Orbital and in-situ investigation of periodic bedrock ridges in Glen Torridon, Gale Crater, Mars Orbital and in-situ investigation of periodic bedrock ridges in Glen Torridon, Gale Crater, Mars
Wind has been the dominant agent of landscape modification on Mars for the past ~3 billion years. Among the diversity of features formed by aeolian abrasion on the surface of Mars are periodic bedrock ridges (PBRs), a relatively recently recognized class of erosional bedforms on Mars for which Earth analogues are rare. Gale crater, the field site for NASA’s Mars Science Laboratory...

Bedrock geochemistry and alteration history of the clay-bearing Glen Torridon region of Gale crater, Mars Bedrock geochemistry and alteration history of the clay-bearing Glen Torridon region of Gale crater, Mars
Glen Torridon is a topographic trough located on the slope of Aeolis Mons, Gale crater, Mars. It corresponds to what was previously referred to as the “clay-bearing unit”, due to the relatively strong spectral signatures of clay minerals (mainly ferric smectites) detected from orbit. Starting in January 2019, the Curiosity rover explored Glen Torridon for more than 700 sols (Martian days...

Diagenesis of Vera Rubin ridge, Gale crater, Mars from Mastcam multispectral images Diagenesis of Vera Rubin ridge, Gale crater, Mars from Mastcam multispectral images
Images from the Mars Science Laboratory (MSL) mission of lacustrine sedimentary rocks of Vera Rubin ridge on “Mt. Sharp” in Gale crater, Mars, have shown stark color variations from red to purple to gray. These color differences crosscut stratigraphy and are likely due to diagenetic alteration of the sediments after deposition. However, the chemistry and timing of these fluid...

Temperatures of the Lacus Mortis region of the Moon Temperatures of the Lacus Mortis region of the Moon
Over 11 years of data acquired by the Diviner Lunar Radiometer Experiment instrument aboard Lunar Reconnaissance Orbiter have been compiled into a comprehensive data set of surface temperatures in the Lacus Mortis region which includes the landing ellipse of the Astrobotic Mission One lander mission. These data provide diurnal brightness temperatures at 128 pixels per degree (ppd)...

Brine-driven destruction of clay minerals in Gale crater, Mars Brine-driven destruction of clay minerals in Gale crater, Mars
Mars’ sedimentary rock record preserves information on geological (and potential astrobiological) processes that occurred on the planet billions of years ago. The Curiosity rover is exploring the lower reaches of Mount Sharp, in Gale crater on Mars. A traverse from Vera Rubin ridge to Glen Torridon has allowed Curiosity to examine a lateral transect of rock strata laid down in a martian...

The Preventing Harassment in Science workshop: Summary and best practices for planetary science and astrobiology The Preventing Harassment in Science workshop: Summary and best practices for planetary science and astrobiology
The NASA-funded Preventing Harassment in Science workshop took place in June of 2020. Here we describe the workshop and summarize the best practices for reducing harassment that were discussed. We include a list of recommendations that can be used to take steps towards reducing harassment in the planetary science and astrobiology community.

Diagenesis revealed by fine-scale features at Vera Rubin ridge, Gale crater, Mars Diagenesis revealed by fine-scale features at Vera Rubin ridge, Gale crater, Mars
Fine-scale (submillimeter to centimeter) depositional and diagenetic features encountered during the Curiosity rover's traverse in Gale crater provide a means to understand the geologic history of Vera Rubin ridge (VRR). VRR is a topographically high feature on the lower north slope of Aeolis Mons, a 5-km high stratified mound within Gale crater. We use high-spatial resolution images...

Extraformational sediment recycling on Mars Extraformational sediment recycling on Mars
Extraformational sediment recycling (old sedimentary rock to new sedimentary rock) is a fundamental aspect of Earth’s geological record; tectonism exposes sedimentary rock, whereupon it is weathered and eroded to form new sediment that later becomes lithified. On Mars, tectonism has been minor, but two decades of orbiter instrument–based studies show that some sedimentary rocks...

Evidence for a diagenetic origin of Vera Rubin Ridge, Gale Crater, Mars: Summary and synthesis of Curiosity's exploration campaign Evidence for a diagenetic origin of Vera Rubin Ridge, Gale Crater, Mars: Summary and synthesis of Curiosity's exploration campaign
This paper provides an overview of the Curiosity rover's exploration at Vera Rubin ridge (VRR) and summarizes the science results. VRR is a distinct geomorphic feature on lower Aeolis Mons (informally known as Mount Sharp) that was identified in orbital data based on its distinct texture, topographic expression, and association with a hematite spectral signature. Curiosity conducted...

A lacustrine paleoenvironment recorded at Vera Rubin ridge, Gale crater: Overview of the sedimentology and stratigraphy observed by the Mars Science Laboratory Curiosity rover A lacustrine paleoenvironment recorded at Vera Rubin ridge, Gale crater: Overview of the sedimentology and stratigraphy observed by the Mars Science Laboratory Curiosity rover
For ~500 Martian solar days (sols), the Mars Science Laboratory team explored Vera Rubin ridge (VRR), a topographic feature on the northwest slope of Aeolis Mons. Here we review the sedimentary facies and stratigraphy observed during sols 1,800–2,300, covering more than 100 m of stratigraphic thickness. Curiosity's traverse includes two transects across the ridge, which enables...

Applied lunar science on Artemis III in support of in situ resource utilization Applied lunar science on Artemis III in support of in situ resource utilization
The Artemis Science Goals and Strategy are focused on basic or fundamental science, neglecting the vital field of “applied” geoscience that fits between “pure” science and engineering to provide near-term practical benefits for human activities.

The thermophysical properties of the Bagnold Dunes, Mars: Ground truthing orbital data The thermophysical properties of the Bagnold Dunes, Mars: Ground truthing orbital data
We compare the thermophysical properties and particle sizes derived from the Mars Science Laboratory rover's Ground Temperature Sensor of the Bagnold dunes, specifically Namib dune, to those derived orbitally from Thermal Emission Imaging System, ultimately linking these measurements to ground truth particle sizes determined from Mars Hand Lens Imager images. In general, we find that all...
