Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

A. Ollila, Olivier Beyssac, A. Fau, O. Forni et autres

Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks. …

SuperCam Chlorine Detections on the Jezero Crater Floor

Z. U. Wolf, Gorka Arana, Juan Manuel Madariaga, S. Clegg et autres

Volatiles, such as chlorine (Cl), are important species that are easily mobilized by fluids and thus play a key role in alteration processes on Mars [1]. The first detections of Cl were made in the 1970’s by the Viking 1 & 2 …

Intense alteration on early Mars revealed by high-aluminum rocks at Jezero crater

Clément Royer, C. C. Bedford, J. R. Johnson, B. Horgan et autres

abundances suggests heating-induced dehydration which could have occurred during the lithification or impact excavation of these rocks. Given the orbital context of kaolinite-bearing megabreccia in the Jezero crater rim, we propose an origin for these rocks involving intense aqueous alteration of the …

Assessing the Effects of Virtual Cue Implementation in Virtual Reality Welding Training

Brittney Heibel, R. B. Anderson, Marshall Swafford, Bradley Borges

Incorporating virtual reality (VR) technology into training environments has proven effective because it allows training to remain safe, efficient, and meaningful. Welding training is no exception, with research exhibiting benefits such as decreased welder anxiety, increased cost- and time-efficiency, reduction in material …

Radiation-induced alteration of apatite on the surface of Mars: first in situ observations with SuperCam Raman onboard Perseverance

Elise Clavé, Sylvain Bernard, Susanne Schröder, Kristin Rammelkamp et autres

Planetary exploration relies considerably on mineral characterization to advance our understanding of the solar system, the planets and their evolution. Thus, we must understand past and present processes that can alter materials exposed on the surface, affecting space mission data. Here, we …

Manganese‐Rich Sandstones as an Indicator of Ancient Oxic Lake Water Conditions in Gale Crater, Mars

P. J. Gasda, N. Lanza, Pierre‐Yves Meslin, Sarah Lamm et autres

Abstract Manganese has been observed on Mars by the NASA Curiosity rover in a variety of contexts and is an important indicator of redox processes in hydrologic systems on Earth. Within the Murray formation, an ancient primarily fine‐grained lacustrine sedimentary deposit in …

Integrating virtual reality technology into beginning welder training sequences

Brittney Heibel, R. B. Anderson, Marshall Swafford, Bradley Borges

Virtual reality (VR) technology is an advanced modern resource commonly integrated into various forms of training. VR training simulations are customizable in that quality-grading parameter settings, physical environment, and user capacity can be modified to personal or professional preference. In this study, …
