Magnetic Flux Ropes at Mars and Their Impacts on Heavy Ion Escape
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Flux ropes (FRs), ubiquitous helical magnetic structures in solar system plasmas, are important to energy and particle transport. At Mars, where global intrinsic magnetic fields are absent, FRs form through magnetic reconnection (MR) and magnetospheric or ionospheric boundary wave instabilities (BWIs), but their role in ion escape remains ...

A hybrid origin for the Martian atmosphere
Geochemical Perspectives LettersThe Martian isotopic record displays a dichotomy in volatile compositions. Interior volatiles from the mantle record a chondritic heritage (e.g., H, N, Kr, Xe) whereas the atmospheric reservoir of Kr and Xe - which do not currently experience escape - record heritage from a solar-like source.

An estimation of the mass dragged by the solar wind from Mars’s atmosphere in its geologic history [PDF]
Geofísica Internacional, 2001 In the past Mars had a denser atmosphere, but it lacks a magnetic field to protect the ionosphere and exosphere from the solar wind. A model for describing the loss of atmosphere in geologic time is presented.

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.

Seven-year climatology of dust opacity on Mars [PDF]
, 2012 This paper describes the procedure we have used to produce multi-annual dust scenarios for Martian years 24 to 30 from a multi-instrument dataset of total dust opacity observations.

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract Martian linear dune gullies are landforms consisting of parallel and often sinuous channels with distinct levees and pit‐shaped endings that occur in the mid‐latitudes on Mars. Recent observations link their formation to sublimating CO2 ${\text{CO}}_{2}$‐ice blocks that slide downslope in early spring. Here we combine laboratory experiments in

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract We present high‐precision Ni stable isotope data for mesosiderites, eucrites, and diogenites to investigate the accretion and differentiation of asteroid 4 Vesta. Ni isotope variations in eucrites and diogenites are dominated by kinetic diffusion and chondritic contamination, rendering them unsuitable for reconstructing Vesta's primitive Ni ...

The chemical effects of the Martian environment on power system component materials: A theoretical approach [PDF]
In the foreseeable future, an expedition may be undertaken to explore the planet Mars. Some of the power source options being considered for such a mission are photovoltaics, regenerative fuel cells and nuclear reactors.
