The famous Martian meteorite ALH 84001 uncovered in 1992 in Antarctica contain fossil traces of microorganisms lived anciently on Mars. To anticipate
the news, about to publication on the scientific magazine Geochemistry ET Cosmochimica Acta, is the site American specialized in spatial activities
"SpaceflightNow"
The meteorite, Allen Hills or ALH 84001, is famous for a long time to the students, than they are analyzing since first years to it ` 90. However
nobody up to now had confirmed officially found traces fossils. It has made by the Astrobiology group coordinated from Kathie Thomas Keprta, of the
Johnson Space Center of NASA, using a electron microscope to high resolution that has afforded to inside analyze to the discs of carbonate and the
small letters magnetite present crystals of the meteorite. According to the authors of the search the fossil bacteria are enclosed in magnetite
crystals, produced from the same bacteria.
NASA, still reports to the site American, is prepared to announce the discovery in the next few days. The first observations made on the same
meteorite were announced in 7 August 1996 from NASA and from the White House and in that occasion then the president USA Bill Clinton had promised
that the searches in this within would have gone ahead, but other studies had refuted and on HAL84001 the oblivion had fallen for 10 years.

“There are fossil microorganisms on Mars! From geologist I would know astonished if they had not seen them”: it comments so the news Vincenzo
Rizzo, of the department of Sciences of the Earth of the university of Florence and the National Research Council (Cnr), that it has described
recently Martian fossil formations on the International Journal of Astrobiology and a its new study is about to publication on an other international
scientific magazine. The searches of I raise, lead in collaboration with Nicholas Cantasano, of the Institute for Agricultural and Forest Sistems of
the Mediterranean (Isafom) of the Cnr, transmitted collections and to Earth from the probe of NASA Opportunity are based on the analysis of the
images. They regard two types of formations: the spheres nicknamed “mirtilli”, characterized for a long time in the zone of the called planet
Meridians Planum, the great plain to South of the Martian equator. "The spheres", said the two Italian investigators, “could be organosedimentarie
structures, probably produced from microorganisms”. Their origin could find an explanation similar to that of the structures calls stromatoliti
presents on the Earth and formed thinnest sheets in which ancient microorganisms are trapped, or animals (colonies of bacteria) or vegetables
(microscopic alghe). However, it finds I raise, “is difficult to make any parallel between Martian microfossils and any form of microscopic life on
the Earth”.
Now is official: THERE WAS LIFE ON MARS!
AND MAYBE STILL NOW!
