Let's make this birthday one to remember.

83 years old (Born on October 31, 1941)

Happy Birthday, Dan Alderson! Navigating spacecraft through the cosmos is impressive enough, but guiding Voyagers 1 and 2 beyond our solar system? Now that's just showing off. Your software has boldly gone where no code has gone before—literally!

And let's not forget your literary fame in "Lucifer's Hammer." Surviving fictional apocalypses while simultaneously plotting real-life interstellar journeys? Only you could multitask like that. Here's to another orbit around the sun filled with cosmic adventures, fewer asteroid scares, and plenty of laughs along the way. Keep reaching for the stars—but maybe steer clear of rogue comets this year!
