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.
Curiosity drilled at Duluth on sol 2057, for the first time in a year and a half. As the rover finished up work at the site with this self-portrait on sol 2082 (15 June 2018), a massive dust storm was encircling the planet.
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.
