Phoenix Finds Water In Form of Ice on Mars, Search For Life on Mars Begins [Are We On the Brink of A Major Scientific Discovery?]

According to exciting news just hitting the wires NASA's Phoenix has
purportedly located what scientists are certain is ice just under the
surface of Mars which appears to have been discovered thanks to the
Phoenix Lander's twelve retrorockets - used to slow the descent of the
Phoenix prior to touchdown on the Martian surface - blowing away several
inches of the surface to reveal what is believed to be an extended table
of ice.

Should the 'shiny and smooth' material prove to be ice (and the
programme's scientists are convinced that the material unearthed is
exactly this) then this would serve as a strong indicator that liquid
water - which is essential for life as we know it - could have existed
many millions of years ago when Mars was warmer which, in turn, could
suggest that Mars may once have sustained a habitable environment where
life could have existed.

“Ice is a great preserver,” Peter Smith of the University of
Arizona, Tucson said during a conference call with reporters, “and
it’s one of the building blocks of life.” Though whether the
material found, assuming that it is ice, will harvest any evidence of
past life on Mars once examined by Phoenix remains open to speculation.
With this in mind, Phoenix will begin examining the ice this week, with
samples being analysed onboard the craft to access the salinity and
chemistry of the Martian ice.

Will Phoenix make the discovery that life did indeed exist on Mars at
some point in the past, as many scientists have long since speculated?
Time will tell, but there's no doubt that the Phoenix could be on the
brink of what would undoubtedly be one of, if not the, most major
scientific discoveries of all time (just a shame that Arthur C. Clarke
isn't around to hear the news should some indicator be found).
