Let's make this birthday one to remember.

73 years old (Born on January 26, 1952)

Happy Birthday, Mario Runco Jr.! You've orbited Earth more times than most of us have circled the grocery store parking lot looking for a spot. From your stellar adventures aboard Atlantis in 1991 to Endeavour's missions in '93 and '96, you've truly taken "going above and beyond" to astronomical heights.

Whether floating effortlessly through space or navigating complex physics equations back on Earth, you’ve shown that gravity is just another challenge you're happy to overcome. Here's hoping your birthday celebration is out-of-this-world—though perhaps with fewer freeze-dried meals this time around!

Cheers to many more cosmic journeys around the sun!
