Explanation:

  The space race was a competition during the Cold War times between the Soviet Union and the United States for dominance in spaceflight capability.

  The race began in 1955 when both countries announced with few days of distance their intention to launch artificial satellites. USSR was the first to successfully launch one, the Sputnik 1, and was also the first in putting a human in space, Yuri Gagarin. After being beaten in these two points, the United States created NASA and became the first country to land humans on the moon. The improvement in science and math education was fundamental for the achievement.
