Let's make this birthday one to remember.

73 years old (Born on January 24, 1952)

Happy Birthday, William Readdy! From piloting the incredible STS-51 mission to commanding the unforgettable STS-79, you've truly taken birthday celebrations to astronomical heights. Rumor has it NASA still uses your shuttle maneuvers as examples of "how it's done," and astronauts everywhere secretly wish they could orbit Earth with half your style.

Even though gravity might be catching up a bit these days, we know you're still soaring high in spirit. May this year bring you plenty of laughter, zero turbulence, and cake slices bigger than any payload you've ever delivered. Keep reaching for the stars—just don't forget your party hat!
