SwRI's ISpec instrument for the ISCEA observatory: design

The ISCEA observatory is a small satellite with a mass of under 150kg. SwRI's ISCEA near-infrared (NIR) spectrograph instrument (ISpec) with parallel imaging and multi-object spectroscopy channels is designed to meet the ISCEA observatory science goal: to determine the history of star formation and its quenching in galaxies as a function of local density and stellar mass when the Universe was 3-5 Gyrs old (1.2 1000; >300 simultaneous object spectral acquisition; 2.8"x 2.8" "slit" size; emission line flux limit (5-sigma) of 3x10(-17) erg/s/cm(2); field of view of >= 0.27 deg(2); and throughput >= 0.2.
