00:04:25of
00:09:12on Moon: At first glance, the moon looks
00:09:16a bit like a desert, and for a long time scientists were sure there
00:09:20was no water on it. Now though, we know that
00:09:23there is, but where is it? And could we use
00:09:26it? Most the
00:09:30moon's water is found its south pole. Many
00:09:34craters there have no access to sunlight, and says
00:09:37NASA, are some the coldest parts the entire solar
00:09:41system. The... water here is permanent ice, some has been
00:09:45frozen for 3.5 billion years. temperatures are as low
00:09:48as min 240 degrees celsius. the
00:09:52LRO lunar orbitor revealed that there is ice lying just
00:09:56below the surface here, either as solid deposits or mixed with lunar
00:10:00dust, and there's a lot of it. estimates suggest
00:10:03hundreds of millions of metric
00:10:05tons. there's also water in
00:10:09moondust, what's known as lunar regulith.
00:10:13NASA's Lady mission showed that when rocks from space strike the
00:10:17moon's surface, they kick up not only
00:10:21dust, but also traces of water, even in areas subject to sunlight.
00:10:26and they are traces. The Sahara desert contains around
00:10:30100 times more water than lunar
00:10:32dust.
00:10:36Can we access it? That's something for future lunar
00:10:40missions to find out. Either way, it won't be easy
00:10:44to extract. Temperatures are very low, the terrain is
00:10:48difficult, and it'll take a lot of
00:10:50tech. Water access will be
00:10:54crucial for. future lunar missions, it could be treated
00:10:58and turned into drinking water, or broken down
00:11:02into its components, hydrogen and oxygen, using
00:11:05electrolysis. These could be used for
00:11:09breathing or for rocket fuel.
00:11:13Until then, however, astronauts will still have to bring their water with
00:11:16them from
00:11:17earth.
00:11:25Space Exploration is all the rage among Genziers. That's
00:11:29because it boasts more opportunities than ever before.
00:11:32SpaceX and Blue Origin as well as numerous satellite startups are
00:11:36stirring things up. It's no longer just government
00:11:40agencies that get to explore up
00:11:42there. The space industry is
00:11:45expanding and attracting
00:11:48talent.
00:11:55With the help of this simulator, Alias Loisell is training his mining
00:11:59skills. He hopes to one day extract raw materials far away
00:12:02on the moon. Leissell studies space technologies at the
00:12:06Fryberg University of Mining and Technology in Eastern Germany and has
00:12:10big plans. It would be cool to have the
00:12:13opportunity to go to the moon, but on the other hand, it's also really cool just to be
00:12:17part of developing all of this and to find solutions essential for it
00:12:21to work, solutions without which it wouldn't be possible.
00:12:26extracting raw materials in space is laborious, dangerous
00:12:30work, the low gravity makes it difficult, as do the meter thick layers
00:12:34of lunar dust and the lethal radiation, a challenge for the
00:12:38scientists, we're looking for
00:12:42simple, hardwaring solutions that are robust, on the moon you can't
00:12:45easily repair equipment for example, so everything has to be lightweight,
00:12:49reliable and robust, like this rover
00:12:53for example developed by students here at the university, it moves
00:12:57across the rugged lunar surface, locating, extracting and
00:13:00transporting raw materials, soon it'll be possible to
00:13:04produce rovers like this on the moon
00:13:06itself.
00:13:103d printing is key, we're already able to print entire cars
00:13:14and so we want to use this technology to produce rovers directly on the moon
00:13:17using local materials, rather than having to transport
00:13:21every single piece of material we need to the moon.
00:13:27crude lunar landing is planned for 2028 as part
00:13:31the Artemis 4 mission. The plan is to then build a
00:13:35lunar station up there. It will be too expensive to restock
00:13:39this base with deliveries from earth, so astronauts will need to use
00:13:42resources very
00:13:43carefully. Luna
00:13:47astronauts will have to breathe the same air over and over, drink the
00:13:51same water, eat the same carrots, recycle like crazy.
00:13:55and by finding solutions we're developing technologies that are useful on
00:13:59earth too. data collected by the
00:14:02artemis 2 mission which launched in April 2026 will be
00:14:06used to prepare for the planned crude lunar landing in
00:14:092028.
00:14:15This is what dwellings on the moon could look
00:14:17like. Together with the
00:14:21European space agency, London-based design and architect. a firm
00:14:25has developed a master plan for modular lunar
00:14:29base in which human beings could work and live
00:14:32long-term. one big challenge is the lunar
00:14:35radiation, so thick walls could be
00:14:37essential. but how to build
00:14:40them? we're not going to bring our own concrete
00:14:44to build shell structures or caves to protect our
00:14:48astronauts. we better use local materials, so therefore we're going to
00:14:52use regulate, which is lunar dust. to create
00:14:55blocks that then what we called tetrapods that we can actually
00:14:59interconnect and create these structures, these shell structures,
00:15:03cave like structures under which our astronauts can live
00:15:07inside their inflatable habitats.
00:15:11it sounds great and the model looks impressive
00:15:14too, but what about putting it into
00:15:16practice?
