Mr. Reiter, the Apollo missions brought 382 kg of moon rock on the earth. Until today, there were more als100 space missions to our satellite. Actually, one would have to think: The moon is old hat.
Quite the opposite. It is amazing that we know today about our neighboring planet Mars a lot more than over the moon. The Mars is due to the possibility that there was once primitive life has existed or still exist could be strong in the focus of science. Living on the moon is rather unlikely. Nevertheless, the moon is a very interesting object in the sky.
The moon is to a certain extent, a history book for the development of our own planet and the solar system. According to the existing scientific understanding of the moon originated about 4.5 billion years ago by the impact of a Mars-sized asteroids in the proto-earth. In the moon of this original state is frozen. Because on the moon there is no plate tectonics. Many of the craters on the moon that can be seen even with the naked eye, are billions of years old. Therefore, you can learn through the study of the moon quite a bit about the history of our planet and the solar system.
What is the role the moon plays for the future of the space ?
If you would actually find the larger water resources, you could produce water on the moon via electrolysis columns, and oxygen for Breathing and hydrogen as a fuel. Since the moon is only one sixth the gravity of earth, you could advance from there, much easier in the Depths of space, such as to Mars. Our moon would be at the same time, a test field, in order to bring the required technologies to the required maturity.
The ESA Director Jan Wörner has brought the "Moon Village" into the conversation. It sounds as if you wanted to build on the moon a small settlement, just as one knows them from the earth.
Also with us, the concept of the "Moon Village has awakened" first of all, this Association. In fact, it is the ESA Director of something else: a new kind of cooperation between the space faring Nations.
"On Board the ISS, we can recycle today, over 70 percent of the water."
So, unlike, for example, in the case of the international space station ISS?
Yes. A program like the ISS took an enormous vote of the 15 Nations involved. There was a master plan. The concept of the "Moon Village" without a master plan. Rather, the Exploration of the moon should go, like a village.
Since someone built a farm. Then a couple of residential houses. Then a Church.
Exactly. This could be a model, if in the future more countries open up to the moon. The exact Plan is not available from the start. The project should develop. You will probably be come together in one place, such as at the South pole of the moon, because there is probably water that you need for the operation of the moon village urgently. The rest of the infrastructure will develop.
to realize Where you see the main challenges, for example, the idea of the "Moon Village"?
A major challenge of the protection from cosmic radiation. If you are staying on Board the ISS is shielded by the earth's magnetic field is still relatively well from the radiation. On the moon, this is no longer the case. In particular, you have to protect yourself storm there, from the dangerous sun.
You would have to dig into the moon.
You studied in fact, if you can the moon rocks, the Regolith, in a kind of 3-D printing layer and with a binder. So, you could protect against radiation and against micro-meteorites. Or you can use existing caves or lava channels.
moon settlers would also need drinking water.
As is the case with the energy supply, the intention is to promote the locally available resources and to lead in a cycle. Aboard the ISS, we can recycle today, over 70 percent of the water. The goal is to get to about 90 percent. Such technologies would you use on the moon and under the harder conditions of test.
And the breath of air?
On the ISS is filtered out carbon dioxide from the air. The filters are then regenerated in a vacuum. This means that You lose the carbon dioxide and the oxygen. But there are already so-called advanced closed loop system. Thus, at least a portion of the carbon dioxide is broken down through a chemical reaction in oxygen and carbon. The oxygen can remain in the circuit. So you have less of this resource to deliver. Appropriate technologies are, today, already tested on Board the ISS.
How to feed the inhabitants of the "Moon Village"?
On the ISS, one tries for example to grow crops such as lettuce and tomatoes in zero gravity. Also on earth there are appropriate Tests. The German centre for air and space travel, for example, grows vegetables in the Antarctic, in a completely closed Container with artificial lighting.
In what ways could benefit the normal citizen of the earth of this moon - and ultimately Mars missions?
In many regions of the earth, it is difficult to have a reasonable water supply. As technologies for water on the moon can be obtained could be very helpful. We develop these space technologies, and also with the thought in mind that they could have applications here on earth. Also, the space experiments on the cultivation of plants could be for the earth to be useful.
But down here it is much easier to grow plants than in space.
. But consider, for example, the influence of microgravity on mechanisms such as the Gravitrop to the photo-tropism: Why roots always downwards in the direction of the force of gravity, the plants, but the force of gravity, contrary to the light? If we understand this better, we could increase by a corresponding modification of crop plants root growth. Then crops would drive their roots as quickly as possible, and deep into the ground, and then they might also grow in dry regions on earth, in which it is difficult today to engage in farming.
What could go after, in their view, in 50 years, or the moon?
I don't know how far I want to sit this question out of the window. But I am firmly convinced that we will experience in the second half of the next decade, the return of humans to the moon. And I firmly believe that in the following years or decades, some of the manned moon stations. I also think that there will be observation platforms on the far side of the moon, where the telescopes are not disturbed by signals from earth. They could be used to detect potentially dangerous asteroids as early as possible.
The company Lunar Embassy sells land on the moon. It is time to secure the best building sites?
I've heard of it. But honestly, I think that is only for a Marketing gimmick. There are clear agreements on the level of the United Nations that you can buy on the moon and on other celestial bodies is no reason and ground. I have certainly saved me definitely not have such a plot of land on the moon.
