ASTEX (FRUSA)

FRUSA
(and other US military weather-related
and scientific/research satellites)


This page contains philatelic information on the FRUSA (Flexible Rolled-Up Solar Array) (and other US military weather-related and scientific/research 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.

FRUSA is also known as ASTEX (Advanced Space Technology EXperiment).

The USAF Geophysical Research Satellite (GRS) from 1963 should not be confused with the West German Azur/GRS from 1969, which goes by the same acronym.
