according to the US space report, when human beings finally build their homes on the moon, our lives will change dramatically. However, because we use good tools on the earth and may not be easy to use on the moon, scientists have been committed to the research and manufacture of machines that can be used on the moon. One example is the research and development of lunar construction equipment - lunar soil excavator

Chris zacini, head of the drilling system of honeybee robotics in New York City, USA, said: "bulldozers and excavators are quite bulky. We have invented a completely different way of excavation - using gas." The lunar soil excavation method invented by zacini is to inject gas into the soil, so high pressure is generated. Under the pressure, the gas is naturally forced to run upward. The strong impulse of the gas breaks the land and takes it away together, and then the soil is collected for use

lunar excavator

in July 2008, honeybee robotics received a contract from NASA to develop new lunar tools, which are suitable for astronauts to work and live on the moon, and will be an important part of NASA's "Constellation Program". With the knowledge he learned in the work of diamonds, coal and gold mines in South Africa and the knowledge of his doctor's degree in extraterrestrial mining research, zacini designed and invented a very creative lunar mining method, including a gas excavator

this so-called excavation mechanical device driven by compressed air includes 6. The dimensional tolerance and allowable deviation of plastic parts are composed of a gas pump, a thin hose and a thick hose and a storage container. When the gas overflows under pressure, the soil brought out is sent to the storage container through the thick hose. Zacini said, "it's like a vacuum cleaner, but it's in the opposite direction. Instead of sucking, the machine injects gas first and then obtains the required soil."

the weight of the gas excavator is much lighter than that of ordinary excavators, although the machine avoids many questions: where will the future lunar occupants get the gas needed to operate the machine? A better way is to exhale carbon dioxide gas every day. Another possibility is to burn the fuel left by the rocket thruster when landing on the moon and collect these gases

zacini said, "when a spacecraft is going to land on the moon, it will become a burden in case it will fly a distance longer than planned and prepare some additional fuel, and when you land successfully." Moreover, zacini believes that the gas produced by burning the remaining fuel of the rocket is a better way to power the gas excavator

reduce, reuse and recycle raw materials

once the machine collects the lunar soil or soil cover, it can use the collected lunar soil to accumulate and become an external building of the astronauts' habitat as a radiation shield, and it can also extract oxygen and other minerals from the lunar soil

in order to release the oxygen in the lunar soil, it must be heated at high temperature. The engineer suggested that the lunar soil be collected and passed through a heat exchanger. Or, if the gas source of the excavator is the remaining rocket fuel, the discharged gas is already hot gas. Then squeeze the hot gas into the soil to excavate the soil, and the soil will be heated up

because every time we bring some raw materials to the moon, we are adding extra burden to the spacecraft, so engineers must design a very frugal way to obtain the required raw materials, which can be obtained from the moon as far as possible, and the resources that can be recycled. Zacini: "on the moon, you will use recycling to do your daily life quite a lot."

for example, astronauts can carry only hydrogen instead of heavy water, and then add oxygen to create the required water resources, because oxygen is a heavy component in water, and oxygen can be extracted from the lunar soil, which can effectively reduce the weight of objects carried by spacecraft. Once water is produced in the lunar habitat, most of it can be recycled, without the need to create water resources from scratch

problems left to be solved

although engineers are working hard to prepare for our future life on the moon, some key problems have not yet found effective solutions

the problem of lunar radiation is something we have to consider. If we can't solve this problem well, radiation will become our fatal killer. Lunar residents will also fight against the ubiquitous lunar dust, because the lunar dust is almost omnipresent, which can cause wear and tear to machine joints and connectors, and prevent the door from being blocked. It will also pose a threat to the healthy people living here, causing respiratory diseases, and it is difficult to remove the lunar dust from the habitat. Other possible difficulties are astronauts' ability to adapt to the environment

zacini said, "you can see the earth on the international space station. If there is an emergency, you can return to the earth within an hour and a half and be admitted to the Earth hospital. Living on the moon, the earth is very far away from you, and you can feel the transcendent quiet life."

why did human beings migrate to the moon to live

In 1969, man realized his dream of landing on the moon for the first time. Nowadays, when many scientists are busy planning the future of human life on the moon, some people ask: should we try to return to this place now

zacini argued that the pursuit is worthwhile, not only in the pursuit itself, but also to give us more opportunities to invent and create new technologies, and prepare for mankind to finally explore Mars, and we hope to try to live in the world outside the earth

zacini said, "we need to explore. The spirit of exploration is inherent in human beings. It is only a matter of time before we establish human habitat on the moon. But I won't go now, or even choose to go home first, because this is joking about my life." When human beings can truly establish their homes on the moon, zacini said that he would gladly go to the moon to experience a detached and quiet life
