You just need the pizoelectric techniques I blogged about at Valencia some time ago. A very thin film, very low mass, very low power. Turn it on and the dust just goes away - it's amazing.

Oh, yeah; that'd work great!!! Do that biweekly or so, never a prob.

QUOTE (tasp @ Feb 29 2008, 05:00 PM)  * Any convenient nearby large appropriately spaced boulders we can park between for an enhanced venturi effect to keep the prevailing winds at a higher speed to reduce dust rate accumulation ? I believe that venturi effect was involved on the very first cleaning event that caught everybody by surprise. At this time, Spirit was sitting on the "north col" of Husband hill. Nevertheless as centworth point out, we'll not move for a while and if we rove again after winter, I guess that "north col" of Von Braun would be the right place to get some Venturi effect...unless you can point out the 2 right boulders !!! -------------------- |

Maybe there was some local enhancement to those winds, but functionally I think being anywhere within the center of Gusev would have been enough. See Spirit's cleaning event: The view from space |

QUOTE (slinted @ Feb 29 2008, 07:10 PM) I don't have a professional interest in unmanned space flight. That may be why, although I remember viewing the beginning of that linked page almost a year ago, I never read any further than the first paragraph. I totally missed the point of the article! I thought it was about the fact that Mar's had lots of seasonal dust devil tracks, and I already knew that.  I am glad that I got a chance to re-read the full article. If the last two sentences are still accurate, I may not be the only person to skip over the article.  ... there hasn't been a publication (or at least a conference abstract) on this event. Maybe it's not that surprising to the professionals? Jack |
