Let's make this birthday one to remember.

55 years old (Born on May 25, 1969)

Happy Birthday, Dmitri! Wishing you an astronomical celebration that's truly out of this world—though after Expedition 26/27 aboard the International Space Station, you've probably had enough zero-gravity cake to last a lifetime. May your day be filled with laughter brighter than orbital sunrises and joy more enduring than space station duct tape.

Your incredible journey among the stars continues to inspire us all back here on Earth. Here's hoping your next orbit around the sun brings even greater adventures (and fewer floating crumbs). Keep reaching for those cosmic heights—but today, enjoy some gravity-bound fun. Happy birthday, cosmonaut Kondratyev!
