Charles Duke is a man who went to space. 
Charles Duke was a pilot. 

Charles Duke was a pilot and an astronaut. 

In 1966, NASA chose him to be an astronaut. He helped with many space missions. He was the voice for Mission Control during Apollo 11. This was the first trip where people landed on the Moon. 
Duke became the 10th person to walk on the Moon. He was 36 years old. This made him the youngest person to walk there. He and John Young explored the Moon's surface. They did three EVAs, which are walks outside the spacecraft. 
Charles Moss Duke Jr. is a famous American astronaut and pilot. 

His journey to space involved many steps of training. First, he learned to fly many different types of planes. He graduated from the United States Naval Academy in 1957. Later, he went to the Aerospace Research Pilot School in California. He also studied at the Massachusetts Institute of Technology to learn about aeronautics and astronautics. This means he studied how things fly and how they work in space. He even helped with research on guidance systems for the Apollo project. 
Duke's path to NASA began with a newspaper article. In 1965, he saw an ad for NASA's fifth group of astronauts. He applied and became one of 19 men selected in April 1966. Before his own Moon walk, he helped other missions. He was part of the support crew for Apollo 10. He also worked as the CAPCOM for Apollo 11. CAPCOM is the person at Mission Control who talks directly to the astronauts in space. His voice became very famous during that historic first Moon landing. 
There are many important facts about his time in space. During the Apollo 16 mission, Duke and John Young landed at the Descartes Highlands. They performed three extravehicular activities, or EVAs. An EVA is a walk outside of the spacecraft. Duke spent 21 hours and 38 minutes doing these walks. He also logged a total of 265 hours in space. He even left a special gift behind on the Moon. He left a portrait of his family on the lunar surface.
Duke's life shows how much hard work it takes to explore. He grew up in North Carolina and South Carolina. He was an Eagle Scout when he was a boy. He spent much of his life flying, with over 4,147 total flying hours. Most of those hours were spent in jet aircraft. He eventually became a brigadier general in the Air Force. Even though he retired from NASA in 1976, his work helped us understand the Moon much better.

Duke's path to the Moon began with extensive training in aviation and engineering. He graduated from the United States Naval Academy in 1957. Although he was not an athlete, he played on the academy's golf team. 

After his initial training, Duke served as a fighter pilot in West Germany. He was stationed at Ramstein Air Base with the 526th Fighter-Interceptor Squadron. This assignment was during the height of the Cold War and the Berlin Crisis of 1961. His squadron was on high alert to intercept aircraft crossing the border from East Germany. Seeking further education, Duke attended the Massachusetts Institute of Technology (MIT). There, he earned a Master of Science degree in aeronautics and astronautics in 1964. During his studies, he performed statistical analysis for the Project Apollo guidance systems. This work helped him prepare for his future role in space exploration.
In 1965, Duke applied to NASA's fifth astronaut group after seeing an announcement in the Los Angeles Times. He underwent rigorous medical and psychological testing at Brooks Air Force Base. This included encephalograms and sessions in a human centrifuge. In April 1966, he was one of 19 men selected for the program. Before his own lunar landing, Duke served in vital support roles. He was a member of the support crew for Apollo 10. He also served as the CAPCOM for Apollo 11, the first crewed Moon landing. As CAPCOM, he was the voice of Mission Control communicating with the crew. His Southern drawl became famous when he spoke to the astronauts during their landing on the Moon.
Duke's experience with the Apollo program also included serving as the backup Lunar Module pilot for Apollo 13. This mission faced significant challenges when a crew member, Ken Mattingly, was replaced due to rubella exposure. Mattingly was later reassigned as the command module pilot for Duke's own mission, Apollo 16. 

Throughout his time in space, Duke engaged in scientific study and left lasting marks on the Moon. He participated in specialized geology training to better understand the lunar surface. 

After retiring from NASA on January 1, 1976, Duke continued his service in the Air Force Reserve. He eventually rose to the rank of brigadier general and retired from the Air Force in June 1986. His career is defined by massive amounts of flight time. He logged 4,147 total flying hours, with 3,632 of those hours in jet aircraft. His journey from a young boy making model aircraft to a Moon walker demonstrates the intense preparation required for spaceflight. His legacy remains a significant part of the history of human exploration of the solar system.
