I read a Science news story on electric fields in dust storms on Earth LINK. A quick Google leads to NASA research on electric filed on dust devils on earth LINK. Does anyone here know if researches ever considered placing a small instrument to measure electric and magnetic fields on a rover? If Spirit and Opportunity had such instruments, we would have gotten great data during near fatal dust storm and also all the cleaning events they experienced. I would be surprised if a combined magnetic and electric field monitor with data logger could not be built weighing significantly less than an ounce.

Dust devils on earth create huge electric fields of up to 4,000 volts/meter and also contain magnetic fields. It would be good to ground truth this dust lifting phenomenon on Mars.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
