Going To Mogollon..., ...and points South Options

[Bill Harris]

It was already said that those structures seen on previous hazcam pics (well, in all sort of cameras and filters...) were delicate.

But what about these ones? It looks like the smallest touch could broke them.

PS: It's time to open a new thread, don't you think so?

Good idea. That topic was "tired" and had the cord showing.

Delicate, to be sure. One thing I've noticed is that the "ledge-forming" rocks are a layer and extend to the right and left of where we camped out. I wonder if that feature is related to the bluff at Mogollon Rim?

We need to check out the "mobile dust" at that site and see if there has been more movement during the stopover.

Actually, the present strategy means the arm is never permanently stowed. It only gets stowed during a long drive, then immediately unstowed to the ready position at the end of the drive. This is to ensure that the arm is unstowed if/when the joint 1 motor finally gives out.

The joint 1 motor (with the broken winding) is difficult to operate because its electrical properties fluctuate as the motor goes through a turn, as the broken wire commutates. This only causes trouble when the motor is starting or stopping, as it has to overcome the magnetic detents.

One solution for keeping the unstowed the arm with minimal harm due to the surface vibration caused by the unlevel surface and/or passing over any stones is that Oppy must look another ways that is sand. The sand surface are very, very smooth, it is very very nice to drive over that and it is almost alike to surf among sea waves. That is try to travel close to the ripples of sand if the center have outcrops.
