Global pattern of Titan's dunes: Radar survey from the Cassini prime mission

  journal={Geophysical Research Letters},
We present a map of the orientation and extent of Titan's sand dunes derived from the complete radar imaging dataset from the Cassini prime mission. The 16,000 dune segments we have mapped cover ∼8% of the Titan's surface (suggesting a total coverage of ∼20%), are confined within 30° of the equator, and show local and regional deviations of dune orientation of up to about 40° from due Eastwards. There is no obvious global longitudinal pattern, although some divergence with latitude is apparent… 

Rapid and Extensive Surface Changes Near Titan’s Equator: Evidence of April Showers

The detection by Cassini's Imaging Science Subsystem of a large low-latitude cloud system early in Titan’s northern spring and extensive surface changes in the wake of this storm are reported, which suggests that the dry channels observed at Titan's low latitudes are carved by seasonal precipitation.

Growth mechanisms and dune orientation on Titan

Dune fields on Titan cover more than 17% of the moon's surface, constituting the largest known surface reservoir of organics. Their confinement to the equatorial belt, shape, and eastward direction

The Sand Seas of Titan: Cassini RADAR Observations of Longitudinal Dunes

The most recent Cassini RADAR images of Titan show widespread regions that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth, and the distribution and orientation of the dunes support a model of fluctuating surface winds.

Dune-forming winds on Titan and the influence of topography

Imaging of Titan from the Cassini spacecraft

Observations of Titan from the imaging science experiment onboard the Cassini spacecraft reveal intricate surface albedo features that suggest aeolian, tectonic and fluvial processes, and imply that substantial surface modification has occurred over Titan's history.

Titan's inventory of organic surface materials

Cassini RADAR observations now permit an initial assessment of the inventory of two classes, presumed to be organic, of Titan surface materials: polar lake liquids and equatorial dune sands. Several

Prediction of aeolian features on planets : application to Titan paleoclimatology

We examine the conditions necessary to form aeolian features on planets such as ripples and dunes. Specifically, we compute saltation and suspension speeds for the terrestrial planets, Triton, Titan,

Aeolian sediment transport pathways and aerodynamics at troughs on Mars

[1] Interaction between wind regimes and topography can give rise to complex suites of aeolian landforms. This paper considers aeolian sediment associated with troughs on Mars and identifies a wider


Titan is a unique place in the solar system. Not only is it a world with a dynamic atmosphere and a diverse landscape [1, 2, 3], but its low-gravity, thick-atmosphere environment lends itself to
