Saturn V was, at the time of construction, Nasa's mightiest launch vehicle: a 110-meter rocket with five F-1 engines in its first stage alone. Saturn V launched several missions from Earth.
It was launched again from the Kennedy Space Center on 16 July 1969. The Tenth Doctor watched this launch from the ground. He described it as "packing three men into a tin can filled with a skyscraper's worth of fuel, hurling them out of the atmosphere into the harshest conditions imaginable, with nothing more powerful than a pocket calculator to guide them. For what? Just because you can." (PROSE: Blue Moon)
