XKCD: Space Launch System and Wernher von Braun

This comic from XKCD is especially appropriate given my earlier post on Tom Lehrer. One of Lehrer's most famous songs is a satirical savaging Wernher von Braun, the Nazi rocket scientist who developed the Saturn V rocket for the US after World War II. Here is Lehrer's song:

"Once the rockets are up, who cares where they come down?
That's not my department," says Wernher von Braun.
