11,12,13,14,15,16,17,18,19/20,21/22Previous ISS Missions
Verification of available discharge current processes on the ISS predicted theoretically.
Detection of dependence of current process intensity in plasma environment of the station upon the ISS configuration, its in-orbit position, operation of external onboard systems and seasonal change in outer space environment by optical radiation characteristics.
Information PendingEarth Applications
UV chamber, spectrometer, videocamera, set of interference filters.Operational Protocols
Verify physical model simulating interaction of plasma sheath with oppositely charged ISS structural members, as well as different types of the ISS RS external coatings. Study space factor impact (geomagnetic field, solar radiation, incoming ionosphere, flows of auroral particles and shocks of micrometeoroids) on initiation, intensity and duration of electric discharge processes.
Electric discharges passing through the ISS plasma environment and caused by high-voltage potential of the USOS solar arrays can produce effects on electric potential of the station body and make changes in operating conditions of electronic equipment placed externally, as well as affect safety of cosmonauts? activities during EVA. This experiment will enable to update the physical model of the ISS plasma environment, adjust operating conditions of hardware, predict unfavorable periods for EVA, as well as make an assessment of a potential negative effect of arising currents on the integrity of the ISS separate structural members.
