A small coin found on Mars pictures. Take a look: It is a 3D anaglyph image, so it is best seen with 3D glasses.
no pennycase your not missing much because i've got some 3D glasses (there not the best in the world) and you dont see much
How are we sure it's a coin??? Why not a uhhh.... Plate perhaps, or a martian hubcap? My guess is that it is a breath mint
Breath mint on Mars? I did not know that Martians breath! They must eat or drink oxygenators, since there is so little of atmosphere out there
The image at the start of this thread looks more like verdigris on a copper coin with some gunk thrown in for good measure than anything else. Here's something truly `off planet'...an (inter)stellar example too!
