A Slash Across Layered Deposits At Mars’ North Pole
Here, a straight-line feature cuts across many layers, seemingly changing their brightness and presumably indicating a major change in the layer properties.

Atmospheric CO2 Ice in the Martian Polar Regions: Physical and Spectral Properties From Mars Climate Sounder Observations
CO2 ice clouds are important for polar energy balance and the carbon dioxide cycle on Mars. However, uncertainties remain regarding their physical and radiative properties, which control how polar CO2 […]

InSight Pressure Data Recalibration, and Its Application to the Study of Long-Term Pressure Changes on Mars
Observations of the South Polar Residual Cap suggest a possible erosion of the cap, leading to an increase of the global mass of the atmosphere.
