I see the coils in the sol 52 images but I think I also see them in the Sol 51 ones.
THe official images from earllier in the mission deemphasized the background "noise". I wonder if we may not have to wait for these or work out how to produce images like those to be certain that we are actually seeing Mar's former or current union members.
I suspect that they are using a system which subtracts the controls from the samples.
