December 18, 2025. NASA astronaut and retired U.S. Navy Captain Lee Morin concluded his 30-year career with the agency. He flew on the Space Shuttle Atlantis (STS-110) mission as a mission specialist, and subsequently led the Rapid Prototyping Laboratory, overseeing technology development for the International Space Station, NASA’s Commercial Crew Program, and the Artemis program.

A New Hampshire native and physician by training, Lee Morin flew aboard the Space Shuttle Atlantis (STS-110) in 2002. During this mission, a key truss segment was delivered to the space station. The flight also marked the first use of the station's robotic arm to assist astronauts during spacewalks, as well as the first spacewalks conducted via the Quest airlock module. Morin performed two spacewalks, spending a total of 14 hours and 9 minutes outside the station. His total time in space amounted to 10 days and 19 hours.

Following his spaceflight, Morin used the experience he gained to improve how astronauts interact with spacecraft systems. He contributed to the development of software and display interfaces used during missions aboard the space station and the Orion spacecraft, leading an astronaut team that created a unified graphical interface for space station crews.

Morin was selected for the astronaut corps in 1996. He holds several advanced degrees, including master's degrees in biochemistry, public health, and physics, and earned his medical degree from New York University. Prior to joining NASA, he served as a flight surgeon and diving medical officer in the U.S. Navy and held key positions in the field of aerospace medicine.
