Mars Suit Outer Garment Fabric?
If there is such a high concentration of iron oxide in AMrs dust, perhaps it
can be repelled with a static charge? or active magnetic repulsion? Imagine, flick a switch, the dust "explodes" off the suit and settles out, instant clean...;-) |

Imagine, flick a switch, the dust "explodes" off the suit and settles out, instant clean...;-) Actually DART(Dust Accumulation and Removal Test)would study amoung other things the repulsive cleaning of solar cells... The Martian atmospheric dust is expected to be charged. The electrostatic experiment will use a high-voltage solar cell to provide a potential of about 80 V to a transparent conductor on the front surface of the solar cell cover-glass. It will test three configurationsa positive potential applied to the cell cover, a negative potential applied to the cell, and a transverse field applied across the cellto determine whether electrostatic fields can be used to mitigate the deposition of dust on solar arrays. These configurations will be compared with the control cell with no applied potential. DART's sensors will provide both scientific information and important engineering data on the operation of solar power systems on Mars. DART will measure the dust accumulation rate and the transmitted spectrum of the dust, and it will image individual settled particles to determine the size distribution and the particle shape, as well as gather information on electrostatic properties. DART was developed to fly as part of the MIP experiment on the (now postponed) Mars-2001 Surveyor Lander. The flight hardware was designed, built, and qualified for flight at the NASA Glenn Research Center, and it is ready to go to Mars. http://www.grc.nasa.gov/WWW/RT2000/5000/5410landis.html |
