Apollo 8 picture of Earth from the Moon
December 5, 2013
Guess I'm showing my age, but the picture that most changed my life, as I hope it did for most of the world, was the picture sent back from the moon by the astronauts of Apollo 8, that first showed us the Earth as one world with no visible borders, floating alone in the blackness of space. Suddenly the world didn't seem so big and important in the overall scheme of things.
In 2016, The Planetary Society’s LightSail program will take the technology a step further.
