Let's make this birthday one to remember.

61 years old (Born on February 21, 1964)

Happy Birthday, Mark! You've orbited Earth, piloted space shuttles, and even commanded the International Space Station—clearly, blowing out candles should be a breeze for you. Your incredible journey from engineer to astronaut has inspired countless dreamers to reach for the stars (literally!).

Recently transitioning from exploring galaxies to navigating politics as a U.S. Senator, you've proven that rocket science might actually be simpler than Capitol Hill debates. Here's hoping your birthday is filled with laughter and joy—after all those zero-gravity flips and spacewalks, you deserve some down-to-earth fun today. Keep soaring high; you're truly out of this world!
