Let's make this birthday one to remember.

66 years old (Born on August 18, 1958)

Happy Birthday, Sergei Treshchov! Wishing a stellar celebration to the cosmonaut whose adventures aboard Expedition 5 made floating around in microgravity look easy. Your impressive contributions at the International Space Station truly elevated how we earthlings think about space exploration—plus, rumor has it your zero-gravity flips still hold an unofficial ISS record!

Even though gravity insists on keeping you grounded down here today, may your spirits soar beyond orbital altitudes. After all those laps around Earth (and mastering toothpaste squeezing in orbit), relaxing safely on solid ground must seem oddly luxurious! Cheers to another cosmic journey called life; here's hoping this year's mission is filled with astronomical success—and plenty of cake not served from tubes!
