Geophysics research on ISS Russian Segment
Obstanovka Experiment
Objective:
Organization and support of ecological low-frequency electromagnetic monitoring of environmental disturbances based upon facilities and hardware; taking plasma-wave measurements onboard the ISS under basic research programs devoted to Sun-Earth relations in the most active ionospheric area - F2 layer.
Generation of experimental database on Earth ionospheric electromagnetic state in order to detect and prevent its disastrous changes.
Tasks:
- Determining spectral density of electromagnetic, electrostatic and magnetic fields in the frequency range from a fraction of Hz to tens of megaHz in the stage of single-axis measurements on exposure to different orbital flight factors, including effects of artificial origin.
- Measurements of Earth magnetic field intensity vectors along flight course.
- Determining plasma particles flow density fluctuation spectra.
Scientific equipment in use:
Plasma-wave complex (PWC).
PWC complex incorporates KVD1 and KVD2 units attached to adapters and a set of sensors accommodated on two collapsible rods, as well as telemetry information storage unit (TISU) with replaceable recorder unit (RRU).
Expected results:
Study of the problem of ensured long-term sustained operation of superlarge SC in orbit by analyzing sufficiently large quantity of accumulated full-scale experimental data on electromagnetic environment (EME).
Experiment Results:
Service and scientific TMI downlinked to the ground over ÁÈÒÑ 2-12 channels, as well as recorded on ÁÑÏÍ hard disk and replaceable recorder unit (RRU).
