Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data

open access: yesGeodesy and Geodynamics, 2022
The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

A Mars Environment Chamber Coupled with Multiple In Situ Spectral Sensors for Mars Exploration

open access: yesSensors, 2021
Laboratory simulation is the only feasible way to achieve Martian environmental conditions on Earth, establishing a key link between the laboratory and Mars exploration. The mineral phases of some Martian surface materials (especially hydrated minerals),

Constructing citizenship and indigeneity in Jordan: The politics of Bedouin rights and identities in cultural heritage sites

open access: yesThe Geographical Journal, EarlyView.
Short Abstract This paper explores the relationships between Bedouin rights, citizenship and indigeneity in cultural heritage sites in Jordan. Through interviews and ethnographic fieldwork with Bedouin communities, we argue that a more critical engagement with indigeneity is necessary in Jordan.

Towards a global model of the martian atmosphere [PDF]

open access: yes, 2003
In an effort to continuously improve the capabilities of the Martian atmospheric predictions at LMD, the GCM has been extended into thermospheric heights thus creating the first model to self-consistently couple the lower and upper regions of the ...

A review of volatiles in the Martian interior [PDF]

open access: yes, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

Human Attention as a Philosophical Problem: The Question, and the Nature of Questions

open access: yesMetaphilosophy, EarlyView.
Abstract Human attention has become a touchstone of widespread concern across the humanities, sciences, and broader culture in much of the world. The emergence of a new, heavily capitalized, and technologically sophisticated industry “commodifying” human attention (what has been called “human fracking”) has given rise to a transdisciplinary ...

Martian Bow Shock Oscillations Driven by Solar Wind Variations: Simultaneous Observations From Tianwen‐1 and MAVEN

open access: yesGeophysical Research Letters, 2023
The Martian bow shock stands as the first defense against the solar wind and shapes the Martian magnetosphere. Previous studies showed the correlation between the Martian bow shock location and solar wind parameters.
