AEROS^[5]: 12satellites were to study theaeronomy i. e. thescience of the upperatmosphere andionosphere, in particular theF region under the strong influence ofsolar extremeultravioletradiation. To this end thespectrum of this radiation was recorded aboard by one instrument (of typeHinteregger) on the one hand and a set of 4 other instruments measuring the most important neutral uand iononized parameters at the satellite's position on the other.

AEROS was built byBall Aerospace for aco-operative project betweenNASA and theBundesministerium für Foschung und Technologie (BMwF),Federal Republic of Germany.^[5]: 82

Named for theGreek god of the air at the suggestion of the BMwF .^[6]

AEROS A andB carried identical instrumentation only the instrument measuring short scale variations of the electron density didn't work onA. A third Aeros C was planned forEarth Resources studies in a 3-axis spin-stabilized configuration, to be launched by aShuttle in 1986.^{[5](Needs research)}
