| Centennial Covers | Centennial-like |
This page contains (un-manned satellite and other selected) covers with "Centennial Covers" (and Centennial-like) cachets, mostly on un-manned satellite (or scientific rocket or balloon) 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.
The covers found in this page are primarily for un-manned satellite (or scientific rocket or balloon) launches or events. Covers for manned and other missions are included if they contain an element of interest to the authors.
Blue highlighting is used to identify postal items only of interest for completing this collection of numbered covers, as they are not in the domains of primary interest for the authors.
The "Centennial-like" section contains covers that have cachets with elements (usually, depictions of rockets or satellites) found in true Centennial cachets, but which lack the descriptive text always found in them, or include such text in a style unknown for them.
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 [Covers] 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! See Boeing's Telstar-3 - AT&T's Advanced New Communications Satellite.
7To demonstrate the structural and thermal integrity of the space vehicle and to verify adequacy of the Block II heatshield design for entry at lunar return conditions; also, a 70 mm still camera photographed Earth's surface every 10.6 seconds, taking 715 good-quality high-resolution pictures.
