Hugh Pickens writes writes: "Scientists have confirmed chemically a recent and rare invasion from Mars with 15 pounds of fresh Martian rocks falling in Morocco last July. A special committee of meteorite experts, which includes some NASA scientists, confirmed the test results Tuesday certifying that that the meteorites recently collected came from Mars. The biggest rock weighs more than 2 pounds. Astronomers think that millions of years ago something big smashed into Mars that sent fragments hurtling through the solar system. Occasionally, some fall on Earth."
