Military weather-related and scientific/research/technology satellites

Below are checklists of Military weather-related and scientific/research/technology satellites, including launch dates and images of the satellites. This is a work in progress, and completeness is our goal. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.

In general, military communications satellites are found on the communications satellites page.

Unlike most of our web pages, no attempt is made to be complete for the satellite series or groups accompanied by "selected" on this page.
