    Operations

    Operational Requirements
    UV camera, Spectrometer, Video camera, set of interference filters.

    Operational Protocols
    Conducting radiometric and spectrometric measurements in the UV range: Radiation emitted in reactions of interaction between ISS RS propulsion system exhaust products and atomic oxygen; Radiation emitted in reactions of interaction of Soyuz and Progress propulsion system exhaust products during undocking maneuvers, retroburns and re-entry into the Earth's upper atmosphere; Spacial distribution and emission spectra of atmospheric formations and phenomena.

    Results/More Information
    Determining the effects of propulsion system exhausts on the Earth's upper atmosphere and ISS environment on optically sensitive surfaces (windows, equipment lenses, solar array panels). In perspective, simulation of atmospheric optical phenomena in ultra-violet, visible and near-infrared spectral bands (Earth atmosphere nightglow, SC re-entry glow, planetary atmospheric glow).
