Analogy with motion of blown sand

 

 

 

We have considered the collective movement of motes towards a target located in a portion of the Martian surface that extends over a range of several kilometers. This problem is part of a study for the design and fabrication of smart dust for future space exploration missions. A smart dust mote has approximately the density and volume of a coarse grain of sand. It follows that the uncontrolled motion of smart dust is determined by the same Aeolian processes of saltation, settling and surface creep that govern the movement of sand in desert regions (R.A. Bagnold, The physics of wind blown sand and desert dunes, Chapman and Hall, (1954).).
