A veteran of four Apollo missions, Thor ran telemetry and the reaction control thrusters for the Lunar Excursion Module. A consummate prankster, Thor would pretend he was the voice of Mission Control and instruct the astronauts to do emergency calisthenics every few hours. On several occasions Thor replaced Buzz Aldrin's Tang powder with lunar dust (Buzz never noticed). These days Thor is retired in Boca and stays busy restoring his '48 Studebaker.
