About Karl

When NASA classified Karl as non-astronaut material he walked into ABC Radio station Double J and offered to talk about the Space shuttle launch instead.  They said ‘Okay’ and his radio career took off like a rocket. ‘Great Moments In Science’ ran on Double J from 1981, while Karl moonlighted as a medical student.

Since then, his media career has exploded to include TV, books, newspapers, magazines, scripting, professional speaking, and of course, the Net.
