[00:00:01] This and more on DW Science Show, welcome to Tomorrow
[00:00:05] Today.
[00:04:18] of
[00:04:25] of
[00:09:12] on Moon: At first glance, the moon looks
[00:09:16] a bit like a desert, and for a long time scientists were sure there
[00:09:20] was no water on it. Now though, we know that
[00:09:23] there is, but where is it? And could we use
[00:09:26] it? Most the
[00:09:30] moon's water is found its south pole. Many
[00:09:34] craters there have no access to sunlight, and says
[00:09:37] NASA, are some the coldest parts the entire solar
[00:09:41] system. The... water here is permanent ice, some has been
[00:09:45] frozen for 3.5 billion years. temperatures are as low
[00:09:48] as min 240 degrees celsius. the
[00:09:52] LRO lunar orbitor revealed that there is ice lying just
[00:09:56] below the surface here, either as solid deposits or mixed with lunar
[00:10:00] dust, and there's a lot of it. estimates suggest
[00:10:03] hundreds of millions of metric
[00:10:05] tons. there's also water in
[00:10:09] moondust, what's known as lunar regulith.
[00:10:13] NASA's Lady mission showed that when rocks from space strike the
[00:10:17] moon's surface, they kick up not only
[00:10:21] dust, but also traces of water, even in areas subject to sunlight.
[00:10:26] and they are traces. The Sahara desert contains around
[00:10:30] 100 times more water than lunar
[00:10:32] dust.
[00:10:36] Can we access it? That's something for future lunar
[00:10:40] missions to find out. Either way, it won't be easy
[00:10:44] to extract. Temperatures are very low, the terrain is
[00:10:48] difficult, and it'll take a lot of
[00:10:50] tech. Water access will be
[00:10:54] crucial for. future lunar missions, it could be treated
[00:10:58] and turned into drinking water, or broken down
[00:11:02] into its components, hydrogen and oxygen, using
[00:11:05] electrolysis. These could be used for
[00:11:09] breathing or for rocket fuel.
[00:11:13] Until then, however, astronauts will still have to bring their water with
[00:11:16] them from
[00:11:17] earth.
[00:11:25] Space Exploration is all the rage among Genziers. That's
[00:11:29] because it boasts more opportunities than ever before.
[00:11:32] SpaceX and Blue Origin as well as numerous satellite startups are
[00:11:36] stirring things up. It's no longer just government
[00:11:40] agencies that get to explore up
[00:11:42] there. The space industry is
[00:11:45] expanding and attracting
[00:11:48] talent.
[00:11:55] With the help of this simulator, Alias Loisell is training his mining
[00:11:59] skills. He hopes to one day extract raw materials far away
[00:12:02] on the moon. Leissell studies space technologies at the
[00:12:06] Fryberg University of Mining and Technology in Eastern Germany and has
[00:12:10] big plans. It would be cool to have the
[00:12:13] opportunity to go to the moon, but on the other hand, it's also really cool just to be
[00:12:17] part of developing all of this and to find solutions essential for it
[00:12:21] to work, solutions without which it wouldn't be possible.
[00:12:26] extracting raw materials in space is laborious, dangerous
[00:12:30] work, the low gravity makes it difficult, as do the meter thick layers
[00:12:34] of lunar dust and the lethal radiation, a challenge for the
[00:12:38] scientists, we're looking for
[00:12:42] simple, hardwaring solutions that are robust, on the moon you can't
[00:12:45] easily repair equipment for example, so everything has to be lightweight,
[00:12:49] reliable and robust, like this rover
[00:12:53] for example developed by students here at the university, it moves
[00:12:57] across the rugged lunar surface, locating, extracting and
[00:13:00] transporting raw materials, soon it'll be possible to
[00:13:04] produce rovers like this on the moon
[00:13:06] itself.
[00:13:10] 3d printing is key, we're already able to print entire cars
[00:13:14] and so we want to use this technology to produce rovers directly on the moon
[00:13:17] using local materials, rather than having to transport
[00:13:21] every single piece of material we need to the moon.
