Let's make this birthday one to remember.

91 years old (Born on October 22, 1933)

Happy Birthday, Donald H. Peterson! You've always been ahead of your time—literally orbiting above us mere earthlings. From pioneering the Manned Orbiting Laboratory program in the 1960s to boldly stepping aboard Challenger's debut flight in '83, you've truly shown gravity who's boss.

Your stellar adventures continue to inspire generations who dream big and look skyward. Here's hoping your birthday is out-of-this-world fantastic—filled with laughter, cake (hopefully easier to eat than astronaut food), and zero-gravity dance moves that defy age as effortlessly as you once defied Earth's pull!

Keep soaring high; you're forever our favorite space pioneer!
