This iconic image speaks volumes. To many it underscores the vastness of space, the loneliness of the cosmos and how fragile our home planet really is. Entitled “Earthrise,” it was taken by astronaut William Anders during an orbit of the moon as part of the Apollo 8 mission. Apollo 8 was the first manned mission to the moon, which entered the Moon’s orbit on Christmas Eve 1968. That evening, the astronauts onboard held a live broadcast, in which they showed pictures of the Earth and moon as seen from their spacecraft. Command Module Pilot Jim Lovell said, "The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth." The astronauts ended the broadcast with the crew taking turns reading from the book of Genesis.
