The last time a person walked on another world.
As Eugene Cernan left the moon, he said
"As I take man's last step from the surface, back home for some time to come - but we believe not too long into the future — I'd like to just [say] what I believe history will record. That America's challenge of today has forged man's destiny of tomorrow. And, as we leave the Moon at Taurus-Littrow, we leave as we came and, God willing, as we shall return, with peace and hope for all mankind. Godspeed the crew of Apollo 17."
