is one of the main components of rocket fuel.

It does not require additional energy inputs, and uses only the resources and sunlight on the moon to obtain oxygen and fuel, which researchers call "extraterrestrial photosynthesis".

In the future, a moon base or space city could use this dry ice to produce steel, rocket fuel, and biomaterials, which are essential for robots or humans living on the moon!

Queen-13 even found a small amount of nitrogen ice in the permanent shadow zone! That is, nitrogen in a solid state!

They are located at depths 50 meters below the permanent shadow zone, which also proves that the Moon may have had an atmosphere similar to that of a blue star, but only because the gravitational pull was too small to retain the atmosphere, and only a small amount of nitrogen that turned into a solid state could remain in the permanent shadow zone.

According to preliminary estimates, the reserves are about 2 million tons!

Although the reserves are small, they are enough for early human lunar strongholds to mix with the oxygen decomposed from the water spots to create artificial air!

After all, it would cost tens of millions of pounds to launch a ton of air from a blue star to the moon......

These discoveries, Hawk Island has not been disclosed to the outside world, because these resources are non-renewable resources, and the number is not very large for the lunar base, it is an important strategic resource, if it is made public, I am afraid that the battle for supremacy on the moon will happen soon.

They quickly drew up a plan for a new lunar base based on these newly discovered resources.

In this new plan, based on these newly discovered resources, they will initially modify the environment of the lunar base and build an ecosystem that will make it suitable for the survival of blue star creatures!
