Given the weight budget I feel that any needs analysis would classify a plow as a 'nice to have' and reject it in favour of more productive instrumentation. The broken wheel certainly churned up the regolith, but the first evidence of salt deposits came from Paso Robles when all wheels were operating. Given Opportunities experiences with soft soils is there any reason to suspect that Tyrone would have not been exposed regardless of the broken wheel since all wheels churned the salt up? Same with Gertrude Weise. Sure the dragging wheel made the salt very evident but is a plow really a good tradeoff - what would you take off to compensate?

Weight is critical in the cost benefit analysis. Does anyone have figures for the weight of the RAT and other instruments? If plow weighed 10 kg, no way. 1 kg, maybe. 0.1 kg, sure, but probably very difficult build it this light. What is the minimum weight of a motor/joint, fiberglass pole, and a very simple rake/plow/bit of curved plastic? Isn't its possible to construct a simple system at under 0.3 kg?

Perhaps we could just employ the Swiss version of the Rover.
OK. I have too much time on my hands at the moment.  Astro0 |

CE And the option I want is a full pit crew of little green Martians, to not only clean the panels but change the wheels, fix bad motor windings, replace the RAT, recharge the battery, and lift the rovers over the dunes when they get stuck. Unfortunately, due to the global Martian General Strike, this isn't currently possible.

What we need is to change the labor laws to make Mars a right-to-work state!
