The history of the project

Formation of the scientific objectives of the project "Ionosat - Micro" was for a long time, and conceptual provisions were first formulated in the 1990s, during the development of unrealized mission "Warning." Then, after tragic Spitakskii earthquake (1988), the political leadership of the USSR initiated the development of new, more effective methods of earthquake prediction, based, in particular, on the use of non-traditional for Seismology approaches such as observation of ionospheric harbingers of earthquakes etc. Thus arose the idea of mission "Warning", which, if not collapse of the USSR (1991), could be the most ambitious satellite project in the history of world studies of the ionosphere. The "Ionosat-Micro" Mission on the satellite "Mikrosat-M" embodies the ideas of the mission "Warning" on modern scientific and technological basis.[3][4]

For the diagnosis of electromagnetic processes in ionospheric plasma in the "Ionosat-Micro" Mission will be used complex instrument MWC, developed by Lviv Centre of Space Research Institute. Experimental testing elements MWC was conducted space experiments "Variant" in the Ukrainian remote sensing satellite "Sich-1M" (2004).[5] To measure the parameters of the ionosphere gas - concentration and temperature neutral and ionized gases - is a complex instrument DN - DE, established in Institute of Technical Mechanics. Flight testing sensors DN and DE experiment was carried out in "Potential" in the Ukrainian remote sensing satellite Sich-2 (2012).[6] In the "Ionosat-Micro" Mission involving foreign partners: Research Center is instrument RFA creator and Space Research and Technology Institute is instrument ID-2 creator.

The satellite launch was planned for 2018. As of May 2019, work is go on.[7]

gollark: First-past-the-post is the simplest and most obvious thing you're likely to imagine if you want people to "vote for things", and it's entirely possible people didn't look too hard.
gollark: I don't know if the people designing electoral systems actually did think of voting systems which are popular now and discard them, but it's not *that* much of a reason to not adopt new ones.
gollark: There are plenty of things in, say, maths, which could have been thought up ages ago, and seem stupidly obvious now, but weren't. Such as modern place value notation.
gollark: Obvious things now may just not have been then.
gollark: Hindsight bias exists.
