Martian Rocks Land In Morocco 95
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."

No no no!
It's a perfectly valid question. What's so unique about the chemical composition of a rock from Mars that one could categorically say that it came from that planet and no other source?
Mars is an aggregate of rocks from the early solar system, so why wouldn't some of those rocks still be freely drifting around in our solar system? Also, Mars was practically smashed in half in it's early years, why wouldn't it be some of that rubble still floating around?
I've heard it numerous times now that meteorite is "definitely from Mars". One of these times I'd like to hear why they are so sure.
