This golf ball sized piece of iron-nickel meteorite was named “Egg Rock”. These types of meteorites are quite common on Earth. If you look closely, you may be able to see the shiny grid patterns that Curiosity’s #ChemCam instrument zapped into it with its laser for element confirmation. This photo was taken with Curiosity’s #MastCam on Sol 1535 (2016-11-30) and was color balanced to look as it would in daytime lighting on Earth. Instagram contrast enhanced photo.
