The Space Race between the United States and the Soviet Union reached a peak in 1969
when the U.S. put the first humans on the Moon. However, the competition between the
two countries’ space programs continued for many more years.


Reaching the Moon


OnMay25,1961,shortlyafterthefirstAmericanwentintospace,PresidentJohnF.Kennedy
presented the following challenge to the U.S. Congress:


”I believe that this nation should commit itself to achieving the goal, before this decade
is out, of landing a man on the Moon and returning him back safely to the Earth.
No single space project in this period will be more impressive to mankind, or more
important for the long-range exploration of space; and none will be so difficult or
expensive to accomplish.”

Eight years later, NASA’s Apollo 11 mission achieved Kennedy’s ambitious goal. On July
20, 1969, astronauts Neil Armstrong and Buzz Aldrin were the first humans to set foot on
the moon, as shown inFigure23.23.
