Army Lt. Col. Shane Kimbrough (MS in OR from Georgia Tech) is an astronaut in the International Space Station.
Kimbrough … completed a space walk of six hours and 45 minutes Thursday afternoon. [His] tasks included the relocation of two crew and equipment translation aid carts, the lubrication of the Canadarm2 end effector, along with cleaning and lubrication of the starboard solar alpha rotary joint.
I always wanted to be an astronaut, so I am totally envious. Maybe OR can go for a moonwalk next.
