Photometric Survey of the Irregular Satellites [PDF]

, 2003
We present BVRI colors of 13 Jovian and 8 Saturnian irregular satellites obtained with the 2.56m Nordic Optical Telescope on La Palma, the 6.5m Magellan Baade Telescope on La Campanas, and the 6m MMT on Mt. Hopkins.

Onboard Science Instrument Autonomy for the Detection of Microscopy Biosignatures on the Ocean Worlds Life Surveyor

The Planetary Science Journal
The quest to find extraterrestrial life is a critical scientific endeavor with civilization-level implications. Icy moons in our solar system are promising targets for exploration because their liquid oceans make them potential habitats ...

Detection of Negative Carbon and Oxygen Pickup Ions From Dust Orbiting Jupiter

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract We report on observations of negative carbon and oxygen pickup ions (PUIs) originating from dust orbiting Jupiter. The PUIs are observed at altitudes of a few thousand kilometers (∼4,800–10,200 km) above the 1‐bar level of Jupiter's atmosphere and up to ∼11,000–15,000 km from the equatorial plane, thus providing constraints on the location of ...

Deuterated Water Ice on the Satellites of Saturn

The Planetary Science Journal
The deuterium-to-hydrogen ratio in water ice in a planetary body carries important information on the history of water processing and delivery in the protostellar nebula.

JWST/NIRSpec Detection of Complex Structures in Saturn's Sub‐Auroral Ionosphere and Stratosphere

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Past observations of Saturn's sub‐auroral ionosphere have provided no detailed longitudinal information, and variations in underlying stratospheric emission from methane fluorescence have never been resolved spatially. Here, we present the first near‐infrared observations of Saturn using JWST's NIRSpec‐IFU, revealing the 2.8–5.2 micron ...

Constraints from deuterium on the formation of icy bodies in the Jovian system and beyond

, 2008
We consider the role of deuterium as a potential marker of location and ambient conditions during the formation of small bodies in our Solar system. We concentrate in particular on the formation of the regular icy satellites of Jupiter and the other ...

Cold and Hot Electron Populations Observed by Juno‐JADE in the Jovian Magnetodisc

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Despite their importance to a variety of plasma processes in Jupiter's magnetosphere, properties of the thermal and suprathermal electrons have been sparsely reported in past literature. To address this gap, we used data from Juno's Jovian Auroral Distributions Experiment Electron sensors to survey electron properties in Jupiter's magnetodisc ...

Coupling between corotation and Lindblad resonances in the elliptic planar three-body problem

, 2013
We investigate the dynamics of two satellites with masses $\mu_s$ and $\mu'_s$ orbiting a massive central planet in a common plane, near a first order mean motion resonance $m$+1:$m$ ($m$ integer).

Origin of chaos in the Prometheus–Pandora system [PDF]

, 2003
We demonstrate that the chaotic orbits of Prometheus and Pandora are due to interactions associated with the 121:118 mean motion resonance. Differential precession splits this resonance into a quartet of components equally spaced in frequency.

A Comprehensive Framework for Assessing Terrestrial Analogue Field Sites for Ocean Worlds

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Field studies at terrestrial analogue sites represent an important contribution to the science of ocean worlds. The value of the science and technology investigations conducted at field analogue sites depends on the relevance of the analogue environment to the target ocean world.
