The Atmosphere of Titan in Late Northern Summer from JWST and Keck Observations

Conor A. Nixon, Bruno Bézard, Thomas Cornet +42

Saturn's moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan's northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017)…

Water-Ice Dominated Spectra of Saturn's Rings and Small Moons from JWST

M. M. Hedman, M. S. Tiscareno, M. R. Showalter +11

JWST measured the infrared spectra of Saturn's rings and several of its small moons (Epimetheus, Pandora, Telesto and Pallene) as part of Guaranteed Time Observation program 1247.…

Infrared Characterisation of Jupiter's Equatorial Disturbance Cycle

Arrate Antuñano, Leigh N. Fletcher, Glenn S. Orton +6

We use an infrared dataset captured between 1984 and 2017 using several instruments and observatories to report five rare equatorial disturbances that completely altered the appear…

Atmospheric Science Questions for a Uranian Probe

Emma K. Dahl, Naomi Rowe-Gurney, Glenn S. Orton +5

The Ice Giants represent a unique and relatively poorly characterized class of planets that have been largely unexplored since the brief Voyager 2 flyby in the late 1980's. Uranus…

JWST molecular mapping and characterization of Enceladus' water plume feeding its torus

G. L. Villanueva, H. B. Hammel, S. N. Milam +18

Enceladus is a prime target in the search for life in our solar system, having an active plume likely connected to a large liquid water subsurface ocean. Using the sensitive NIRSpe…

Spitzer IRS Observations of Titan as a Precursor to JWST MIRI Observations

Brandon Park Coy, Conor A. Nixon, Naomi Rowe-Gurney +4

In this work we present, for the first time, infrared spectra of Titan from the Spitzer Space Telescope (). The data are from both the short wavelength-low resolution (S…

Sub-Seasonal Variation in Neptune's Mid-Infrared Emission

Michael T. Roman, Leigh N. Fletcher, Glenn S. Orton +10

We present an analysis of all currently available ground-based imaging of Neptune in the mid-infrared. Dating between 2003 and 2020, the images reveal changes in Neptune's mid-infr…

Refining Saturn's deuterium-hydrogen ratio via IRTF/TEXES spectroscopy

James S. D. Blake, Leigh N. Fletcher, Thomas K. Greathouse +7

The abundance of deuterium in giant planet atmospheres provides constraints on the reservoirs of ices incorporated into these worlds during their formation and evolution. Motivated…

Longitudinal Variations in the Stratosphere of Uranus from the Spitzer Infrared Spectrometer

Naomi Rowe-Gurney, Leigh N. Fletcher, Glenn S. Orton +5

NASA's Spitzer Infrared Spectrometer (IRS) acquired mid-infrared (5-37 microns) disc-averaged spectra of Uranus very near to its equinox in December 2007. A mean spectrum was const…

Spitzer's Solar System studies of asteroids, planets and the zodiacal cloud

David Trilling, Carey Lisse, Dale P. Cruikshank +13

In its 16 years of scientific measurements, the Spitzer Space Telescope performed a number of ground-breaking infrared measurements of Solar System objects. In this second of two p…

Ice Giant Atmospheric Science

Emma K. Dahl, Shawn Brueshaber, Richard Cosentino +24

This white paper, written in support of NASA's 2023-2032 Planetary Decadal Survey, outlines 10 major questions that focus on the origin, evolution, and current processes that shape…

Uranus in Northern Mid-Spring: Persistent Atmospheric Temperatures and Circulations Inferred from Thermal Imaging

Michael T. Roman, Leigh N. Fletcher, Glenn S. Orton +2

We present results from mid-infrared imaging of Uranus at wavelengths of 13.0 micron and 18.7 micron, sensing emission from the stratosphere and upper troposphere, acquired using t…
