Dusty convection, convective activity powered by radiative heating of dust, is a ubiquitous phenomenon in Mars's atmosphere but is especially deep (that is, impactful on the middle atmosphere) and widespread during planet-encircling dust ev...
The microstructural evolution of water ice in the solar system through sintering [0.03%]
太阳系中水冰的微结构通过烧结作用的演化过程

J L Molaro et al.
Ice sintering is a form of metamorphism that drives the microstructural evolution of an aggregate of grains through surface and volume diffusion. This leads to an increase in the grain-to-grain contact area ("neck") and density of the aggre...
Oxidative alteration of ferrous smectites and implications for the redox evolution of early Mars [0.03%]
蒙脱石的氧化改性及对早期火星还原氧化演变的启示
Steven M Chemtob,Ryan D Nickerson,Richard V Morris et al.
Steven M Chemtob et al.
Surface conditions on early Mars were likely anoxic, similar to early Earth, but the timing of the evolution to oxic conditions characteristic of contemporary Mars is unresolved. Ferrous trioctahedral smectites are the thermodynamically pre...
A Survey of Small-Scale Waves and Wave-Like Phenomena in Jupiter's Atmosphere Detected by JunoCam [0.03%]
朱诺号相机在木星大气中检测到的小规模波浪和波动现象综述

Glenn S Orton et al.
In the first 20 orbits of the Juno spacecraft around Jupiter, we have identified a variety of wave-like features in images made by its public-outreach camera, JunoCam. Because of Juno's unprecedented and repeated proximity to Jupiter's clou...
Observations, Meteorites, and Models: A Preflight Assessment of the Composition and Formation of (16) Psyche [0.03%]
观察、陨石和模型：(16)Psyche的组成和形成机制的轨道任务前评估

L T Elkins-Tanton et al.
Some years ago, the consensus was that asteroid (16) Psyche was almost entirely metal. New data on density, radar properties, and spectral signatures indicate that the asteroid is something perhaps even more enigmatic: a mixed metal and sil...
Particle Ejection Contributions to the Rotational Acceleration and Orbit Evolution of Asteroid (101955) Bennu [0.03%]
颗粒喷射对小行星(101955)本努自转加速和轨道演化的影响

D J Scheeres et al.
This paper explores the implications of the observed Bennu particle ejection events for that asteroid's spin rate and orbit evolution, which could complicate interpretation of the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) and Yarkovsky e...
Impact Melt Facies in the Moon's Crisium Basin: Identifying, Characterizing, and Future Radiogenic Dating [0.03%]

Both Earth and the Moon share a common history regarding the epoch of large basin formation, though only the lunar geologic record preserves any appreciable record of this Late Heavy Bombardment. The emergence of Earth's first life is appro...

We create a vertically coarse, but complete, vertical profile of dust mixing ratio from the surface to the upper atmosphere over Gale Crater, Mars, using the frequent joint atmospheric observations of the orbiting Mars Climate Sounder (MCS)...

Landslides are among the most widespread geologic features on Ceres. Using data from Dawn's Framing Camera, landslides were previously classified based upon geomorphologic characteristics into one of three archetypal categories, Type 1(T1),...
The top-down solidification of iron asteroids driving dynamo evolution [0.03%]
铁质行星esimal的自上而下固化对发电机演化的影响

Jerome A Neufeld
The cores of some small planetesimals, such as asteroid (16) Psyche, are thought to have been exposed through collisions during the early solar system that removed their mantles. These small bodies likely solidified from the top down repres...
