It is with deep sorrow that our research group received the news of the passing of our former colleague Antonio Sansano. Antonio was, for many years, one the supports of Exomars project at the University of Valladolid, and one of our fellow researchers. Last monday, at age 47, Antonio passed away in Valladolid. Last years […]

We evaluated the effectiveness of the ExoMars Raman laser spectrometer (RLS) to determine the degree of serpentinization of olivine-rich units on Mars. We selected terrestrial analogs of martian ultramafic rocks from the Leka Ophiolite Complex (LOC) and analyzed them with both laboratory and flight-like analytical instruments. We first studied the mineralogical composition of the samples

SuperCam is a highly integrated remote-sensing instrumental suite for NASA’s Mars 2020 mission. It consists of a co-aligned combination of Laser-Induced Breakdown Spectroscopy (LIBS), Time-Resolved Raman and Luminescence (TRR/L), Visible and Infrared Spectroscopy (VISIR), together with sound recording (MIC) and high-magnification imaging techniques (RMI). They provide information on the mineralogy, geochemistry andmineral context around the

Aurelio Sanz‐Arranz, Jose A. Manrique‐Martinez, Jesus Medina‐Garcia, Fernando Rull‐Perez In this paper, our research group proposes a simple solution to a usual problem that appears in the Raman analysis of some substances, which is the presence of weak Raman signals, probably in combination with a high‐intensity luminescence background, affected by the presence of distortions in

Between April 24 and 26, 2018, the Erica research group -led by prof. Fernando Rull- attended the mars sample return conference (MSRC), an international congress organized in Berlin (Germany) by ESA (European space agency), NASA (National Aeronautics and Space Administration) and DLR (German Aerospace Center). At MSRC, some of the main experts in the field
