“The sheer beauty of it just brought tears to my eyes.
“If people can see Earth from up here, see it without those borders, see it without any differences in race or religion, they would have a completely different perspective. Because when you see it from that angle, you cannot think of your home or your country. All you can see is one Earth....”Other quotes, and the full story, can be found here, at Mankind's rarest view: Earth from afar.
