exploration to our future life this is a footprint of neil armstrong the astronaut who first landed on the moon in 1969 the u.s president nixon welcomed him and two other april 11 astronauts after they were safely back on earth nasa even coordinates them for about three weeks in case they brought back sun moon genes just like what we do for international travel during covington pandemic it has been over 50 years since a giant leap for mankind on the moon what have we achieved for the past half century is the space technology stuck on the plateau of slow growth the answer is definitely no we are still hovering the dreams of escaping the life on earth for the mystery of space from april 11 to 17 12 astronauts have been working on the moon however we only have one who stayed on the moon forever that person is dr schumacher the expert who devoted himself to astro geology do you still believe that new landing is still far away from us there's a more convenient way space funeral is becoming more and more popular which allows regular people just like you and me to fulfill the widest dream of working among stars at the end of our life journey i would like to give you a couple seconds could you tell me what these cubes are there's a custom ash capsule that contains the cremated remain samples after collecting the samples from the customer the startup edison will launch the spacecraft from the vandenberg air force base in california this fantastic event will be webcasted moreover friends and relatives are welcome to join the launch viewing and celebrate while the rockets reach into the final frontier for about two years families and friends will be able to follow the journey by mobile app enhancing the personal connections and experience at the last poetic moment the spacecraft will harmlessly re-enter into the earth's atmosphere blazing as a shooting star besides the space funeral space mining is another attractive application with long been considered as the science fiction governments are now implementing programs and legislations for space mining besides the pioneer deep space industries many companies such as orange space are funded to pursue the asteroid mining with the goal of developing technologies for prospecting and eventually extracting space resources currently two types of the resources are easily available the number one is the near-earth data joint for example the expert calculates an asteroid named 241 germania can possess 95 children u.s dollar in mineral wheels larger than the gdp of the all the countries in the world though it is still far away but should be within reach in the next century how realistic is the trillion dollars estimation and how much will it cost to mine from millions of miles away it is a long way to improve the estimation accuracy and cost control although we still have lots of the challenges ahead of us once all of them are addressed it gives the opportunity to rewrite the current industry power grid and the old order on earth another easy to have resource is luna we all know that we have plenty of the silicon iron and rare earth elements on the moon one of the most exciting discoveries we have so far is the water or hydroxide as the lunar pole in the form of permafrost or ice with the hydroxide existing we could easily have oxygen and hydrogen for long-term living on the moon moon could be the base or springboard for the future deep space explorations all these above are the niche applications for aerospace which commercial values still need to be proven in the coming future the application with the most potential to impact our daily life are commercial satellite and main flight it is unbelievable that we still have 3 billion people that cannot access to the internet even some regions of developed countries it is difficult slow and expensive many companies are trying to address these challenges google and facebook are the pioneers try to addressing these challenges enormous balloons or the solar power zones however all these ambitious high attitude flight campaign field until spacex launched starlink in 2015. starting is a satellite internet constellation with thousands of the satellite circuit in the low earth orbit working in combination with the ground transceivers satellite internet technology has been around for decades spacex improved the technology in two notable ways firstly the satellite circle around the earth at around 300 miles above the surface the shortened distance will drastically improve the internet speed while reducing latency secondly over 40 000 satellites will be launching to the orbit to ensure the global coverage without any service drop house it is a crazy number if we consider that currently only 4 000 satellites are active in the sky falcon 9 the rockets with underlying technology can make this a reality with the satellites that stack as a box of the chips the rockets could easily deploy 60 satellites into the orbit every time starlink started the public better service last october spacex plans on bumping up the down low speed to 300 mega feet per second with a 20 milliseconds latency indeed the satellite constellation cannot replace the traditional broadband network however the huge advantages of the space x starlink will appear especially in long distance communications for example from new york to london the 4600 kilometers hibernia express cable is often capable with a forced speed compared with the second versus atlantic crossing one cable six milliseconds is saved nowadays thousands of transactional could happen within one millisecond if the fed announces a 200 basis point reduction of the federal run rate imagine the time from new york to royal exchange were shortened from 65 milliseconds to 43 milliseconds how many financial organizations and individuals were pay for this infrastructure besides satellite constellation space tourism is another increasing hot topic with more and more vehicles such as the starship beam development space tourism will be a reality in the coming future gateway foundation a u.s company that founded by the former nasa engineers just announced that they will build the first space hotel to accommodate 100 tourists every week since 2027. this hotel will also offer a range of the holiday accommodation options the guests will be able to relax in a bar with a further feature that seems like to defy the physical laws when enjoying the most beautiful sunrise over the earth with such a hotel going to a space will just be an option for people to pick for their vacations just like going on cruise or going to disneyland all these sounds perfect how to ensure these initiatives successful with the development of the technologies and regulations we still need two prerequisite conditions on the one hand we need a safe space environment currently over 20 thousand debris flow in the earth's orbit most of them are centralized in the low earth orbit it is the risk and challenges for the future satellite deployment and the space explorations on the other hand we need a safe and comfortable vehicle spacex experienced tons of the failures before they successfully launched the falcon 9 and starship however they claim that they become more and more confident with the data that collected after each launch each remarkable milestone is the result of series of concepts design and test i'm now working at an eye one of the leading companies collaborating with nasa and spacex to usher in the new era of aerospace the approach to test is the strategic asset to the business which can help to ensure the qualification and reliability of the critical missions from the hardware in the loop to qualification testing from launch operation to monitoring the payload in real time we offer full cycle solutions and two chains to make this successful we salute all the individuals that make these incredible fees possible and look forward to enabling future critical missions around the world it is now the golden era for aerospace a industry with high investment and long return cycle however space alludes to every one of us where do human comes from where are we headed we are the force to make the way to start going do not just be a bystander join and to be a change maker purpose one day in the future when you look up into the sky and reflecting one of your past beloved or the meaning of life what will pop up in your mind mrs caroline the wife of dr maker shared her feeling after husband passed away she said i miss him always but to this day i can look up at the moon imagine him and his rockets there looking down at me he sterilized every single one of my nice guys thank you [Applause]
