Insulators need to be discharged after each wheel |
|
revolution. Sensor responses repeatable within one |
|
standard deviation in the noise of the signal. Insulators |
|
may not need to be cleaned after each revolution. Parent |
|
Technology- Mars Environmental Compatibility |
|
Assessment/Electrometer Electrostatic sensors with |
|
dissimilar cover insulators Protruding insulators |
|
tribocharge against regolith simulant Developed for use |
|
on the scoop for the 2001 Mars Odyssey lander Wheel |
|
Electrostatic Spectrometer Embedded electrostatic sensors |
|
in prototype Martian rover wheel If successful, this |
|
technology will enable constant electrostatic testing on |
|
Mars Air ionizing fan used to neutralize the surface |
|
charge on cover insulators . WES rolled on JSClA lunar |
|
simulant Control experiment -Static elimination not |
|
conducted between trials -Capacitor discharged after each |
|
experiment Charge neutralization experiment -Static |
|
elimination conducted between trials -Capacitor |
|
discharged after each experiment. Air ionizing fan used |
|
on insulators after each wheel revolution Capacitor |
|
discharged after each trial Care was taken to roll WES |
