Don Pettit Oldest Serving US Astronaut Returns to Earth on His 70th Birthday

In a historic and heartwarming moment, Don Pettit, the oldest serving U.S. astronaut, safely returned to Earth on April 21, 2025, marking his 70th birthday. Pettit’s spacecraft, Soyuz MS-26, made a parachute-assisted landing in Kazakhstan, bringing him and his two Russian crewmates back from the International Space Station (ISS). Their return concludes a 220-day mission, adding to Pettit’s already impressive space career. With this journey, he has now logged 590 days in space over four missions, reinforcing his legacy as one of NASA’s most seasoned astronauts. Though not the oldest human to go to space—that record remains with John Glenn, who flew at age 77—Pettit’s dedication and longevity are remarkable achievements in space exploration.
