    On Aug. 23, 1966, humanity welcomed its first view of Earth taken by a spacecraft from the vicinity of the Moon. The photo was transmitted to Earth by NASA’s unmanned Lunar Orbiter I — a robotic surveyor sent into orbit to map possible lunar landing sites years before the Apollo program — and was received at a NASA tracking station near Madrid, Spain. In celebration of the 45th anniversary of the landmark transmission, LIFE.com presents other remarkable, moving, humbling photos of our lonely blue and green planet taken from the depths of space.

    Out of this world, literally: Earth Seen From Space
