Curiosity Confirms Origins of Martian Meteorites 35
littlesparkvt writes "Earth's most eminent emissary to Mars has just proven that those rare Martian visitors that sometimes drop in on Earth — a.k.a. Martian meteorites — really are from the Red Planet. A key new measurement of Mars' atmosphere by NASA's Curiosity rover provides the most definitive evidence yet of the origins of Mars meteorites while at the same time providing a way to rule out Martian origins of other meteorites."

Curiosity is just confirming the results of the Viking entry science neutral atmospheric composition experiment (different from the mass spectrometer operated on the surface). It's very nice to have this nailed down, but I don't think it changes anything.

Oh no it has not the exact same composition. But certain elemental and isotopic ratios are characteristic enough. Look at this abstract for example http://www.sciencedirect.com/science/article/pii/0012821X84901833
