A photo of the Mars rover went viral as it shows something that looks like a thigh bone. See the photo below.
The Mars rover Curiosity sent us another snap from Mars that went viral. Using its MastCam, Curiosity made a photo of something that looks like a femur thigh bone. NASA says though that this is not a bone, but a rock that has been shaped by either water or wind in the shape of a bone.
See the photo in hi-res below.
Curiosity is still trying to find evidence that there has been life on Mars. So far no luck. Scientists expect to find small simple life forms like microbes. They do not think that larger life forms have ever lived on Mars as their is no atmosphere.
The Mars rover Curiosity has been on Mars for two years. He is still trucking around trying to find signs of life on Mars.
