Let's make this birthday one to remember.

60 years old (Born on October 30, 1964)

Happy Birthday, Sandra! From floating gracefully aboard the International Space Station during Expedition 18 to mastering zero-gravity hairdos that defy physics itself—you've truly set astronomical standards. Your ability to juggle complex experiments while orbiting Earth at thousands of miles per hour still leaves us mere mortals amazed (and slightly dizzy).

Here's wishing you another stellar year filled with adventures as exciting as your spacewalks and successes even more impressive than docking spacecraft in record time. May gravity never hold down your dreams or dampen your cosmic sense of humor—after all, you're out-of-this-world awesome! Keep soaring high, astronaut extraordinaire!
