This week, were heading into space to find out how well live, work and eat on the moon. We have space homes and a spacewoman. All of a sudden, it clicked in my head. Wow, the International Space station is a submarine in space. Moon bots and moon dust. The surface is fine and powdery. I can pick it up loosely with my toe. You know, i think ive seen that chap somewhere before. Jfk we choose to go to the moon in this decade and do the other things, i not because they are easy, but because they are hard. Neil armstrong its One Small Step for man. One giant leap for mankind. 52 years ago, we laid our last footprint on the moon. As the crew of apollo 17 left the surface, they didnt know that gene cernan would be the last person to walk on Another World for quite a while. Were on our way, houston. But now, in this decade, finally. Were going back. And liftoff of artemis 1. Nasas Artemis Programme will, in the next year or two, return us to our neighbour. Part of its mission to land the first woman and the first person of colour on the moon. Another part to use what we learn here to send the first astronauts to mars. This is where it all began, floridas Kennedy Space center, named after the president who made the original pledge to go to the moon. And now this place is at the centre of even grander plans, because this time were notjust visiting the moon we want to stay. This is gateway, humanitys first Space Station that will orbit Another World. It will go round the moon every seven days. And, like the International Space station above earth, astronauts will call this place home. Although, where the iss can accommodate up to 12 astronauts and is comparable to a five or six bedroom house, gateway will be. More cosy. Gateway is a studio apartment. Its. Were going to have room for our four astronauts, multiple docking ports, so we can bring our orion crew transportation ship, we can bring logistics, and we can dock a lander. These four explorers wont all be cooped up on board for the whole time, though. Two will actually be spending a week or two on location down on the lunar surface. Its a chance to further study the landscape and hopefully find a location for our next giant leap a Permanent Moon base. Gateway will be there before we put a habitat on the surface. Gateway allows us to access any point on the lunar surface. When we went with apollo, we had to pick that spot on the moon and go to it. Gateway will give us the opportunity to go down at different locations. The first section of gateway could be launched as early as 2025, with new modules then being added from 2027. A lunar base is admittedly further out and it comes with risk, but also reward. So how do we make that a reality . To find out, its time for me to take One Small Step of my own. Oh, wow. I can instantly see the dust kind of kicking up. Yeah. Its really fine, isnt it . It leaves the footprints like youd expect. Oh, my gosh. Thats brilliant. And this is how moon dust behaves, itjust puffs up like that . It does, yeah. Its so fine. Welcome to swamp works. The dusty, dirty lab where they work with simulated moon dust. Now, the loose soil that covers the lunar surface is called regolith. Its extremely fine, very sharp on a microscopic scale, and it gets everywhere. So when we landed with apollo 11, we didnt know what the surface of the moon exactly was going to be like. Youll notice from some of the footage, the landing pads are quite huge on the landing legs and the ladder� s far away from the surface. There was a lot of concern of, how much will this lander sink into the surface . How fluffy is this regolith . The surface is fine and powdery. I can. | can pick it up loosely with my toe. In fact, its because the eagle lander didnt sink in as much as expected that Neil Armstrong had to take such a giant leap from the bottom rung of the ladder. Today, swamp works is developing robots that can cope with and take advantage of lunar soil. And it will be very useful. See, moon dust is made of materials like Silicon Dioxide and calcium oxide, which all contain a lot of oxygen. If we could mine the regolith and use chemical processes to extract the oxygen, we could make our own breathable air and our own rocket fuel. The way Space Flight Exploration has been working right now is imagine youre going on a holiday with yourfamily, youre going on a long road trip, thousands of miles, right . Right now, we are bringing a trailer behind us with all the gas, you know, that we need with us, all the fuel, everything that we need comes with us. So we want to change that paradigm. We want to. And one of the biggest things that makes the biggest impact is the fuel, right . If we can source some of that from the moon and eventually from mars, that will allow us to bring more and to go more often. Making our own fuel makes regular trips to and from the gateway Space Station much more viable. Now, Mining Moon Dust is called isru. And, because they love an acronym round these parts, the robot to do this will be called the isru pilot excavator, ipex. We had to really reinvent how you do excavation for doing mining on the moon, and eventually mars. The challenge is the technology we have for mining here on earth relies on a lot of mass and a lot of weight, right . The more steel you put on an excavator, the heavier it becomes and the better it digs. We cant launch something as heavy as we want on a rocket. Its still very expensive, right . So we have to reduce the mass of what we put on rockets. And then when you land it on the moon, it weighs one sixth of what it does here on earth, right . Imagine, like, trying to dig as if you were on ice, right . It