We have composed before about how the USGS set jointly topo maps of some definitely out there areas, like, for occasion, Mars. Which whilst not fully simple, until you are a Mars rover, are really interesting and fun to glimpse at. Talking of, we downloaded the Mars map to see where Percy could possibly be and exactly where it could possibly trundle off to. We’re just in the process of acquainting ourselves with the map, so we just cannot pinpoint little Percy’s landing place just still, but if you would like to sign up for in the interplanetary orienteering, examine out the USGS link to their Mars maps, here.
