Scientists have confirmed that 7 pounds of material from Mars fell in Morocco last July. This is only the fifth time in history that scientists have chemically confirmed Martian meteorite nature. Previous such "souls" was discovered in 1962 on the heels and therefore was not contaminated earth compounds.
Fallen stuff is incredibly expensive - it cost ten times the gold. This is due to the fact that not even a single Martian probe failed to return Martian material back to Earth. The only source of these stones - like rain.
These meteorites may be the key to our search for life on Mars. The fireball was detected in the sky six months ago, but the stones have been found in North Africa until the end of December.
The Special Committee, composed of scientists specializing in meteorites, which included experts from NASA, confirmed the test results Tuesday. They came to the conclusion that 7 pounds of meteorite material came from Mars. The largest of the stones weighs 900 grams. The total weight of all the Martian rocks on Earth is less than 110 pounds.
The astronomers believe that millions of years ago something big has got to Mars and launched these rocks into space. After a long journey through the solar system, these stones hit the Earth’s atmosphere, broke up into smaller pieces. Most other Martian meteorites before being discovered, were in the earth for millions, or at least a dozen years, because of what they were polluted earthly matter and life forms. These new rocks, in this respect, much cleaner. Previous case where Martian meteorites fell to Earth and was found fresh, occurred in 1962.
Most of the Martian rocks on Earth has been found in Antarctica or the desert. They are very similar to Earth rocks, so in case of contact with other places, they blend in with the environment, and finding them is impossible.
Scientists identify Martian meteorites on their age. Because Mars is extremely geologically active, the material it is usually much younger. Its age is estimated in millions of years, not hundreds of millions, as is the case with the lunar material or asteroids.
Announcing the appointment and names meteorites, termed Tissint was conducted by the International Society for the Study of meteorites and planets, which includes 950 scientists that confirms and names meteorites.
Meteorite dealer Darryl Pitt, who found and sold the meteorite, said that the cost is from 11 000 to 22 500 dollars per ounce (28.3 grams). He has already sold most of their stock. At that price, the new Martian rock costs 10 times more expensive than gold.
"From a scientific point of view, they are priceless," - said the expert on meteorites from the University of Alberta, Chris Hurd. "This is a very interesting patterns. They are very rare, very fresh and aesthetically appealing."
Martian meteorites fall to Earth with a frequency of once every 50 years: in 1815 in France, 1865 in India, 1911 in Egypt and 1962 in Nigeria.
