A Navy SEAL has successfully completed the NASA Astronaut program.

Last week, Lieutenant Jonny Kim graduated from the course and now is qualified for missions to the International Space Station and the moon.

Kim enlisted in the Navy in 2002. After successfully completing the grueling Basic Underwater Demolition/SEAL (BUD/S) and SEAL Qualification Training (SQT) courses, he joined SEAL Team Three. He deployed twice to Iraq. For his actions on the battlefield, Kim earned the Silver Star, the nation’s third-highest award for valor under fire.

He then accepted a commission and joined the Navy Reserves. He also went to Harvard Medical School, from which he graduated in 2016.

“A true privilege and honor to walk among the NASA Astronaut Corps with my brothers and sisters,” said Kim. “We know there are many qualified and deserving candidates out there — we’re the lucky ones to represent humanity. Let’s work towards a better future for our world and our children.”

Kim was into the first year of his four-year residency at the Massachusetts General Hospital when he learned that NASA had accepted his application.

Talking about the NASA Astronaut program, Kim said that “we do more than space. NASA continues to make contributions to aviation to improve the lives of all on Earth. Quiet supersonic travel and electric aircraft standards are just two of the many innovations we are working hard to bring to the public.”
