  • Peter Bond


October 7, 1959, marked a new era in the history of humanity. On that day, 29 fuzzy black-and-white images trickled back to Earth from a Soviet spacecraft that had successfully looped around the Moon, venturing some 400,000 km (250,000 mi) from Earth. After staring at the wonders of the night sky for millions of years, technology had enabled human eyes to see an uncharted, extraterrestrial terrain—the far side of the Moon.
