Let's make this birthday one to remember.

68 years old (Born on March 30, 1957)

Happy Birthday to the incredible Yelena Kondakova—one of the bravest explorers who's ever left Earth's atmosphere and decided that floating endlessly in space was her idea of a "long vacation." Your groundbreaking flight aboard Soyuz TM-20 back in '94-'95 proved beyond doubt you're comfortable spending months where most people would give up after two hours without Wi-Fi.

Thanks also for taking NASA's Space Shuttle Atlantis by storm in 1997, proving once again that Russians and Americans get along fine—as long as we stick to orbital altitudes. Keep inspiring us all with your stellar adventures—we hope this year launches you into orbit-worthy happiness!
