How did America respond to Sputnik
America was worried that Russia could start bombing them if they wanted. The fear of Russia being the first ones in space was amplified by the Cold War, and many Americans thought that by dominating space, the Russians would be able to launch any kind of attack they felt like at any time on the U.S. from space without any opposition, because the U.S. had no satellites in space. It started the space race, which was a period of time during which the United States rushed to get satellites up into space as well, to close the rift that had emerged between Russian and American space technology.
