The purpose of the AEROS spacecraft mission was to study the state and
behavior of the upper atmosphere (thermosphere) and the ionospheric F-region.
Of particular interest was the influence of solar ... ultraviolet radiation
on the structure, photochemistry and dynamics of the atmosphere above
100 km altitude.
INSTRUMENTATION: Five experiments provided data on the temperature
and density of F-region electrons, ions and neutral particles, on the
composition of ions and neutral particles, and on the solar ultraviolet
flux incident on the topside ionosphere.
SPACECRAFT: The AEROS satellite had a circular cylindrical shape
with a diameter of 0.914 meter and a height of 0.710 meter.
ORBIT: AEROS was launched into an elliptical, polar, and nearly
sun-synchronous earth orbit. The spacecraft was spin stabilized at
10 rpm and was oriented with the spin axis toward the sun.
