Direct Formation of Structural Components Using a Martian Soil Simulant [PDF]

Scientific Reports, 2017
Martian habitats are ideally constructed using only locally available soils; extant attempts to process structural materials on Mars, however, generally require additives or calcination.

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

Geophysical 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 ...

Microbes from Brine Systems with Fluctuating Salinity Can Thrive under Simulated Martian Chemical Conditions

Life, 2021
The waters that were present on early Mars may have been habitable. Characterising environments analogous to these waters and investigating the viability of their microbes under simulated martian chemical conditions is key to developing hypotheses on ...

How can a cooperative‐based organization of indigenous fisheries foster the resilience to global changes? Lessons learned by coastal communities in eastern Québec

Environmental Policy and Governance, Volume 32, Issue 6, Page 546-559, December 2022., 2022
Abstract Halieutic resources and small‐scale fisheries are globally under stress due to global changes. This phenomenon has very strong impacts on the socioeconomic situation of vast coastal areas worldwide and of the communities living there, whose economies rely on the ocean.

Development of non‐destructive analytical strategies based on Raman spectroscopy and complementary techniques for Mars Sample Return tested on Northwest Africa 1950 Martian meteorite

Journal of Raman Spectroscopy, Volume 53, Issue 12, Page 2068-2085, December 2022., 2022
A non‐destructive analytical methodology, based on Raman microscopy (single point and imaging), micro‐energy dispersive X‐ray fluorescence (μED‐XRF) imaging analysis, and scanning electron microscopy coupled to energy dispersive spectroscopy (SEM‐EDS), is suggested for a first analytical characterization for the Martian samples that will be taken to ...

The Mastcam‐Z Radiometric Calibration Targets on NASA's Perseverance Rover: Derived Irradiance Time‐Series, Dust Deposition, and Performance Over the First 350 Sols on Mars

Earth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract The Mastcam‐Z radiometric calibration targets mounted on the NASA's Perseverance rover proved to be effective in the calibration of Mastcam‐Z images to reflectance (I/F) over the first 350 sols on Mars. Mastcam‐Z imaged the calibration targets regularly to perform reflectance calibration on multispectral image sets of targets on the Martian ...
