How did John Glenn make or affect world history?

Answer 1

John Glenn made a significant impact on world history as the first American to orbit the Earth in 1962 during the Mercury-Atlas 6 mission, which marked a pivotal moment in the Space Race between the United States and the Soviet Union. His successful mission helped to boost American morale and reaffirmed the U.S. commitment to space exploration. Later, Glenn became a symbol of public service and bipartisan cooperation as he served as a U.S. senator and returned to space at age 77 on the Space Shuttle Discovery in 1998, inspiring generations to pursue careers in science and exploration. His contributions not only advanced space technology but also fostered international collaboration in scientific endeavors.