will just scoot across the surface. The scoop will not engage and you wont be able to collect anything. So the way the robot scoops up the dust is using this thing called a bucket drum. And its got a kind of spiral in there. And if it turns it one way, it scoops the soil, which gradually works its way towards the middle and stays there. Like that. And then when it wants to unload. It turns it the other way and it all comes out again. We put them on opposite ends of the robot and when it excavates, its using both sets of drums at the same time, but theyre digging in opposite directions. So one is pulling it that way and one is pulling it that way. Right. And pulling itself down to the surface. Yeah. One of the main dangers faced by Extraterrestrial Rovers is getting stuck. So, as an added bonus, ipexs scoops and arms can also help it to get out of a hole or flip it over if it takes a tumble. One of its other defences will keep its cameras free from all that electrostatic dust, which will cling to every part of it. Its lenses will be fitted with an electrodynamic dust shield. Simply apply electricity and the charged Dust Particles are repelled, keeping its vision clear. But after a while of going to and fro, we might want to stay a little longer on the surface. Robots like this one will prepare the ground for permanent buildings by smoothing and compacting the foundations. Do you have a name for this arm . Um. We call it. We call it meercat, actually. Youve always got cool names for these things yeah. Why . Its called the multipurpose end effector for regolith acquisition. Meercat. Transportation and. Yeah, yeah, thats it. You see, what worries me is there are some brilliant inventions you guys havent bothered with because you couldnt think of a cool acronym. A cool name. That is like one of the. Its very important to have a good name for your projects because it, like, represents the soul of the project, right . Now, just like the fuel situation, we cant take Building Materials with us to the moon either we have to make our structures from moon dust. These bricks and blocks and bars have all been made by mixing and melting regolith with plastic. In the future, giant sd printers will build shelters to protect those living on a world with no atmosphere from radiation, asteroid and micrometeoroid impacts, moonquakes and temperatures ranging from 100 to 200 degrees celsius. Even Replacement Parts can be made from regolith. So this is a wheel that has been printed with regolith and polymer. 0k. This is another example of what we can do if we capture the resources from the moon. Now, do you know, ive seen and held wheels for rovers before, full size wheels, and theyre really light. Right. But this is really heavy. Yes, this is the opposite. Because those wheels that are light, especially if youre sending it on a rocket, they need to be light because its expensive. This is heavy because its made on the moon. And heavy wheels are a good thing, i guess. Its better, right . Especially for a digger. Like the more weight that we have on the excavator, the better its going to perform. Would you believe you can even make rope out of regolith . This is made from basalt glass really, really thin fibres, a bit like optic fibre. So you could even make rope out of moon dust. These are hopeful times for space exploration, but its always been a risky endeavour. Im I Odysseus Lunar Lander separation confirmed. This year, weve seen three probes sent to the moon. Two made it, and both of those had, shall we say, awkward landings. And the Artemis Mission to put boots back on the lunar ground has been pushed back to 2026 at the earliest. But nasa says Space Explorers need to take these setbacks in their stride. I dont see it as a disappointment. Its very cliche to say space is hard, but what were endeavouring to do is highly complex. We expect challenges along the way so this doesnt surprise us and were pushing forward. It sounds really expensive to do space exploration. Is it, and is it worth it . So, yes, its really expensive. It was really expensive for us to explore this planet, really expensive to lay rail infrastructure, to lay highway infrastructure, to put the infrastructure in place that allows us to travel in air traffic around this globe. Its absolutely necessary for us to lay that Critical Infrastructure for going to space, because what we learn in that endeavour is tremendous. The exponential growth that weve seen in the world in technology is because of great endeavours like this. Its absolutely worth it. Here in the united states, every year the general population is spending as much money on potato chips as our budget is every year to go out to the moon. Thats a good figure. The motivation may be different to that of the space race of the 1960s, but the size of the ambition is just as great today, as we shoot for the moon once again. Google has confirmed it has started restricting election related questions on its ai chat bot. If a user asks the chat bot about a Political Party or candidate, it will tell them to try Google Search instead. They have started rolling out the measure in india, the plan is to expand it to other countries where big elections are taking place. The European Parliament has proved the worlds first framework for a regular to the risks of ai. It classifies products according to risk and adjusting scrutiny accordingly. The laws creators say it will make the tech more human centric, howeverthe it will make the tech more human centric, however the act still has to pass several more steps before it formally becomes law. A Surgical Team at a hospital in london have become the first in