Early Milestones

• Sputnik - The Soviet Union's launch of Sputnik 1, the first artificial satellite, on October 4, 1957, shocked the U.S. and highlighted the need for advancements in space technology. This event marked the beginning of the Space Race.

• Explorer 1 - In response, the U.S. launched its first satellite, Explorer 1, on January 31, 1958. It discovered the Van Allen radiation belts, a significant scientific finding.

Formation of NASA

• NASA Creation - In response to the Sputnik crisis, the U.S. government established the National Aeronautics and Space Administration (NASA) on July 29, 1958, to coordinate and advance its space efforts.
• Project Mercury - NASA's first major program aimed to send a human into space. The program successfully launched Alan Shepard, the first American in space, on May 5, 1961, aboard Freedom 7. John Glenn followed as the first American to orbit the Earth on February 20, 1962, in Friendship 7.

Moon Missions

• Apollo Program - Initiated in 1961, the Apollo program aimed to land a man on the Moon and return safely. President John F. Kennedy's famous speech on May 25, 1961, set the ambitious goal of landing on the Moon before the decade's end.
• Apollo 11 - On July 20, 1969, Apollo 11 achieved this goal when astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the Moon. Armstrong's words, "That's one small step for man, one giant leap for mankind," became iconic.
