UV Raman spectroscopy—A technique for biological and mineralogical in situ planetary studies
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2007We report on the great advantages of using deep UV Raman system for in situ planetary applications. Among them are to be mentioned: (I) higher scattering efficiency compared to VIS-IR Raman excitation wavelengths, (II) electronic resonance effects which increase the intrinsically weak Raman signal thus improving the S/N ratio of the detected Raman ...

Mineralogical study of proto-planetary disks in FU Orionis stars
Proceedings of the International Astronomical Union, 2009AbstractWe report on mid-infrared (8–13 μm) spectroscopic observations of eight FU Orionis type objects and discuss a qualitative initial mineralogical analysis.

Optical design of a compact imaging spectrometer for planetary mineralogy
Optical Engineering, 2007We present the design of a compact, wide-angle pushbroom imaging spectrometer suitable for exploration of solar system bodies from low orbit. The spectrometer is based on a single detector array with a broadband response that covers the range 400 to 3000 nm and pro- vides a spectral sampling of 10 nm.

Abstract The importance of the discovery of jarosite at the Meridiani Planum region of Mars is discussed. Terrestrial studies demonstrate that jarosite requires a unique environment for its formation, crystallizing from highly acidic (pH 2 that reacted with aqueous solutions in shallow aquifers or on the martian surface. This interaction forms both

The Ultra-Compact Imaging Spectrometer (UCIS) is a miniature telescope and spectrometer system intended for mapping terrain mineralogy over distances from 1.5 m to infinity with spatial sampling of 1.35 mrad over a 30° field, and spectral sampling of 10 nm in the 600-2500 nm range.

From the underground to the stars. The project for a new planetary and mineralogical museum in Prato
2022The Museum of Planetary Sciences in Prato (MSP), founded in 2005 and managed since 2017 by Fondazione PARSEC (FP), houses more than 500 meteorites and about 7000 mineralogical samples – some of which are rare and of great value, because they come from Tuscan mines or mining localities that are now abandoned or no longer accessible.

El reciente descubrimiento de minerales hidratados sobre la superficie de Marte sugiere la presencia de importantes cantidades de agua líquida durante algunas etapas de su historia geológica. A raíz de este hallazgo, los estudios sobre minerales hidratados en ambientes terrestres como potenciales análogos marcianos han adquirido gran relevancia.

American Mineralogist, 2004
As our contribution to the new "Oxygen in the Solar System" initiative of the Lunar and Planetary Institute and the NASA Cosmochemistry Program, we have been developing oxygen barometers based largely on behavior of V which can occur in four valence states V2+, V3+, V4+, and V5+, and record at least 8 orders of magnitude of fO2.

Investigating Planetary Core Formation with Geophysical Modeling and High-Pressure Mineralogy
2022Earth’s core is impossible to sample or directly observe and yet is fundamentally important to the properties of, and our continued existence on, this planet. Indeed, planetary cores literally underlie every other area of geoscientific inquiry, and core properties controlled the development of Earth, Mars, and likely every other terrestrial planet.
