force they have used themselves as part of the scientific community that many of them have gone to space with less than perfect health and have been great examples of how for example laser surgery on your eyes as affected by space flight they all want to participate in this they are participating and the fact of the matter is quite honestly when private citizens go to the space station a lot more people hear about the space station than otherwise it's just one of those things that they captures the public's attention part of nasa is mission is to encourage to the maximum extent possible the commercial use of space and in fact showing that there's a market showing that there are people willing to do this and showing that you don't have to be a career military fighter pilot the right stuff kind of person that plays a huge role and i think that's exactly the sort of thing that ends up helping the space agencies of the world as well ok we'll get to the to the other economic areas

the best way of mining in that a while at the moment we have just seen the dragon spacecraft go up to take supplies to the ais that was a significant moment. however it was it was a small pots of what is otherwise a vost state and surprise and without state capital it seems that at the moment no private and devised could exist you can point to companies like space x. space x. has a contract for services to deliver cargo to the space station but the capital that it was started with has come from its founder. and so this is an inflection point this was not always the case you're absolutely correct the for the first thirty years of space it's all been controlled by the government but we're reaching a point now in fact i think the flipping point was in the mid ninety's when private commercial expenditures in space finally exceeded government and that was of course driven by the satellite telecommute. patients market and things like that no one

would argue that those are successful businesses but we're reaching a point where commercial enterprise is creating its own space program and it will stand on its own it has been well noted that in the past year and a half the have been a number of worrying mistakes with russian space programs a supply rocket up devices fell back to worth a mission to one of the moons never got out of orbit and its course in high profile resignations and will likely lead to a lot of restructuring in the russian space agency serious concerns is this technology that's going to take people up that good enough the fact of the matter is that despite reaks recent hook ups that may have occurred on different types of launch vehicles the soyuz spacecraft and rocket have the best safety record the best history of being a proven technology for reliably taking people to and from space in human history there is no other vehicle that comes close nasa uses this vehicle itself to get to

space so while there is always room for improvement and while i'm sure and highly confident that the russian space industry is is going to great lengths to to to make sure those things don't happen again spaceflight is inherently and they are an activity that is risky and so the risk is managed but it's never going to be perfect at the end of the day i think there's not many people in the world who would want to go to space who wouldn't feel comfortable flying on the soyuz the key technological breakthrough that we need is rapid and cost effective reusability like flying in an airplane when you land it moscow airport where you landed new york airport they can turn the plane around in a couple of hours and leave actually less than that this is the problem you what you're saying to me immediately i think of the shuttle there is no shuttle you can't reuse soyuz we're going the wrong way. so the shuttle was a vehicle that was incredibly high performing it was an amazing feat of human

engineering but it really wasn't reusable i like to call it rebuild a bowl certainly parts of it were rebuilding all certainly some of it was reusable but there was an incredible number of man hours that had to go into certifying that vehicle for re flight every time it ended up being far more expensive and far less reliable in terms of its reusability that's why i use the word rapidly reusable so the shuttle was not a great example of that however many of the vehicles that are being built now including for example the falcon in the dragon by space x. are designed and the c s t one hundred by boeing to be reusable ten times one hundred times a thousand times and those kinds of advances will be the ones and it's going to take time that will yield those price decreases that will eventually enable millions of people to go to space every year there is one of the costs that perhaps hasn't been looked at enough at the moment there's already a lot of criticism leveled at people flying all over the world for the holidays

about emissions about pollution that not many rockets launch from of the moment but they certainly aren't environmentally friendly the ones that launch if that program is going to be expanded one could be the environmental costs of such space tourism . so when we calculated the carbon emissions of a soyuz launch it ended up being something like a fraction of a transatlantic air flight so it's actually not as much as you think the fuel on the space shuttle was liquid hydrogen and liquid oxygen and the exhaust was water so these are not the kinds of things that are really going to affect our carbon emissions and our environment as a whole even when we get to the point that there are literally tens of thousands of launches per year it's a drop in the bucket compared to all the other forms of emissions and pollution osha wants an issue that will will take shape in time we'll see how that one puns

