    A team that includes researchers supported by the NASA Astrobiology Program has identified a new class of martian meteorite that likely originated from Mars’ crust. The meteorite, dubbed (Northwest Africa) NWA 7034, has also been dated to the Amazonian epoch on Mars, 2.1 billion years ago, Mars’ most recent geological epoch. NWA 7034 shows some unique geochemistry, including a high water content that might indicate interaction with surface water on Mars – either from volcanic magma or fluids from impacting comets. The study was published in a recent edition of Science Express.
