Sometimes, when Google has one of those seasonal logos I click on it - to see what it’s about. Just now I noticed that the Google logo has a red planet with some little aliens representing the first “O” in Google. Out of curiosity I clicked on it, the image links to Google Mars, which is like Google Maps. Unfortunately it can’t be used with Google Earth client.

The blurb claims these are some of the most detailed maps of Mars ever made. I don’t know if the maps cover the whole planet, as admittedly my Martian geography is pretty poor.

Just for the fun of it I tried moon.google.com and it resolves. Go take a look and make sure to zoom in

The rest of the planets don’t resolve. You can aslo get to Google Mars via mars.google.com.
