NASA astronaut Mike Fincke, a retired United States Air Force colonel, has announced his retirement from the agency’s Astronaut Office after an impressive 30-year career. Fincke is one of only 13 individuals to have launched into orbit from Earth aboard three different human-rated spacecraft.
Selected in 1996 as part of the 16th astronaut class, known as “The Sardines,” Fincke completed four spaceflights: two aboard Soyuz spacecraft, one on the Space Shuttle Endeavour, and one on the SpaceX Dragon Endeavour. In his farewell statement, Fincke expressed gratitude for the opportunity to work alongside remarkable colleagues and contribute to the development of spacecraft and the International Space Station (ISS).
Leadership in Space Missions
Fincke served as commander of the ISS on two occasions: first from October 22, 2008 to April 2, 2009, during Expedition 18, and again from December 7, 2025 to January 12, 2026, during Expedition 74. His leadership and experience have significantly impacted the ISS’s operations and research.
Reflecting on his career, Fincke stated, “I am profoundly grateful to my crewmates, the teams on the ground, our international partners, and the families who make this work possible.” He emphasized his commitment to fostering the next generation of engineers and explorers as humanity aims to return to the Moon and venture to Mars.
Contributions to the Commercial Crew Program
A significant portion of Fincke’s career was dedicated to the Commercial Crew Program, where he held the position of chief of the Astronaut Office’s Commercial Crew Branch. In January 2019, he was selected as one of three crew members for the Crewed Flight Test of the Boeing CST-100 Starliner spacecraft. However, due to delays in the program, Fincke transitioned to a backup pilot role.
Following the 2024 Crew Flight Test incident, he was reassigned to the SpaceX Crew-11 mission, which launched on August 1, 2025. This mission lasted 166 days but was cut short due to a medical emergency that required Fincke’s evacuation from the ISS.
Future of the Starliner Program
Fincke’s retirement marks a notable shift in the Starliner program, as he joins other astronauts who have departed after training on the spacecraft. The Starliner-1 mission has since been converted to a cargo-only flight to ensure operational safety. NASA continues to evaluate the timeline for the uncrewed Starliner-1 mission and its implications for future crewed missions.
As NASA prepares for the next steps in the Commercial Crew Program, it remains committed to advancing human spaceflight capabilities and ensuring that trained astronauts are ready for upcoming missions.
