Let's make this birthday one to remember.

75 years old (Born on January 28, 1950)

Happy Birthday, David! If life is measured in space miles, you've circled the planet enough times to qualify for NASA’s "Frequent Orbiter" rewards program. Four missions and countless engineering feats—you're truly an out-of-this-world explorer (who humorously never lost a wrench in zero gravity).

Whether floating effortlessly aboard shuttles or pioneering breakthroughs down on Earth, your remarkable journey inspires us all. May your birthday be as stellar as each moment you brilliantly navigated through meteor trails—and at least twice as enjoyable as astronaut ice cream! Here's to more cosmic adventures ahead—gravity optional and laughter guaranteed. Enjoy orbiting another trip around the sun!
