Lake Vostok: Poland Springs – Eat Your Heart Out

There is a host of research bases located in Antarctica and they are run by a number of different countries, including the United States, China and Russia.  People at these stations study everything from weather to aeronomy, the study of the upper atmospheric regions of the Earth and other planets.  Antarctica is a chosen spot for research because the region is probably the most unspoiled area in the world with the cleanest air on earth.

The oldest station is Mawson Station.  It’s Australia’s oldest continuously inhabited Antarctic station having run since 1954.

There are hundreds of subglacial lakes of varying sizes under Antarctica’s miles-thick sheet of ice.  The Russians are the first to drill into one of those lakes.  Lake Vostok is under the Russian’s Vostok Research Station and on Sunday, 2/5/12, the Russians tapped into the lake.  There was a mixture of anticipation and trepidation within the scientific community leading up to the accomplishment.

The Russians used a combination of chemicals to prevent the five inch diameter drill hole from refreezing as they drilled.  Bear in mind, the coldest temperature ever recorded, -128.6 degree Fahrenheit below zero, was recorded at Vostok Station.  The use of the chemicals had some scientists concerned about the possibility of contaminating the lake.  To reduce the chance of contamination, the Russians completed the project, sans chemicals, by heating the drill.  The Huffington Post reported that the lake’s water pressure pushed any drilling liquids away from the lake.

Unfortunately, winter has arrived in Antarctica and the exploration of Lake Vostok has been suspended.

This is an exciting accomplishment.  The subglacial lakes are considered pristine environments because they haven’t been exposed to Earth’s atmosphere in millions of years.  Scientists wonder if life exists in any of these waters.  If so, they theorize there’s a chance that life could be present in the frigid waters of Jupiter’s moons.

I’m hopeful that life, even a single celled organism, is found in a sample from one of these lakes.  Maybe, that will help fuel some renewed interest in space.  If there’s even a remote possibility that there’s life “out there,” we need find it.

What do you think; does life in an earthly subglacial lake equate to alien life on a distant planet?
