History

Historical Context

The Apollo program, initiated in 1960, aimed to land humans on the Moon, fulfilling President John F. Kennedy's 1961 goal. On July 20, 1969, Apollo 11 successfully landed Neil Armstrong and Buzz Aldrin on the lunar surface, watched by over 500 million people. The program's achievements laid the groundwork for future space exploration, including NASA's Artemis missions, which seek to return humans to the Moon.
