The NSSDC is operated by the Goddard Space Flight Center of NASA.
The Master Catalog enables purposeful Search for:
When searching for spacecraft, they can be searched by name or start date, also specifying the intended use is possible. In addition to a description, which often includes images in research satellites or space probes, it also has a bottom with path data. Similarly, there are links to the experiments, publications and images if they are available. ( For messages or military satellites, there are only an often very brief description and path data. )

All spacecraft have in this catalog a unique number that NSSDC ID. It is composed from the start year, a dash, the starting number (how many start in the year, three digits ) and one to three letters that indicate to take into account what spacecraft or other component of their start up.
