Let's make this birthday one to remember.

72 years old (Born on October 13, 1952)

Happy Birthday, Michael! To a man who's logged over 3,400 hours soaring through the skies and spent more than half a day casually strolling in space—your frequent flyer miles must be astronomical. Whether aboard Discovery, Endeavour or Atlantis, you've always known how to make an entrance (and exit) that's truly out of this world.

Here's wishing you another year filled with adventures that defy gravity—and birthday cake slices as big as your legendary achievements. May your celebrations today rival the thrill of floating freely above Earth...but hopefully without needing any spacesuit repairs mid-party!

Cheers to you, astronaut extraordinaire!
