Out of the Eagle Falcon, ****, Du Yun and Robin. Coros had other expeditions, where they had to collect some rock and soil samples in a defined area, and at the same time, they had to use a small drilling machine to drill a well more than 100 meters deep on the lunar surface and drill core deep on the lunar surface for samples.

In fact, more than 440 kilograms of rock and soil samples have been brought back from the moon during previous human missions to the moon, which is undoubtedly of great help to mankind's understanding of the moon.

It's just that among these samples, they are basically samples from the surface of the moon, samples from deep rocks on the moon, and those previous astronauts did not bring back at all. After all, more than 40 years ago, space technology was far less developed than it is now, and the load of the lunar module was extremely limited.

But the moon landing mission organized by Tang Feng this time was different. First of all, the moon landing operation was announced to the public to be an exercise for the future manned Mars exploration program, so all the standards were implemented in accordance with the standards of the manned Mars exploration program.

Under this standard, the falcon's load will be greatly surplus, because the gravitational pull of the moon is much smaller than that of Mars, so even if the falcon's fuel is fully loaded, the load of the falcon will be much higher because of the reduced gravitational force.

It is for this reason that the Falcon carries some "luxuries" that were not even thought of in previous lunar landing operations, such as this small drilling vehicle weighing more than 200 kilograms, such as the two lunar rovers

These things are powerful assistants for the astronauts who landed on the moon, and with two lunar rovers, it is equivalent to installing two eyes for the falcon and the astronauts who landed on the moon to see far away, and with this small driller, the solid lunar rock formation will no longer be an obstacle. The astronauts were able to collect the vital rock samples of the deep moon with great difficulty.

They are all busy with work, and once out of the capsule, they can move on the surface of the moon for up to nine hours, beyond which it will not work, and the life support system should strike.

Don't look at the working time of the life-support system, which can last ten hours, but it takes fifteen minutes just to get out of the cabin. Then it takes the same amount of time to enter the capsule, and it also requires half an hour in the airtight compartment before taking off the spacesuit.

The Falcon is not the most advanced spaceship in science fiction movies, as long as people enter the airtight compartment through the airtight door, the air pressure in the airtight compartment will become the same as the air pressure inside the spacecraft almost instantly. That kind of situation can only appear in science fiction movies under the current technology.

In fact, it takes at least 20 minutes for the air pressure in the airtight to stabilize.

The other three astronauts were busy with work, and Tang Feng walked in the other direction. There is no task for Tang Feng in this moon landing operation, and his biggest task has already been completed, that is, to pay for it. So after the landing of the lunar surface. Tang Feng can arrange the actions after each exit at will.

Tang Feng walked out for about ten minutes, because of the terrain, Tang Feng couldn't see them anymore, so he calmly activated the star core, planning to use the star core to survey the moon. Although Tang Feng was not sure that the star core would perform various functions on the moon, since it cost so much money to come to the moon, Tang Feng's main purpose was to do it for the star core.

As a result, the truth is really similar to Tang Feng's guess. The star core, which can be said to be almost omnipotent on Earth, is simply unusable on the Moon.

Because the star core gave a statement that made Tang Feng helpless and had some thoughts. "Detected that the host is on another planet. However, because the current level of the star core is not enough, the star core cannot carry out various functions on this star, please upgrade the star core to the corresponding level as soon as possible, so that you can carry out all-round detection of this star! ”

The answer given by the star core really made Tang Feng a little imaginative. Obviously, when the level of the core is not enough, the core cannot be used on a planet other than Earth. And according to the information about the star core obtained by Tang Feng under the ground of Vincent Peak in Antarctica, the star core can be divided into four levels.

The first level is the most elementary star core that can't be upgraded, and the star core on your body is obviously not that kind of low-grade thing. On top of the most basic star cores, there are planetary star cores that can be upgraded to level five, stellar star cores that can be upgraded to level seven, and the most awesome star cores that can be upgraded to level nine.

The star core on Tang Feng's body is obviously a planetary-level star core that can be upgraded to level five at the lowest grade. However, the first owner of the Star Core, Andro. Fan. In Alexander's words, this star core is a perfect star core, and although Alexander can't tell if this star core can be upgraded to a stellar star core, he has great confidence in this star core.

Whether a planetary-level star core can be upgraded to a stellar-level star core is generally to upgrade the planetary-level star core to the top level, that is, to know after the fifth level, but the star core on his body said such a thing when he was at the fourth level, if you want to carefully consider the information given by the star core just now, then wouldn't it

The information given by the star core is unmistakably stated that the moon cannot be surveyed because the level of the star core is insufficient. It is also true that even if the planetary star core is upgraded to level 5, all functions can only be performed on the parent star, and cannot perform various functions on other celestial bodies in the same star system as the parent star. Only after the nucleus has been promoted to a stellar nucleus can objects in the same star system be detected.

But the star core just said that as long as the level is enough, then the moon can be detected. If this statement is based on the star core, doesn't it mean that the star core itself admits that once it is promoted to a stellar star core, then the moon can be tested?

In other words, this star core should have given an answer, that is, "Hurry up and upgrade me, I can upgrade to a stellar star core!" ”

This speculation greatly lifted Tang Feng's spirits. The star core will not give such information for no reason, there must be some internal truth that will make the star core give such information.

In fact, Tang Feng's guess was really right. What Tang Feng didn't know was that in the distant Star Alliance, there were many ways to identify star cores, and one of the very effective methods was to upgrade the star core to level 4 or 5, and then take the star core to other celestial bodies for testing. In this way, it is easy to discern whether the core has the potential to be upgraded.

This method is nothing at all for the Star Alliance, which has extremely developed space technology, and in the Star Alliance, perhaps the most ordinary ordinary people can freely shuttle through a star system and go to other planets in the same star system, which is too easy for the people of the Star Alliance.

But this method is difficult to implement on the earth, not to mention anything else, Tang Feng's way of hitting the wrong head by mistake cost Tang Feng almost 10 billion US dollars!

In other words, this test is worth $10 billion! (To be continued.) )
