Happy Birthday, Michael D. Griffin! You've orbited the sun once again—no small feat for someone who's spent a career launching things into space rather than circling around it. From leading NASA through stellar missions to steering Johns Hopkins University's Space Department toward astronomical success, your contributions have truly been out of this world.May your birthday be filled with laughter brighter than rocket flames and cake tastier than astronaut ice cream (though admittedly that's not too difficult). Here's hoping you continue defying gravity—and age—with grace and humor. After all, when you're as accomplished as you are, every year is just another successful mission completed!
