Before Neil Armstrong’s historic steps on the Moon in 1969, NASA’s Ranger 9 mission paved the way. Launched on March 24, 1965, Ranger 9 was the final spacecraft in NASA’s Ranger program, designed to map the Moon’s surface and identify potential landing sites. Unlike previous missions, it targeted the Alphonsus Crater, an area believed to have volcanic activity. Equipped with six high-resolution cameras, Ranger 9 sent back 5,814 images of the lunar landscape, with the final image captured just 0.25 seconds before impact. The mission, broadcast live on TV, provided invaluable insights into the Moon's terrain and demonstrated that controlled impacts were possible. Ranger 9’s successful mission boosted confidence for future Apollo landings, proving critical to the success of human lunar exploration. While it didn’t leave a physical footprint, it played a key role in enabling humanity's giant leap onto the Moon.
