Mastcam-Z is a multispectral, stereoscopic imaging investigation on the Mars 2020 mission's
Perseverance rover. Mastcam-Z consists of a pair of focusable, 4: 1 zoomable cameras that …

This work constructs a fracture mechanics framework for conceptualizing mechanical rock
breakdown and consequent regolith production and erosion on the surface of Earth and …

Spacecraft observations revealed that rocks on carbonaceous asteroids, which constitute
the most numerous class by composition, can develop millimeter-to-meter-scale fractures …

Exfoliation of rock deteriorates cliffs through the formation and subsequent opening of
fractures, which in turn can lead to potentially hazardous rockfalls. Although a number of …

Rock breakdown due to diurnal thermal cycling has been hypothesized to drive boulder
degradation and regolith production on airless bodies. Numerous studies have invoked its …

Mineral‐filled fractures (veins) are valuable indicators of deformation and fluid flow within a
sedimentary package. Information obtained from vein morphology, texture, and chemistry …

Abstract Many boulders on (101955) Bennu, a near‐Earth rubble pile asteroid, show signs
of in situ disaggregation and exfoliation, indicating that thermal fatigue plays an important …

On asteroids, fractures develop due to stresses driven by diurnal temperature variations at
spatial scales ranging from sub-millimetres to metres. However, the timescales of such rock …

The underground coal gasification (UCG) mining technology constitutes an innovative form
of clean energy technology pertaining to coal resources. The sandstone specimens from the …

Abstract The Mars Science Laboratory (MSL) rover spent a full martian year exploring the
phyllosilicate‐bearing Glen Torridon trough on the flank of Aeolis Mons in Gale crater …
