The memory has been earths Constant Companion for 4 and a half 1000000000 years. Now its finally back in the focus of science almost 50 years after man last set foot on the moon. Has more people at the percent of the total people on the surface that were not alive when then we had a last minute landing spins out all right and we havent done the next thing and some people say been there done that but what we havent done is to just touch the ground and if i can left right we havent really lived we havent explored surely if you want to commit the money to it like we did on apollo you could do it in probably 10 years. We did it in a years or 2 months. Now scientists are concentrating on ways to grow food produce energy and make a. Foules there. All over the world researchers are working on a return to the moon and the chance to be able to stay there longer. We have to use the moon to operationally understand. How to live in board on the planet and fully there are many ideas but actually putting them in the practice is the final step thats missing of a great the seem like humans return to the moment. When this will happen is not yet clear but science is making it possible to survive on the moon. On this wednesday in 1969 the world was holding its breath mankind was witnessing a historic mission. Onboard apollo 11 astronauts Neil ArmstrongMichael Collins and edwin buzz aldrin had a goal mankind had not yet reached to fly to the moon 5 days later in the Early Morning on july 21st Neil Armstrong uttered his unforgettable words. Or there are a lot. Of. Armstrong and aldrin spent a total of 2 and a half hours on the surface of the moon as they collected rock samples and raised the American Flag they were watched live by 600000000. 00 people. Only a few of them were aware that the successful moon landing was hanging by a thread in now says Mission Control center in houston cap com charlie duke had direct radio contact with Neil Armstrong. Now 82 years old he can still recall the dramatic moments. We get very very tight on fuel coal 60 seconds which many as 60 seconds to land i call 30 seconds the tension is rising in Mission Control you could hear a pin drop and we were holding our breath will we make it i called 30 seconds and then 13 psychos later he landed but it was very very tight. And very close to overboard. Yet the 1st Lunar Landing was a success. 3 years later charlie duke got his own entry in the annals of space travel. Don youre now were the 5th landing on the moon i can april 9th hes 72. 00 and i was the 10th man to step all of them and once we laid it i just erupted with enthusiasm i shouted into the end but we had our helmet solid and fully suited up an idea shouted in my helmet houston orion is finally here hes fantastic. Why are you only. On the surface of the moon charlie and his commander john young carried out experiments for example on Radiation Protection and. It was also it was beautiful one of most beautiful desert sun ever seen great a very rough topography up and down heli craters rocks hills everywhere and. Our objective was explore this valley so ahead i was excited was very happy to be there you were almost overcome with the thought of the moon in the morning. On april 24th 1972 they lifted off again. Only one further Apollo Mission followed half a year later. Im very disappointed that we havent had somebody go back. That that. There would be. They strain way. Optimistic about going back to the moon we need to build up of station although several over an article where we have a side station or an article thats a very hostile club in antarctica but we do it and i think we could do the same thing on the moon. And article is the earths most extreme continent nowhere else is it this cold with temperatures of minus 90 degrees celsius being measured here. 98 percent of the mainland is covered by ice thats 3 quarters of the earths freshwater reserves and the surface is one and a half times the size of europe and twice as large during the antarctic winter. Only a few animals can survive here and several types of penguins such as the emperor penguin have adapted to the hostile environment as have a few types of seals. And the conditions here in the eternal ice resemble the barrenness of the moon most closely. Which is why a team of researchers from bremen have made the long journey to the far south the 14 members of the german alice space center d. L. R. Will spend 2 months at the research station knowing my i 3. Since 2009 scientists have been conducting research here with different focuses such as need your own logy geology and atmospheric chemistry the architecture of the neumeyer 3 station has been adapted to the environmental conditions of the antarctic. Its built on stilts to keep it free of snow drifts up to 60 scientists stay here in the antarctic summer between november and february. Aerospace engineer powered sabah is the only member of his team who will also spend the winter here his task is to grow fresh vegetables as part of the even i as s. Project. The idea is to try out all going to seri technology and operational procedures here in the antarctic so that in future our greenhouse can also work in space. From growing between 15 and 20 different species of plant. We also have little strawberry plants. We can get them to flower so we can harvest strawberries in a few months. Until the mobile greenhouse reaches the antarctic by ship the team has to take good care of the delicate strawberry plants. Inside the station. And. Have tried to create the most ideal conditions. Strawberries are difficult to cultivate and thats why weve been providing our own little makeshift greenhouse. Of course its not optimal but we dont have much of an alternative if we want to keep the strawberry plants alive. It will take at least a few more days for the greenhouse to arrive any experiment here can really get going and soon on the moon. In order to live and work on the moon for a longer period of time. Research has to consider the conditions there and the differences to planet earth. d ringback 71 percent of the earth is covered in water it has an atmosphere layer of air and gases that surrounded and protected for example from meteorite impact and damage from various types of radiation it also ensures that temperature swings are moderate. 