Find a comet Martian water

Scientists expressed surprise of carbonic color meteor from Mars had landed in the Sahara desert. A year of analysis has revealed that this rock is very different from other Martian comets, not only for being older than most of them, but because they also contain more water.
Omar meteor estimated -oho ball-sized Bespol- about two million years, a remarkably resembles volcanic rocks you look at Mrkpta Spirit and Opportunity Committees of the Agency Aeronautics and Space Administration (NASA) on the surface of Mars.
It is noteworthy that most of the space rocks that fall to the ground -kalnaazak- come in what is known asteroid belt located between Mars and Jupiter, which revolves around the sun, but a number of them can be traced to the moon and Mars. Scientists believe that an asteroid or something big cause another hit Mars in resolving the rocks and sent to space, and from time to time each fall, breaking the Earth's atmosphere.
There are about 65 Martian rock taken from the ground, mostly in Antarctica or the Sahara. The oldest dates back to 4.5 billion years to a time when Mars warmer and wetter. There are about six Martian meteorites estimated age of about 1.3 billion years old, and the rest by about 600 million years old or younger.
The latest meteor -oiday N.W.A 7034 and nicknamed Black America beauty has donated to the University of New Mexico by the US brought him from a Moroccan meteorite dealer last year.
The researchers conducted a series of tests on the meteorite and stressed, upon the Tercepth- he came to Earth from Mars. Old and appreciated by about 1.2 billion years old, this meteorite is the second oldest known Martian meteorite formed from volcanic eruption.
There is evidence that the composition has changed because of the water. Although the quantity arising during testing at high temperatures were minimal -nho six thousand part in Alumblyon- it was still much larger than the other Martian meteorites. Scientists have noted that there is interaction with the water near the surface during a period of time when the planet was dry and mostly dirt.
And is currently being further tests to determine the length of time in which this rock swam in space, and the period spent sitting in the Sahara desert.
