Martian Rock Found In Morocco
daeley writes "The BBC is reporting that a rock found in 2001 in Morocco is originally from Mars, similar in composition to the 1977 Antartica find. 'The meteorite would have been blasted off the Red Planet by an impact and may hold clues to Mars' watery past... scientists say the fragments are magmatic rocks. Magmatism is the main process by which water moves from the core of planets to their surface.'"
We have rovers on Mars collecting data that has no chance of being contaminated by a meteorite impact, travel through space and terrestrial processes.
I'll take data from the horse's mouth.
Rock on, Rovers!
What you are calling "science" is really science reporting. Science reporting summarizes the real science and leaves out the qualifiers and statistical information from the original published peer-reviewed work. Science reporting frequently offers broad and sweeping conclusions of hard fact from original work that only reports on evidence that such a conclusion may be true. Even science textbooks are basically summaries of the original research and omit the nuances. Science reporting is a hollow shell of real science.
To understand what the scientists are really saying you have to go read and understand the original articles.
Imagine a large asteroid hitting mars. There will be BILLIONS of pieces sent into an orbit similar to mars, many of which will then be gravtationally tossed into other orbits by mars itself. It's not hard to imagine many many of these eventually landing on earth within the billion years or so since then.
There are alot more than 6 pieces that have been found, these two people just happen to collect ALOT of meteorites and happen to know how to recognize a martian one. Of course it sounds like too much coincidence to be true when you think only 6 have hit earth and all been found by the same people, but in reality thousands and probably millions have hit earth, and many have been found and not recognized for what they are. It only makes sense that the people who know how to recognize them would find the most.
