Let's make this birthday one to remember.

91 years old (Born on August 17, 1933)

Happy birthday, Gene Kranz! You've officially orbited the sun once more without a "problem," Houston. Your calm leadership during Apollo 13 had us all holding our breath; who else could keep smiling through spacecraft malfunctions? We can't help but still quote your iconic words—after all these years, failure is STILL not an option!

Your white vest might be legendary at mission control, but today we imagine you trading it for a party hat and enjoying cake instead of calculations. Here's wishing the man behind so many successful missions another year filled with joy that’s truly out of this world!
