your dining companion says t actually that hamburger is not made from house. it's made from golden retrievers should meet. 2 2 2 2 2 2 in meeting cultures around the world, people learned to classify a small handful of animals as edible and all the rest they classify as disgusting. a doc you series about our complex relationship with animals. the great meat debate . this week on d. w. and die. a said mr. 6 on february 6th 2018. the falcon heavy rocket took off on its maiden flight

2 and a half minutes after launch the 2 side boosters detached. 8 minutes after lift off, the pair touched back down in cape canaveral in a synchronized landing. it was another p r coup or space x and it's bound or ellen musk, who's become a leading figure in the burgeoning sector called new space in germany and elsewhere . a growing number of commercial companies are now building rockets. software developers use satellite data to monitor gas pipelines and forests. college students build miniature research satellites and launch rockets. and at the political level, rivalries are intensifying. europe is competing against russia and china to install its own secure satellite network. a new age of space travel has dawned

in 2016 and interdisciplinary group called tude sat, was set up here at the technical university of dom stop in germany. these members are working on small scale satellites, often as when i'm measuring just 10 centimeters wide. they're cube sats will later be fitted with sensors that can measure gamma radiation and charged particles in outer space. they also have a special outer coating who's a little of latino satellite, as retro reflective film, will illuminate, asked with a laser from down here and see whether the feedback identifies as his hands. i know it's the experiment because satellites and especially keeps answer, often get lost after the launch do. so you can't say which one is yours and on the, and we want to see if we can find our satellite ivanhoe, who had of his, he vincent cohen was fiano hom, as he, we can also create photo and video recordings from space which can mean more media

attention and coverage, yada of max on and that could get more people interested in space on less and fish . oh, man, auto science of a guy, son. in a few weeks, these students will be taking part in a college competition organized by the european space agency. or isa. an important intermediate test of their progress of the winners get to take part in an 18 month professional satellite design training program. remiss in his escal scans. the fall, we don't need to have done at all, but show solid groundwork causes about work which is thorough enough to show we've identified and addressed all the major issues article supported and that what's left or details yet on from is that the no, so yes, this is a big deal for us all. it's from wendy on bottom. as yahoo! search the dom shot university team comprises around 150 students drawn from various fields, physicists, computer scientists, mathematicians and electrical engineers. they all share

a passion for space. several have already completed internships with the isa, the german aerospace center, or other agencies under warranty. but when i'm putting on 12, i moved, i was in one of the control rooms and got to dispatch a command to a satellite, evident off to think that that satellite is out there and then it replies steal command. that's just amazing. just because i follow his muslim fellow, and i think it was when the space ex operations got all the media coverage that i thought i was. this is interesting and also kind of cool with it combined space and has good job opportunities. so one of singing come, many young people have found inspiration in space x. the american company founded by ellen mosque in 2002, over a decade ago, he was still building his 1st rocket launch site in cape canaveral. within sight of the famous nasa launch pad, as he was eager to show in company videos for liver. boeing,

helpful vehicle mosque was also keen to highlight 80 percent of all space x rocket components being built in house. the 1st rocket, the falcon, one was 100 percent privately funded and after a series of failed launches, musk focused on the falcon 9. the thing is the turbo pump. this is, this is the chamber nozzle. and there's always supporting structure in there with avionics and control of our for 3, june 2010. the maiden voyage of falcon 9. let's grab the rebel about the reward for years of perseverance and risk. taking that outcome died either musk hut off. good site doesn't. nissan must had a different approach or so he tried things without knowing whether they would work it and in fact, now he didn't have a initial sonia to falcon. things like falcon, one didn't work, not but he carried on dust. always. yes. and that's his real achievement. if a,

by his own account, he was close to going bankrupt, taught us adama's dish dunbar banquets again. space exxon among the shy space eggs has changed public opinion. the more i listened, although i always joke about, oh, the nasa t shirts. you see kids wearing to day that the st. how trendy, they are, and poke august casa, if you live euclid, i'm with whom love from the invoke the 5th, the and that's also thanks to space ex office. all kinds of us. the space exercised a space travel is now in its next chapter. after decades of being state run, the american space shuttle blasted off on its last flight in 20110. i left off the final lift off of it lamps, shoulders of the flight mark the end of protracted development cycles, and hugely expensive production. as shown in a comparison of rocket launches, launching every key low of that space shuttle into low earth orbit cost an estimated $65400.00 compared to rushes. so use rocket at just under $18000.00 per

kilo mole. europe's arianna 5 rocket cost a little over 10000 followed by space. x is cut price, falcon 9th, and then the falcon heavy that just $1500.00 per kilo at space ex, development and production or under the same roof. some rocket components are made of a light weight aluminum lithium alloy. the lower stage is reusable, which brings a range of cost related benefits. german companies are learning from this american example. their micro launchers as they're called, have a payload of between 500 kilograms and 1.3 tons. currently they're still in the development and testing phase. none have actually taken off yet. the photo from micro loan from nist us loops lesson. the advantage of micro launchers

