The International Designator (or NSSDC ID) is an international naming convention for satellites. It consists of the launch year, a 3-digit incrementing launch number of that year and up to a 3-letter code representing the sequential id of a piece in a launch. For example, 1957-001A is Sputnik 1's launch vehicle and 1957-001B is the actual Sputnik 1 satellite. The number reveals that it was launched in 1957 and that it was the first launch made that year. Another example is 1990-037B, the Hubble Space Telescope, which was the 37th launch world wide in 1990. 1990-037A is the Space Shuttle Discovery on mission STS-31, which was to carry the Hubble telescope into space.
