There haven't been any rock images from Mars today, but I have collected a huge pile of rocks and dirt locally from digging the foundation for an array of 8x460W solar panels, south facing and swiveling for seasonal performance and ease of installation and maintenance.
Here is the rebar arrangement for the foundation and the threaded rod anchors that will hold the poles, still WIP, especially the details for the array structure.
Done in @freecad . Of course.
