I had the pleasure this evening of meeting Mark Lee, retired USAF Colonel and former NASA Astronaut.  Colonel Lee, a veteran of four Space Shuttle missions, presented an overview of the US space program and his astronaut career for my local chapter of the American Society of Civil Engineers.

Colonel Lee’s space resume includes such feats as the launch of the Magellan Venus probe, repair of the Hubble Space Telescope, and he and his wife N. Jan Davis became the first married couple in space.  Of particular interest to me, though, was his untethered EVAs and jetpack flights.  Exciting stuff, whether on Mars or 250 miles over our heads.
