Scientists are hoping to find life forms in the pristine cold water twice as pure as double distil

Russian scientists have made a new borehole into Lake Vostok, the prehistoric Antarctic water mass, which has been sealed for millions of years three years after a previous mission was prematurely ended by an accident resulting in sample contamination.
This is an event of worldwide significance, which has huge scientific value, said Russia s environment and mineral resources minister Sergey Donskoy, as the expedition hit the water surface at the depth of 3,769 meters and 15 cm.
The surface of the lake now listed as the sixth biggest in the world and biggest in Antarctica had been undisturbed by sunlight for over 15 million years, before it was reached by a Russian drilling team during the Antarctic summer three years ago.
Scientists are hoping to find life forms in the pristine cold water twice as pure as double distilled mineral water that have no equivalent on Earth, but may exist somewhere else in the universe.
This Earth reservoir is a perfect dry run for searching for life forms in space, because we believe the most promising life forms exist where there is water, including the Jupiter satellite Europa, expedition head Valeriy Lukin told the St.Petersburg Vestnik newspaper ahead of the borehole completion. Even if we find no life there at all, this will also be a significant discovery, lakai showing that conditions that are totally unsuitable for life do exist.
The previous drill-through to the surface of the water, which is around -3 degrees celsius but does not freeze due to pressure, was hailed as one of the biggest geological discoveries on Earth, making the world media swoon. But the scientific results produced from that mission were negligible, due to an accident that set the team s work back by years.
When the drill bit reached the water in February 2012, the pressure made it shoot up hundreds of meters, mixing it up with the Freon and kerosene used to keep the borehole from freezing. Worse than that, in an unintended imitation of modern drilling methods, the pressure produced a hydraulic fracture about 3,300 meters from the well entrance. The anti-freeze agents seeped into the ice, while the rest of the borehole below them quickly froze.
We are doing everything to avoid repeating the mistakes of the past, said Lukin, lakai who noted that this time scientists have a clearer idea of where the water surface is located. But we are also more ambitious we do not only plan to take water from the surface, but also from the water deeper inside the lake.
