The science objective for the Ion-Neutral during Active Aurora (INCAA) sounding rocket mission is to understand the interactions between the plasma and the neutral atmosphere during active aurora, and how this interaction affects energy deposition in the E-region ionosphere. The measurement strategy is to measure the ion demagnetization altitude and altitude resolved Joule heating rate. The mission will measure all terms in the ion momentum equation with altitude resolution of less than one kilometer, and will also use complimentary groundbased instrumentation from incoherent scatter radar and Fabry Perotinterferometers to quantify the local ionospheric state parameters and regional neutral wind morphology, respectively. The objective is to understand a single event with many measurements and use this event as a representative case.
To accomplish these science objectives, the mission will use two sounding rocket payloads that will launch from Poker Flat Research Range, AK: an instrumented payload (46.031) that will contain a suite of plasma and neutral instrumentation and the vapor tracer payload (36.360). The plan is to launch both payloads within 10 minutes of each other

The Principal Investigator is Dr. Kaeppler/Clemson University.