europe to use applevision pro to perform two microsurgery spine surgeries. The headset allowed some of the team to have touch free access when setting up have touch free access when setting up the surgery and offered them visualisations that were previously unavailable. And fancy wearing sunglasses that can quickly swipe to become Reading Glasses . Well, deep optics have you covered with their newly created 32 n glasses. Users can transition between the two settings thanks to liquid crystal lenses, containing pixels and tiny electronic controls. I never dreamed that i could become an astronaut. Im talking to kayla barron. One time resident of the International Space station and now part of the artemis crew, the team who are preparing to go back to the moon. First time i looked out the window of our capsule. I6 sunrises and sunsets each day over our beautiful planet, really fundamentally feeling this interconnectedness. Everything each one of us does has an impact on the people, notjust immediately around us, but on the entire planet. That inspired me to be really deliberate about, what contribution am i going to make to leave a better, healthier, more connected more Cooperative Planet . What inspired you to become an astronaut . I did decide from a pretty early age that i wanted to serve in the military, and ultimately found my way to the Naval Academy and to the navy and to the submarine force in particular. And i met an astronaut at a Navy Football game, and hearing her storyjust reminded me so much of my experience on the submarine. And All Of A Sudden it clicked in my head, wow, the International Space station is a submarine in space. And i told her that and she said, it totally is. Its exactly the same. You have these really complex machines out in these extreme environments that are designed to keep human beings alive in a place were not meant to be, really, which is deep under the surface of the ocean or in the vacuum of space, and notjust keep us alive, but also allow us to accomplish a mission, do something as a team thats of value to others. What do you think it might be like to live on the moon and then mars . Well, the moon is beautifulfrom the Space Station, first of all. When the sun is reflecting off this sphere, its notjust. You know, a crescent moon, a sliver in the sky. It felt like you could just reach out and grab it, and i think made me realise how incredible it is going to be to send human beings back. And theres incredible scientific questions were going to be able to answer. Were planning to return to the moon, but this time to the lunar south pole. So well be exploring a different area than we visited during the apollo era. Answer some really fundamental questions not only about the moons formation and its geology, but about our entire solar system. You are part of the artemis team. The artemis 3 crew is the one, i suppose, that Everyone Wants to be on, because i think thats the one where the people are going to stand on the moon. Are you in with a chance of being on artemis 3 . Of course. Everyone in our office dreams of the opportunity to be part of those crews. You wait and hope. But the really cool thing is, even if youre not in that seat on the flight, you get to support them and be a part of the team that makes that happen. The artemis 3 mission, they will put the first woman and the first person of colour on the moon. Im guessing that those two people will become as famous as Neil Armstrong. Put yourself in her shoes, even if its not you. What would that represent for you . For humankind . You know, i think that moment will really represent how far weve come. You know, we did Amazing Things in the apollo era, but not everyone had the access to those opportunities. There have been women in the Nasa Astronaut Office for a really long time doing really incredible things. So well be standing on those womens shoulders. The first woman to command a space shuttle, the first to do a spacewalk, the first to command the Space Station. And when we look around at the diversity of our office, its really incredible, like, who we have around us. It will be this incredible, historic, iconic moment that i think young women and girls around the planet will look to as an example of the fact that you can do anything if you work hard and are supported by the systems, the communities around you to have an opportunity to achieve those goals. You might have seen space food before. But what about space plants . If nasa wants its astronauts to stay out in space for longer, theyll need to be able to replenish their own food supply. This is nothing new. Astronauts have been growing crops in space for the past a0 years. But theres still an awful lot that scientists are trying to learn about space farming. We have things like radiation that we have to deal with. We also have issues with microgravity. Plants have learned how to detect gravity with their roots and gravity sensing organelles in the plants, and so they know how to use these cues. And without these cues, they have to re adapt to this environment. So, without gravity, the next cue that they use is light. So how to go up and down, how to orient themselves is based on light now, cos they dont have gravity. Water behaves very differently in microgravity. It has a high surface tension, so it likes to cling. And when the water clings to the roots, it prevents the roots from breathing. And so the plants can experience things like drought stress. They mayjust look green to you and me, but plants appear very different when viewed in the infrared and ultraviolet parts of the spectrum. And the scientists here are learning how their