And this week Dr Karl is having a little holiday but that gives us the opportunity to welcome back Bianca Grady the science journalist and author of Hello Bianca how I write how are you very well thank you it's super to have you and Lisa Harvey Smith don't totally Zahavi smithy astrophysicist Hello Lisa Hey Ron How you doing fake good very good so we find you both down down south and I speak I speak in a kind of global way here because you both and both in Australia today but I guess you too would have been just watching that space x. Recovery with your most high and open and we certainly were it was it was a remarkable thing wasn't it Lisa Yeah it was an incredible incredible sort of you chief sensation in fact 2300000 people signed into the biggest of a live stream. The 2nd biggest ever live stream it was this event across this Wednesday where they launched this amazingly new powerful rocket cool fall can heavy and just such a such a beautiful sight and lovely little touches there with David Bowie and so on. Right and and of course the cars with the with the camera behind it which which made me think I must admit made me think for a while that it must be. Not a fake exactly but it was it was produced by space x. You know as a an animation you know it would be something that wasn't quite real but it will you know evil musky in amazing guy the guy who runs space x. Is a c. Is made his money in software and things like Pay Pal but he's actually got a background in physics as well so he's a chief engineer so this thing but he's definitely a showman as well and the little touch of sending his sportscar into space is really a clever bit of marketing I think that there is a serious side to the launch and it really is a great leap forward because you know NASA the mind of course doesn't have any way of really sending things into space and that's incredible that now private industry is taking over this month at the moment when the American nationals want to get to the International Space Station they go on the Russian rockets and you know this this is really a huge gap in the market that people like space x. Have really started to exploit So I think it's exciting for the future quite quite extraordinary of course we're hearing no that the idea to actually take people up to the space station is really very achievable with with this technology . That's right I mean you know this particular rocket this was designed to take big highlights that's why they they shove this car in there is a bit of a gimmick but really the serious side of it is that we will now be able to launch largest satellites and also classed as a satellite so one of the ideas is to send up a large number of very small satellites to do scientific experiments or even one of Space X.'s big idea is to spread broadband right around the world so the whole of the world has broadband coverage and what you do is you chuck thousands of little mini satellites around the earth and even a above the Sahara desert or the remote areas of the Amazon jungle you'd have you know really great broadband network coverage so this is something that could really change the world for everyone it's exciting. But should possibilities there for questions but one other thing I'd like to ask about before we kind of open everything up and like Bianca it in the is the strange behavior of dark matter you know we do get questions but about dark matter but you've you've been looking at some reports about dark matter that's behaving a bit unusually. I think this is Lisa not me Oh I'm sorry yes it is Lisa you're actually reading yes I believe yes not you know Bianca where promise will come to you very soon but but as I understand it at least has been been you know hoovering up some some facts about dark matter for us but sorra it's the weird stuff that makes up 80 percent of the universe we don't know it's there but we know it's there this it's got so many way of properties this is the stuff that makes galaxies orbits faster than they should this is the stuff that brings together super clusters of thousands and even millions of galaxies is strings together the cosmic structures that make a giant sort of spider's web shape the cosmic web which is the giant super structure of the universe but it's not behaving the way it should so as a being a weird little study done that found that in nearby galaxy clusters there is a disk shape instead of a spherical shape of all the little galaxies there that are all getting the logic galaxies and after areas of dark matter say this should be a big spare ical distribution so these things should be spread out in all directions in the sky but new studies have shown that in the nearest 3 galaxies. That little satellite galaxies that was around us like planets are all lined up in the disk so this is not a way dark matter should behave and it's really turning ideas of our universe on its head. Maybe we can talk a little bit more about that. Let's let's go in and start this whole business 85 or 5 a few texts and 5909693 if you'd like to give us a call upon a b.b.c. C o u k. Now then. Bill in Glasgow says as the Earth has an orbit around the sun does the sun itself have an orbit to. Attack in the world of Galileo I get I guess that would have to be a question for you Lisa what would you think yeah I mean the idea obviously