Date of discovery: Nov 22, 2017
Location of discovery: Mars, Sol 1898, Spirit Rover
I found this structure in a old Spirit Rover photo today. Its actually similar to others I have reported in the past in the fact that it seems to have a dark opening area on it. The entire object is only about two meters across, and on a hillside, yet its still horizontally balanced so that there is no sloping. So the structure is not tilted on the slope, but perfect for people living in and walking in it.
Remember the figures we have reported on Mars? Most are just a few cm tall. This is just another piece of that puzzle, which is almost complete.
