The objective of this complex-looking landscape is rather simple: looking for changes in long-monitored sites on the South Polar residual cap. Any detectable changes will be small. On Mars, a “residual cap” is the portion of each Martian polar cap that remains frosted through the summer. These depressions are likely the result of sublimating carbon-dioxide subsurface ice.
