The Curiosity Mars rover has found yet another strange looking object on the red planet. This time, a small shiny protuberance that was spotted by an enthusiast who sent it to Universe Today:
The image was taken with the right Mastcam on Curiosity on Sol 173 — January 30, 2013 here on Earth — (see the original raw image here), and was pointed out to us by Elisabetta Bonora, an image editing enthusiast from Italy. [...]
As Bonora pointed out, the protuberance seems different than the rock on which it sits – it could be composed of material more resistant to erosion than the rest and similar material could be within the rock, or it could be something that is “grown” on the rock.
However, it looks fairly smooth, and in fact it is not covered by dust as is the case for metal surfaces that tend to clean easily.
But “small” is the operative word here, as the little protuberance is probably about 0.5 cm tall, or even smaller.
