Let's make this birthday one to remember.

72 years old (Born on May 06, 1952)

Happy birthday, Chiaki Mukai! You're truly out of this world—literally. As the first Japanese woman to float gracefully through space (twice!), you've shown us all that gravity is overrated and breaking barriers can be a stellar experience.

From pioneering medical research in orbit to inspiring countless young dreamers back on Earth, your achievements continue to shine brighter than any star. May your special day be filled with laughter, joy—and perhaps fewer freeze-dried meals!

Here's wishing you another year full of cosmic adventures and earthly delights—you've earned it by boldly going where few have gone before. Happy Birthday!