is that hey, loads can be put into a specific orbit on scheduled lines. and even if they are smaller than the co snippets hint of a bigger rockets might be more cost efficient. in terms of price per kilo executed from but clients have to accept compromises there could because they're going exactly where other payloads are also headed. it's less now inflating the german teams promise a faster flight into space and that the satellite reaches that precise orbit desired by the client. but they likewise have to keep production costs low as the market has become highly competitive. give people who build from their over a 100 companies and start us worldwide offering their services by noon than so who's at the same time, there's considerable demand among satellite customers, but often suddenly conclude that demand means that satellites are booming in the new space industry. again, thanks also to space ex. movers, denton. well,

it's a since 2018 the company has been launching its star link satellites on a regular basis. these provides internet that can download a 100 megabits per 2nd space x is primarily targeting more remote regions of the world that don't have bast, landline access. there are already over 2000 starling satellites orbiting the earth . in january 2022, there were around 4800 satellites in orbit and that figure has since risen. almost 3 and a half 1000 were used by commercial entities. 150 served civilian purposes like research. 506 were government owned, and 411 were for spying and military purposes. the rest don't belong in any one category. satellites had become multi purpose. take the sentinel family operated by the isa, and part of the e used copernicus, earth observation program. the sentinels are used for monitoring the oceans,

measuring pollutants, and the atmosphere and mapping landscapes. farmers, for example, can use their data for vegetation maps. these tell them where their crops are growing well and where they aren't. game, where they need to use less or more. fertilizer with satellites are also helpful for monitoring gas pipelines. high resolution images reveal potential hazards on the ground. some offer accuracy to within 30 centimeters, but for now, this is still a niche market talk with and you saw suit that had availability for high resolution data right now is still limited because there aren't many satellites in orbit capable of delivering it in them on the ships abide, but if you look at planned missions, including those by imaging companies, you see that many satellites will be launched in the near future with precisely these 50 and 30 centimeter resolutions, which on ties

a centimeter office and hum. this level of detail means new space companies could also monitor the movement of goods at ports for example, or detect a forest fire before it breaks out an increasingly important asset in light of climate change. feed emitter stennis runtime, the many medium sized companies don't know just how much value there is and satellite data sensors and trans our vision and mission is to make people aware of this through various applications, had so platter muscle, something and dive. and we'd also like to cooperate with local authorities in the near future when combination empt on behalf of launched him together. low cost rockets in a satellite boom are feeling a new phase of the space industry. in 2021, spending amounted to $370000000000.00. according to market intelligence firm euro consult by 2030. that figure is set to rise to 642000000000.

the berlin air show or ella is one of the premier events of its kind in europe. new space is also a big topic here. i know i couldn't vote nickel. one of our clients is setting up a communications constellation around the moon and a certain famous american player has set their side on mars last and vizier soonest . warren, i was dancing. augustine investors from around the world are now interested in space travel. oh, and they use different develop and methods for faster and more flexible production solutions. this is mitchell had been, it's been sales, it's the dom, start students 1st time at the isla, just 2 weeks earlier. they found out that they had won a different international college competition as a prize there satellite, we'll get to hitch a ride on a chinese rocket. mutinous scottish no, actually we lost sight of this because the announcement was

a year earlier on the music channel august. so we forgot about it and thought we weren't going to hear anything any more other than all kind of traditional cult. oh, the said, then we got this really positive news set up as opposed to americans. irish mom, now they have to hurry to get everything ready in time for the launch. though, linda, that's the biggest challenge. it's extremely short notice for our mission to launch a satellite release. so that's what we're most worried about. my story. given the time constraints, the group are pondering the idea of getting other university teams to build individual components or the body of the satellite. in the meantime, their own research continues. here, they're visiting a company that is helping out with equipment and expertise. the students are fitting their satellite with the reflective outer film to enable them to later locate it using a laser on the cubes that had 6, our cube sat had 6 sides before are completely taken up by solar cells. one

partially and the other one is completely covered with the film nicholson opens up . we need to find out whether our film is suitable for outer space and has the optical properties we expect them develop. and in particular, whether the film reflects enough of the laser beam, they want to see how it compares with a regular household mirror, which throws back over 95 percent of the beam. it's time to test the films reflective capacity. the result 2.5 millivolts. the reading means the return beam is 2000 times weaker despite the very short distance. it's a sobering result. but even that low level of reflection, the students say, might be enough to locate the satellite hundreds of kilometers away. they also planned to attach tiny corner cubes to the exterior, to improve reflection, isn't even, and they're polished on 3 sides to ensure the light is reflected back where it came

