This ancient disk was found in a Mars Surveyor image this month. Its circular shape is very typical of the flying saucers seen for many centuries around the world.
On one end of the disk is raised area that looks like an engine compartment or possible damage. This disk is totally out of place in this environment of ridges and cliffs in this crater. It is an ancient abandoned craft, probably damaged beyond repair or it tech was made obsolete by new tech.
