Explorer 1 was the first satellite launched by the United States in 1958 and was part of the U.S. participation in the International Geophysical Year (IGY). The mission followed the first two satellites, both launched by the Soviet Union during the previous year, Sputnik 1 and Sputnik 2. This began a Space Race during the Cold War between the ...

In the early 1950s, there was a challenge to launch an artificial satellite for the International Geophysical Year (1957–58). An effort for this was the American Project Vanguard . After the Soviet space program launched the world's first artificial satellite ( Sputnik 1 ) on October 4, 1957, the United States stepped up its own efforts.
The timeline of first Earth observation satellites shows, in chronological order, those successful Earth observation satellites, that is, Earth satellites with a program of Earth science. Sputnik 1 , while the first satellite ever launched, did not conduct Earth science.
NASA continued to use the name for an ongoing series of relatively small space missions, typically an artificial satellite with a specific science focus. Explorer 6 in 1959 was the first scientific satellite under the project direction of NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. [3] [4]
