Let's make this birthday one to remember.

76 years old (Born on November 08, 1948)

Happy Birthday, Dale! You're truly out of this world—literally. From floating aboard Challenger during mission STS-8 in 1983, to gracefully maneuvering in zero-gravity, you've set the bar astronomically high for birthday celebrations. Rumor has it cake tastes sweeter when enjoyed aboard a spaceship; unfortunately, gravity makes candles difficult.

Your courage and adventures continue to inspire generations of dreamers and stargazers who wonder if orbiting the Earth qualifies you as having fewer birthdays due to relativity—we'll let NASA verify that one. Today we celebrate someone whose achievements are timeless and whose age remains a closely guarded NASA secret. Enjoy!
