Happy Birthday, Steven! You're truly out of this world—literally. After four spaceflights and more than 40 days floating around in zero gravity, you've defied physics so many times we're starting to suspect it's personal between you and gravity!Your stellar engineering achievements at NASA are famous enough to make aliens jealous. But seriously, how do astronauts even blow out birthday candles? Whatever your method may be: we hope today is filled with laughter on Earth, since clearly nothing can top the ultimate party trick—you orbiting our planet multiple times aboard a spacecraft!
Wishing you endless happiness (and solid ground) today!
