Characterization of dust activity on Mars from MY27 to MY32 by PFS-MEX observations [PDF]

, 2018
We present spatial and temporal distributions of dust on Mars from Ls = 331 in MY26 until Ls = 80 in MY33 retrieved from the measurements taken by the Planetary Fourier Spectrometer (PFS) aboard Mars Express.

Deriving IMF Properties From Mars Express Heavy Pickup Ion Measurements

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract We present Mars Express (MEX) observations of heavy pickup ions (HPUI) at Mars and a new method to derive interplanetary magnetic field (IMF) properties. The MEX HPUI measurements were organized using the upstream IMF directions measured by the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission.

Kinetic model of carbonate dissolution in Martian meteorite ALH84001 [PDF]

, 2003
The magnetites and sulfides located in the rims of carbonate globules in the Martian meteorite ALH84001 have been claimed as evidence of past life on Mars.

Field‐Aligned Proton Beams Upstream of the Martian Bow Shock: First Observations

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract We report fast sunward‐propagating energetic proton field‐aligned beams (FABs) observed about one Mars radius upstream of the Martian bow shock, recorded by the Solar Wind Ion Analyzer instrument on the MAVEN spacecraft. The velocity distributions show that all the beams have a bulk parallel speed vB=(1.35±0.21)VS ${v}_{B}=(1.35\pm 0.21){V}_{S}

A First Look at Carbon and Oxygen Stable Isotope Measurements of Martian Atmospheric C02 by the Phoenix Lander [PDF]

, 2009
Precise stable isotope measurements of the CO2 in the martian atmosphere have the potential to provide important constraints for our understanding of the history of volatiles, the carbon cycle, current atmospheric processes, and the degree of water/rock ...

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.
