The last man on the moon has died of old age

Eugene Cernan has died, age 82. In December of 1972, as commander of Apollo 17, Cernan was the last person to leave a footprint on the moon as he was the last man to step back into the lunar module. Consider that: someone born just after Cernan stood on the moon would now be well along in his or her career. And if this hypothetical person joined the NASA astronaut corps in order to go to the moon, *that* person is now pushing age limits. And by the time NASA *might* get back to the moon in the mid to late 2020’s, that person would be well into their fifties.
