“I knew I was alone in a way that no earthling has ever been before.” -Michael Collins
Less than a decade after the first human was launched into space, astronauts Neil Armstrong, Buzz Aldrin and Michael Collins journeyed from the Earth to the Moon. For the first time, human beings descended down to the lunar surface, opened the hatch, and walked outside. Humanity had departed Earth and set foot onto another world.
While Armstrong and Aldrin walked on the surface, collecting now-iconic photos, deploying science instruments and returning hundreds of pounds of lunar samples, Michael Collins orbited overhead, embarking on a missing that no human being had undertaken before. Forty-seven years later, humanity has never had a bigger breakthrough as far as crewed space exploration goes.