appearance changes under different types of stress. Here in the Plant Processing Area were giving the plants a stressor. So in this case, were reducing its watering. Because on the station we know its difficult to water. And so we can identify through our imaging project, using infrared and visible light as well as fluorescence, that stress. We take all this data and to make that association we use machine learning. Then we can associate the wavelengths that are most indicative of that stress and include them in a camera that would monitor the plants on station. This is where the plants live when they get up there. The veggie unit. This is how they grow stuff on the International Space station . Yeah. Its a simple led system as well as a bellows, so its open to the crew environment. We have two of these and six plants each. So you can imagine were not making a huge feast, but its enough for a nice serving of lettuce. Lovely salad. Yeah. How excited are the astronauts that they can now have salad and not just space food . Theyre very grateful. They can have salad, weve grown peppers as well, and they can even have flowers because weve grown zinnia on space. Now, there is a knack to getting these seeds to sprout in space. The way you grow plants on the International Space station is using this, which is a plant pillow. So this is the wick that sucks the moisture up. You plug your water source into here and you fill the bottom with soil, and then you get your tiny seeds, which stay in these Polymer Wrappers so they dont zip off and you lose them around the iss. And you pop it in here, and 28 days later. Get yourself a lettuce. Aside from the obvious benefits of creating a renewable food source, there are all sorts of other advantages to growing plants in space. Gardening is very therapeutic. Its something that the astronauts would say, hey, you know, let me take care of something green. It makes them happy. Plants produce oxygen and they recycle waste, they recycle water. All this fundamental stuff together will make them a very important organism to take with us. When were living on the moon and when were living on mars, what type of plants will we be eating . We would like to have things like nuts and citrus, but again, theres still so much we dont know about how those plants adapt to the environment. The current goal is to use hydroponic systems, which rely on water based Nutrient Solutions instead of soil, which is heavy and expensive to transport. But in 2022, scientists showed that plants can grow in lunar soil, regolith. Which kind of brings us full circle in a way, doesnt it . If we want to live on new worlds, we need to use the resources that they provide us instead of taking more from our home planet. This has been a fascinating trip to nasa, a place which will one day help us put builders, miners, and even farmers on the moon. Hello there. A wet morning for many so concerns of localised flooding and that will be an issue through the week as ill show you in the next minute or two. But what a contrast between yesterday morning when we started with a widespread frost and some sunshine. Today, temperatures have been much higher because of rain has moved in this massive cloud here as well shrouding the hills and the headlands in fog has given a very murky start to the day, but it is starting to clear in western areas. And so for the next few hours, central and eastern areas got some heavy rain and hail, fog, the combination making some really quite miserable conditions on the roads, lots of spray and standing water because there is nowhere for that rain to go. There are Ground Flood Warnings out at the moment, but as we get towards lunchtime, we should see the back edge of that Rain Clearing into the north sea. Brighter skies follow. Therell be a legacy of mist and fog around the hills and coasts, particularly in the west, but also east and scotland. But in between, just a few sharp showers and temperatures rising higher than they did yesterday, 16 or 17 in that stronger Spring Sunshine now. But that could trigger some heavy showers and the odd rumble of thunder. The showers will continue through this evening and overnight, always heaviest in the north and the west, tending to ease off a little bit further eastwards. But theres probablyjust enough cloud to keep things relatively mild again overnight. Not as mild as the nightjust gone, but five to seven degrees celsius and perhaps a little bit of mist and fog. But actually, monday looks like for many of us therell be a drier window of weather, just a few showers. Yes, rain returns with stronger winds for Northern Ireland later. But in between, therell be a good deal of dry and bright weather, some Strong Spring sunshine coming through those uv levels starting to get into the moderate category, 14 to 16 in that sunshine. But then monday night brings us more rain. As you saw for Northern Ireland through the afternoon and evening, pushing across the rest of the uk and a Weakening Band as it reach the southern eastern areas. But theres another Pulse Developing on it as we go through tuesday and into wednesday. So that is a concern. We could see another dose of rain. This is todays rain. This is the Rainfall Totals as we go through the week and not that much for scotland and Northern Ireland today, but certainly so late tomorrow, overnight, monday into tuesday and another pulse on wednesday. So a good 30 to a0 millimetres in many western areas. But even in the east, 10 to 15 millimetres on to saturated ground because it is an unsettled looking picture. Keep up to date as ever on the website with the warnings. Live from london, this is bbc news.
