Let's make this birthday one to remember.

81 years old (Born on July 09, 1943)

Happy Birthday, Colonel John Casper! You've orbited Earth more times than most of us have circled the grocery store parking lot looking for a spot. After four spaceflights, your frequent flyer miles must be astronomical—literally!

From piloting shuttles to commanding missions, you've boldly gone where few have ventured before. Retirement might mean fewer countdowns and zero-gravity snacks, but we hope you're still enjoying life's adventures with both feet firmly on the ground (most days). Here's wishing you another stellar year filled with laughter, joy, and gravity-defying fun. Keep reaching for the stars—but maybe skip re-entry this time around!
