Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System
Reviews of Geophysics, Volume 64, Issue 4, December 2026.Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

V-type Asteroids as the Origin of Mesosiderites
The Planetary Science Journal, 2023 We present the results of a campaign of hypervelocity impact experiments on natural mesosiderite targets, using representative main asteroid belt impact speeds. The objective is to document further the surface evolution of iron-rich asteroids.

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Active Asteroid 311P/PanSTARRS: Rotational Instability as the Origin of its Multitails?
The Astronomical Journal, 2023 The active asteroid 311P/PanSTARRS is one of the two targets of the planned Chinese asteroid exploration mission Tianwen-2. During 2013, 311P experienced several mass-loss events and exhibited multiple comet-like tails. Here we analyze the morphology and

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Water ice deposits occur on inner solar system bodies in sunlit and shadowed terrains. We develop approaches to remotely determine the mixing mode with regolith (areal vs. intimate), ice grain size, and abundance that reveal processes of ice formation, emplacement, and evolution.

Interrogating 16 Psyche’s Interior with Rotational Dynamics and Gravity Field
The Planetary Science Journal16 Psyche is an M-type main belt asteroid. 16 Psyche’s high density and radar-bright surface indicate a large iron content. However, the degree of Psyche’s internal differentiation is not known.

Ceres' Salty Ices: Sublimation‐Driven Evolution From Water Ice Exposures to Na‐Carbonate Deposits
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The dwarf planet Ceres hosts nine geologically recent water ice exposures revealed by NASA's Dawn mission. We investigated the 0.04–11 km2 sites using visible imagery and infrared (1.0–4.3 μm) reflectance spectroscopy. Ice occurrence was mapped, and its abundance, grain size, and mixing mode with local regolith were constrained with Hapke ...
