People walking on the moon?

The last person to walk on the moon was Eugene Cernan, commander of Apollo 17.  He and Harrison Schmidt, the first astronaut who was also a scientist, landed on the moon on December 11, 1972, and left on December 14th.  Unless someone has gone to the moon without us knowing about it, it has been 36 years since anyone has walked on the moon.  For how many students is a discussion of walking on the moon a history lesson rather than a science lesson?

I bring this up, in part because of the pieces I have posted on the crisis in science and math and because of the following cartoon, which I obtained in 1986 (March 2nd, if I am not mistaken).
