A-train
|
Below is a checklist of A-train constellation satellites postal items (stamps, souvenir sheets, aerogrammes, postal cards, etc.). Catalog numbers, years of issue, and notes on the satellites featured are given when available. There are currently 5 satellites in the A-train constellation: EOS-Aqua, EOS-Aura, CloudSat, CALIPSO, and PARASOL. A 6th satellite, OCO, will be added to the A-train in late 2008. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.
Farther below is a list of A-train launch covers, anniversary-of-launch covers, and launch-related event covers.

*Scott catalog number, unless prefixed with Mi or BL for Michel; "i" prefix denotes imperforate version.
**FDC = first day cover; SS# = souvenir sheet, MS# = miniature sheet, where # = number of stamps in sheet, and the numbers in parentheses are the catalog numbers of the stamps in the sheet.
1The U.S. EOS-Aura from 2004 should not be confused with the French D-series satellite (D-2B / Aura) from 1975, which goes by the same name.
2EOS-Terra is the "morning" compliment to the "afternoon" EOS-Aqua, but it is not part of the A-train satellite constellation.
Below is a list of A-train launch covers, anniversary-of-launch covers, and launch-related event covers.
