83 years old (Born on June 20, 1941)
Happy Birthday, Ulf Merbold! You've always been ahead of your time—literally soaring above the rest. As the first West German astronaut—and only second from Germany to venture into space—you truly set astronomical standards for those who followed (and gravity-defying hairstyles too!). Your missions aboard Spacelab made us Earthlings proud and taught everyone that there's no limit... well, except perhaps oxygen tanks!Even though you're back on solid ground now, recent generations still look up to you—in every sense. Wishing a stellar birthday filled with cosmic cake, zero-gravity laughter, and plenty of interstellar adventures yet to come!
