The ChemCam Instrument Suite on the Mars Science Laboratory (MSL) Rover: Body Unit and Combined System Tests

Wiens, Roger; Kirkland, L. E. (Laurel Ellyn) (Springer, 2012-06-21)

The ChemCam instrument suite on the Mars Science Laboratory (MSL) rover Curiosity provides remote compositional information using the first laser-induced breakdown spectrometer (LIBS) on a planetary mission, and provides ...
Geochemical variation in the Stimson formation of Gale crater: Provenance, mineral sorting, and a comparison with modern Martian dunes

Bedford, Candice; https://orcid.org/0000-0002-0783-1064; Schwenzer, Susanne Petra; Bridges, John C.; Banham, Steven; Wiens, Roger; Gasnault, Olivier M.; Rampe, Elizabeth; Frydenvang, Jens; Gasda, Patrick J.; https://orcid.org/0000-0002-9608-0759 (Elsevier, 2020-05)

A ChemCam geochemical study of the ancient aeolian Stimson formation in Gale crater. The geochemical effect of mineral sorting in the ancient dunes has been preserved. The Stimson dunes were transported SW-NE, opposite to ...
The importance of the study of igneous rocks and compositions to constrain the Martian planetary evolution.

Udry, Arya; Filiberto, Justin; https://orcid.org/0000-0001-5058-1905; Gross, Juliane; Schmidt, Mariek E.; Rogers, Deanne; Hausrath, Libby; Wiens, Roger; Lanza, Nina (2020-07)

This white paper summarizes the scientific importance of studying igneous compositions in meteorites, surface samples, and through orbital analyses to better constrain the geology of Mars as a whole and better understand ...
Origin and composition of three heterolithic boulder- and cobble-bearing deposits overlying the Murray and Stimson formations, Gale Crater, Mars

Wiens, Roger; Edgett, Kenneth S.; Stack, Kathryn M.; Dietrich, William E.; Bryk, Alexander B.; Mangold, Nicolas; Bedford, Candice; https://orcid.org/0000-0002-0783-1064; Gasda, Patrick J.; Fairén, Alberto G.; Thompson, Lucy; Johnson, Jeff; Gasnault, Olivier M.; Clegg, Sam; Cousin, Agnes; Fornij, Olivier; Frydenvang, Jens; Lanza, Nina; Maurice, Sylvestre; Newsom, Horton E.; Ollila, Ann; Payré, Valerie; Rivera-Hernandez, Frances; Vasavada, Ashwin (Elsevier, 2020-06-06)

Here we present ground-based observations regarding a puzzling type of geological unit first observed prior to landing. Using ~25 cm/pixel High Resolution Imaging Science Experiment (HiRISE; McEwen et al., 2007) images ...
