Post Skiing on other planets - what problems?   Posted on: Mon Jan 30, 2006 11:46 am
The article "Skiing That Soft Lunar Powder" ( www.space.com/businesstechnology/060127 ... n_ski.html ) is reporting that a recent NASA article includes tips from Apollo astronuats to ski on the moon because of the prperties of its dust.

There is a problem with it because the dust grains are sharp edged.

But what about the electrostical charge of the dust -couldn't that be a problem because the ski would be charged too and attract it to the ski? Or would the charge of the ski simlyfy the skiing because its charge is equal to the charge of the grains and so repulses the grains?

???
