Journal ArticleDOI
Photopolarimetry from Voyager 2; Preliminary Results on Saturn, Titan, and the Rings
Arthur L. Lane,Charles W. Hord,Robert A. West,Larry W. Esposito,D. L. Coffeen,Makiko Sato,Karen E. Simmons,Richard B. Pomphrey,Richard B. Morris +8 more
TL;DR: The Voyager 2 photopolarimeter was reprogrammed prior to the August 1981 Saturn encounter to perform orthogonal-polarization, two-color measurements on Saturn, Titan, and the rings, and multiple, very narrow strands of material were found in the Encke division and within the brightest single strand of the F ring.
Journal ArticleDOI
Martian planetwide crater distributions - Implications for geologic history and surface processes
Laurence A. Soderblom,Laurence A. Soderblom,C.D. Condit,C.D. Condit,Robert A. West,Robert A. West,B.M. Herman,B.M. Herman,T.J. Kreidler,T.J. Kreidler +9 more
TL;DR: In this paper, three different diameter size ranges are considered in connection with the Martian crater distribution, taking into account small craters from 0.6 to 1.2 km, intermediate-sized cracers from 4 to 10 km, and large craters with diameters exceeding 20 km.
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 imaging of Titan's high‐latitude lakes, clouds, and south‐polar surface changes
Elizabeth P. Turtle,Jason Perry,Alfred S. McEwen,Anthony D. DelGenio,J. Barbara,Robert A. West,D. D. Dawson,Carolyn C. Porco +7 more
TL;DR: Early images of the south-polar region revealed numerous dark surface features and contemporaneous convective cloud systems, suggesting the presence of hydrocarbon lakes similar to those later detected at Titan's North Pole as mentioned in this paper.
Journal ArticleDOI
Evidence for aggregate particles in the atmospheres of Titan and Jupiter
Robert A. West,Peter H. Smith +1 more
TL;DR: In this paper, the optical properties of Titan's high-altitude haze are explained in terms of aggregate particles, whose mean projected area equals that of an 0.14-micron radius sphere.
