Terrestrial Mineral Analysis by Remote Sensing

The T-MARS 2020-2023 project, funded by the Canadian Space Agency, is conducted by a team of researchers and students from Université de Sherbrooke and McGill University, the Geological Survey of Canada and ELEMSSION.

This project aims to study the composition of gossans in the Canadian Arctic as analogous to potentially similar geological formations on the planet Mars. More details about the project...

The T-MARS project will also train highly qualified personnel (HQP) in the fields of geomatics, remote sensing, astrobiology and geology by providing hands-on experience to students at various levels. More details about the training of our HQPs...

Our region of study and fieldwork: the Canadian Arctic

The geological formations studied by the T-MARS team are the gossans, which result from the oxidation of sulphide deposits by acidic fluids. These formations contain alteration minerals (e.g. gypsum, jarosite, hematite) that are also found on Mars. Gossans are visible on satellite images, usually in the form of oxidized ochre-coloured formations. More details about gossans...

The arid climate of the Canadian Arctic slows down alteration processes, which allows the conservation of certain minerals such as jarosite that would degrade in a hot and humid climate. Since jarosite is an indicator of the habitable potential of Mars, the Arctic region is a prime location to study gossans, which are formed by processes similar to those that shaped the surface of Mars.

The T-MARS field team, composed of researchers and students, will visit Axel Heiberg Island in July 2021 and 2022 to collect remote sensing data and samples. These will then be used by the M.Sc. students in the realization of their research project. This field experience will allow the students to develop skills in the realization of an applied remote sensing project, from the definition of the project to the acquisition, processing and analysis of the data. More details about the field work...

The agency’s latest and most complex mission to the Red Planet has touched down at Jezero Crater. Now it’s time to begin testing the health of the rover. The largest, most advanced rover NASA has sent to another world touched down on Mars Thursday, February 18, 2021, after a 203-day journey traversing 293 million miles (472 million kilometers). Con...
