Supersonic and Subsonic Measurements of Mesospheric Ionization

Abstract

An Arcas rocket-parachute system was used at night to compare supersonic and subsonic ionization measurements below 75 km. A hemispherical nose-tip probe was used on ascent and a parachute-born blunt probe was employed on descent to measure polar conductivities, which were due entirely to positive and negative ions.
