ALERA‐V Version 1.0: An Objective Analysis Dataset of the Venus Atmosphere

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
Using observations from the Venus orbiter Akatsuki, we present the first objective analysis dataset of the Venus atmosphere. ALERA‐V, generated with the ALEDAS‐V system using the LETKF, is expected to support studies of atmospheric dynamics and the planning of future satellite missions.

Design of Low-Altitude Martian Orbits using Frequency Analysis

, 2021
International audienceNearly-circular Frozen Orbits (FOs) around axisymmetric bodies-or, quasi-circular Periodic Orbits (POs) around non-axisymmetric bodies-are of primary concern in the design of low-altitude survey missions.

Resultant Force on Grains of a Real Sand Dune: How to Measure It?

Geophysical Research Letters
Barchan dunes usually appear under the action of one‐directional fluid flows, being found on Earth, Mars, and other celestial bodies; however, although ubiquitous in nature, understanding dune dynamics at the grain scale is challenging due to the vast ...

(Dis)information Systems: a Systemic View of Disinformation

Systems Research and Behavioral Science, Volume 43, Issue 4, Page 1560-1575, July/August 2026.
ABSTRACT Disinformation is an ancient social phenomenon that has found a favourable environment for dissemination in internet‐based social networks. While the scientific community seeks to address the problem by creating specific tools to detect and classify the various types of false information, we argue that systems thinking is necessary to ...

Formation of Compact Aggregate Piles on a Surface Through Dissipation of Kinetic Energy Associated With Horizontal Motion

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Accumulation of dust on the Lunar and Martian surfaces plays a critical role in both surface evolution and human exploration efforts, limiting equipment lifetimes and obscuring optical surfaces. Yet, the underlying physics of surface soiling is still poorly understood.
