The constraints for extraterrestrial missions are quite high in terms of volume, mass, power consumption, radiation resistance and data transmission of the instruments used.In this work, the Dar al Gani 400 meteorite (DAG 400), which was found in 1998 in the respective meteorite field in the Libyan Sahara, is utilized as a model for extraterrestrial research employing M\u00f6ssbauer and Raman spectroscopy. In addition, optical and X-ray microscopic (XRM) investigations were carried out, which provided images of the surface and interior of the meteorite, respectively, and further supported the results. For M\u00f6ssbauer spectroscopy, the miniaturized M\u00f6ssbauer spectrometer MIMOS II, which has already gained recognition in extraterrestrial research on Mars, was employed for phase determination. This finding serves as a crucial demonstration that the miniaturized M\u00f6ssbauer spectrometer MIMOS II is well-suited for future space missions and the analysis of extraterrestrial materials.Notably, this study represents a novel application of M\u00f6ssbauer spectroscopy in the analysis of DAG 400. The present study demonstrates the feasibility of phase assignment through the analysis of DAG 400, and it underscores the potential for further insights through the determination of oxidation states and mineralogical composition. Our work also underscores the pivotal role of multimodal and complementary analytical methodologies in this domain.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ren\u00e9 Gro\u00df, Christoph Wetzel, Lei Zheng, Christoph Kahra, Justus Pawlak, Kevin Tran, Maximilian Seydi Kilic, Harald Gaber, Bernhard Roth, and Franz Renz ACS Earth and Space Chemistry, Publication Date (Web): June 23, 2025 LINK (OPEN&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1598,41,181],"tags":[6874,1827,1857,595,264,270,5192],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/38645"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=38645"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/38645\/revisions"}],"predecessor-version":[{"id":38646,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/38645\/revisions\/38646"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=38645"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=38645"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=38645"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
