Martian dust appears on the surface of a penny in a photo by the Mars Hand Lens Imager aboard NASA's Curiosity rover on October 2. http://www.cnn.com/2012/08/14/tech/gallery/mars-curiosity-rover/index.html Apparently the news of the US Government shutdown hasn't reached the Red Planet.
Looks like a counterfeit now. BTW any one looking at Saturn at night? You can even see the rings. Jupiter, Venus and two exo planets are also showing.
It did, however, stop the broadcasts I like to watch from the ISS, and everything else on the NASA channel on my TV.
