Question: What unique artifact did astronaut Charles Duke leave on the moon in 1972?
Answer: NASA’s Charles Duke left a family photo of himself, his wife, and his two sons on the moon’s surface, where it remains to this day. The family photograph had a message written on the back, “This is the family of astronaut Charlie Duke from planet Earth who landed on the moon on April 20, 1972.” Because the temperature of the moon goes up to 400 degrees in the area Duke landed, he says it’s probably faded by now.
