Happy birthday, Kathryn! Who knew that soaring through space twice and contributing to building the International Space Station could be easier than blowing out all those candles? We hope this year's celebration is even more gravity-defying than floating in orbit as you exchange party treats for astronaut food—although, let's face it, nothing beats birthday cake on Earth!Your incredible work aboard the ISS continues to inspire us—proving some heroes really do wear spacesuits. May your stellar career always remind us that you're never too old or too accomplished to keep aiming high. Here's to more out-of-this-world adventures ahead!
