Modeling the Formation of Selk Impact Crater on Titan: Implications for Dragonfly
The Planetary Science Journal, 2023 Selk crater is an ∼80 km diameter impact crater on the Saturnian icy satellite Titan. Melt pools associated with impact craters like Selk provide environments where liquid water and organics can mix and produce biomolecules like amino acids. It is partly

Energetic Constraints on Ocean Circulations of Icy Ocean Worlds
The Planetary Science Journal, 2023 Globally ice-covered oceans have been found on multiple moons in the solar system and may also have been a feature of Earth’s past. However, relatively little is understood about the dynamics of these ice-covered oceans, which affect not only the ...

Material Properties of Organic Liquids, Ices, and Hazes on Titan
The Astrophysical Journal Supplement Series, 2023 Titan has a diverse range of materials in its atmosphere and on its surface: the simple organics that reside in various phases (gas, liquid, and ice) and the solid complex refractory organics that form Titan’s haze layers.

Astrobiology eXploration at Enceladus (AXE): A New Frontiers Mission Concept Study
The Planetary Science Journal, 2023 The Saturnian moon Enceladus presents a unique opportunity to sample the contents of a subsurface liquid water ocean in situ via the continuous plume formed over its south polar terrain using a multi-flyby mission architecture.

Magnetospheric considerations for solar system ice state [PDF]
, 2018 The current lattice configuration of the water ice on the surfaces of the inner satellites of Jupiter and Saturn is likely shaped by many factors. But laboratory experiments have found that energetic proton irradiation can cause a transition in the ...

NEOWISE: Observations of the Irregular Satellites of Jupiter and Saturn [PDF]
, 2015 We present thermal model fits for 11 Jovian and 3 Saturnian irregular satellites based on measurements from the WISE/NEOWISE dataset. Our fits confirm spacecraft-measured diameters for the objects with in situ observations (Himalia and Phoebe) and ...

Photometry of Irregular Satellites of Uranus and Neptune [PDF]
, 2004 We present BVR photometric colors of six Uranian and two Neptunian irregular satellites, collected using the Magellan Observatory (Las Campanas, Chile) and the Keck Observatory, (Manua Kea, Hawaii).

Tethys’s Heat Fluxes Varied with Time in the Ithaca Chasma and Telemus Basin Region
The Planetary Science Journal, 2023 We investigated how lithospheric heat fluxes varied temporally and spatially on the Saturnian moon Tethys, focusing on the region of Ithaca Chasma that overprints Telemus Impact Basin.

Spitzer IRS Observations of Titan as a Precursor to JWST MIRI Observations
The Planetary Science Journal, 2023 In this work, we present for the first time infrared spectra of Titan from the Spitzer Space Telescope (2004–2009). The data are from both the short wavelength–low resolution (SL; 5.13–14.29 μ m, R ∼ 60–127) and short wavelength–high resolution (SH; 9.89–
