Ariel’s Medial Grooves: Spreading Centers on a Candidate Ocean World

The Planetary Science Journal
We present evidence that Ariel's massive chasma-medial groove systems formed via spreading, where internally sourced material ascended and formed new crust.

The Science Case for Spacecraft Exploration of the Uranian Satellites

, 2020
The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moons, as well as its ring moons and irregular satellites, remain poorly understood. We assert that a Flagship-class orbiter is needed to explore the Uranian satellites.

Elastic thickness and heat flux estimates for the uranian satellite Ariel [PDF]

Icarus, 2015
The surface of Ariel, an icy satellite orbiting Uranus, shows extensional tectonic features suggesting an episode of endogenic heating in the satellite's past. Using topography derived from stereo-photoclinometry, we identified flexural uplift at a rift zone suggesting elastic thickness values in the range 3.8-4.4 km. We estimate the temperature at the

Estimating Soft X‐Ray Emission From Uranus's Magnetosheath

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Soft X‐ray emission occurs within planetary magnetosheaths when highly charged solar wind ions undergo charge exchange with neutrals. The emission can provide dynamic views of the magnetosheath and cusps, allowing for investigations of the solar wind interaction with a planetary magnetosphere.

Ocean Worlds Maintained by Ocean Tidal Heat Expected on Several Uranian Moons

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract In recent NASA decadal surveys, detecting oceans among Uranus' moons has been identified as a research priority in future missions. Currently, the prevailing view in planetary science is that the likelihood of finding oceans is highest on the larger moons, Titania and Oberon, due to their higher integrals of radiogenic heat sources.

Internal Heat Flux and Energy Imbalance of Uranus

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract With its extreme axial tilt, Uranus' radiant energy budget (REB) and internal heat flux remain among the most intriguing mysteries in our solar system. By combining observations with modeling, we present the global REB over a complete orbital period (1946–2030), revealing significant seasonal variations.

The 3:1 mean motion resonance between Miranda and the inner Uranian satellites, Cressida and Desdemona

, 2014
We build a simple dissipative analytical model considering an averaged restricted 3-body problem taking into account the effect of the oblateness of a planet on a small satellite and on its perturber.

Cratering and Tectonic History of the Largest Uranian Satellite, Titania: New Insights Enabled by Image Reprocessing

The Planetary Science Journal
From heavily cratered Umbriel to extensively tectonized Miranda, Titania is an intermediary of the Uranian system: heavily cratered, yet tectonically modified. An outstanding mystery in Titania's crater population is its apparent relative lack of large (>

Variation of Model‐Predicted Reconnection Voltages Applied to Uranus' Dayside Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Uranus provides a key missing piece for fundamentally understanding solar wind‐magnetospheric interactions due to its location in the outer solar system. Whether the viscous‐like interaction overtakes global magnetic reconnection as the dominant process at the magnetopause of the outer planets remains unresolved.

Feasibility of Passive Sounding of Uranian Moons using Uranian Kilometric Radiation

, 2023
We present a feasibility study for passive sounding of Uranian icy moons using Uranian Kilometric Radio (UKR) emissions in the 100 - 900 kHz band. We provide a summary description of the observation geometry, the UKR characteristics, and estimate the ...
