Happy birthday, Aleksandr Kaleri! You've certainly mastered the art of hovering around without gravity getting you down. They're still finding your snacks floating happily aboard the ISS—rumor is even cosmic dust takes notes from you on staying in orbit this impressively!From space stations to record-breaking missions, you've chauffeured Earth through over 769 days among the stars (second-longest time anyone has managed!). Yet each return home hasn't slowed your boundless energy or stellar wit. May your birthday cake stay firmly earthbound today—and may there always be plenty of funny stories left untold for celebrating down here. Cheers!
