the united states response to the successful orbit of sputnik in 1957 was to
Sputnik crisis The Sputnik crisis was a period of public fear and anxiety about the perceived technological gap between the United States and Soviet Union caused by the launch of Sputnik 1, the world's first artificial satellite, launched by the Soviet space program.[1] The crisis was a key event in the early Cold War that triggered the creation of NASA and Space Race between the two superpowers. The satellite was launched on October 4, 1957 from the Baikonur Cosmodrome. The term was coined by then US President Dwight D. Eisenhower.[citation needed]
Satellite In 1957 the Soviet Union launched the world's first artificial satellite, Sputnik 1. Since then, about 6,600 satellites from more than 40 countries have been launched. According to a 2013 estimate, 3,600 remained in orbit.[1] Of those, about 1,000 were operational;[2] while the rest have lived out their useful lives and become space debris. Approximately 500 operational satellites are in low-Earth orbit, 50 are in medium-Earth orbit (at 20,000 km), and the rest are in geostationary orbit (at 36,000 km).[3] A few large satellites have been launched in parts and assembled in orbit. Over a dozen space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, a few asteroids,[4] a comet and the Sun.