400000 kilometers away rather different. Water would have to be extracted from lunar sand by a vamp. Rating and condensing at the moment has no atmosphere to protect it from the impact of any flying objects. It is also exposed to dangerous cosmic radiation. Temperatures rise and fall so dramatically that humans could not easily survive. To make that possible in the future International Students of the European Space agency are conducting research with various experiments at the European Training Center for astronauts in cologne dr aden cowley is in charge of the spaceship project outside the center of a lunar station will be built for test and research purposes. So youre looking at is a is a foundation at the moment but next he wants to say going to rapidly change into a building and were going to a large 34 meter diameter dome were going to have 700 tons of regolith cement lego has to be able to tell you find on the lunar surface. A small settlement for now in cologne but in the not too distant future one on the moon 2. This is how the scientists imagine it will look. Inside theres an airlock and a Technical Area the main room is provided with daylight like in the i s s the oxygen supply is provided by chemically based air preparation. And there are good example of why we should go back to the moon would be to understand the radiation environment so if youre in a lower orbit at the moment you have the minute the sphere of earth protecting used to a certain degree but the minute you move beyond this you go to do nerve arm and you no longer have that protection and now youve got an entirely new radiation environment that have a different effect on humans. The lunar habitat will protect humans from this radiation with the strong outer layer this is the protective layer that we want to build so the idea is that we take material that is already on the moon and by applying the microwaves we could put it around their habitats and build like solid structure that will protect their habitat from the radiations and so on. Student oriented garcia from france is producing the heat required to sinter the powdery regulus baking it into a hard layer. At the moment however it looks more like pebbles than a flat surface. On the moon special robot vehicles would spread the lunar sand and sinter at the same time which would take about 3 months back then the apollo astronauts didnt have such a protective building. Well in a little 3 days it was a bad you could survive with just the regular. Protection that we had it took about 40 years for the scientists to figure out what the Apollo Missions really brought back the takes that long you have to develop the the the instruments to be sensitive enough to learn what these stones you know 300 kilos almost 400 kilos of stones that have been brought back from the moon what they really tell us. In the near. The trough apollo astronauts were not allowed to keep any souvenirs the original lunar regolith was simply too malleable. Just a stones throw away from the Research Center in cologne is the d. L. R. Institute for Solar Research should hear 2 scientists are researching regolith Radiation Protection professor and his team seek the most moon like conditions possible in their own making and often whats available in abundance on the moon is moon dust and plenty of radiation from the sun we would need several meters of moon rock or moon dust as protection from radiation from the sun and other cosmic sources. And thats one of the things that were researching this is einstein thing if you have a proof. The experiment is called regel light a word coined to combine regolith and light. Of course it doesnt use real lunar regolith but its simulant which has Similar Properties and will be centered to an entire brick using layered 3 d. Printing. What we want to show is that we can really produce a 3 d. Object whether x. Y. Or z. In a vacuum and this is the technology were developing here because. There is a vacuum on the surface of the moon to simulate this made under a factory and alexandre the mill this from france are creating the experiment in a vacuum chamber of thats. Our objective is to see what mechanical properties are if we send to something in a vacuum. Theres Something Better comes out come we construct a better building with it or not see. The strong xenon beams imitate the sun and can create a constant heat of around 1100 degrees celsius channeled into one ray they hit the 3 levels of moving moon sand below. It can take up to 5 hours under lunar conditions to bake a 3 dimensional object such as a brick. You want to see whether anything comes out on to the vacuum and then do the chemical analysis but the chamber is too small and very harsh it can rise as not so why the spheres when we have a big a chamber we can build a better cooling system or bigger components cooling system doll phone or. Scientists have to find the right parameters so that in future todays results will look like the brick sintered without a vacuum. As a last step they have to replace the artificial light with their solar furnace which consists of 159. 