Space Experiment OBSTANOVKA

The “Obstanovka-1st stage” will be carried out to provide a databank of electromagnetic fields and of plasma-wave processes occurring in the ISS near-surface zone (NSZ) to account for the influences of the plasma component factors of near-Earth space (NES), including influence of an artificial origin. During November 2005 the integration of engineering model of the PWS will be executed in IKI. In 2006 testing of engineering model of the PWS will be made in RSK "Energia". The realization of experiment on board RS ISS is planned for first half of 2007.

The purposes of the "Obstanovka 1-st stage" experiment are:

FE-1 Lonchakov meanwhile had 90 min. reserved for configuring the GFI-11/ OBSTANOVKA (Environment) equipment in the DC1 Docking Compartment and performing the first electric field measurements with the Langmuir Probe on the external hull of the SM (Service Module). [Field voltages (mV) were scanned cell by cell with the Fluke 105B ScopeMeter oscilloscope, and the oscillograms on the screen recorded by photographing, plus the scanning values were logged in a table. The performance of the ScopeMeter was checked with the Elektronika MMTs-01 MultiMeter. All photographic records were then downlinked via OCA.]
第4章「きぼう」曝露部搭載 宇宙環境計測装置(SEDA-AP)の開発と初期データ(平成21年度宇宙環境利用の展望, JSS)
 宇宙ステーションでのプラズマ計測を現在行っているのは、米国NASA のプラズマ計測装置(FPMU:Floating Potential Meas. Unit)、20082013 年に設置されたロシアのプラズマ計測装置(Obstanovka)に続いて、わずか3 か所の常設の装置となる。サッカー場のサイズの宇宙ステーションは、太陽光の日照中や日陰中にプラズマの中を飛翔する中で様々な電位に帯電するし、ISS の場所によって異なる。宇宙ステーションの太陽電池パドルは160Vの電圧を発生し、マイナス側を接地しているので、宇宙ステーションの本体は、日照中はおよそ-160V から日陰中は約+20V まで地球周回毎に変動するが、宇宙飛行士の船外活動中と、HTV などが宇宙ステーションにドッキング中のみは-40V から+40V の範囲内に帯電電位を人為的(プラズマ・コンタクタ)にコントロールしている。これがうまく作動しないと、放電が起きて、宇宙服のピンホール損傷、ドッキング用の電気コネクタの損傷を招くので、プラズマや電位計測は非常に重要な計測という認識である。

Hungarian instruments on board of the International Space Station Monitoring Space Weather (Élet és Tudomány, LXVII. year 11. number, 2012.03.16)
As seen above, a huge number of instruments have been developed in order to examine the ionosphere. The analysis of our planet and its atmosphere requires global cooperation, and Hungarian researchers participate in it by designing and developing instruments. Proposed by ELTE Research Laboratories, an important research program was accepted to study the relationship between earthquakes and space around the Earth. The team at ELTE presumes that there are changes prior to tectonic movements before seismic processes and earthquakes on the Earth which may affect the orbital space state, and tensions in terrestrial rocks could affect the space around the Earth. These phenomena can be detected and measured in the ionosphere because the Earth can be considered as a cosmic capacitor. Scientific analysis of data provided by the project may forecast earthquakes in a reliable way. When you look up at the sky at night and see the ISS passing through as a luminous object, remember how many fascinating problems can be solved by the onboard instruments!
ISS astronauts to install natural disasters’ forecast system (RUVR, 7 March 2013)
The crew of the new mission to the International Space Station (ISS), during one of its four planned spacewalks, will install a unique equipment for conducting the new experiment, "The Situation", on the outside of the Russian segment of the station. The commander of the crew ISS-36, Pavel Vinogradov told this to reporters. "This is a new, very complex system of sensors and antennas, and the experiment is designed to study the plasma-wave processes in the Earth's upper atmosphere. Eventually, this will benefit the mankind in prediction of earthquakes and about possibility of natural disasters", - said Vinogradov. The new expedition starts on the night of March 29 from Baikonur aboard the "Soyuz TMA-08M".
Spacewalkers Deploy Plasma Experiment, Install Navigational Aid (NASA, 2013.4.19)
The spacewalkers' first task was to install the Obstanovka experiment on the station's Zvezda service module. Obstanovka will study plasma waves and the effect of space weather on Earth's ionosphere.

Expedition 38 Preparing for Mission’s Fourth Spacewalk (NASA, January 15, 2014)
Cosmonaut and veteran station resident Mikhail Tyurin reconfigured communications gear inside the Rassvet mini-research module. He spent the rest of the afternoon setting up sensors to check temperatures and air flows, checking electronics gear and downloading science data collected for the Obstanovka experiment.

    LC ISR is Co-PI of the international experiment OBSTANOVKA-1 onboard the Russian segment of the International Space Station (ISS). The main goal of the experiment is to develop the methodology and instrumentation for EM phenomena investigation in the ISS environment. To fulfil this goal the automatic mini-buoys and necessary operation procedures are under development. Tentative launch date is year 2004.
