Let's make this birthday one to remember.

75 years old (Born on April 09, 1950)

Happy Birthday, Kenneth! You've piloted shuttles through space five times—clearly, parallel parking on Earth must be a breeze for you. After all those missions and zero-gravity flips, we hope your birthday cake stays firmly grounded (and doesn't float away).

From commanding spacecraft to leading crews among the stars, you've truly set the bar astronomically high. May this year bring you as much excitement and success as your stellar career has given us inspiration—and may gravity always cooperate when you're blowing out candles. Here's to another orbit around the sun filled with laughter and adventure—happy birthday!
