How much higher would saltation curtain be on Mars than on Earth? Assume that the distribution of particle launch speeds and angles would be the same as on Earth; for simplicity, let us take the range of speeds from 0.1 m/s to 2 m/s, and all grains are launched at 45°. The acceleration of gravity on Mars is 3.75 m/s². Assume that the trajectories are ballistic – i.e. ignore drag in the vertical.
