The MICA auroral sounding rocket (Magnetosphere-Ionosphere Coupling in the Alfvenic resonator) was launched from Poker Flat, Alaska in February 2012 into the wake of a large westward travelling surge. With the MICA rocket, our group has turned our attention from the details of acceleration and precipitation structures, to the details of the ionospheric plasma response to auroral drivers. For this mission, we used extensive groundbased arrays, and in situ thermal particle instrumentation, together with a rigourous 2-d model of ionospheric chemistry and plasma physics. The MICA observations include small-scale structuring at the conductivity boundary of an arc edge, consistent with literature descriptions of ionospheric feedback effects. In this presentation, we discuss the MICA field campaign and observations, together with a discussion of a localized cubesat swarm mission concept which could further investigate these effects.
