IT IS called the “Blue Marble”. The image of Earth, reduced to a child’s toy suspended in the blackness of space. It was Christmas Eve in 1968 when the people of the world first caught a glimpse of their small place in the universe. Apollo 8 had entered lunar orbit and that evening the three astronauts featured in a live television broadcast showing images of our blue planet.
