87 years old (Born on December 23, 1937)
Happy Birthday, Karol Bobko! You've boldly gone where few have ventured—piloting the iconic Space Shuttle Challenger on its triumphant 1983 mission and steering Discovery safely through space in 1985. Not to mention your historic role aboard Atlantis for a top-secret Department of Defense adventure; we assume you saved Earth from aliens at least once!From pioneering cooperation during the Apollo–Soyuz Test Project back in '75, you've truly been an interstellar diplomat (and probably earned enough frequent flyer miles for a lifetime). Here's wishing you another orbit around the sun filled with laughter, joy—and gravity firmly beneath your feet!
