Topics in Cognitive Science, EarlyView.Abstract People's choices of food and drink, the attitudes they express, and the beliefs that they state are influenced by their political and other identities. At the same time, people's everyday choices depend on the context of available options in ways that are difficult to explain in terms of the choosers’ preferences and beliefs.

Saltation under Martian Gravity and its Influence on the Global Dust Distribution [PDF]
, 2018 Dust and sand motion are a common sight on Mars. Understanding the interaction of atmosphere and Martian soil is fundamental to describe the planet's weather, climate and surface morphology. We set up a wind tunnel to study the lift of a mixture between very fine sand and dust in a Mars simulant soil.

Mapping Water on the Moon and Mars using a Muon Tomograph [PDF]
arXiv, 2023 The search for water on the Lunar and Martian surfaces is a fundamental aspect of space exploration, contributing to the understanding of the history and evolution of these celestial bodies. However, the current understanding of the distribution, concentration, origin, and migration of water on these surfaces is limited.

Women in space: A review of known physiological adaptations and health perspectives
Experimental Physiology, EarlyView.Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

The Martian surface radiation environment – a comparison of models and MSL/RAD measurements
Journal of Space Weather and Space Climate, 2016 Context: The Radiation Assessment Detector (RAD) on the Mars Science Laboratory (MSL) has been measuring the radiation environment on the surface of Mars since August 6th 2012. MSL-RAD is the first instrument to provide detailed information about charged

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract Recent observations from the ExoMars Trace Gas Orbiter (TGO) have revealed the presence of hydrogen chloride (HCl) in the martian atmosphere. HCl shows strong seasonality, primarily appearing during Mars' perihelion period before decreasing faster than projected from photolysis and gas‐phase chemistry.

Sustainable colonization of Mars using shape optimized structures and in situ concrete
Scientific Reports, 2023 The major obstacle to Martian colonization is the mission cost which requires significant reduction. From the structural engineering point of view, importing materials and structural elements from Earth or massive excavations on the surface of Mars ...

Propagation and Periodicity of Mars's Northern Annular Mode Modulates the Dust Cycle
Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract We document the propagation of annular modes—zonally symmetric patterns of variability—in Mars's atmosphere using a reanalysis dataset. Mars's Northern Annular Mode (MNAM) sees anomalies of zonal‐mean zonal wind emerge near the subtropics and migrate poleward with a period of ∼ ${\sim} $150 days, similarly to Earth's Southern Annular Mode. The

Strong depletion of $^{13}$C in CO induced by photolysis of CO$_{2}$ in the Martian atmosphere calculated by a photochemical model [PDF]
arXiv, 2023 The isotopic signature of atmospheric carbon offers a unique tracer for the history of the Martian atmosphere and the origin of organic matter on Mars. Photolysis of CO$_{2}$ is known to induce strong isotopic fractionation of carbon between CO$_{2}$ and CO.
