planetary terrestrial analogues library

The European Space Agency has collaborated with numerous museums and university geological departments to curate a collection of rocks and minerals, BLDG Blog reports, as a heuristic tool for future exploration, reasoning out properties of extra terrestrial surfaces and strata by relating it to more mundane and familiar correspondents.
Jarosite, for example, is a rare volcanic rock that is testament to the presence of water on Earth and was found on Mars early on before any evidence of water had been discovered. The growing catalogue of space-prospectors consists of around forty-five hundred known Earth minerals, complimented with three hundred isolated from meteorites, one hundred thirty from the Moon and about eighty Martian samples.
