Today it’s the Curiosity probing Mars. Back when I was a kid, it was the Pioneer spacecrafts blasting into outer space.
Just in case one of the Pioneers was intercepted by aliens(!), a metal plaque was included depicting humankind in the form of a naked man and woman.
ALIEN #1: Hot bodies, but I wonder why they don’t wear clothes.
ALIEN #2: Looks like a dull planet—Nothing but Caucasians.
There was tons of news coverage about the plaque, and after all these years I’d like to thank NASA for providing me and zillions of other horny youngsters a thrilling chance to gaze at nude bodies.
Of course a new plaque would have to be updated.
