This page contains philatelic information on the USA Viking-series spacecraft. Catalog numbers, years of issue, and notes 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 two USA Viking Mars missions launched in 1975 should not be confused with the much-later Swedish Viking scientific mission, which was launched in 1986.

1Viking-1 was the first operational spacecraft to make a soft landing on Mars; the earlier Mars-3 landed on the red planet but died soon thereafter and so was considered non-operational.
2A Viking-3 Mars lander/rover was a proposed follow-on mission to Viking-1 and 2.
3The Voyager Mars Program was a concept for Mars exploration, that turned into the Viking Program, and is not associated with the later Voyager Program. See https://en.wikipedia.org/wiki/Voyager_program_(Mars).
4The "Pioneer Project" was possibly a concept for Mars exploration, that turned into the Viking Program, and is not associated with the (later) Pioneer (planetary) Program.
5These covers include USA 1759 canceled at Cape Canaveral on 20 July 1978 along with phrases like "First day of issue Viking stamp, July 20 1978", and so are considered to be FDCs for USA 1759 even though they were not canceled at Hampton VA, the official FDOI location for the stamp. That date also means that these covers are Viking-1 anniversary covers since it is exactly the second anniversary of the Viking-1 landing on Mars. See here for some other Viking-1 anniversary covers.
6See here for a list of engraved/lithographed Russian definitive pairs known to exist with satellite overprints.


Below is a list of Viking-series spacecraft launch covers (including anniversary-of-launch covers, and launch-related event covers).

1"Late date stamp due to postal unrest" rubber-stamp cachet.
2These covers include USA 1759 canceled at Cape Canaveral on 20 July 1978 along with phrases like "First day of issue Viking stamp, July 20 1978", and so are considered to be FDCs for USA 1759 even though they were not canceled at Hampton VA, the official FDOI location for the stamp. That date also means that these covers are Viking-1 anniversary covers since it is exactly the second anniversary of the Viking-1 landing on Mars. See here for some other Viking-1 anniversary covers.
3The incorrect 1973 year in the hand cancel was hand-corrected to 1974.
4A Viking-3 Mars lander/rover was a proposed follow-on mission to Viking-1 and 2.
