Hugh Pickens 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 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."
