“…Further development of Mössbauer spectrometers led to appearance of new possibilities in its applications. For example, the miniaturized Mössbauer spectrometer MIMOS II was developed by Göstar Klingelhöfer (1956Klingelhöfer ( -2019 and his team for the exploration of planetary surfaces (see [18] and references therein), the two of which were successfully used for the 2003 NASA (USA) Mars missions (for review see [19][20][21]). Mössbauer spectroscopy based on synchrotron radiation became a useful, precise, and fast instrument in the study of materials (see, e.g., [22,23]), which was applied for meteorite studies.…”

Mössbauer (nuclear γ-resonance) spectroscopy is a powerful technique which is actively used in various fields from physics and chemistry to biology and medicine. Rudolf L. Mössbauer, who observed nuclear γ-resonance and published his results in 1958, got a Nobel Prize in physics in 1961 for this discovery. 57Fe is the most widely used nucleus in Mössbauer spectroscopy. Therefore, a large variety of compounds containing iron can be studied by Mössbauer spectroscopy. It is well known that planetary matter contains various iron-bearing phases and minerals. Therefore, the extraterrestrial material from different meteorites, asteroids, and planets can be studied using 57Fe Mössbauer spectroscopy as an additional powerful technique. Two parts of this review consider the results of more than 50 years of experience of Mössbauer spectroscopy applied for the studies of various meteorites, soils, and rocks from the Moon and a recent investigation of the Martian surface using two rovers equipped with miniaturized Mössbauer spectrometers. Part I considered the results of Mössbauer spectroscopy of undifferentiated meteorites. Part II discusses the results of Mössbauer spectroscopy of differentiated meteorites formed in asteroids and protoplanets due to matter differentiation, as well as Lunar and Martian matter.

“…There are different metal grains in Isheyevo with variations in Ni content (4.2-14.3 wt.%, >25 wt.%) [34]. Based on these data and using the H eff values, the revealed magnetic spectral components for both internal and external parts can be related to the following metal phases: the α 2 -Fe(Ni, Co) phase (1 and 2), the α-Fe(Ni, Co) phase (3)(4)(5), and the γ-Fe(Ni, Co) phase (6)(7)(8). The presence of several magnetic sextets for one phase was also explained as a result of variations in Ni content within one phase.…”

“…These iron-bearing compounds have been studied using 57 Fe Mössbauer spectroscopy since the Mössbauer effect was discovered and the method of γ-resonance spectroscopy was developed (see for review [2,3]). Further development of this technique provides new possibilities in the study of meteorites, e.g., conversion electron Mössbauer spectroscopy (CEMS) and other backscattering Mössbauer techniques permit the surface investigation (e.g., [4,5]), synchrotron Mössbauer spectroscopy allows one to study the areas with high spatial resolution (e.g., [6,7]), and Mössbauer spectroscopy with a high velocity resolution allows for the detailed study of complex materials which represent various meteorites (see [8][9][10][11][12]). In the latter case, a high velocity resolution means a high discretization of the velocity reference signal formed by the digital-analog converter (2 12 or 4096 steps) [13][14][15][16], while conventional Mössbauer spectrometers usually use discretization of 2 8 or 2 9 .…”

Meteorites are the space messengers bringing us the unique information about the Solar System formation and evolution as well as about the effects of various extreme space conditions on meteorites and their parent bodies. The main iron-bearing compounds in meteorites are Fe-Ni-Co alloy, olivine (Fe, Mg)2SiO4, orthopyroxene (Fe, Mg)SiO3, clinopyroxene (Ca, Fe, Mg)SiO3, troilite FeS, chromite FeCr2O4, hercynite FeAl2O4, ilmenite FeTiO3, daubréelite FeCr2S4, schreibersite (Fe, Ni)3P and some other compounds. Therefore, 57Fe Mössbauer spectroscopy was successfully applied for the analyses of various meteorites for about 60 years of experience. The development of Mössbauer spectrometers with a high velocity resolution, i.e., with a high discretization of the velocity reference signal up to 212, provides much better adjustment to resonance and significantly increases the spectra quality and analytical possibilities of Mössbauer spectroscopy. In fact, this permits us to decompose the complex Mössbauer spectra of meteorites using the larger number of spectral components related to reliable compounds in comparison with the results obtained using conventional Mössbauer spectrometers with discretization of the velocity reference signal up to 29. In the present review we consider the results and advances of various meteorites analyses by means of Mössbauer spectroscopy with a high velocity resolution.

“…The study of the surface of Mars by means of Mössbauer spectroscopy became possible with development of the miniaturized spectrometer MIMOS II (see [133][134][135]). Two robotic rovers of NASA's Mars Exploration Rover Missions named Spirit and Opportunity were equipped with MIMOS II spectrometers that recorded the backscattered Mössbauer spectra of the surface targets.…”

Part I will discuss known results on Mössbauer spectroscopy of undifferentiated meteorites, which are the most primitive and formed with the solar system.
