WASHINGTON: A rock analysed by NASA's Mars rover Curiosity has a surprising and more varied composition that resembles rare rocks from the bowels of our planet, the US space agency said Thursday.
"This rock is a close match in chemical composition to an unusual but well-known type of igneous rock found in many volcanic provinces on Earth," Curiosity co-investigator Edward Stolper of the California Institute of Technology in Pasadena said in a statement.
