Perseverance's Mastcam-Z instrument provides high-resolution stereo and multispectral images with a unique combination of spatial resolution, coverage, wavelength coverage along the rover's traverse in Jezero crater, Mars. Images reveal rocks consistent an igneous (including volcanic and/or volcaniclastic) impactite origin limited aqueous alteration, including polygonally fractured weathered coatings; massive boulder-forming bedrock consisting mafic silicates, ferric oxides, iron-bearing...
Abstract Comet 67P/Churyumov‐Gerasimenko displays a pronounced hemispherical dichotomy in surface morphology, where the southern hemisphere exhibits more erosional features than northern due to receiving much greater solar radiation. Consequently, it is generally assumed that particles are ejected from through sublimation and significant fraction eventually descends as airfall, covering terrains. To investigate this south‐to‐north material transfer during comet's perihelion passage, we used...
Abstract Comets are active geological worlds with primitive surfaces that have been shaped to varying degrees by sublimation‐driven sediment transport and mass wasting processes. Rosetta's rendezvous comet 67P/Churyumov‐Gerasimenko (67P) in 2014 provided data the necessary spatial temporal resolutions observe many evolutionary processes on micro‐gravity worlds. observations thus far revealed changes surface occurred within 67P's smooth terrains, vast sedimentary deposits blanket a...

Rosetta’s rendezvous comet 67P/Churyumov-Gerasimenko (67P) in 2014 provided data the necessary spatial and temporal resolutions observe how micro-gravity evolve. observations thus far revealed majority of changes surface occurred within 67P’s smooth terrains, vast sedimentary deposits blanket a significant fraction nucleus.