out the tourism isn't the only idea that you've got on the on the books as it were you also mentioned earlier mining asteroids and this seems like a lot more sort of hard nosed commercial idea just trying to paint a little picture for us a lot of people can't really invision envisage this perhaps from pictures from animations that you've seen perhaps that there are you know asteroid belts but i don't think there are any asteroids that close to earth because that's the kind of thing that people get scared about the of from destroying earth so what what kind of distances are we talking about how is this actually with this actually look a fully running asteroid mining operation that wonderful question so in the solar system we have literally hundreds of millions of asteroids the vast majority of those asteroids lie in the asteroid belt the asteroid belt is between mars and jupiter one hundred million miles away or more however there is a small but not insignificant population of what's called near earth asteroids

anywhere between ten and twenty percent of the material on them are what we call volatiles what that means is most of it's water water ice and water is great because when you break down water into its constituent parts you get hydrogen and oxygen not coincidentally of the same fuel. all the space shuttle used to go to and to and from orbit and so we first want to use the asteroids to build propellant depots in space that is gas stations we want to be able to reduce the cost of space exploration by allowing spacecraft and spaceships to feel up no matter where they go and by doing that we will enable a space economy for all different kinds of businesses this is the second half of the equation of how to reduce the cost of space travel once we have the capability of propellant depots in space moving asteroids around becomes much easier and then we can go to the more valuable materials the higher cost per ounce materials for

example the platinum group metals now fifteen fifteen hundred dollars an ounce on average you have platinum palladium rhodium osmium iridium and the asteroids are chock full of these materials they appear in concentrations orders of magnitude better than the best platinum mines on earth in the asteroids and start to seem like a skeptic but i think i'm not alone in the image of of us sending out teams to try and move asteroids to try and land on them really starting to see much the realms of science fiction i mean they managed to recently land on mars but that's really the very limits of the moment of our capabilities is this really a serious proposition how on earth would you go about doing something like. so let me be the first to admit there is a long list of technical challenges and it's going to be very hard this is something that we don't know all the answers yet but we do know is that there is no laws of physics that prevent that these are pieces of rock out there that for

example something the size of the international space station could be worth two hundred billion dollars and so where there is a pot of gold at the end of that rainbow there will be a way people thirty years ago thought drilling a hole down into the bottom of the ocean and pulling fossil fuels under the north sea was impossible and now that's what we do as a matter of daily practice well we will have to see whether that does indeed transpire big promises but certainly big ambitions and perhaps big achievements as well whether there will be a future for space tourism and indeed space mining is down to people like eric and as mr anderson thank you very much for joining us thank you it's been a real pleasure.

second place and we didn't take our chance at home to celtic up with their for tuesday's clash it's very important for us before you have a firstly we're playing at home and we can't afford to lose here any more if we want to make the knockout stages. the pressure is certainly building on emery with his side losing the last three games languishing in mid table domestically one of the champions league there without a point after the first two encounters should be a part of their thinking positively ahead of their game with benfica we can't afford to do anything else i'm sure that my team will put in a good performance against them in a year we've had some bad results but there have also been some positives us and we're looking at these positives and i'm sure that this will help us together result we need on tuesday. meanwhile been fico coming to this clash having lost just once all season and that being a two no reverse against barcelona. the portuguese and feed have a good combination of youth and experience and they are seasoned european campaign

to host the twenty fourteen winter olympics is due to the success of the many winter sports athletes it's produced and with the games less than sixteen months away many are getting ready now but the spot increased urgency to better prepare it's often been a case of having the right set up german the sixteen thirty five tracks and other infrastructure have been serving professionals and fools since two thousand and three the center was initially designed to hold international events of any level there are no other centers in russia that have as many certified tracks as germany six times we've held a stage of the ski world cup here and have already secured it for the season after the olympics the row the ski tour is just one of the many events that the complex hosts with some are also including triathlon and marathon competitions but it's impressive prix winter season where the center excels as it can produce its own snow even in plus temperatures. you know i've been roller and cross country skiing for a while and i can see this complex is one of the best in russia it has interesting

courses and is kept at a high international level what's best is that it's part of a better developing roller ski and crosscountry. something that's been sorely needed. so the infrastructure may be slowly popping up on the russian landscape however there's still a lot that the cross-country and roller ski federation's wish could be sped up and improve the. eye of course want to see more ski complexes and courses for skiing built around russia because it's the main create syria for further developing these sports where trying to how cultivate these sports in various regions of the country but there's still plenty of work to be done. but for now it's places like germany that will have to lead the way for future generations. more complex maybe a one stop shop but that's in the realm of years marathon runners and winter sports in general but it's also a great place just to come and relax and with cottages that have their own personal
