And this diameter and depth is the ratio of the real impact.

It's just that when I changed to the surface of the moon, and when I looked at this crater, it was the exact opposite.

Compared with the Earth's craters whose depths are larger than their diameters, the craters here have an overall diameter that is larger than their depths.

And it's not even a single star.

According to normal logical data, its depth should be four to five times its diameter.

But the depth of the crater above it is only less than 2% of this diameter.

Using a simple numerical value, in this 100-meter-diameter crater, its depth is only two meters deep.

This is absolutely impossible in science, and it is precisely because of this that Lin Yi feels that something is not normal.

At this moment, Lin Yi almost understood the source of the feeling in his heart.

It is this kind of crater that covers an extremely wide area, and its depth is indeed very shallow.

And what is the reason for this scene?

For a while, such a question began to flash in Lin Yi's mind.

It's just at this moment, no one can answer him, and no one can tell him why this is the case.

"Is it because the density of the moon is different from that of the earth? Or is the surface of the moon relatively hard?"

It seemed like he was talking to himself, but when he said this, Lin Yi shook his head again, denying his idea.

It's not as I imagined. After all, when the base was built before, a deep foundation had been dug. Under such a foundation, there was no abnormality.

Especially when excavating, there is no difference from the earth.

This also indirectly shows that the density here is similar to that on Earth, but their mineral resources are somewhat different.

However, the density of the two planets is almost the same, but why does this phenomenon occur? Why are there two completely different situations?

According to normal principles, there is an atmosphere on the earth, and the friction and deceleration should be relatively shallower than that on the moon, right, but why is it the opposite?

And this must be done by himself, the unsolved mystery mentioned in the tenth system task.

After putting on the space suit again, he stepped out of the flying saucer again.

Standing at the bottom of a crater on the moon, Lin Yi slowly crouched down, his palms lightly floated on the surface of the moon, and he dug **** it.

The next moment, a handful of fine powder appeared in his hand.

This very easy digging progress made Lin Yi even more surprised.

There is no rock underneath at all, but why does this happen?

At this moment, Lin Yi is a bit stubborn. The more he can't figure it out, the more he wants to understand this matter.

"What's going on underneath? Why is this happening?

Why can't even a meteorite hit a deep crater?

Is it your own hidden secret?

Or is your core really hard? "

When thinking of the Earth's core, Lin Yi's eyes suddenly lit up, then quickly turned around and ran back to the flying saucer, took off his protective suit, went directly to the console, and said to the Bodo elf above:

"Does our flying saucer have a tunneling function on it?"

The excavation function, as the name suggests, is the ability to dig holes.

Lin Yi's thoughts at this moment are very simple, no matter what your reason is, can I find out if I dig it?

Is it because there is a layer of **** beneath you, and it was directly dug so deep for you that it was not explored.

What's more, at this moment, the depth of the crater where he is located is only about 100 meters.

So if you dig down another 100 meters, what will you find?

Not to mention whether there will be any unexpected results, just how many minerals can be found in the interior of the moon after this excavation.

This is also more conducive to the development of the moon in the future, which is also more conducive to the development of lunar minerals.

Do what you think of, it has always been Lin Yi's rule.

After he returned to the UFO, he immediately asked the elf, and the elf's answer did not disappoint him.

"Answer the owner's question, the flying saucer comes with its own excavation equipment, which can carry out shallow excavation, and the excavation depth is 700 meters."

At a depth of 700 meters, this is more than enough.

After hearing this answer, Lin Yi's face immediately showed excitement.

You must know that the depth of this crater is only 100 meters, let alone 700 meters of excavation, that is, the same depth, and you can find some reasons.

In this way, when he learned that his flying saucer had this function, Lin Yi immediately gave an order, instructing the elf to control the flying saucer and start digging down to the deepest part of the crater.

However, it has to be said that the performance of this flying saucer is too advanced.

Including the tunneling capacity of this banner, it is not comparable to ordinary machinery.

When Lin Yi gave the order to excavate the old ~www.mtlnovel.com~ UFO immediately changed its form.

This is not to say that the original round flying saucer suddenly became a rectangle or something.

Rather, it was said that the UFO was separated immediately after the forestry's order was issued.

Within the surrounding opaque metal casings, a small chasing and excavating equipment was immediately separated.

This thing looks like that kind of unicorn.

The front end of the body, like a shuttle, has a spiral sharp corner. The diameter of the sharp corner is not small, and the thickest position is about five meters.

And the length of this thing, according to Lin Yi's visual inspection, is at least about ten meters.

And behind this long sharp corner, there is a glass-shaped dome like a cockpit covering it.

Without the elf's explanation, Lin Yi could also guess that this should be the location of the manipulator.

At this moment, the circular cockpit of the "unicorn ship" is connected to the main cockpit where Lin Yi is, and there is a passage leading to it.

Seeing this, Lin Yi didn't think much about it, and just walked over.

When he came to the cockpit of the unicorn ship he named it, he found that the cockpit was much smaller than the main cab.

Although it has been expanded tenfold, at most three people can sit inside at this moment.

I don't know how it would be possible to seat another person here without ten times magnification.
