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…
The Case for Non-Cryogenic Comet Nucleus Sample Return
Keiko Nakamura-Messenger, Alexander G. Hayes, Scott Sandford +22
Comets hold answers to mysteries of the Solar System by recording presolar history, the initial states of planet formation and prebiotic organics and volatiles to the early Earth.…
The Science Case for Spacecraft Exploration of the Uranian Satellites
Richard J. Cartwright, Chloe B. Beddingfield, Tom Nordheim +14
The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moo…
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…
