Scouting Magazine reports that two-thirds of pilots and scientists selected as astronauts have been Boy Scouts.
Of the 312 astronauts, at least 207 have been identified as having been Scouts or active in Scouting. That list includes 39 Eagle Scouts, 25 Life Scouts, 14 Star Scouts, 26 First Class Scouts, 17 Second Class Scouts, 13 Tenderfoot Scouts, three Explorers, 25 Cub Scouts, 10 Webelos Scouts, one King’s Scout, two Wolf Scouts and 32 with unknown ranks, including 27 who were Girl Scouts.
Half of the 135 space shuttle missions included at least one Eagle Scout. That number doesn’t include Eagle Scouts who took trips to the International Space Station aboard Russian Soyuz rockets. The most recent example was Eagle Scout Thomas H. Marshburn, one of three crew members on the 145-day Soyuz TMA-07M mission, which returned to Earth on May 14, 2013.
