Three main colours

I walked 6.7km in the morning. During my walk, I noticed this landscape that seems to be divided in three main colours...

Work on the rover is progressing nicely. All parts have been printed. It didn’t look like that would be the case for a while, as printing the cover of the rover did not seem to work. The printer’s nozzle was clogged. I never had this happening so I had to search on the internet for a solution. Luckily I found one that worked and now all the parts have been printed. We’ve already done a bit of assembling; see the extra image for today. Now we have to wait for the electronic components to be delivered and that could take a couple of weeks...
