Russian Scientists May Have Drilled into Previously Untouched Subglacial Lake
International scientists teeter between excitement and concern after 
reports from Russian news agency RIA Novosti that Russian scientists 
have drilled into the untouched Lake Vostok, 2.2 miles below the surface
 of Antarctica.
The lake, discovered in the mid-1990s, is the world’s third largest 
and could hold a vast amount of scientific data, both about how lakes 
function below the surface of the ice in Antarctica and about the 
possibility of discovering previously unknown life forms. That is, if 
the kerosene, Freon and other chemicals used in the 20-year drilling 
process didn’t leak into the water and ice and contaminate the area.
Crews have tried to reach the lake for over two decades, but the 
going is slow, with the limited mobility of transportation in and out of
 the area and machinery unable to work most of the year due to the 
astonishingly cold temperatures.
While no formal announcement has yet been made about the 
breakthrough, scientists around the world say that if the Russians have 
indeed tapped into the lake, the body of water could completely change 
the way research gets conducted in Antarctica. Learning about conditions
 in lakes glossed over with ice could also help inform scientists about 
conditions on other planets.
The U.S. and Britain will join the ice drilling in search of 
subglacial lakes this year, as the search for information continues on 
how our planet’s largest reservoir of fresh water (as ice and subglacial
 lakes) changes and reacts to climate conditions. With more than 200 
lakes beneath the ice, there’s plenty of drilling left to be done.
 
Russians drill into Lake Vostok, begin search for life under Antartica’s surface

Thursday, February 9, 1:45 PM
Scientists are taking the search for life in extreme environments to the ends of Earth and beyond. On Wednesday Russian scientists announced they had reached Lake Vostok, a subglacial lake under Antarctica. As AP reported:
Russian researchers reported Wednesday that they had reached Lake Vostok, a pristine body of water untouched by light or wind for about 20 million years. They want to know what type of microbial life — bacteria too small to see — might exist there.
