Hi reddit! World View is providing a new perspective of our planet and revolutionising access to space for communications technology, sensors and people. I believe that seeing the Earth from space changes the way we view humanity and our relationship with this planet; I call this ‘The Orbital Perspective’. As a NASA astronaut I travelled 71,075,867 miles in 2,842 orbits of our planet over 178 days. I flew on both the US Space Shuttle and Russian Soyuz spacecraft and logged over 27 hours in the vacuum of space during four spacewalks. I also participated in a record-setting exploration research mission held in Aquarius, the world’s only undersea laboratory and I am the author of ‘The Orbital Perspective’ – my book detailing the effects of seeing Earth from a new point of view. I’ll be talking about The Orbital Perspective and life in space at BBC Future’s World Changing Ideas Summit on 15 November in Sydney. I will be here to answer questions at 15:00pm EST, 20:00pm GMT. Ask me anything!
