1957—Sputnik Circles Earth
The Soviet Union launches the satellite Sputnik I, which becomes the first artificial object to orbit the Earth. It orbits for two months and provides valuable information about the density of the upper atmosphere. It also panics the United States into a space race that eventually culminates in the U.S. moon landing.
