Abstract : The TOROID II small satellite mission has been developed by faculty and students at Utah State University (USU) to measure vertical density profiles of the night time ionospheric plasma density distribution. Measurements will be achieved by using a tomographic reconstruction of extreme ultraviolet (EUV) night glow in the 1356 Angstrom emission band. The mission will focus on the Equatorial Anomaly regions, where the highest ionospheric plasma densities are observed and where equatorial plasma bubbles are observed to occur. In order to achieve the TOROID II mission all spacecraft systems including satellite communication system, the navigation, Attitude determination and control, thermal must function within the Sun-Earth space environment. The science instrumentation for this mission will be accomplished using both a Sweeping Plasma Impedance Probe to measure local densities, as well as a EUV Photometer to measure night glow.
