Let's make this birthday one to remember.

79 years old (Born on June 20, 1945)

Happy Birthday, Colonel Buchli! You've soared through space four times—clearly proving that gravity just couldn't hold you back. Your stellar adventures have inspired countless dreamers to reach for the stars (and made us all a bit jealous of your frequent flyer miles).

Even though you've retired from orbiting Earth, your legacy continues to shine brighter than ever. May this birthday be filled with laughter and joy that's truly out-of-this-world—and may every candle on your cake remind you how many successful missions you've completed around the sun.

Here's wishing our favorite astronaut-Marine another year full of cosmic achievements!
