Master Catalog

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. )


See main article COSPAR designation

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. The numbering almost always begins with the spacecraft. The available in the Internet catalog only contains information about the spacecraft in the rule.
