Why can t the space station be placed directly on the moon, but let it float in space?

In fact, it is not unthought that the space station on the moon has been included in the space deployment in the last century, and it has been practiced, but later it turned out that this plan is a bit difficult. It is not difficult to get to the moon, but it is difficult to build a space station on the surface of the moon, and there are too many problems to overcome. There are three main reasons.

The first is the issue of distance, although the moon is the closest satellite to the earth. The distance to the universe may be negligible, but for the earthlings, the current technology to cross 380,000 kilometers is still an extremely huge project, and in order to complete the transportation of materials, countless amounts of materials will be consumed. You must know that at that time, intelligent technology was not developed, and robots had no way to participate in this mission, so the establishment of a space station was delayed.

The second thing to know is that the space station we see now was built in 10 years by many countries, and it was not completed overnight, and at that time it had consumed too much manpower and material resources to promote this plan, and if you want to rely on robots to re-establish the space station on the moon now, then the current effort will be in vain. Moreover, although the current space station is only 400 kilometers from the surface, it also consumes materials from many countries. <>

The third is the supply of resources, because if the space station is built to the moon, there will definitely be some permanent residents left. The living cost of these personnel is actually very large, and the construction period of several years may require a large amount of materials. Also, because it is too far away from the earth, some medical problems are difficult to carry out.

Of course, the moon is not a good space base, except for large and small craters, because there is no external atmosphere, so the temperature difference between day and night on the moon is extremely large, and the requirements for materials are relatively high. One of the things you have to worry about on the moon is being hit by a meteorite. Once such a thing happens, it means that all the previous efforts are in vain.

There are four reasons for this, the first is the distance, the moon is 380,000 kilometers away from the earth, and it is not easy to transport related materials. Not to mention that in the era when technology was not developed, robots could not participate in relevant tasks, and human beings were powerless to build a space station. The second is the problem of resource supply, even if people can use rockets to transport the people involved in the construction of the space station to the moon, it will take several years for them to build successfully, and a large amount of material supply will be required during this period, which is difficult to solve.

Finally, there are medical problems, and environmental problems, once the lunar staff face medical problems, it is difficult for them to operate on themselves, through simple drugs **, it is very likely that they will endure the pain when they return to the earth, already facing the danger of their lives, so the transportation of life support equipment has also become an important problem. In addition to large and small craters on the surface of the moon, there is a huge temperature difference between day and night, so the space station needs to be built with special materials, so it cannot be placed on the moon.

Because if you build a space station on the moon, more than ten years of hard work will be in vain, and the cost will be high.

Because space on the moon is the same as space on the moon, and the cost of putting it on the moon will be higher.

The space station is not stationary in space. There is no air resistance in space, and according to Newton's first law (in the absence of external imbalance forces, a stationary or moving object maintains its original state, (velocity)), the ISS only needs fuel to provide energy when it changes the direction or orbit of motion under the influence of the Earth's gravitational field, and does not need to use fuel to maintain its motion the rest of the time. Thus, when the ISS is orbited at a specific altitude, it only maintains its motion under the influence of the Earth's magnetic field.

Features of the space station:The space station is characterized by its relatively large size, complex structure, long flight time in orbit, multiple functions, and a wide range of space scientific research projects.

All space stations do not have the function of returning to the ground, but accept astronauts in space for experiments, which can make the manned spacecraft a tool for transporting only astronauts, thereby simplifying the structure of the space station, reducing the difficulty of its engineering design and reducing the cost of spaceflight.

Because there is no gravity on the moon, it can be more dangerous if it is built on the moon, and it is more difficult to build on the moon, so it floats in space.

It took almost a decade to get to its current size. It is a large one, more than 100 meters long, 51 meters wide, 6 meters in diameter and weighing 400 tons. Since the ISS is only a little over 400 kilometers from Earth, the cost of transportation is much lower.

When refueled, it can fly without fuel for more than 400 days**, and unlike the ground and the lunar surface, the space station can do experiments that can't or can't be done well in microgravity.

If the space station is built on the moon, it is vulnerable to attack. This attack is the effect of some meteorites. We can see many craters on the surface of the Moon, which were formed by meteorite impacts.

We cannot guarantee that the ISS will be hit by a meteorite on the Moon, but to avoid this risk, it is better not to build a space station in such a dangerous place.

Humanity's exploration of the moon is pretty much the same. There are no resources on the moon that humanity needs. Therefore, it makes no sense to build an ISS on the Moon.

If the ISS was built on the moon, humans would have to go to the moon before they could carry out the mission. The cost of intermediate losses is unnecessary. Therefore, human beings do not need to spend more money on the moon to build the moon on the earth, which is beneficial for human maintenance and space exploration, and can also save costs.

In fact, the living consumption of these people is very large. A construction period of several years may require a large amount of material. In addition, due to its distance from the earth, some medical problems are difficult to solve.

Of course, the moon is not a good space base. Except for large and small craters, there is no outer atmosphere, so the temperature difference between day and night on the moon is very large, and the requirements for materials are relatively high. There is one more thing to worry about on the moon, and that is the attack of meteorites.

Once something like this happens, it means that all previous efforts have been wasted.

Because it is very difficult to build on the moon, and the moon cannot build a space station at all, if a space station is built on the moon, the space station will float directly, so it is very inconvenient to do so, and I think it is much better to be physically better now than to float in space all the time.

Because the weather on the moon is very cold, and the body temperature of the human body is unbearable, it will not be built on the moon, because there is no way to better study the entity now, so it will be built in space.

Do you think the moon is very close, and there is not much difference between being built on the moon and being built on the earth.
