Let's make this birthday one to remember.

79 years old (Born on March 28, 1946)

Happy birthday, Wubbo! To the man who boldly went where no Dutchman had gone before—space—and returned to Earth with gravity-defying stories and a smile brighter than any star. Your cosmic adventures aboard Challenger made history, inspiring generations of dreamers back home.

And let's not forget your stellar contributions at Delft University of Technology; you've guided countless students through physics puzzles tougher than rocket science itself. May your day be filled with laughter lighter than zero-gravity antics and cake tastier than astronaut ice cream. Here's wishing you another orbit around the sun full of discoveries as brilliant as you are!
