This database from the Union of Concerned Scientists is a listing of operational satellites currently in orbit around the Earth. The database includes basic information about more than 800 satellites and their orbits, but does not contain the detailed information necessary to locate individual satellites. Users can find information about a particular satellite; identify sets of satellites having a common characteristic, such as altitude or mission; and sort or aggregate data about the whole population of satellites.
LexisNexis offers two major databases for NPS users: nexis.com and LexisNexis Academic. This one, LexisNexis Academic is designed with a simplified search interface, uses a targeted subset of LexisNexis, and requires no special password. (NPS users of LexisNexis Academic are proxy-authenticated.) Documents come from a huge variety of newspapers, news wires, magazines, news weblogs, broadcast transcripts and more, and are provided in full-text (ASCII text only, no graphics). If you need additional information about differences between this product and the larger LexisNexis (as well as the necessary password for LexisNexis) please Ask a Librarian.
