Rockets have taken animals into space to prepare for the day when man himself will make the trip. But this woman thinks the way we should be getting there is balloons. If you're going to do something really different you cannot have the word 'impossible' in your vernacular. And some people might have thought it was impossible for a balloon to safely transport things into space and back. Things like research tools, chicken burgers and a Google executive. But they were all made possible here in Tucson, Arizona at the World View headquarters. So what's really kind of awesome about ballooning technology, it is so completely different to the way people have thought about accessing space before. There's no noise, it's completely silent and you're using gravity. So what we've done is created this vehicle that can stay continuously over a location. How we do that is the magic. The "magic" starts with a Stratollite, a giant balloon filled with a gas like helium which helps it float upwards. Below that are smaller balloons filled with air which act as a ballast. If there's more air inside them they get heavier and the Stratollite sinks down, if there's less air the craft is lighter and moves up. All of this allows the Stratollite to sail the winds of the stratosphere and unlike traditional satellites, hold its position for days or even months at a time. We have launch, all the instruments, the landing, all in the same vehicle. That's completely revolutionary. And we can fly just about any instrument on it, whether it's communications, weather instrumentation cameras any kind of device you can imagine. So in the years to come, we're imagining that we can help millions, let's think big, billions of people get online who currently can't be online. We envision being able to transform the way we work with hurricanes and other severe storms, so that we can actually get much better warnings of what's happening with these storms than we currently have now so that people can get out of the way. And then we can even help the first responders with communications and eyes in the sky and do this all around the world. Poynter's space ambitions began with an earthbound adventure, Biosphere 2. Living for two years and 20 minutes with seven other people inside a sealed-off dome, designed to simulate life in a space colony. One of the seminal experiences was being viscerally part of my biosphere, in a very literal way. So we drank the same water over and over again. We breathed the same oxygen over and over again. So we were very literally part of our biosphere. That gave us this incredibly powerful perspective of the planet that we live on. It's very akin to the kind of experiences that astronauts have when they see the Earth from the blackness of space. We wanted to find a way to really give that to ourselves but also to everybody else. So while governments and companies are using Stratollites to launch remote sensors and cameras into the stratosphere, Poynter's ultimate goal is to send us all out there too. If we can take people to space I think it's going to change many people's idea about this planet that we live on. The idea that we are all on this same planet together, and then what are people going to do with that experience? In my mind, that's the important part. Coming back from space and taking that experience and doing something great with it. Wow! How awesome that would be to be able to make that change in the world.
