Journal ArticleDOI
Liquid water on Enceladus from observations of ammonia and 40Ar in the plume
J. H. Waite,W. S. Lewis,Brian Magee,Jonathan I. Lunine,William B. McKinnon,Christopher R. Glein,Olivier Mousis,Olivier Mousis,D. T. Young,Tim Brockwell,Joseph Westlake,M. J. Nguyen,B. D. Teolis,Hasso B. Niemann,Ralph L. McNutt,Mark E. Perry,Wing-Huen Ip +16 more
TL;DR: McKinnon et al. as mentioned in this paper reported that ammonia is present in the plume, along with various organic compounds, deuterium and, very probably, Ar-40, which provides strong evidence for the existence of at least some liquid water, given that temperatures in excess of 180 K have been measured near the fractures from which the jets emanate.
Journal ArticleDOI
The composition and structure of the Enceladus plume
Candice Hansen,Donald E. Shemansky,Larry W. Esposito,A. I. F. Stewart,Brenton Lewis,Joshua Colwell,Amanda R. Hendrix,Robert A. West,J. H. Waite,B. D. Teolis,Brian Magee +10 more
TL;DR: In this paper, the authors observed an occultation of the Sun by the water vapor plume at the south polar region of Saturn's moon Enceladus and inferred the inferred rate of water vapor injection into Saturn's magnetosphere is ∼200 kg/s.
Journal ArticleDOI
Cassini finds an oxygen-carbon dioxide atmosphere at Saturn's icy moon Rhea
B. D. Teolis,Geraint H. Jones,P. F. Miles,R. L. Tokar,Brian Magee,J. H. Waite,Elias Roussos,D. T. Young,F. J. Crary,Andrew J. Coates,Robert E. Johnson,Wei-Ling Tseng,Raúl A. Baragiola +12 more
TL;DR: The flyby measurements of the Cassini spacecraft at Saturn’s moon Rhea reveal a tenuous oxygen (O2)–carbon dioxide (CO2) atmosphere that appears to be sustained by chemical decomposition of the surface water ice under irradiation from Saturn's magnetospheric plasma.
Journal ArticleDOI
Magnetospheric ion sputtering and water ice grain size at Europa
Timothy A. Cassidy,Chris Paranicas,James H. Shirley,J. B. Dalton,B. D. Teolis,Robert E. Johnson,L. W. Kamp,Amanda R. Hendrix +7 more
TL;DR: Pappalardo et al. as mentioned in this paper presented the first calculation of Europa's sputtering (ion erosion) rate as a function of position on Europa's surface and found a global sputtering rate of 2×10 27 ǫH 2 O s −1, some of which leaves the surface in the form of O 2 and H 2.
Journal ArticleDOI
Characterization of porosity in vapor-deposited amorphous solid water from methane adsorption.
TL;DR: In this paper, the porosity of vapor-deposited amorphous solid water (ice) films was characterized using several complementary techniques such as quartz crystal microgravimetry, UV-visible interferometry, and infrared reflectance spectrometry in tandem with methane adsorption.
