individual particles may not, however the concern is of build up as well as the interference caused when said build up occurs. Recent experimentation with the <10 mm fraction of mature hi-Ti mare soil 79221 has shown that a small hand magnet will easily attract practically all the grains, even those that are plagioclase. Travel over 500m will allow quite a bit of particles to be attracted from the surface. This is why I brought up the factor of incorporating a repulsive field at the openings to ensure no particles would become stuck inside.

Thank you for the welcome. I have a variety of interests, but nothing I'm even close to being a master at. I enjoy learning and thinking about nearly all the sciences from physics and engineering to social sciences and astronomy. Oh and let's not forget Botany and horticulture :esmoking: . Hopefully I will make a quality contribution to the forums. MITH

Another quick thought. If moon dust shares a similar charge throughout (to be assumed or it'd be a big clump any time it was kicked up), then couldn't a principal of levitation be used ala hoverboard as opposed to any physical connection with the ground? A floating rover could be pretty cool (steering could be an issue).

Hey GAHD, have you taken into consideration the magnetism (and thereby attraction) of the dust particles (caused by ferromagnetism) as indicated in the primary thread? Theoretically the wheel in a non operating mode could possibly avoid attracting particles if all particles share a similar charge and the "baseline" of the wheel was the same, however once you induced the stepper function you would have numerous particles attempting to reach the opposing force, thus contaminating your wheel. Perhaps the use of a magnetic field as a barrier of some sort would suffice but it would have to be passive or once power cut in a failure or temporary shutdown the particles could still be attracted by any remaining charge. Just wondering.... MITH

Just a note on what Turtle said: If you were to use the NASA method of heat exchange, what are you doing with the heat? Since we're on the issue of power supply, would not a logical reasoning be to use a passive energy production system ala turbine or something similar that could go "inline" with the heat transfer system. Just a quick thought. BTW, has anybody started a thread to discuss the various methods for "soft landing". And we should make sure the links to the various threadshoots easy access. Outs. MITH More Thoughts added: Since we're on the issue of transmission of the signal, since we are intending to do multiple rovers, should we not put in place a semi-permanent relay station for some open standard so future missions can make use of it, as well as act as a central operations hub for the x mission.

Meh. Not much. Just sketching out a mod for your wheel design. It's really just a modified conceptualization which may be "easier", but more prone to failure (possibly). Just mulling ideas over. You?

Allo, Salut and Bienvenue from the MITH. I have to do this all I'm relly interested in is the Lunar X Prize thread and involvement therein. Peace out.
