Description

Windblown dunes, ripples, and erosional features are seen on Earth, Venus, and Titan, while on Mars these features are ubiquitous and reflect the dominant agent of surface modification. Although the fundamental process is similar, the environments on these planetary objects are substantially different. Simulations conducted in the Planetary Aeolian Laboratory at NASA-Ames, coupled with field work and modeling, enable analyses of wind-related features and processes on planetary surfaces.
