OBJECTIVE:
Investigation of chemiluminescent chemical reactions
and atmospheric optical phenomena occurring during
high-speed interaction between jet engine exhausts
and the Earth's upper atmosphere, atmospheric optical
phenomena during re-entry of bodies into rarified
upper atmosphere and its optical properties in the
UV range.
TASKS:
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.
EXPECTED RESULTS:
Determining the effects of propulsion system exhausts
on the Earth 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).
