The enigmatic abundance of atomic hydrogen in Saturn's upper atmosphere
Lotfi Ben-Jaffel, Julie Moses, Robert A. West +5
A planet's Lyman-α (Lyα) emission is sensitive to its thermospheric structure. Here, we report joint Hubble Space Telescope (HST) and Cassini cross-calibration observations of the…
Spectropolarimetry as a Means to Address Cloud Composition and Habitability for a Cloudy Exoplanetary Atmosphere in the Habitable Zone
Robert A. West, Philip Dumont, Renyu Hu +3
In our solar system, the densely cloud-covered atmosphere of Venus stands out as an example of how polarimetry can be used to gain information on cloud composition and particle mea…
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…
Haze seasonal variations of Titan's upper atmosphere during the Cassini Mission
Benoît Seignovert, Pascal Rannou, Robert A. West +1
This study presents a 13 years survey of haze UV extinction profiles, monitoring the temporal evolution of the detached haze layer (DHL) in Titan's upper atmosphere (350-600 km). A…
Saturn's Seasonal Atmosphere at Northern Summer Solstice
L. N. Fletcher, L. Sromovsky, V. Hue +4
The incredible longevity of Cassini's orbital mission at Saturn has provided the most comprehensive exploration of a seasonal giant planet to date. This review explores Saturn's ch…
On the Use of Planetary Science Data for Studying Extrasolar Planets
Daniel J. Crichton, J. Steve Hughes, Gael Roudier +5
There is an opportunity to advance both solar system and extrasolar planetary studies that does not require the construction of new telescopes or new missions but better use and ac…
The seasonal cycle of Titan's detached haze
Robert A. West, Benoît Seignovert, Pascal Rannou +5
Titan's 'detached' haze, seen in Voyager images in 1980 and 1981 and monitored by the Cassini Imaging Science Subsystem (ISS), during the period 2004-2017, provides a measure of se…
Solar system science with the Wide-Field InfraRed Survey Telescope (WFIRST)
B. J. Holler, S. N. Milam, J. M. Bauer +30
We present a community-led assessment of the solar system investigations achievable with NASA's next-generation space telescope, the Wide Field InfraRed Survey Telescope (WFIRST).…
Aerosols optical properties in Titan's Detached Haze Layer before the equinox
Benoît Seignovert, Pascal Rannou, Panayotis Lavvas +2
UV observations with Cassini ISS Narrow Angle Camera of Titan's detached haze is an excellent tool to probe its aerosols content without being affected by the gas or the multiple s…
Saturn's Polar Atmosphere
Kunio M. Sayanagi, Kevin H. Baines, Ulyana A. Dyudina +3
This book chapter, Saturn's Polar Atmosphere, is to be published by Cambridge University Press as part of a multi-volume work edited by Kevin Baines, Michael Flasar, Norbert Krupp,…
Dynamics of Saturn's great storm of 2010-2011 from Cassini ISS and RPWS
Kunio M. Sayanagi, Ulyana A. Dyudina, Shawn P. Ewald +6
Saturn's quasi-periodic planet-encircling storms are the largest convecting outbursts in the Solar System. The last eruption was in 1990. A new eruption started in December 2010 an…
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…
Saturn's Seasonally Changing Atmosphere: Thermal Structure, Composition and Aerosols
Leigh N. Fletcher, Thomas K. Greathouse, Julianne I. Moses +2
The longevity of Cassini's exploration of Saturn's atmosphere (a third of a Saturnian year) means that we have been able to track the seasonal evolution of atmospheric temperatures…
