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 covers 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.
Most of the postal items listed below are also found in other pages of the Un-manned Satellite Philately website. However, below are also a few items not found elsewhere in the website because they are not of direct interest to the authors. They are nevertheless included here to make this list of named covers more complete. Such items are highlighted in blue.
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.
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.
