Was using a old NASA index so old that even I have never heard of it. Been exploring different parts of it, learning about things I go. Posting a few things I thought you may be interested in. Here I found an alien city or base in the center of a huge crater. The map ruler says this structure is 15km across. Thats big enough to house 100,000+ people easy. I guess I should be surprised, but…I’ve been doing this for decades and after the first decade, very little surprises me anymore.
