Mars rover Curiosity photographed a strange unnatural looking object sitting or docking between rocks on top of a mountain.
Could it be a small alien craft or probe or eventually a building structure or is it just an optical illusion?
If you compare the black/white images (SOL 1046) with similar images from the same area (SOL 1047) then you can see the top of the mountain and the unknown object in the black/white images, but it appears that NASA has left out this part of the mountain in the much brighter and clearer color images.
Why? There is something to hide for the public?
