"The vast loneliness up here of the Moon is awe-inspiring, and it makes you realize just what you have back there on Earth. The Earth from here is a grand oasis to the big vastness of space." — Apollo 8 astronaut Jim Lovell
From NASA: Fifty years ago today, this iconic "Earthrise" photo was taken aboard Apollo 8 by Bill Anders. Before humanity ventured to the Moon, our view of our home planet consisted of what we could see from horizon to horizon. It was not until this stunning photo (along with many others) came back to Earth with the three Apollo 8 astronauts in December 1968 that we saw Earth as a vibrant, delicate, blue and white globe framed by the velvety blackness of space. This iconic picture shows Earth peeking out from beyond the lunar surface as the first crewed spacecraft circumnavigated the Moon.
When I see that pic I am always reminded of the tv series Big Blue Marble and its song – The world's a big blue marble when you see it from out there….
