such as w, w, f, and a number of governments. one focus of the company's work is monitoring the impact of land use and climate change on vegetation. satellites can capture images of large swathes of land vegetation in a site. hell can be tracked from season to season with thrown out astronauts say they have a very different relationship to earth once they've been to the i assess. the view from a satellite is a bit similar. we can see how africa is doing or south america. the view from far away enables us to see connections more clearly by the victory on the copernicus, satellites are big and heavy, they weigh tons, it takes years to build them, and each is unique. many components 1st have to be specially developed that makes the satellites expensive, hundreds of millions of year as in each unlike

many satellites. they can be as small as a wine bottle. the advent of small satellites marks a new era. there are a lot cheaper, but still provide important services. planet labs is an earth imaging company in san francisco that already uses many satellites to photograph the globe. students throughout europe are learning to build the little devices. one class of small satellite, nano satellites. a team at berlin's technical university devised a project to deploy 4 of them to enable faster transfer of large amounts of data. they were launched 2 years ago.

small satellites have the potential to revolutionize earth monitoring, as well as global telecommunications. to start up, smart small satellite systems does what its name suggests. it's a cube sats can exchange precise information about their orientation so as to point in the desired direction. they cost tens of thousands of euro's a piece in your tooth. it is the miniaturization of electronic components that enable such development to lytton satellites may be getting smaller, but that doesn't mean their overall performances are declining. one can deploy a lot of small ones for the price of a big one. if a company has launched 4 of its cube sat so far, they're flying in formation to test 3 d. typologies for scientific measurements. to do that, they have to communicate with each other,

negotiate and organize their positioning autonomously. this test is a significant step towards creating intelligent 3 d. satellite configurations. one application could be mapping the ash emitted in a volcanic eruption that would be of great value to commercial aviation. small satellites often put together using standard components. so it's easy to make a lot of them and also to switch out components depending on the intended use of space, x. is planning to send 12000 small satellites into orbit as part of its starting project to provide internet to remote locations around the world. big projects like that, spur the automation of satellite manufacturing. it's comparable to what's happened in the auto industry. in this regard, us companies are far ahead of ones in europe. we in europe shouldn't just give up,

but aim to be players in these markets of it's where the future lies. the economic and commercial potential is going to be huge. after he's put into the i got it sort analysts say the space industry is set for stellar growth. revenues in 2018 amounted to $360000000000.00. some forecasts say they could reach $2.00 trillion dollars in 2040. rocket factory obs. but once a piece of the expanding space pie, it's developing a launcher for small satellites. a pretty 2 rocket, specifically designed for that purpose. until now, small satellites have to hitch a ride if there's room. when big launches such as arianna set off into space, it's not very expensive, but the waiting list can be long. but

in cost launches a big launcher is like a bus. you have to wait till everyone's on board. a small launcher is like a taxi, it tick sure where you want to go more cheaply and efficiently. that's great for creating a small satellite constellation. about 100 companies are developing many launches. many will probably fall by the wayside. 3 are based in germany. rocket factory aims to offer affordable and flexible satellite launches. 10000000 euros a shot compared to 130000000 for an arianne. to keep costs down, its launchers will contain many standard components from the auto industry. but it's designing the propulsion systems from scratch and will 3 d. print a lot of the parts yet

big launches such as arianna, a very complex and post lots of expensive custom components. they take ages to build. by contrast, our f.a.a. aims to develop and deploy its 1st launcher within just 3 years. will be financially viable with one launch a month. but we want to see a launch a week that the whole thing should be. so industrialised and automated that it's no longer anything special. flying between braman in munich is not a big deal, but it was a century ago. we want to see the same thing with rockets. keep an off site. small satellite launch vehicles are set to make getting into orbit more affordable, potentially opening up the heavens to a whole range of new ventures. the vastness of space presents another problem for any potential business activity there. the logistics of covering huge distances in a practical amount of time when there was some sort of system like teleportation

that works in star trek. but could it work? in reality, my colleague has been investigating a long time ago when space ships were made of paper plastic and it's no use powdered allen minium. during the dean materialization process, people and things were magically beamed about in star trek films. how nice would it be if we could be in ourselves around the globe teleportation instead of airplanes and c o 2 emissions? think about how beneficial it would be for the climate along into based physics and facts. teleportation is no longer science fiction. i'm always surprised about all the weird things that happen for the money where your heart is

a quantum physicist at the austrian academy of sciences. his excursions into space travel are just a hobby work. he explores the weird and wonderful world of teleportation of quantum teleportation to be precise. as a, having watched our trek, for instance, people imagine that you somehow beam matter or even energy, because that's how it's done on the show that people disappear in the transporter and then reappear on an alien planet. when the similarity is that the system rebuilds the object identically in another place, or what's more at the exact same time or instantaneously regardless of the distance involved. that's how the quantum world works via quantum entanglement. einstein thought it was pretty spooky transferring information faster than the speed of light. so does this mean travelling not only with 0 emissions, but also with 0 delay?

what happens with quantum teleportation? is that really just that you want him information in this system is transferred to another place onto another identical system. with the matter itself, atoms, or photons, or whatever it's made of does not get transferred so it doesn't disappear. i think what does disappear is the information it gets destroyed still. so if 2 quanta are connected this way, they can exchange information without a moment's delay. but not the matter. it really is just the information. ok event. couldn't i just split myself into quanta and send their information to another entangled quantum cloud? i mean, then i would just need to be reassembled correctly, right?

let's just say that right now, we don't know of anything that would fundamentally speak against it, but it would have to work in a completely different way. but we'll need completely different setups than what we're creating now with the other. if i could build a device that could do this and you'd ask me whether i would put myself inside it, i'd say no. so mr spock would probably have to book get beamed into glittery shower of alan minium gray. like in the old days. and don't forget the enterprise at least spread through the universe, powered by an anti matter and hydrogen engine with not even a whiff of emissions. by the way, a piece of trivia for you, the words you me up, scotty. whenever said precisely in better form of the static, serious, maybe it will work with the me aboard and

that's all from this edition of may see you next time. until then. good bye and keep watching the skies. i'm going to
