History: need the answer asap: what term was given to the competition between the united states and the soviet union for superiority in extraterrestrial exploration? missile gap bomber gap arms race space race

The competition between the United States and the Soviet Union for superiority in extraterrestrial exploration was called Space Race.

America had reason to compete  against the Soviet Union in Space Race: Sputnik beat the United States to space in 1957, damaging its national pride and igniting fears of Soviet technology. The Soviet Union wanted space just as badly as the United States did. The Soviet Union and the United States differed in how they propagandized the Space Race, but they shared the common bond of actually having space programs.

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