00 square mirrors and concentrates the light energy. It produces the necessary heat through constant sun radiation as exists on the moon. You have to make use of every resource you have and so i think 3 printing structures for habitate for habitations you know all these things that we can do now with existing infrastructure existing materials on the surface will be something want to take advantage of. Back to the antarctic the conditions can change unpredictably with the possibility of wind speeds of up to 60 knots thats hurricane force. The weather here is the deciding factor its exactly the right testing ground for the scientists with the perfect conditions for their research. Young doctors to stay up to lead and arctic is the most remote continent of the world its not easy to reach i mentioned the People Living here are dependent on the technology which keeps them alive just like in a Space Mission so was the best place to test the whole operation renos because im a twit disk of x. All the support. Almost everything is prepared for their project even i assess where theyre planning to grow vegetables and strawberries in a mobile greenhouse this platform has been standing here for a while 400 meters away from the German Research station neumeier 3 of the mobile greenhouse should have arrived here days ago but the cargo boat transporting it to the side is making slow headway through the thick pack ice. 14000 kilometers away in germany Moon Research is also. Being carried out various experiments for the project spaceship are being carried out at the european astronaut Training Center in cologne. Belgian students. Is working on a virtual environment where future visitors to the moon can train. Simulation like this we can train them into Virtual Reality as if they were already on the newer base and then have to. Interact with the Digital Rights and can completely be able to do the experiment before and instead of just being in the training room with their back and for. The 1st will moonscape is still in the Development Phase at some point however it could help with the preparation of future missions. Just. A few rooms away colleague me can easily get door is busy working with different devices his specialist area is 3 d. Printing. Is 3 d. Printer it works with polymer and the polymer. Behind basically it warms it up in here and then it melts i want to melt you can put it over surface it gets cold so its good to stick to the to the bed and you can bridge. And then layer by layer and make it through the object. Heating melting printing but for the next step we cant is particularly interested in the real usability of the plastic what were doing is here check if the materials work properly in the morning. After worth sickly we will check with our piece if we crush it and then we really extruded with this machine again and indeed again if it was the same as the. Object before. The coral containing the plastic would of course have to be much larger when it is transported to the moon look once its there the plastic could always be reused. In bordeaux france the 3 d. Printing process is being researched in a parabolic flight. Professor yes good stuff from c. N. N. Berlin the German FederalMaterials Testing institute has developed equipment with his team to enable parts such as tools to be made from metal powder in 0 gravity. You see the aim of the experiment is to try out a new process of sucking in powder and then trying to fix it and it is 0 gravity environment so in principle you can produce parts on demand the part which has been centered with a laser on to the plate should be able to be taken out and its ready for use. Of. The for each flight the scientists draw their conclusions from the previous flight making minor adjustments to try and improve the results of their experiment. So this is our 3rd flight day last time we switched the material and this time we have adjusted the parameters of the equipment to be able to apply the layer of powder id say we managed to get about 70 percent of the powder on to the layer and the rest by the way we need to improve that we cant have the powder flying around. I the Berlin Research team is just one of many in total the participants here in bardo fly for 4 hours on each of 3 days. There are 31 parabolas person light. The aircraft rises steeply upwards from its horizontal position. Reduces the thrust of the turbines and flies for around 22 seconds and 0 gravity. That is a particular challenge for the scientists as the Gravitational Force during a parabolic flight varies. Theyve adapted the structure of their experiment accordingly. The experimental apparatus looks like this. The metal powder is in a container at the beginning of a parabolic flight from there it spread in a layer over the base plate. So that it doesnt fly away in 0 gravity its sucked in by gas from below and kept on the base plate also during the 0 gravity. Then a laser mounts the relevant information onto the freshly applied powder it melts the loose metal powder into a compact structure this is done with every layer producing a 3 dimensional object in this case a spanner. A good step and his team can follow this process which is repeated several times via the installed webcams. The final results can be seen a little later in the laboratory. The metal powder has really been transformed into 2 small spanners. The experiment by goons does Research Group was a success. In the not too distant future all tools could be produced this way in space. In the antarctic the long wait is over the cargo ship has to from south africa has managed to break through the ice and the unloading can finally take place. After a 10 day delay the german scientists watch their mobile greenhouse being unloaded from the ship. Unloading on the ice has its hazards although the area around the ship is frozen the layer of ice is thinner than further inland. The whole process takes around 90 minutes in the end only as well and the squad sets off back to base. Its 23 kilometers away from the unloading point to new maya 3. Although there is no darkness in the antarctic summer as the sun never goes down they still have a regulated 8 hour working day this day ends with a long awaited arrival of the container at the station. The next day begins early and its time to build the greenhouse. The scientists have a whole container full of equipment which they have to unpack and inspect after such a long journ
