[edit]
While the sources are reliable and include Scientific American, etc., the sources differ as to the type of satellite GGSE-4 was, its mass, etc. Someone ought to look into that. This is probably because the POPPY program was classified until 2005 (a 40-year period). XavierItzm (talk) 17:59, 30 January 2020 (UTC)
