Depositional History of the Otis Peak Formation, Western Fan, Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The Mars 2020 Perseverance rover mission spent ∼250 sols investigating the Otis Peak formation (OPfm), a sequence of rocks containing the youngest recorded interval of sediment deposition via aqueous activity on Jezero crater’s western fan. This study uses orbiter and rover observations to interpret the formation and emplacement history of the

Photometric Characterization of the Moon's Silicic Sites: Insights Into the Origin of Silica‐Rich Magmas

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Lunar “red spots” have been inferred to be regions of extrusive silicic volcanism based on the analysis of remote sensing observations that suggest SiO2 ${\mathrm{S}\mathrm{i}\mathrm{O}}_{2}$‐rich, FeO‐poor composition and morphologies similar to terrestrial silicic domes.

Active Neutron Spectroscopy to Determine the Hydration of Low‐Mass, Sealed Mars Samples

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Mars samples returned to Earth as part of the NASA Mars Sample Return program (MSR) will be subject to a wide range of scientific analyses, many of which will have important implications for the search for life/habitability and planetary evolution. Critical to both of these is the hydration state of the samples. But to ensure the most accurate

An Analysis of the Recent Global Geologic History of Europa: Evidence for Clustered Resurfacing and a Lack of True Polar Wander

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Global geologic mapping shows that Europa’s surface is made up of an array of features including extensive ridged plains, regions of broad disruption termed chaos terrain, quasi‐linear ridges that span thousands of km, and bands up to 60 km wide that extend for 100–1000s of km.

Laboratory Experiments Identify Meteoritic Organic Precursors for Chlorinated Compounds Detected by the Sample Analysis at Mars (SAM) Instrument at Gale Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The Viking missions landed two spacecraft on Mars each equipped with a pyrolysis‐gas chromatograph‐mass spectrometer system capable of detecting signs of life. Although working as intended, detections of chloromethane and dichloromethane were initially attributed to terrestrial contamination.

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, Volume 40, Issue 11, Page 3398-3421, November 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Contrasting associations between parental coordination and breeding success in albatrosses across differing environmental contexts

Journal of Animal Ecology, Volume 95, Issue 11, Page 2306-2321, November 2026.
Our study demonstrates that the benefits of parental coordination in albatrosses are context‐dependent rather than universal. Coordinated parental care enhanced reproductive success in stable environments, but had little effect in variable environments, where individual flexibility may be more valuable.

Multi‐Response Optimization of Formulation and Processing Parameters for a High‐Protein Beef‐Based Snack to Enhance Mechanical Crispiness, Acoustic Crispiness, and Protein Digestibility

Journal of Food Science, Volume 91, Issue 11, November 2026.
ABSTRACT This study aimed to optimize the formulation and processing parameters of beef‐based chips to maximize textural properties and protein digestibility using response surface methodology (RSM) with a central composite design. Statistical models were developed to predict the effects of beef powder incorporation level (%), extruded sheet thickness (

Virtual Reality Control of a Planetary Rover Manipulator Using Unity and Unreal Engine

Applications of Modelling and Simulation
This paper presents a method for controlling a manipulator mounted on a planetary rover using virtual reality (VR) technology. The proposed approach combines VR controllers with stereovision cameras to provide the operator with an improved view of the ...
