Happy Birthday, Steven Lindsey! From commanding Discovery's final voyage to steering NASA's astronaut office with stellar precision, you've always been a master at navigating tight spaces—whether it's orbiting Earth or managing astronauts' egos. Your leadership has truly been out of this world!As you celebrate another trip around the sun, remember: age is just a number—but in your case, it might also be an orbital altitude. Keep inspiring us all with your gravity-defying achievements and cosmic sense of humor. Here's wishing you many more successful missions ahead (and fewer zero-gravity birthday cakes floating away). Happy Birthday!
