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.