[00:13:27] crude lunar landing is planned for 2028 as part
[00:13:31] the Artemis 4 mission. The plan is to then build a
[00:13:35] lunar station up there. It will be too expensive to restock
[00:13:39] this base with deliveries from earth, so astronauts will need to use
[00:13:42] resources very
[00:13:43] carefully. Luna
[00:13:47] astronauts will have to breathe the same air over and over, drink the
[00:13:51] same water, eat the same carrots, recycle like crazy.
[00:13:55] and by finding solutions we're developing technologies that are useful on
[00:13:59] earth too. data collected by the
[00:14:02] artemis 2 mission which launched in April 2026 will be
[00:14:06] used to prepare for the planned crude lunar landing in
[00:14:09] 2028.
[00:14:15] This is what dwellings on the moon could look
[00:14:17] like. Together with the
[00:14:21] European space agency, London-based design and architect. a firm
[00:14:25] has developed a master plan for modular lunar
[00:14:29] base in which human beings could work and live
[00:14:32] long-term. one big challenge is the lunar
[00:14:35] radiation, so thick walls could be
[00:14:37] essential. but how to build
[00:14:40] them? we're not going to bring our own concrete
[00:14:44] to build shell structures or caves to protect our
[00:14:48] astronauts. we better use local materials, so therefore we're going to
[00:14:52] use regulate, which is lunar dust. to create
[00:14:55] blocks that then what we called tetrapods that we can actually
[00:14:59] interconnect and create these structures, these shell structures,
[00:15:03] cave like structures under which our astronauts can live
[00:15:07] inside their inflatable habitats.
[00:15:11] it sounds great and the model looks impressive
[00:15:14] too, but what about putting it into
[00:15:16] practice?
[00:15:19] researcher is helping to develop the building
[00:15:23] material, although
[00:15:37] glass like sand. An alternative however is to cinter
[00:15:41] it. Cintering is similar to firing clay, it doesn't completely
[00:15:45] melt the regulis, but it does make the grains soft enough so that they can bond
[00:15:49] together. And afterwards you end up with a porous, solid
[00:15:52] composite material which could be used to make something like bricks for
[00:15:56] example, bricks you could then use to build walls
[00:15:58] with. We also use heat resistant plastics for
[00:16:02] 3D printing, and we mix in Regalith to boost the
[00:16:06] overall volume that... we can achieve a larger volume and so need to take less
[00:16:10] plastic with us for
[00:16:11] printing, with a
[00:16:14] special high temperature printer, it's even possible to process pure
[00:16:18] Regulith. It can be used its own or mixed with
[00:16:22] plastic. 3D printing has great potential for lunar
[00:16:25] construction work. NASA conducted tests with
[00:16:29] large format printers. One good option is to design
[00:16:32] lightweight inflatable structures and then clad them in
[00:16:36] regalice. 'and the
[00:16:40] plan would be to incorporate the assistance of small robots. What
[00:16:44] at first glance looks like vacuum cleaner, is actually mobile
[00:16:48] 3D printer. It applies Regulis layer by
[00:16:52] layer directly onto the lightweight base structure. All
[00:16:56] this is still just vision, but this, or something similar, could be what
[00:17:00] living on the moon looks like one day. Humanity is heading
[00:17:04] off to new realms and this exploratory urge drives'.
[00:17:07] find
[00:17:17] myself thinking, wow, i'm really working on these frontiers that we're
[00:17:21] currently pushing back, and working on lunar projects is
[00:17:24] incredibly inspiring, it fills me with enthusiasm,
[00:17:28] and i'm so grateful to be allowed to be so close to it all, it's totally
[00:17:32] crazy
[00:17:32] dran sein zu dürfen, das ist total
[00:17:34] verrückt. Imagine
[00:17:38] it's the year 3000. What would archaeologists dig up from our
[00:17:41] time? Very likely bits of plastic and fragments of
[00:17:45] synthetic clothing, which are already found in dense layers in the
[00:17:49] ground, thanks to our appetite for disposable
[00:17:52] fashion.
