The Daily Mail (U.K.) has a couple of photos taken by the NASA Mars rover Curiosity which show objects that appear not to be part of a never occupied planet. Hat tip to Drudge Report for the link.
One may be a piece of the rover's reentry material or it could be alien technology. The other photo sure looks like the end of a large animal bone, perhaps a femur or equivalent, protruding from the soil.
We need to get people to Mars to explore and colonize. It seeems tech moguls, not the geriatric government, will make it happen. Somewhere the ghost of Robert Heinlein nods knowingly.