orbits around the sun along with all the other planets in fact the Earth orbits around the sun's center of gravity which is extremely extremely close to the center of the sun so in a little way the and the Sun orbit around the center of gravity so that the Earth has a tiny little gravitational tug that causes the sun to wobble but then the sun has its own orbit around a galaxy the Milky Way So does this huge giant circle over millions of years around the galaxy too so yes we do have a big obit that takes us on a huge Secu assist journey around the Milky Way but it also has a tiny little tug from the that's what's nice. And this is from Phil the lorry driver who's been writing us an email he says after watching you on mosques totally amazing test flight of the 4 can have it 2 days ago got me thinking about the fuel that they use nowadays and rockets I understand and days gone past with rocket engines such as that used in the main engine of the space shuttle they do use oxygen and hydrogen makes it together and light and this would also give the added benefit of making it rain after a lunch or a test firing of the rocket Nowadays I hear the fuel is much more efficient Sadly after seeing the 1st stage break away and watching the 2nd stage engine burn for a considerable a long time considering the size of the thing can you tell me what you know about the fuel use on modern day rockets. Phil says probably checking my load over with the door wide open so I can hear you know underwear Phillis tonight anyway. I'll give that I'll give this to you Lisa 1st of all but I'm sure Bianca might have a few a few things to add to this too. Yeah that's a really good question I just read read a really interesting article actually about this from an environmental scientist here in Australia and there are concerns of course with these huge rocket launches that there was a lot of energy you could either say used or wasted the pending on your point of view you know the the scientific progress does take a lot of energy and when you're trying to launch things from the air the really is no way around that as you say that in the sort of Apollo era in the 1960 s. Used to be a lot of hydrogen oxygen. Rocket fuel used and of course when those come together there is a huge amount of energy released and in fact you could say that hydrogen fuel is is cleaner Some people say it just creates a waste product of water but in fact you've got to create the the liquid or frozen oxygen you've got to create the liquid or frozen hydrogen and that takes a lot of energy and that takes fossil fuel so which have a few use it it actually creates quite a bit of pollution but they're using more kerosene in the modern space x. Rockets I believe and that's that has its own environmental concerns of course safety concerns so whatever you use whatever be using There are the environmental impacts I suppose and there's also the energy efficiency so these rockets are much more efficient there are 3 years of all as you saw the. The boosters were actually jettisoned after a couple of minutes and they 2 of them landed safely in Florida and one of them attempted to land on the ocean and unfortunately crashed into the sea so you know we're getting there with with increased efficiency new fuels but really we're not at the stage where we've got an environmentally friendly or sustainable way to get into space but hopefully we'll get there. But if you were going to you know achieve sustainability Aliso where what direction would you go and would you would you try to do something with water yeah it is it is very difficult as I say that there are many proponents for the hydrogen fuel economy but the problem with hydrogen fuel it's beautiful and hydrogen and water sorry $100.00 option come together a lot of energy is released it just creates water but you've got to get the hydrogen in the 1st place you've got to create it just like creating. You know things like solar cells are very environmentally friendly in one way but they have heavy meant minerals in them and things which pollute the environment so nothing is is coming for free it's very difficult to see where we get free and safe critically the safe part energy from because as we know nuclear power creates a lot of beautiful energy for us but it has its safety concerns too so really what direction do you go in well you've got to just keep trying and the more energy can get the bigger the explosion you can get so that's it's a bit of a conundrum for us. Helpful note here by the way from Paul in Shropshire who says that the 1st stage of Saturn 5 was kerosene and liquid oxygen and the 2nd and 3rd stages were liquid hydrogen and liquid oxygen quite right is a fountain of knowledge there yes he certainly is he certainly is. I'm I'm on the hunt for a question for him. For what can I say actually probably just jump in there just on that hard liner and your yes come on I will. Never want to pipe down but hydrogen is really being investigated now as as a means of effectively transporting renewable energy so for example solar solid generated electricity or solar generated energy because at the moment it's very difficult to transport electricity of a large distances because you have transmission losses and things like that and so one of the processes it's being looked at is in parts of the world