This page contains philatelic information on the A-train constellation 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.

There are 5 satellites in the A-train constellation: EOS-Aqua, EOS-Aura, CloudSat, CALIPSO, and PARASOL. A 6th satellite, OCO, failed upon launch in 2009. Another satellite, Glory, is expected to join the A-train in 2010.

*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.
