You cannot look up at the night sky on the Planet Earth and not wonder what it’s like to be up there amongst the stars. And I always look up at the moon and see it as the single most romantic place within the cosmos.-Tom Hanks

I see Earth! It is so beautiful!-Yuri Gagarin

Mining asteroids will ultimately benefit humanity on and off the Earth in a multitude of ways.-Peter Diamandis
