Gypsum’s crystalline facies and sample handling. Images of the studied twinned selenite crystal and of the sample preparation and handling for optical microscopy, SEM-EDX, and LIMS analyses. (A) Smal crystal selenite (SC) and decimeter-sized twinned arrow-head selenite (TS) crystals show the darker re-entrant angle of the crystals (dashed black lines). (B) Large petrographic thin section of the re-entrant angle of the twinned selenite crystal marked in the blue rectangle in (A). It shows very turbid (vTL), turbid (TL) and limpid laminations (LL). (C) Small petrographic thin section of turbid laminae fixed on the LIMS sample holder with copper tape. (D) Gold coated sample on the LIMS sample holder.

Mars Welcomes Spring with Avalanches, Ice Explosions and Swirling Dunes

This image taken by NASA’s Mars Reconnaissance Orbiter shows ice sheets at Mars’ south pole.

Mars Ice Deposits May Harbor Potential for Microbial Life

Gravity map of Mars. The red circles show prominent volcanoes on Mars and the black circles show impact crates with a diameter larger than a few 100 km. A gravity high signal is located in the volcanic Tharsis Region (the red area in the centre right of the image), which is surrounded by a ring of negative gravity anomaly (shown in blue).

Gravity study gives insights into hidden features beneath lost ocean of Mars and rising Olympus Mons

$Here's a clearer version: An illustration shows the Martian interior beneath NASA's Insight lander. The top 5 kilometers of the crust seem to be dry, but a new study suggests there's a zone of fractured rock 11.5-20 kilometers below the surface that contains a significant amount of liquid water—more than what was thought to have filled ancient Martian oceans.
