Centennial Covers cachet

This page contains (selected) covers with "Centennial Covers" cachets, mostly on un-manned satellite (or scientific rocket) launch covers. These (~350) covers from 1962 thru 1986 (24 years), almost always without any logo (rare/exceptional items with a text logo are included in the list below), were produced by the late Edward Hacker of Huntsville AL. Centennial sold its remaining cover collection in 1984, but continued to produce covers for Space Shuttle events.

On this page, "selected" refers to covers for un-manned satellite (or scientific rocket) launches, or Space Shuttle launches whose missions included the deployment or recovery of un-manned satellites or payloads5 for Earth observation or other scientific studies. Other Centennial covers for manned missions also exist but are not included in this page.

Readers who know of additional information or images are invited to contact the authors using the e-mail addresses found at the link at the bottom of this page.

1Pioneer-5 and Explorer-6 were similar "paddlewheel" satellites. It is believed that Explorer-6 contained two short antennas on its "top", whereas Pioneer-5 contained only a single short antenna. When there are no antennas on top, the distinction is unclear, but of the two, Pioneer-5 is assumed.
2Uncommon launch cover with a "Centennial Covers" text logo. The same logo is also found on the following covers: NASA-Beechcraft 1st KSC landing, Space Hall of Fame, OV-101 2nd manned captive flight, OV-101 3rd manned captive flight, 1st SRB static firing, 4th Enterprise manned free flight, OV-101 ferry flight, Columbia arrives at KSC, STS-3 rollout, STS-3 launch, Atlantis leaves California, and Atlantis arrives in Florida.
3The Centennial cachets for launches of Intelsat-3-1 on 1968-09-19 and LES-6 and OV2-5 and OV5-2/4 on 1968-09-26 were inadvertently swapped.

5Payloads, as opposed to satellites, are neither deployed from, nor recovered to, the Space Shuttle cargo bay.
6There is disagreement among various sources on whether this should be called Telstar-3D or Telstar-3B!
