Happy Birthday, William Shepherd! You commanded Expedition 1 aboard the International Space Station, boldly going where few had gone before—while making floating toothpaste and orbital haircuts look easy. Not everyone can casually claim they were one of space’s original roommates; here's to your incredible pioneering spirit!Wishing you another gravity-defying year filled with joy and laughter back on Earth. May your celebration reach astronomical proportions without requiring Mission Control approval! Thanks for leading humanity's first crewed journey aboard ISS—you’ve forever earned cosmic bragging rights. Enjoy being a star traveler who never ages…or at least experiences fewer birthdays due to relativity!
