Happy Birthday, Robert! You've always been out-of-this-world—literally. From defying gravity aboard Shuttle missions STS-29 and STS-38, you've inspired us all to reach for the stars (or at least the cake). Rumor has it you were top-notch at navigating through shuttle procedures; surely finding your way around a birthday celebration should be easier...right?Here's wishing that your day is filled with fewer checklists than astronaut training but just as much adventure and excitement. Keep exploring new frontiers—even if they're now mostly in gardening or golfing—and may this trip around the sun be your most stellar one yet!
