but 1st this edition of the arianne 6 rocket has to prove itself. the launch is planned for late 2020. the universe is suffused with particles that traverse entire planets stars and galaxies neutrinos there among the most common elementary particles and a source of fascination for scientists in the antarctic an entire observatory has been built to detect these mysterious objects. in 2015 to physicists shared the nobel prize for demonstrating that neutrinos have mess but how much mass to find out researchers have developed the world's most precise scale. tree knows are born during nuclear fusion in the sun countless numbers of solar neutrinos arrive on earth every 2nd and that's just one source of this mysterious particles they're so puny that until recently scientists believe they had no mass at all. today we know that this subatomic particles do have a mass an extremely small one physicist magnus lesser is involved in experiments to pin it down they've already yielded initial results. yet so these measurements allowed us to narrow down. the estimat

but booster rockets will provide arianne with the necessary thrust. at this advanced production facility the boosters structural casings are constructed out of lightweight carbon fiber materials and other rockets the casings are still made of metal. the boosters have to withstand enormous strain they're filled with solid propellant fuel when it's ignited it will produce tremendous heat and pressure in the interior. ariane 6 has yet to be launched but engineers are already working on improving it they want to reduce its weight to increase its thrust. so the plan is to develop a new upper stage by 2025. we call it a black about stage because it will be. a stage and as you know cow bunnies they're never made taller and this is why huge willow is to have up to 2 tons mock up ability for customers. it currently takes about a year and a half to build an engine like this by using 3 d. printing production time could well be slashed to just a few weeks and the costs reduced by a factor of 10. in 2018 a printed prototype of the engine was tested at the german a

arianne 6 and for the 1st time these components sprayed on by overbought. so much it's emitted like this creates a uniform surface which is important for the structures on the upper section. because it's much better and easier if you have much better control of the process if it's and it's much more cost effective than the previous method would have said there are $2.00 versions planned for the new rocket one will be able to launch 2 satellites and the other will be able to launch for the operators hope this flexibility will help to attract more customers. that calling for e.u. funds for rockets to go to european produces. because in z.f. you mean we're much more dependent on the commercial market it's just a question of fairness even if we have institutional launches and europe we should launch with the european rocket. up to 12 rocket said to be produced annually double the previous amount. this fuel tank will soon take off on its maiden flight . the 1st carry on 6 will launch from french briana at the end of 2020. 30 children these days time spent in sch
