This page contains philatelic information on the [Mercury and Gemini-deployed] Sub-satellites. Catalog numbers, years of issue, and notes on the satellites featured are given when available. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.

The intent is to focus on sub-satellites, not on the Mercury and Gemini missions that carried those sub-satellites. Regardless, a selected sample of covers without any mention of the sub-satellties are included due to the lack of covers that mention the sub-satellites on those missions.
