Thomas Appéré is an associate scientist at L’IPAG, l’Institut de Planétologie et d’Astrophysique de Grenoble (IPAG) in Grenoble, France, and a middle/high school physics and chemistry teacher at Jeanne d'Arc institution in Vitré, France. He holds a Ph.D. in Planetary Sciences and was formerly a post-doc at Laboratoire AIM(CEA-Saclay, France).
His research topic is the exploration of planetary surfaces with remote sensing. He studies the seasonal processes on Mars with OMEGA and CRISM hyperspectral images, focussing on the role of seasonal water ice deposits in the present martian water cycle. He also works on the massive inversion of VIMS observations of Titan.
This mosaic is composed of images acquired by Curiosity's left navigation camera (Navcam) on sol 1833 (October 2, 2017), patched with images from sol 1834. The sky has been digitally expanded to fill the frame.
The Remote Micro Imager, part of the ChemCam instrument, imaged the outcrops of Vera Rubin Ridge on sol 1745 (4 July 2017). The left image was taken by the MastCam 100mm camera at 13:27 local time. The right images were processed using the technique of pansharpening, i.e. the fusion of higher-resolution RMI mosaics with the lower-resolution color MastCam 100mm image, providing colors. The RMI images were taken at 14:32 (bottom) and 14:55 (top) local time.
