camera. Wilmore was selected as a pilot by
NASA in July 2000 and reported for training that August 2000. Following the completion of two years of training and evaluation, Wilmore was assigned technical duties representing the Astronaut Office on all propulsion systems issues including the
Space Shuttle Main Engines,
solid rocket motor,
external tank, and also served on the astronaut support team that traveled to the
Kennedy Space Center,
Florida, in support of launch and landing operations.
Expedition 41/42 Wilmore returned to space in September 2014 as a member of the
Soyuz TMA-14M long duration International Space Station crew. During this mission, humans manufactured off world for the first time. The International Space Station's 3-D printer, designed and built by
Made In Space, Inc., was used to print a tool with a design file transmitted from the ground to the printer. The tool was a ratchet wrench needed by Wilmore, who would have had to wait for the tool to be delivered on the next supply mission from Earth. The wrench was later returned to the ground for analysis and testing, along with the other parts printed in space.
Boeing Crew Flight Test & Butch Wilmore, Space Force Col. Nick Hague - and Roscosmos cosmonaut
Aleksandr Gorbunov land in a Dragon spacecraft off the coast of Tallahassee, FL., March 18, 2025. On October 7, 2020, NASA and Boeing announced Wilmore would join astronauts
Michael Fincke and
Nicole Mann for NASA's
Boeing Crew Flight Test (CFT), the inaugural crewed flight of the
CST-100 Starliner launching to the International Space Station in 2021. On April 18, 2022, NASA said that it has not finalized which of the cadre of Starliner astronauts, including Wilmore, Fincke, and
Sunita Williams, would fly on the Crewed Flight Test mission or the first
operational Starliner mission. On June 16, 2022, NASA confirmed that CFT will be a two-person flight test, consisting of Wilmore and Williams. On June 5, 2024, Starliner was launched successfully to orbit with Williams as the spacecraft's pilot. On June 6, Starliner docked to the
ISS after over a day in space. The mission was meant to last eight days, ending with a landing in the
southwestern United States on June 14. However, the capsule's thrusters malfunctioned as Starliner docked with the ISS. Despite months of testing, NASA felt it was not able to understand why the thrusters malfunctioned and decided that it was too risky to return Wilmore and Williams to Earth aboard Starliner. The Boeing Starliner spacecraft returned uncrewed on September 6, 2024, and landed intact at White Sands Space Harbor, New Mexico at 12:01 a.m., September 7, after three months in space docked to the ISS. In December 2024, it was announced that Wilmore and Williams would return to
Earth no earlier than late March 2025 on a
SpaceX Dragon capsule. On March 18, 2025, Williams and Wilmore finally returned to Earth on the
SpaceX Dragon capsule with the other crew members of
Crew-9. On August 6, 2025, NASA announced Wilmore's retirement from the agency. == Awards and honors ==
