'Find adds to strife on Mars'
By Robert Uhlig, Technology Correspondent
THE existence of life on Mars has been thrown into further doubt after
scientists found that two of the four lines of indirect evidence
supporting the meteorite finding can be explained by non-biological
processes.
When Nasa announced it suspected early extra-terrestrial microbial life
on Martian meteorite ALH 84001, it based its claims on the fact that
four compounds found inside the meteorite could be produced only by
living organisms.
Most damaging of all to supporters of the Martian life theory is the
suggestion by geoscientists in America that magnetite crystals inside
the meteorite, assumed to be the product of bacteria, were not
produced by a biogenic process.
"The biological explanation is becoming less and less plausible," said
John Kerridge, a planetary scientist at the University of California
at San Diego, who is familiar with the studies published or about to
be published in the journal Geochimica et Cosmochimica Acta.
San Diego scientists also found organic molecules called polycyclic
aromatic hydrocarbons in Antarctic ice were the same as those inside
the meteorite's globules. They were also found in other meteorites
that did not come from Mars.
