1The French D-series satellite (D-2B / Aura) from 1975 should not be confused with the USA EOS-Aura from 2004, which goes by the same name.
3See here for a list of engraved/lithographed Russian definitive pairs known to exist with satellite overprints.
4The Tartari Republic overprints of Cuba 3019 span blocks of 4 Russian definitives but not necessarily the same blocks of 4 that divide the strips into 5 overprinted stamps. See an example of how the stamps are divided differently in terms of overprints (in red) vs. divided for use as stamps (in green). Since our emphasis is on the D-series satellite, in the table above we present the strips divided in terms of overprints.


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