The SPACEWARN Bulletin is intended to serve as an international communication mechanism for the rapid distribution of information on satellites and space probes. The material it contains is based on guidelines in "COSPAR Guide to Rocket and Satellite Information and Data Exchange," COSPAR Transactions #8, December 1972, and various Committee on Space Research (COSPAR) resolutions.
The SPACEWARN Bulletin is issued on the first of each month and provides a listing of launches and brief details of each launch from the preceding month. Also included are the status of some specialized fleets (such as GLONASS and GPS) or links to other sites that provide current status.
Back issues of the SPACEWARN Bulletin are available at: http://nssdc.gsfc.nasa.gov/spacewarn/.
Notifications of additions and updates to the SPACEWARN Bulletin are no longer sent to users via e-mail.
