40 years ago today, astronauts Armstrong, Aldrin and Collins were on their way to the Moon.

AS11-36-5355 (17 July 1969) — Most of Africa and portions of Europe and Asia can be seen in this spectacular photograph taken from the Apollo 11 spacecraft during its trans-lunar coast toward the moon. Apollo 11, with astronauts Neil A. Armstrong, commander; Michael Collins, command module pilot; and Edwin E. Aldrin Jr., lunar module pilot, onboard was already 98,000 nautical miles from Earth when this picture was made. While astronauts Armstrong and Aldrin descended in the Lunar Module (LM) “Eagle” to explore the Sea of Tranquility region of the moon, astronaut Collins remained with the Command and Service Modules (CSM) “Columbia” in lunar orbit.
