Temporal analysis of all high-resolution Mars imaging products [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 A meta-data analysis has been performed of high-resolution imagery that have been acquired over the last four decades from Mars. More specifically, we are interested in two independent image parameters, the time that each image was acquired and the ...

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

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Locally generated fast magnetosonic (local MS) waves in the Martian ionosphere have been reported recently, which are different from the solar wind‐driven MS waves. However, their effects on particle scattering have not been reported yet. This study pioneers the investigation of electron, proton, and oxygen atomic ion scattering induced by ...

New approaches to the exploration: planet Mars and bacterial life
, 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]
, 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.

The Promise of Solid Lubricants for a Sustainable Future
Advanced Materials, Volume 38, Issue 8, 6 February 2026.Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?