from. the look of the kid with the commonly used in aerospace. no, but said this is state of the art instead of the art thing. the pebble sized components cost $80.00 euro's each, however far more than the film for college projects like there's the financial factor is an important one. something that was likely not an issue for the 1st satellite designers. they're only aim was getting a satellite in the space. in october 1957, the soviet union succeeded it. sputnik one transmitted a signal back to earth. sputnik success shocked the west. air with come fit with army. those of yet on yawn, only after leaving border fundings of yet, wilson given dust baggage. now selina, it wasn't really about function. focus yet, then a sputnik all sputnik one could do was go beep beep beep. there was essentially just to show

a power as just like the race to the moon. the off designs and technology were secondary soon. the main point was who's 1st is who's the fairest of them all? he is king. i'm for him. vista, asterisk assurance, them guns in london. in response to months after sputnik, the americans launched their vanguard satellite into orbit. but the lift off was a disaster. the rock had ascended just one meter 20 off the ground. it was a bitter set back in the cold war rivalry, but then a satellite, a 2nd attempt to launch a space satellite, hours long. the u. s. is parallel explorer program, was headed by venna font brown, who had earlier worked on nazi germany's b one and b, 2 rockets. in february 1958 of the american media celebrated the explorer one becoming the country's 1st satellite to enter space for to

a dollar late. that when, if the ally ethel fall is the father of a is an anglican novel of any for the at full length events design. the subsequent decades saw the 2 superpowers pumping vast sums of money into their respective space ventures. eventually launching spy satellites to the militarization of space had begun. the americans were determined to keep the soviet union in check. and in the 1980s announced plans for a laser and satellite based protective shield against enemy missiles, nicknamed star wars. the program never took off. but the battle for space supremacy continued with a renewed focus on military applications, especially for satellites fact to the present. in february 2022,

the french city of to loose hosted the use space summit. one major point on the agenda was europe's need for a more proactive defense policy. so they can exist. they said that it is chunky push. there are now a spy satellites that can communicate with our own satellites, and it gets you and foreign powers developing technologies for shooting down objects in orbit double did is object. this is the real world now, not science fiction, suppressors and something. some of our rivals are investing heavily in peoplesoft, unknown fuel chief among those rivals is china and emerging space nation after sending a series of astronauts into orbit beginning in 2003. the country now has its own space station up and running. according to media reports, china is also planning to set up a network comprising up to 20000 satellites, bankrolled by the government. right now, the united states is still the world's biggest spender on space programs. in 2021,

they invested almost $55000000000.00, followed by europe with around $14000000000.00. china has been gaining ground with $10000000000.00. less than half of that was spent by japan and russia. both under pressure to respond. the e u plans to build up its own network of internet satellites by 2030. the estimated total cost is $6000000000.00 euros. she's extremely important is drug secured communication, and when i say secured is what is secured. in other words, using quantum technologies to have a specific quantum encryptions which will allow a to protect a government and communication. aw, be companies reasoning for defense. the european space agency is itself pushing for more urgency on both the internet satellite front and man moon landings. while you

is settling and it wasn't up to the extent, it's vital that we're part of the discussion and of chasing after holy in in thus accelerate, we need to catch up. we're accelerate in how we use space for society. and also with regard to human exploration here, human exploration, europe space strategy has based criticism. in the past, decision makers have been accused of dragging their heels and being to bureaucratic and of sleeping through the new space trend. and when was vision with the alley on the sex article, you only have to look at arianna 6, an example of collective failure across the board logging of alicia that still unable to fly and is not reusable, illustrates everything that's not working here. yeah, listening will 20th the launch of arianna 6 has been delayed several times since 2020. but the rocket has europe's hopes pinned on it and is scheduled to take off and 2023 men of criminals, which the dom start. students have been making faster progress. the university's rocket team are currently reviewing video footage of

a test flight event they attended. putting rock tiers from across germany, relished the chance to fire their contraptions up to one kilometer into the sky. o. the student version is a small test rocket powered by water pressure for got it, which is pouring the water into the tank at times and the tension mounts. according to the groups calculations, the rocket should reach a height of almost 40 meters but will the 47 winds put the brakes on their efforts . c will damage, so bottom line typically we have a successful parachute deployment fudge multiple of them, which is would you like katie here? not the rocket post flight looks really good. good with done. and then here

are data, little ones without them is not is because i'm like hitting, especially in light of the rocket size when you might think it was a failure miss effort about. but the fact that we launched that, that the principal worked and we had a successful parish deployment, which means that it was a big success, a forklift shortly afterwards. launch number 2, rocket science involves a lot of trial and error. that i oh i 009 ah, the slightest only. good. this is the sorry outcome of our 2nd fly into the tide, like the lowest section stayed intact, but the head with the electronics has been torn apart because the parachute didn't deploy properly at all. the students are now planning to switch from water pressure to solid fuel, which will deliver far more thrust. he menefee commune, sun,

