USED SCIENCE HARDWARE:
Spectrozonal ultraviolet system Fialka-MV-Kosmos,
- UV chamber;
- set of interference filters.
- Video cassettes mini-DV;
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.
- Verification of 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 of 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 cosmonautsí
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.
3,5"-diskettes with the recorded radiation
video cassettes mini-DV with the recorded phenomenon
ballistic data (ISS orientation, ISS altitude, geographic
coordinates of subsatellite point, Sun and Moon angles)
for referencing the measurement results.
