Stratigraphy Preserved on the Jezero Crater Rim Reveals Repeated Impacts on Early Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The outer slopes of the western Jezero crater rim are hypothesized to expose sections of Early‐ to Pre‐Noachian crust uplifted by the Jezero impact, providing an excellent opportunity to investigate the earliest geologic processes active on terrestrial planets.

Degradation of Rustic Canyon Crater in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract The Rustic Canyon crater is a degraded impact structure on Mt. Sharp in Gale crater. The crater is irregular in plan form, ∼20 m across NW‐SE and ∼30 m across NE‐SW and lacks a raised rim. Using images and a Digital Terrain Model derived from a rover orthomosaic of the crater, we evaluated the amount and processes of degradation based on ...

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

The Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

Quels savoirs économiques pour informer l’action internationale pour la biodiversité ? Questionnements épistémologiques à partir de l’exemple de la priorisation spatiale

Global Africa
La perte de biodiversité et d’habitats naturels s’accélère à l’échelle mondiale. Face à ce constat, la recherche en économie mobilise, entre autres, des outils de priorisation spatiale afin d’orienter les efforts de restauration et de conservation.

Segregation, Spatial (In)Justice, and the City [PDF]

Berkeley Planning Journal, 2011
Segregation has been widely discussed by social scientists and especially by urban geographers and planners over the past decades. However, regardless of their focus, most of these studies view segregation as an obvious case of spatial injustice. I argue that this implicit relationship between segregation, (in)justice, and space needs to be reexamined.

To Which Extent the Surface Water Ocean Topography (SWOT) Mission Is Currently Able to Monitor Water Surface Elevation and Extent on the French Lakes?

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study (July 2023–December 2025) assesses the SWOT satellite's ability to measure water surface elevation (WSE) and surface water extent (SWE) over diverse French lakes. WSE estimates from SWOT were compared to in situ gauge data and conventional radar altimetry, while SWE was evaluated using the Global Water Watch (GWW) database.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.
