A relentlessly curious astronaut who turned the International Space Station into a workshop for ingenious scientific improvisation.
Don Pettit approaches spaceflight with the mind of a tinkerer and the eye of a poet. A chemical engineer by training, he didn't join NASA's astronaut corps until his mid-40s, bringing a seasoned scientist's perspective to orbit. On his first long-duration mission to the ISS, he became famous for his 'Saturday Morning Science' experiments—using simple, everyday items like duct tape and water to demonstrate physics in microgravity for audiences back on Earth. Pettit is a prolific inventor in space, creating tools like the zero-g coffee cup that allows astronauts to drink without a straw, and a barn-door tracker for capturing stunning astrophotography. His cumulative time in space, over 590 days across three expeditions, makes him one of NASA's most experienced fliers. Even in his 70s, he remains an active astronaut, embodying a spirit of lifelong curiosity and proving that space is not just for exploration, but for continuous, hands-on discovery.
1946–1964
The largest generation in history at the time. Shaped by postwar prosperity, the Vietnam War, the sexual revolution, and Watergate. They questioned every institution their parents built — then ran them.
Donald was born in 1955, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.

He is a skilled machinist and often designs and builds his own experimental hardware for space missions.
He spent six weeks in Antarctica on a meteorite-gathering expedition with the ANSMET program.
He is, as of 2026, NASA's oldest active astronaut.
He brought a bag of 100-year-old coffee beans to space on one mission and brewed coffee in microgravity.
He holds a patent for the 'Coffee Cup for Use in Microgravity.'
