Identification (or otherwise) of martian carbon in martian meteorites [PDF]

open access: yes, 2008
One of the goals of current martian exploration is to search for evidence of extinct (or even extant) life. In recent years, this goal has been interpreted as a search for evidence of water on Mars’ surface. The success of instrumentation (high resolution cameras and infrared spectrometers) on orbiting spacecraft, coupled with in situ data from the MER

Plasma Acceleration by Magnetic Tension Forces in the Martian Magnetotail: MAVEN Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Martian magnetotail is a dynamic region where several processes contribute to plasma acceleration. Here, we analyze ∼5 ${\sim} 5$ years of Mars Atmosphere and Volatile EvolutioN (MAVEN) data to evaluate the role of magnetic tension forces in driving plasma acceleration within current sheets in the tail. Based on magnetic field measurements,

Volcanic features of Hawaii. A basis for comparison with Mars [PDF]

open access: yes
Despite the difference in size Martian and Hawaiian volcanoes have numerous characteristics in common. Specific features such as lava channels, collapsed lava tubes, levees and flow fronts, all very common in Hawaii, are also abundant on the flanks of ...

Formation of Caloris Basin's Positive Mass Anomaly by Thermal Contraction During Its Postimpact Evolution

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Caloris basin preserves a record of Mercury's volcanic and tectonic activity, including the long‐wavelength warping of its surface in the north‐south direction. As Mercury's largest mascon basin, identifying Caloris' configuration prior to volcanic infilling is a key step in determining the series of events that led to its current state. Here,

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Temporal and Spatial Prediction of Column Dust Optical Depth Trend on Mars Based on Deep Learning

open access: yesRemote Sensing
Dust storms, as an important extreme weather event on Mars, have significant impacts on the Martian atmosphere and climate and the activities of Martian probes. Therefore, it is necessary to analyze and predict the activity trends of Martian dust storms.
