The asteroid (16) Psyche may be the metal-rich remnant of a differentiated planetesimal, or it
may be a highly reduced, metal-rich asteroidal material that never differentiated. The NASA …

The objective of the NASA Psyche mission gravity science investigation is to map the mass
distribution within asteroid (16) Psyche to elucidate interior structure and to resolve the …

In order to improve our understanding of the interior structure of Saturn's small moon
Enceladus, we reanalyze radiometric tracking and onboard imaging data acquired by the …

The atmospheric dynamics of Jupiter are dominated by strong zonal winds engulfing the
planet. Since the first gravity measurements taken by Juno at Jupiter, the low-degree gravity …

The tumultuous early era of outer solar system evolution culminated when Neptune migrated
across the primordial Kuiper Belt (PKB) and triggered a dynamical instability among the …

We report a design for gravity gradient measurements based on Sagnac interferometry. A
structure with two masses is designed to convert the effect of gravity gradients into rotational …

Ceres, the only dwarf planet in the inner Solar System, appears to be a relict ocean world.
Data collected by NASA's Dawn spacecraft provided evidence that global aqueous …

Impacts into icy bodies often generate near‐surface melt chambers and thermal
perturbations that soften the ice. We explore the post‐impact evolution of non‐penetrating …

Abstract Hera represents the European Space Agency's inaugural planetary defense space
mission and plays a pivotal role in the Asteroid Impact and Deflection Assessment …

Io experiences tidal deformation as a result of its eccentric orbit around Jupiter, which
provides a primary energy source for Io's continuing volcanic activity and infrared emission …
