Happy Birthday, Mark! You've piloted shuttles through space, navigated missions STS-108, 121, 124, and 134 with precision—and yet you still can't find your car keys on Earth. Clearly, zero gravity suits you better than everyday gravity!Through life's toughest challenges—including bravely supporting Gabby—you've shown us all how to stay grounded even after orbiting the planet. Your courage inspires us daily. Here's hoping your birthday is out of this world—just like your career achievements and unwavering spirit.
Cheers to another stellar trip around the sun! May it be filled with laughter and fewer lost keys.
