Peering Through Titan’s Haze to Better Understand Its Surface
Variations in grain size and water ice content detected on Saturn’s largest moon offer evidence of geologically related units that resemble the mountain-to-desert transition on Earth.

How Did Venus Get its Youthful Surface?
Catastrophic lithospheric recycling is unlikely to be the cause of Venus’s young surface from mantle convection models constrained by offset between the center of mass and center of shape of planet.

A Consistent Model of Ice Dissociation on Celestial Bodies
A model based on decades of experimental results can now quantify the products of water ice dissociation caused by radiation and predict the products expelled into an icy body’s outer atmosphere.

Evidence of Extensive Ice Deposits Near Mercury’s South Pole
New radar observations and refined illumination maps reveal uneven water ice deposits twice the size of those found around the planet’s north pole, suggesting the source may be a recent comet impact.

Elevated Heat Flow at Coronae on Venus
Enigmatic surface features on Venus called coronae are important for how Venus loses heat, and measurement of surface flexing around these features indicates higher heat flows than on Earth.
