Now it's very clear where Luna 17 landed. we have LRO images good enough to show the lander and rover and the wheel tracks. But what did we know before LRO? My first Moon atlas came out before LRO (so it was swiftly rendered out of date and some of my speculation was shown to be wrong). This illustration shows what I thought about the landing site in about 2005 when I was doing that work. Tracking and orbit data gave us a position accurate to within about 10 km. #maps #moon#Luna17 #lunokhod1
