… The collaborative philosophy will indeed yield added value …
This is from Physiology and Biochemistry of Extremophiles edited by Charles Gerday and Nicolas Glansdorff (2007):
… The ice sheet has existed for 15 million years or more, isolating the lake from the atmosphere. The origins of Lake Vostok may thus date back to the Miocene.
[line break added] The residence time of the lake water has been calculated to be in the range 55, 000 to 110,000 years. Estimates for the age of the water body range from 1 million years to 15 million years; it is a “fossil ambient” which evolved during a very long time span in almost total isolation from the biosphere.
… After reaching the water, it would be sad to see studies on Lake Vostok deprived of the essential contribution to biology, or — even worse — to see the beginning of lengthy disputes on whether a microorganism found in the lake is a contaminant or not. However, we are confident that the science community will succeed in preserving this scientific treasure.
… The danger of irreversibly contaminating extraterrestrial bodies with biological material coming from Earth is an even greater concern for space missions, and again, this calls for extreme care. Consequently, safe drilling and appropriate experimental procedures not only are a must for accessing the ecosystems of subglacial lakes but will have the added value of providing essential codes of action in astrobiology.
… All of these great challenges are in common with subglacial-lake explorations and will entail enormous logistic efforts and are hard for a single country to afford, again calling for multinational and multidisciplinary projects. The collaborative philosophy will indeed yield added value to these exciting ventures.
