Rapid Response of Martian Magnetotail to Solar Wind Disturbance: Tianwen‐1 and MAVEN Joint Observations

open access: yesGeophysical Research Letters
The Martian magnetotail is largely controlled by the solar wind (SW) and is modulated by variations in the upstream drivers. However, due to the limitations of single‐spacecraft observations, the effects of SW variations on the Martian magnetotail have ...

Chalcophile Element Constraints on the Sulfur Content of the Martian Mantle [PDF]

open access: yes
The sulfur content of the Martian mantle is critical to understanding volcanic volatiles supplied to the surface of Mars and possibly climate. In the absence of Martian mantle rocks, sulfur content of the mantle has been inferred from S contents of ...

On the Impact Origin of Phobos and Deimos I: Thermodynamic and Physical Aspects

open access: yes, 2017
Phobos and Deimos are the two small moons of Mars. Recent works have shown that they can accrete within an impact-generated disk. However, the detailed structure and initial thermodynamic properties of the disk are poorly understood.

Olivine–gabbroic shergottites: A petrogenetic link between poikilitic and gabbroic shergottites

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Shergottites span a textural, mineralogical, and geochemical range, and finding links between the various petrologic and geochemical groups is of great interest as it provides insight into the conditions of the Martian interior. Here, we compare the texture, mineralogy, mineral chemistry, and geochemistry of REE‐enriched intrusive shergottite ...

Thinking food delivery platforms infrastructurally: The practices and politics of Baemin's infrastructuralisation in Seoul

open access: yesNew Technology, Work and Employment, EarlyView.
Abstract The proliferation of food delivery platforms is profoundly changing the way urbanites eat, work, and move. These platforms increasingly mobilise urban resources and population to function as critical infrastructure in the field of logistics and transportation, giving rise to a new form of governance.

Distinguishing Underlying, Inferred, and Expressed Preferences, Attitudes, and Beliefs: An Absence of (Mental) Flatness?

open access: yesTopics 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.

Annual variations in the Martian bow shock location as observed by the Mars Express mission

open access: yes, 2016
The Martian bow shock distance has previously been shown to be anticorrelated with solar wind dynamic pressure but correlated with solar extreme ultraviolet (EUV) irradiance.

New approaches to the exploration: planet Mars and bacterial life

open access: yes, 2011
Planet Mars past environmental conditions were similar to the early Earth, but nowadays they are similar to those of a very cold desert, irradiated by intense solar UV light. However, some terrestrial lifeform showed the capability to adapt to very harsh

The depth of the convective boundary layer and implications for a Walker-like circulation on Mars [PDF]

open access: yes, 2011
Radio science observations indicate that the depth of the martian convective boundary layer varies strongly with surface height, although the surface temperature does not.