[00:17:56] T-shirts emblasoned with the latest designs, bang on
[00:17:59] trend, super short distressed look hot pants and
[00:18:03] must have. The latest fast fashion collection.
[00:18:08] will doubtless have a shorter product life cycle as
[00:18:11] ever.
[00:18:16] fon works to improve sustainability in fashion. she says one
[00:18:20] hurdle is the disposable
[00:18:21] mindset. what actually happens to the
[00:18:25] things we buy? if we take a look inside a typical closet, we
[00:18:29] see lot of tags still on
[00:18:30] the clothes,
[00:18:35] neue Sachen Kleiderschrank hängen. about 20% of all
[00:18:39] clothing produced and top
[00:18:41] of that, roughly 10 to 30% is never even sold in the first
[00:18:45] place, it's destroyed, burned, disposed of, that means more
[00:18:49] than half of what we produce goes straight into the trash,
[00:18:53] unused, that in itself is a massive
[00:18:56] problem, and fast
[00:18:59] fashion giants like primark seem almost harmless in
[00:19:03] comparison to online Chinese sellers like shien,
[00:19:07] more about ultra fast
[00:19:09] fashion,
[00:19:13] product life cycles are getting significantly shorter, things need to be replaced
[00:19:17] more quickly and consumption increases. ever more products are
[00:19:21] bought and as result the mountain of waste generated by this short-lived
[00:19:24] system continues to grow. at the federal
[00:19:28] environment agency in Desaw, eastern Germany, scientists like
[00:19:32] Karim Zaidi are working on ways to make textiles last
[00:19:35] longer by creating
[00:19:56] There is a whole range of product information currently being
[00:19:59] considered, one might be the durability the fibers
[00:20:03] used in the textiles. In other words, how long-lasting is the fiber.
[00:21:25] Here at Berlin's University of Applied Sciences, Elizabeth
[00:21:29] Epinger investigates the sustainability of fibers and
[00:21:32] textiles by putting them to the test in the
[00:21:35] laboratory. Most fast fashion
[00:21:38] items are not made to last, it takes just
[00:21:42] few test cycles to reveal weaknesses, although
[00:21:46] these can easily be missed in the store.
[00:22:50] how to recognize true
[00:22:52] quality?
[00:22:56] when we look at the textiles sector, it's clear that things are getting
[00:22:59] worse, and it's not just brands
[00:23:03] associated with ultra fast fashion that are doing it. we see
[00:23:07] the same trend in higher price segments as
[00:23:09] well. it's far from the
[00:23:13] case that higher prices mean better quality, and no
[00:23:17] matter how much it costs, isn't fassioned by it. nature,
[00:23:21] fleeting. Sustainable fashion like that sold
[00:23:25] in this Slow Fashion store in central Berlin remains a
[00:23:28] niche concept, and even if consumers are given more information about how a
[00:23:32] garment is made, will they actually use it, and how much does
[00:23:36] this information influence purchasing decisions
[00:23:38] anyway? Oliver McConnell,
[00:23:42] innovation strategist and fashion expert has his reservations about the
[00:23:46] digital product passport,
[00:24:04] You could for example say that if you buy fair fashion you get
[00:24:08] climate points which you could then redeem for cheaper
[00:24:11] electricity
[00:24:12] or to otherwise cut your household budget kind of
[00:24:16] payback program where you get immediate reward.
[00:24:50] digital product passport could be key to enabling buyers to make
[00:24:53] decisions based on facts and I'm certain that it will also be
[00:24:57] key to changing purchasing Kaufentsheidung
[00:25:01] sein wird. Following a preparatory and
[00:25:05] introductory phase beginning in 2027, the digital
[00:25:09] product passport for textiles in the EU is set to come into
[00:25:12] effect in
[00:25:13] 2028.
[00:25:21] Archaeological discoveries,
[00:25:25] water on the moon and building
[00:25:27] a lunar base. We'll be back soon with more stories from
[00:25:31] the world of science. See you then tomorrow today.
