Based on the world record nomination from America Records Institute (AMRI) and Decision No. WK/USA.INDIA/637/2021/No.93, World Records Union (WorldKings) officially declared Neil Armstrong is the first person to walk on the moon on January 2, 2021.
Before becoming an astronaut, Armstrong was an officer in the U.S. Navy and served in the Korean War. After the war, he earned his bachelor's degree at Purdue University and served as a test pilot at the National Advisory Committee for Aeronautics (NACA) High-Speed Flight Station, where he logged over 900 flights. He later completed graduate studies at the University of Southern California.
A participant in the U.S. Air Force's Man in Space Soonest and X-20 Dyna-Soar human spaceflight programs, Armstrong joined the NASA Astronaut Corps in 1962. He made his first space flight as command pilot of Gemini 8 in March 1966, becoming NASA's first civilian astronaut to fly in space.
Armstrong's second and last spaceflight was as commander of Apollo 11, the first manned Moon landing mission in July 1969. Armstrong and Lunar Module pilot Buzz Aldrin descended to the lunar surface and spent two and a half hours outside the spacecraft, while Michael Collins remained in lunar orbit in the Command/Service Module.
Along with Collins and Aldrin, Armstrong was awarded the Presidential Medal of Freedom by President Richard Nixon. President Jimmy Carter presented Armstrong the Congressional Space Medal of Honor in 1978. Armstrong and his former crewmates received the Congressional Gold Medal in 2009. Armstrong died in Cincinnati, Ohio on August 25, 2012, at the age of 82, after complications from coronary artery bypass surgery.
