What impact did Sputnik have on the world?

Sputnik made it possible to test satellite pressurisation, to study radio wave transmission and the density of the atmosphere, and allowed scientists to learn how to track objects in orbit. Sputnik 1 orbited Earth every 96 minutes, and the fact that it passed over the USA seven times a day worried many Americans.