00:15:19researcher is helping to develop the building
00:15:23material, although
00:15:37glass like sand. An alternative however is to cinter
00:15:41it. Cintering is similar to firing clay, it doesn't completely
00:15:45melt the regulis, but it does make the grains soft enough so that they can bond
00:15:49together. And afterwards you end up with a porous, solid
00:15:52composite material which could be used to make something like bricks for
00:15:56example, bricks you could then use to build walls
00:15:58with. We also use heat resistant plastics for
00:16:023D printing, and we mix in Regalith to boost the
00:16:06overall volume that... we can achieve a larger volume and so need to take less
00:16:10plastic with us for
00:16:11printing, with a
00:16:14special high temperature printer, it's even possible to process pure
00:16:18Regulith. It can be used its own or mixed with
00:16:22plastic. 3D printing has great potential for lunar
00:16:25construction work. NASA conducted tests with
00:16:29large format printers. One good option is to design
00:16:32lightweight inflatable structures and then clad them in
00:16:36regalice. 'and the
00:16:40plan would be to incorporate the assistance of small robots. What
00:16:44at first glance looks like vacuum cleaner, is actually mobile
00:16:483D printer. It applies Regulis layer by
00:16:52layer directly onto the lightweight base structure. All
00:16:56this is still just vision, but this, or something similar, could be what
00:17:00living on the moon looks like one day. Humanity is heading
00:17:04off to new realms and this exploratory urge drives'.
00:17:07find
00:17:17myself thinking, wow, i'm really working on these frontiers that we're
00:17:21currently pushing back, and working on lunar projects is
00:17:24incredibly inspiring, it fills me with enthusiasm,
00:17:28and i'm so grateful to be allowed to be so close to it all, it's totally
00:17:32crazy
00:17:32dran sein zu dürfen, das ist total
00:17:34verrückt. Imagine
00:17:38it's the year 3000. What would archaeologists dig up from our
00:17:41time? Very likely bits of plastic and fragments of
00:17:45synthetic clothing, which are already found in dense layers in the
00:17:49ground, thanks to our appetite for disposable
00:17:52fashion.
00:17:56T-shirts emblasoned with the latest designs, bang on
00:17:59trend, super short distressed look hot pants and
00:18:03must have. The latest fast fashion collection.
00:18:08will doubtless have a shorter product life cycle as
00:18:11ever.
00:18:16fon works to improve sustainability in fashion. she says one
00:18:20hurdle is the disposable
00:18:21mindset. what actually happens to the
00:18:25things we buy? if we take a look inside a typical closet, we
00:18:29see lot of tags still on
00:18:30the clothes,
00:18:35neue Sachen Kleiderschrank hängen. about 20% of all
00:18:39clothing produced and top
00:18:41of that, roughly 10 to 30% is never even sold in the first
00:18:45place, it's destroyed, burned, disposed of, that means more
00:18:49than half of what we produce goes straight into the trash,
00:18:53unused, that in itself is a massive
00:18:56problem, and fast
00:18:59fashion giants like primark seem almost harmless in
00:19:03comparison to online Chinese sellers like shien,
00:19:07more about ultra fast
00:19:09fashion,
00:19:13product life cycles are getting significantly shorter, things need to be replaced
00:19:17more quickly and consumption increases. ever more products are
00:19:21bought and as result the mountain of waste generated by this short-lived
00:19:24system continues to grow. at the federal
00:19:28environment agency in Desaw, eastern Germany, scientists like
00:19:32Karim Zaidi are working on ways to make textiles last
00:19:35longer by creating
00:19:56There is a whole range of product information currently being
00:19:59considered, one might be the durability the fibers
00:20:03used in the textiles. In other words, how long-lasting is the fiber.
00:21:25Here at Berlin's University of Applied Sciences, Elizabeth
00:21:29Epinger investigates the sustainability of fibers and
00:21:32textiles by putting them to the test in the
00:21:35laboratory. Most fast fashion
00:21:38items are not made to last, it takes just
00:21:42few test cycles to reveal weaknesses, although
00:21:46these can easily be missed in the store.
00:22:50how to recognize true
00:22:52quality?
00:22:56when we look at the textiles sector, it's clear that things are getting
00:22:59worse, and it's not just brands
00:23:03associated with ultra fast fashion that are doing it. we see
00:23:07the same trend in higher price segments as
00:23:09well. it's far from the
00:23:13case that higher prices mean better quality, and no
00:23:17matter how much it costs, isn't fassioned by it. nature,
00:23:21fleeting. Sustainable fashion like that sold
00:23:25in this Slow Fashion store in central Berlin remains a
00:23:28niche concept, and even if consumers are given more information about how a
00:23:32garment is made, will they actually use it, and how much does
00:23:36this information influence purchasing decisions
00:23:38anyway? Oliver McConnell,
00:23:42innovation strategist and fashion expert has his reservations about the
00:23:46digital product passport,
00:24:04You could for example say that if you buy fair fashion you get
00:24:08climate points which you could then redeem for cheaper
00:24:11electricity
00:24:12or to otherwise cut your household budget kind of
00:24:16payback program where you get immediate reward.
00:24:50digital product passport could be key to enabling buyers to make
00:24:53decisions based on facts and I'm certain that it will also be
00:24:57key to changing purchasing Kaufentsheidung
00:25:01sein wird. Following a preparatory and
00:25:05introductory phase beginning in 2027, the digital
00:25:09product passport for textiles in the EU is set to come into
00:25:12effect in
00:25:132028.
00:25:21Archaeological discoveries,
00:25:25water on the moon and building
00:25:27a lunar base. We'll be back soon with more stories from
00:25:31the world of science. See you then tomorrow today.
00:25:35Take
