Arthur C. Clarke: Transit of Earth
“Transit of Earth” is a science fiction short story by Arthur C. Clarke, published in January 1971 in Playboy magazine. Evans is an astronaut stranded on Mars who knows he has less than twenty-four hours of oxygen left. As he waits to record an astronomical phenomenon that occurs only once every hundred years—the passage of Earth across the face of the Sun as seen from Mars—he reflects on his life, his fears, and the memories that haunt him. With the calm of someone who has already accepted his fate, Evans prepares to carry out the mission for which his companions sacrificed their own lives.
