This stunning photograph of Earth was taken from an altitude of 18,000 kilometers (11,185 miles), by an automatic camera aboard Apollo 4. Antarctica appears at the top of the crescent, with the northwest coast of Africa visible at the bottom.
Apollo 4 was the first uncrewed test flight of the Saturn V launch vehicle, the type used by the U.S. Apollo program to send the first astronauts to the Moon.
