When can we live on the moon?

If you are an astronaut, there will be a moon base soon, and there will be people in it. It will come true in fifty years.

If ordinary people are still young up there, it is that the environment there is too bad.

The theme of the 1970s seems to be "Apollo Landing on the Moon". People who grew up in that era will be deeply impressed by "200 1: A Space Odyssey" released by 1968. The film also gave people an inspiration, but now more than 30 years later, there is still no significant progress in moving to the moon. Therefore, it can be concluded that there should be little hope of moving to the moon in the foreseeable historical span. But we still can't help thinking, if we can live, vacation or work on the moon, it should be a great thing, right?

We really want to move to the moon, but if we really want to turn it into a long-term living plan, some basic conditions are also essential. These conditions include:

1. Breathable air

2. Water

3. food

Step 4 seal the bunker

Step 5 be energetic

In fact, we can get as many resources as possible from the earth to the moon, but this idea is quite unrealistic, because the transportation cost required is simply astronomical. 1 pound (0.45 kg) will cost 50,000 dollars, while only 1 gallon of water weighs about 8 pounds. So, carrying 1 gallon (3.79 liters) of water will cost $400,000! So we can only transport things to the moon as little as possible, and at the same time, when we are on the moon, we should also produce and supply as much as possible.

Gases that humans can breathe, such as oxygen, are actually easy to find on the moon, because the soil on the moon itself contains oxygen, and we can also burn oxygen to get heat and electricity.

But the problem of water is very difficult. There is evidence that the Antarctic region of the moon may contain water resources in the form of buried ice. If so, these possible reservoirs can solve many problems, such as daily drinking and agricultural irrigation. At the same time, it can be converted into hydrogen and oxygen, which can be used as rocket fuel.

But if there is no water on the moon, we have to transport it from the earth. One method is to transport liquid hydrogen to the moon by spacecraft, and then make it react with oxygen in the lunar soil to produce water. Since water molecules contain 67% oxygen and 33% hydrogen, this is probably the simplest method. Moreover, this method also has the advantage that hydrogen and oxygen can generate electricity at the same time when they react in the fuel bunker.

At the same time, food is a problem. Each of us consumes 450 pounds of dehydrated food every year, so we need to carry at least a few tons of food in a migration. "We can grow food on the moon", indeed, this is a countermeasure that everyone on earth knows and will think of, but we think so because we live on the earth. Chemical fertilizers such as carbon and nitrogen are quite common in the earth's atmosphere, and there are also rich mineral deposits on the land. A ton of wheat is actually composed of a ton of carbon, nitrogen, oxygen, hydrogen, potassium, phosphorus and other substances, so in order to grow wheat, we must bring these chemicals that are not on the moon. Once the first crops are planted successfully, human migration will be stable, because these fertilizers can be recycled by nature. The process is: human beings grow food, then eat it, and then excrete it in the form of solid waste, waste liquid and carbon dioxide. And these wastes turn into fertilizer to nourish the next batch of plants, and so on. However, we must clearly see that if we want to start this natural biosphere cycle, we must first transport tons of food or chemicals to the moon.

Let's talk about shelters. The first shelter (house) is probably an inflatable house shipped from the earth. But many research reports also say that we can actually build houses with ceramic and metal structures on the moon.

The energy on the moon is still very challenging. We can use solar cells to get energy, but the illumination time of these cells is limited. So there is another method mentioned before, that is, hydrogen and oxygen act in the fuel bunker and generate electricity at the same time. In addition, the moon is rich in uranium, so nuclear energy can also serve as a lifesaver.

To sum up, can't you understand why no one has moved to the moon at this stage? Because it is too much trouble! But let's assume that if we want to send 100 people to the moon and make them self-sufficient, these are the things that everyone needs to carry:

1. Man's own weight, 200 pounds.

2. Dry food first (chemicals used to grow the first round of grain), 500 kg.

3. Initial shelter and survival device, 1000 lbs.

4. Production and living equipment, 1000 lbs.

Based on the weight of about 3,000 Jin per person, 100 people is 300,000 Jin. Moreover, we should also realize that the space shuttle weighs165,000 pounds without fuel, and all the production and living materials that 100 people depend on for the rest of their lives are also on these two space shuttles, so you should understand how conservative our estimate of the weight of 300,000 pounds is. It costs $50,000 per pound, and only 100 people will spend $654.38+0.5 billion on transportation. At the same time, it must also include the cost of design, research and development, materials, training, personnel management, and the actual funds for transporting production materials (this does not include the time and money needed to develop this near-earth orbit international space station). So it can be predicted that there are countless zeros at the end of this number. In addition, this is only a small immigration plan for 100 people, and we have to spend either trillions or hundreds of billions (attention! It's dollars! ), that if the whole human migration, what will be a situation!

Therefore, we can only say that you can think about flying to the moon to see Chang 'e. But don't forget, just think about it!
