On July 20, 1969, the world watched on televisions or listened on radios as Neil Armstrong and Buzz Aldrin took the first-ever steps on the Moon. Once considered an impossible dream, the United States created the APOLLO program with one goal in mind-landing on the Moon. After many years of hard work, sacrifice, and dedication, the APOLLO 11 mission made that dream a reality. Author Carl R. Green explores one of the most monumental achievements in human history.
