Wave Heating of Magnetotail Current Sheet Electrons at Mars
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract The Martian magnetotail current sheet serves as a critical pathway for ionospheric ion escape. Contrary to the conventional view that external magnetic pressure is balanced mainly by internal ion thermal pressure, we present novel observations from the Mars Atmosphere and Volatile Evolution spacecraft of an electron‐dominated pressure balance ...

Photovoltaic array for Martian surface power [PDF]
Missions to Mars will require electric power. A leading candidate for providing power is solar power produced by photovoltaic arrays. To design such a power system, detailed information on solar-radiation availability on the Martian surface is necessary.

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract As one of the iconic features on Mars, global dust storms (GDSs) often decay rapidly. However, general circulation models (GCMs) typically underestimate their decay rates, which is one of the major challenges in simulating the Martian atmosphere. Here, we evaluate the role of a recently implemented size‐resolved microphysical deposition scheme

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Mars lacks an intrinsic global magnetic field but possesses crustal magnetic anomalies and an atmosphere. Mars' ionosphere, resulted from interactions between Mars' atmosphere and solar radiation, directly interacts with solar wind and interplanetary magnetic field (IMF). However, the mechanisms governing ion acceleration and escape from Mars'

High Frequency Radar Perspective of Putative Subglacial Liquid Water on Mars
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Anomalously bright radar reflections from the base of Mars' south polar cap raise the tantalizing possibility of present‐day liquid water. Orosei et al. (2018, https://doi.org/10.1126/science.aar7268) first reported bright subsurface echoes from the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) prompting studies of ...

Exploring Magnetic Reconnection in the Collisional Ionosphere of Mars With MAVEN
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract Magnetic reconnection in collisional plasmas has been widely studied in solar and laboratory plasma disciplines, but in situ measurements in space plasmas have rarely been utilized to explore this reconnection regime. Here we study collisional effects on magnetic reconnection in the Martian ionosphere by analyzing in situ data obtained by the ...

When Barchan Dunes Move Over Craters
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract We investigate the possible outcomes of a subaqueous barchan moving over a crater‐like depression in the bed. For that, we carried out experiments where we varied the dune size, crater and grain diameters, and flow velocities. We found that subaqueous barchans can be blocked, destroyed, or pass over craters, with transitional situations, and ...