that have an excess of solar power being one of those you can actually use solar energy that's generated by the sun through photovoltaic you can actually use that to effectively split water into hydrogen and oxygen and then you can bottle up and compress the hydrogen and then you can transport the hydrogen and so you're effectively using the hydrogen as a means to transport solid energy even though it is a fuel in itself so it's kind of becoming a bit of a proxy I guess but it doesn't mean it doesn't solve the problem there is still as Lisa said the solar cells to begin with have their own environmental cost and the compression process but it you know does as well require a lot of energy but it's certainly hydrogen is one of the I mean people keep talking about 100 economy and that's one of those areas there's a lot of interest in how we can make use of hydrogen for the very reason that when you consume hydrogen as a fuel the byproduct of generally relatively benign. You know. Looking at the. Mosques Tesla Roadster Phil Reedy says what about the tires on the car Surely any air in there would have expanded to a huge degree in the extreme low pressure in space are the tires strong enough to counter this I seem to recall the lunar rover having unusual airless tires for just the season someone we talked to yesterday said that they didn't inflate the tires Any advance on that the anchor Do you know I actually don't Naru that so that would make perfect sense if they were filled with air presumably that would decompress and it was hacking only. Reds and rubber all over the place Yes and under all of Iran masks hard work so I suspect without knowing any with already that that's something I would have I fully thought about well in advance otherwise I think You Tube would have had quite a display of as he said exploding shreds of rubber. But yes I actually don't know Lisa have you have you know anything. No but having taken a bag of crisps up to the top of a very high mountain in Hawaii and then expanding to double the size I can definitely vouch for the fact that you couldn't have. Regular ties in in in the Tesla I guess I think with the lunar rovers they they use some sort of. Sort of hard material which had a little bit of spring in it so I would imagine they would have thought about this and I think of a really interesting question to ask a lawn maybe could get him on Twitter or something and. Fire him off the question because that's not something I haven't come across as a really great question. And the other thing that I was asking yesterday was how resistant the car would be to space Deborah and so on I mean it's going to get pretty doing the opposite to. Where you would hope so wouldn't it be a good way to catch it and a good way to actually study how much there is be quite interesting to get some photographs as it goes along and see how many little dents in the bumper because you know if you driving down the m 6 or something and a piece of gravel comes up from a lorry you know you can crack you wouldn't screen so much and that going at hundreds of kilometers per 2nd you're going to get a car full of holes pretty soon you know Musk was pretty confident that his car would be up in the orbit about a 1000000000 years I think he said so I'm kind of magine how many holes it would have been by the time I got to the hands of a killer. Yeah like. Quite a bubbling wondering what they've put in in the in a human figure that's sitting in there in the same whether they're put some kind of ballistic gel in there you know all that that amazing star is that star Joe that Joe was constructed that resign used to catch a stardust from the back of an asteroid where they feel they feel the Manichean a car seat with something that would actually be able to track particles as a kind of an ongoing science experiment. But I think retrieve it if it's an ongoing science experiment I'm sure we'll catch up with it eventually where we think the net the hope that someone will be able to pick the car up as I where did you leave it I think a part that got me my own way. But there is an interesting interesting point though right that you know space debris is really a huge problem near the end of the in low earth orbit but you know it's once you get out into space it between the Earth and the moon there's very little debris at all and then as you go out even further we really haven't crashed a lot of things out there course Apollo 13 famously blew a gasket on the way to the moon but once you get out to Mars it's really very little out there so you'd mostly be natural things like rocks and so on which would probably just go right through the metal I imagine go out the other side. And did they say any more today Lisa about how it got through the Van Allen belt because that was their big concern wasn't it but it was on its way to this fabulous elliptical orbit but it had to get through the Van Allen Belt furnished That's right I think the Van Allen belts for training on listening to hasn't heard of them as. A region of radiation which gets trapped so the radiation comes from the sun and the sun's emitting light and heat but it also emits charged particles like little protons and electrons parts of atoms that come from the interior of the sun and these are flown out very. Uniformly but also in large solar fl
