Hypotheses for Triton's Plumes: New Analyses and Future Remote Sensing Tests
Jason D. Hofgartner, Samuel P. D. Birch, Julie Castillo +14
At least two active plumes were observed on Neptune's moon Triton during the Voyager 2 flyby in 1989. Models for Triton's plumes have previously been grouped into five hypotheses,…
Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
The science case for spacecraft exploration of the Uranian satellites: Candidate ocean worlds in an ice giant system
Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +15
The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus' five largest '…
Titan: Earth-like on the Outside, Ocean World on the Inside
Shannon M. MacKenzie, Samuel P. D. Birch, Sarah Horst +30
Thanks to the Cassini-Huygens mission, Titan, the pale orange dot of Pioneer and Voyager encounters has been revealed to be a dynamic, hydrologically-shaped, organic-rich ocean wor…
Modeling transmission windows in Titan's lower troposphere: Implications for infrared spectrometers aboard future aerial and surface missions
Paul Corlies, George D. McDonald, Alexander G. Hayes +10
From orbit, the visibility of Titan's surface is limited to a handful of narrow spectral windows in the near-infrared (near-IR), primarily from the absorption of methane gas. This…
Migrating Scarps as a Significant Driver for Cometary Surface Evolution
Samuel Birch, Alexander Hayes, Orkan Umurhan +10
Rosetta observations of 67P/Churyumov-Gerasimenko (67P) reveal that most changes occur in the fallback-generated smooth terrains, vast deposits of granular material blanketing the…
Geomorphologic Mapping of Titan's Polar Terrains: Constraining Surface Processes and Landscape Evolution
Samuel Birch, Alexander Hayes, William Dietrich +18
We present a geomorphologic map of Titan's polar terrains. The map was generated from a combination of Cassini Synthetic Aperture Radar (SAR) and Imaging Science Subsystem imaging…
Titan Science with the James Webb Space Telescope (JWST)
Conor A. Nixon, Richard K. Achterberg, Mate Adamkovics +12
The James Webb Space Telescope (JWST), scheduled for launch in 2018, is the successor to the Hubble Space Telescope (HST) but with a significantly larger aperture (6.5 m) and advan…
The fate of ethane in Titan's hydrocarbon lakes and seas
Olivier Mousis, Jonathan I. Lunine, Alexander G. Hayes +1
Ethane is expected to be the dominant photochemical product on Titan's surface and, in the absence of a process that sequesters it from exposed surface reservoirs, a major constitu…
Meridional variation in tropospheric methane on Titan observed with AO spectroscopy at Keck and VLT
Máté Ádámkovics, Jonathan L. Mitchell, Alexander G. Hayes +10
The spatial distribution of the tropospheric methane on Titan was measured using near-infrared spectroscopy. Ground-based observations at 1.5 (H-band) were performed duri…
Simulations of Titan's paleoclimate
Juan M. Lora, Jonathan I. Lunine, Joellen L. Russell +1
We investigate the effects of varying Saturn's orbit on the atmospheric circulation and surface methane distribution of Titan. Using a new general circulation model of Titan's atmo…