business, macau medium term goal is to keep on taking part in college competitions. where teams of students compete against each other with their rocket teams getting under an medium. but in a solid feel engine is a good option. because if it's straightforward structure function and handling some open competence and the development time is shorter than an original liquid, liquid engine concept going from a physically pick. so you can focus more on the rockets other components wouldn't ducky to constantly in a new generation of space enthusiasts lou. but growing commercialization also means a changing nighttime sky. ready over $20000.00 satellites could be orbiting the earth just 10 years from now or the heavens in danger of losing their magic. oh there and like to stand him for thousands of years. the starry night time sky has inspired natural scientists to ask what those points up there actually aren't. and

he's a pull to the home there, stick to enough. there's a more profound dimension involved. where you wonder, who has the authority to intervene and say, the starry sky in itself is something worth protecting since v at us, over half of all satellites, including those belonging to starling, are located in low earth orbit or leo, up to 2000 kilometers above earth. medium earth orbit is where the gps, galileo and other navigation satellites operate. lou, you stationary orbit or geo, or television satellite circle, the planet is at 35786 kilometers lou. some operators like space x had been darkening their satellites in order to reduce their reflectance and not ruined the romance of the nighttime sky. but they continue to pose a problem for professional stargazers to honda to didn't didn't i? we have satellites that leave marks on images and can distort readings of if

a satellite is flying right by a celestial object i am currently examining. then it's a problem. i pulled one, does one much better than the does feel it? it's interest little tip. it all comes down to a fundamental question. what, what prevents satellite operators from launching no tens, but hundreds of thousands of them that tells us nothing and nobody. nissan ne month . the fact is that there are few space regulations of lee. there is the outer space treaty negotiated in 1967 by the un. it's terms govern the peaceful, exploration and use of the moon, for example, man and a ban on the deployment of weapons of mass destruction in outer space, o, ne, engaged in phase and moon exploration, and assert, and he claimed national sovereignty over the moon, less gilba. this is the province of all mankind,

but there seem to be no bounds to the commercialization of outer space. no written stipulations on who can put how many rockets satellites or people into orbit and at which altitude and no regulations on space, debris, venomously rest, shuffle, vaughn, to create law. and you need the consensus of stakeholders on van. and if it lodge number of the important party say it's not really necessary to create a law, then you have a huge problem ish problems in leesburg, as probably when he, china, russia, and the us have a manifest interest in keeping written and legal commitments to a minimum so that they can essentially do what they want. well, it is an emergency mon kernan, basi von, the i'd say gosh, wow. the only agreement that exists is that everyone does what they can to prevent collisions. but there's no agreement on any details. tigers, she enjoys justice nishaka. whoa more satellites means a growing risk of collisions. and there's the growing problem of space. debris,

garbage in space. since 1957, there have been around 6200 launches. to day space debris amounts to over 130000000 objects. many just one or 2 millimeters in diameter. together they weigh in at over $9900.00 tons and pose a major challenge. for 2 years on illegal guns, it's like to see rules like in a national park in mood. those who take their trash back home after a mission are permitted to fly. those who don't have to improve and show they will before being allowed to fly. again, it is also before the feelings of the students in darmstadt had been given the chance to send their miniature satellite into space on board. a chinese carry a rocket or launch vehicle as we get older, all of us, but they aren't sure it's politically ok to accept such help from china. owned a not true shambria. this is my lungs. we didn't want to decide this for every one . so we conducted the survey hostess. oh goodness,

it looks like 70 to 80 percent have reservations or even major reservations, hong ah, the remainder of strongly in favor of us doing the launch a food us with on possum to launch him. as yell was, i don't think any of us initially appreciated the scope of what we were getting involved. nvm hum. since that became clear, we had growing reservations, water and right now it looks like we won't go ahead with the launch. miss vanham. on the other hand, that will give them more time to focus on the european space agency competition who the earth's orbit has become a battle ground for conflicting political interests and also a new and lucrative economy. whether the various business models of the burgeoning new space sector will ultimately succeed in taking off remains written in the stars . ah, ah,

ah, jacob, a pulse with the beginning of a story that moves us and takes us along for the ride. it's all about the perspective culture information. this is dw and d, w, lead from mines do antidepressants help. their efficacy is up for debate. but the number of doctors writing prescriptions in germany is rising sharply despite the controversy surrounding the medication with how our patients being affected tablets for

depression. mm. in 75 minutes on d w. we got some hot tips for your bucket list. ah, magic corner check. hot spot for food and some great cultural memorials to boot w travel we go with this is dw news, and these are our top stories and israeli american men has been killed in a westbank shooting attack. it's a latest incident in a recent speak to violence. later on sunday, palestinian, the 40 said a palestinian man was shot dead after israeli settlers rioted.
