Just as Xiao Huaidan and Peng Youzhi, who were already about to be exhausted, continued to compete with the leaky lunar biological laboratory. Sitting in the cabin of the "Wu Gang 14" lunar landing spacecraft, Lu Mu Yan, Sanae Rika and Wang Qiu were busy playing with a bunch of oversized "remote control toys".

-- Although in order to meet the needs of this special mission, a lot of unnecessary experimental equipment has been urgently dismantled in the "Wu Gang-14" lunar landing spacecraft, leaving only the most basic life support system and communication system, but the space in the cabin is still very cramped. The spaceship, which was originally designed to accommodate two people, has basically reached its limit after barely sitting three people into it, and it is really impossible to continue to stuff people into it.

At this moment, Shikameyan, Sanae Rika and Wang Qiu were all holding a manipulator similar to a gamepad, staring intently at the display screen in front of them, manipulating all kinds of strangely shaped construction machinery in front of them.

In order not to waste this once-in-a-lifetime opportunity for lunar exploration, in just a few days, the space department launched its full efforts, and the State Council worked together to not only pack and take out all the space probes in the laboratory, but also searched all the dusty warehouses and museums, and took out some old works that were considered design failures and thus put them on the shelf, and even broke into the campuses of many science and engineering universities, and got a large number of various exploration robots, including wheeled, tracked, and quadruped walking. Six-legged walking ...... Even some engineering robots that were not designed for space programs at all have been carried to the moon by the space authorities without paying the expensive freight from Earth to the moon anyway. It's not a big deal to damage a few robots, but if any of them can be used, it's a big profit.

Even before China's first manned landing on the moon. The old-fashioned lunar exploration robots launched to the moon were all turned over from research institutes, museums, and warehouses, and a full fifteen units were collected in one go, and then teleported up with wormholes in a hurry, in order to collect the largest number of lunar rock and soil specimens in a short period of time before the wormhole disappeared, and then Wang Qiu, a porter, managed to teleport them back to the ground command center.

All of a sudden. More than three hundred autonomous robots were sent to the moon, and about two hundred of them could barely work in a vacuum. Then, they launched a frenzied operation on the surface of the moon called digging through the moon...... All right. This may indeed be an exaggeration, but it is an indisputable fact that the lunar wilderness around the "Wu Gang 14" lunar landing spacecraft has suddenly become a noisy and busy construction site.

Obviously. Just by virtue of such a few people on the moon. Most of them are still laymen, and it is obviously impossible to operate so many robots at the same time.

Fortunately, except for a small number of robots for other purposes that break down when they go to the moon, those that can continue to operate on the lunar surface at this time are basically space exploration robots designed and manufactured by the space department, which do not need to be operated at close range, but are completely remotely controlled by the ground command center -- any Mars rover or lunar probe in this world needs to send astronauts to follow it. Playing close-up remote control within line of sight?

Therefore, treat these detection robots that have the ability to work on their own. Wang Qiu only needs to get them on the surface of the moon and forget it, and the rest is the work of the Xichang ground command center -- as for the remote control of hundreds of robots to survey the moon at the same time, whether it exceeds the working capacity of the ground personnel, and whether it will cause the communication equipment of the ground command center to be overloaded or even damaged...... That's not something Wang Qiu needs to care about.

There is only one project that really needs real-time monitoring by Wang Qiu's on-site personnel, and that is the large-scale excavation and transfer of soil and rocks on the moon.

Therefore, Wang Qiu was manipulating a lunar excavator not far away at the moment, looking at this large jar with tracks, while shaking slightly, while digging out piles of lunar soil - because the moon is a vacuum environment, sound cannot be transmitted, so it cannot be heard when it is working......

――――――――――――――――――――――――

On early space probes, the way to collect alien soil (mainly Mars and the Moon) was similar to that of an excavator on the ground, and it was also a hydraulic lever arm and a bucket (the size of a toy excavator) that shoveled the soil from the alien surface into the experimental module on the rover.

However, in the daily cost of space exploration, each gram of cargo costs a staggering amount of money before it can be sent into space by a rocket. As a result, conventional bulldozers and excavators are too cumbersome for the probes that land on the Moon and Mars.

In order to collect lunar soil more efficiently, reduce the weight of excavators, and save the cost of launch vehicles, the US Aeronautics and Space Administration invented and perfected a completely different excavation method - the use of high-pressure gas scouring when formulating the "Return to the Moon Jihua" in the early 21st century.

This new method of excavating lunar soil creates a high-pressure environment by injecting carbon dioxide gas into the lunar soil – remember, the lunar surface is a vacuum with no atmosphere, so the air pressure is basically zero. In this way, the carbon dioxide gas injected under the soil will naturally try to get rid of the shackles of the soil under the action of pressure, and Xiangshang erupts. The strong momentum generated by the upward thrust of carbon dioxide gas will push the lunar soil open, and the lunar soil will be washed out with it, and it will automatically pour into the collector covered above.

Therefore, the moon excavator designed and built using this principle is very similar to a large cylindrical jar that moves, and the wheels or tracks are installed under the sides of the tank to move on the surface of the moon. In the center of the bottom of the jar, there are two tubes, one thick and one thin, and the thin tube is wrapped inside the thick tube. After the start of construction, the excavator injected carbon dioxide gas into the ground through a thin tube, and the sprayed lunar soil was transported into a storage container by the thick pipe. In general, the machine is like a vacuum cleaner, but it works on the opposite principle - instead of sucking in the dust directly, it injects gas and then sprays the soil directly into the collector.

The U.S. Aeronautics and Space Administration (NASA) has tested and found that this gas digging machine is indeed much lighter than conventional digging tools. But the question is, not to mention that it's very power-intensive, and on the moon without an atmosphere, where will the lunar probe get the carbon dioxide to run this thing?

As a result, the new lunar excavator was eventually shelved, and several subsequent lunar and Mars probes still used old-fashioned excavation tools.

But for Wang Qiu, who has wormholes and infinite teleportation capabilities, none of the above problems are a problem - the bottom of these rustic-looking lunar excavators are equipped with electric tracks, and once the stored carbon dioxide is exhausted, they will stop working, run the tracks, move to the wormhole, and then Wang Qiu will activate the ability to teleport it back to the ground. A brand new excavator was then sent from the ground to take the shift......

Relying on this method comparable to cheating, Xichang quickly collected hundreds of kilograms of lunar soil, and it is estimated that the final total amount of collection will be more than ten tons...... However, this thing can only collect fine particles of lunar soil, and cannot do anything about large lunar rocks.

As a result, the mission of collecting lunar rocks is currently being carried out by Kameko and Sanae Rika with mining equipment provided by Japan. And the equipment used by Miss Sanae Rika is also very Japanese, that is, the quintessence of Japanese anime, which is known as the quintessence of Japanese animation on the same level as magical girls-Mobile Suit Gundam!
