This page contains philatelic information on the SYNchronous COMmunications (Syncom) series 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 five Syncom-4 series satellites were also called Leasat (LEAsed SATellite).

Syncom and Early Bird / Intelsat-1 are similar cylindrical spin-stabilized spacecraft, but Early Bird is taller (smaller width-to-height aspect ratio), and Syncom has a larger nozzle in relation to the spacecraft body.

Items depicting a satellite based on the Syncom publicity photo are highlighted in pale yellow in the table below.

1Many Syncom images are similar to NASA's Syncom publicity photo, which does not look like any of the Syncom reference images provided. This publicity photo was created by Bob Special, a NASA technician at Cape Kennedy. The publicity photo shows a flame coming out of Syncom's apogee motor. This was probably to make the image more dramatic. Some of the stamp reproductions of the publicity photo eliminate the flame, as noted. It must also be pointed out that the real Syncoms had a larger cone-shaped nozzle extending outward from the apogee motor than shown on the publicity photo.


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

1Many Syncom images are similar to NASA's Syncom publicity photo, which does not look like any of the Syncom reference images provided. This publicity photo was created by Bob Special, a NASA technician at Cape Kennedy. The publicity photo shows a flame coming out of Syncom's apogee motor. This was probably to make the image more dramatic. Some of the stamp reproductions of the publicity photo eliminate the flame, as noted. It must also be pointed out that the real Syncom had a larger cone-shaped nozzle extending outward from the apogee motor than shown on the publicity photo.
2Pioneer-3 and 4 are basically identical.
