NASA’s Oldest Active Astronaut Marks 70th Birthday in Space
NASA astronaut Don Pettit, the oldest active-duty American astronaut, celebrated his 70th birthday in an extraordinary way—returning to Earth after a seven-month mission aboard the International Space Station (ISS). Pettit, along with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner, landed in Kazakhstan on Sunday, April 20, 2025, marking the end of a journey that spanned 220 days in orbit.
A Historic Milestone
The Soyuz MS-26 spacecraft carrying Pettit and his Russian counterparts touched down in a remote area southeast of Zhezkazgan, Kazakhstan, at 6:20 am local time (0120 GMT). The landing coincided with Pettit’s milestone birthday, making him one of the oldest astronauts to actively serve in space. According to NASA, Pettit is “doing well and in the range of what is expected for him following return to Earth.”
Mission Highlights
During their 220-day mission, the crew orbited the Earth 3,520 times, covering a distance of approximately 93.3 million miles. This was Pettit’s fourth spaceflight, adding to his already impressive record of 590 days spent in orbit over his 29-year career. The mission focused on critical scientific research, including advancements in water sanitation technologies, studying plant growth under varying conditions, and investigating fire behavior in microgravity.
The Landing
NASA images captured the Soyuz capsule’s descent, with its parachute deploying against the backdrop of a sunrise. After landing, the astronauts were carried to an inflatable medical tent for initial health assessments. Pettit and his crewmates gave thumbs-up gestures, signaling their safe return. Following the medical checks, Pettit was scheduled to travel to Karaganda, Kazakhstan, before boarding a NASA plane to the Johnson Space Center in Texas.
Scientific Contributions
The research conducted during the mission holds significant implications for future space exploration and Earth-based applications. The team explored innovative water sanitization methods, which could benefit communities lacking clean water access. Additionally, experiments on plant growth in microgravity aim to enhance food production systems for long-duration space missions. Studies on fire behavior in microgravity contribute to safety protocols for spacecraft and other confined environments.
A Legacy in Space
Pettit’s career is marked by numerous achievements, including his role as a flight engineer for Expeditions 71 and 72. His extensive experience and contributions to space science have solidified his legacy as a pioneer in the field. While Pettit is NASA’s oldest active astronaut, John Glenn remains the oldest person to fly in orbit, having completed a mission at the age of 77 in 1998.
US-Russia Collaboration in Space
The mission also highlights ongoing collaboration between NASA and Roscosmos, one of the few remaining areas of cooperation between the United States and Russia amid strained political relations. This partnership underscores the importance of international teamwork in advancing space exploration.
As Pettit returns to Earth, his contributions to space science and exploration continue to inspire future generations of astronauts and researchers. His 70th birthday serves as a reminder of the limitless possibilities of human achievement, even in the most challenging environments.
