Computer modeling of the mineralogy of the Martian surface, as modified by aqueous alteration [PDF]
Mineralogical constraints can be placed on the Martian surface by assuming chemical equilibria among the surface rocks, atmosphere and hypothesized percolating groundwater.

MarsQE: Semantic-Informed Quality Enhancement for Compressed Martian Image [PDF]
arXivLossy image compression is essential for Mars exploration missions, due to the limited bandwidth between Earth and Mars. However, the compression may introduce visual artifacts that complicate the geological analysis of the Martian surface. Existing quality enhancement approaches, primarily designed for Earth images, fall short for Martian images due ...

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract Recent observations from the ExoMars Trace Gas Orbiter (TGO) have revealed the presence of hydrogen chloride (HCl) in the martian atmosphere. HCl shows strong seasonality, primarily appearing during Mars' perihelion period before decreasing faster than projected from photolysis and gas‐phase chemistry.

Prototype Backscatter Moessbauer Spectrometer for Measurement of Martian Surface Mineralogy [PDF]
We have designed and successfully tested a prototype of a backscatter Moessbauer spectrometer (BaMS) targeted for use on the Martian surface to (1) determine oxidation states of iron, and (2) identify and determine relative abundances of iron-bearing ...

Propagation and Periodicity of Mars's Northern Annular Mode Modulates the Dust Cycle
Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.Abstract We document the propagation of annular modes—zonally symmetric patterns of variability—in Mars's atmosphere using a reanalysis dataset. Mars's Northern Annular Mode (MNAM) sees anomalies of zonal‐mean zonal wind emerge near the subtropics and migrate poleward with a period of ∼ ${\sim} $150 days, similarly to Earth's Southern Annular Mode. The

Demonstrating Martian Gravity [PDF]
arXiv, 2016 The surface gravity on Mars is smaller than the surface gravity on Earth, resulting in longer falling times. This effect can be simulated on Earth by taking advantage of air resistance and buoyancy, which cause low density objects to fall slowly enough to approximate objects falling on the surface of Mars.
