The last works of Marzieh (Mari) Foroutan, an early-career martian geologist who was lost to us in 2020, have now been completed and published in JGR: Planets.
A new study of small impact craters at Mars landing sites suggests that active processes degrade and infill depressions at similar rates in locations separated by thousands of kilometers.
The second phase of Curiosity’s campaign at the Bagnold Dunes brought new observations of windblown sands during Mars’s windy season.
Europa’s churning ice crust could reveal signs of ocean life, new study suggests.
A new special issue of JGR: Planets presents findings on sand motion, morphology, and mineralogy from the Curiosity rover’s traverse of the active Bagnold dune field in Gale crater.
An analysis suggests that craters degrade faster on Mercury than the Moon, raising questions about landscape evolution on different planetary bodies.
New measurements of impact craters on Mercury’s smooth plains suggest that the topography of the solar system’s innermost planet is changing at twice the rate of landforms on the Moon.
The consistently shallow depths of the depressions scattered across Mercury's surface suggest their morphology is not determined by the thickness of a volatile-rich outer layer.
Manganese deposits in Gale Crater fractures are similar to Earth features that usually require flowing water and highly oxidizing conditions.
Temperature readings acquired from orbit show that Mars's surface gets cold enough at night to allow layers of solid carbon dioxide frost up to several hundred micrometers thick to build up near the equator.
