This page contains philatelic information on the (later) Pioneer-series (planetary) 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 first part of the Pioneer series, Pioneer-0 — Pioneer-E [which failed], were primarily lunar, solar, and inter-planetary exploration satellites. Those (earlier) Pioneer (non-planetary) satellites are covered elsewhere. The second part of the series, Pioneer-10 — Pioneer-13, were for exploration of the planets, including specific missions of two Pioneers to Jupiter/Saturn and two Pioneers to Venus. Only these (later) Pioneer (planetary) satellites are included here.

1Pioneer-10 and 11 were also known as Pioneer-Jupiter-1/2, not Jupiter-10/11.
2Image of the satellite on this item has three identical booms, whereas Pioneer-10/11 have only two such booms, the third boom being much longer and slimmer.
3This WERABA-76 (exhibition) cinderella (vignette) contains reproductions of Switzerland 496, USA 1556, and Russia 4044
4Pioneer-11 was the only one of the Pioneer-10/11 pair to fly-by Saturn.
5See here for a list of engraved/lithographed Russian definitive pairs known to exist with satellite overprints.
