For example, on a satellite sheet you may click for data on its country of origin, mission, launch vehicle, etc. Satellites are sorted alphabetically by name and gathered by space program when possible. Numerous other themes are available such as the countries of origin, the launch vehicles, missions, etc. Those indexes are chronological. The encyclopedia is full of popup windows with technical data and maps.
Launched satellites are available in most indexes that apply.
You can find them in the launch schedule section and with the search tools. The easiest way to find something is to question the searching tool. You also can browse through indexes. Our WWW edition has external links to such information. From a telecommunication satellite fact sheet you will find a direct link to the Lyngsat chart which contains the precise listing of content broadcast by the satellite.
