Learn about SISTINE missions with 5 min suborbital flight in Summer 2022 with Far UV imaging spectroscopy imaging 100k photons at 100 to 160 nm for emission lines associated with atmospheres of low mass stars and exoplanets. With advanced optical mechanical designs, this enables SISTINE to achieve high signal-to-noise observations of emission lines from planet-hosting dwarf stars with moderate spectral resolution (R ~ 10,000) and sub-arcsecond angular imaging. Topics include: exoplanet atmospheres, borosilicate microchannel plate detectors, al coating mirror, 1200lb mass, Alfvén waves , alpha centauri, UV Flux, atomic oxygen, and significance for discovering habitable exoplanets
