Phys. Rev. Lett. 98, 198001 (2007) [4 pages]Saltation Transport on MarsReceived 2 October 2006; published 11 May 2007 We present the first calculation of saltation transport and dune formation on Mars and compare it to real dunes. We find that the rate at which grains are entrained into saltation on Mars is 1 order of magnitude higher than on Earth. With this fundamental novel ingredient, we reproduce the size and different shapes of Mars dunes, and give an estimate for the wind velocity on Mars. © 2007 The American Physical Society URL:
