From the breathtaking impression of footsteps on the lunar soil to the dazzling arc of the earth from the moon’s horizon, NASA’s Apollo program has produced iconic images for the world to cherish. Now, Apollo 16 astronaut Charles Duke has made a fascinating revelation about his moon landing. When Duke took his first steps on the surface of the moon on April 20, 1972, he left a picture of his family – his wife, two sons and himself, with a written message, and it remains to be seen on the natural satellite.
The message, “This is the family of astronaut Charlie Duke from planet Earth who landed on the moon on April 20, 1972,” echoes the “human side of space exploration,” Duke told Business Insider. “I’d always planned to leave it on the moon, so when I dropped it, it was just to show the kids that I really did leave it on the moon.”
