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.
