Sealed off for millions of years beneath an almost impenetrable layer of ice, Lake Vostok has kept a vast archive of ancient history waiting for just the right moment to reveal itself. Here is a unique closed ecosystem captured in time below four kilometers of ice. Saved from environmental contamination, its water has been isolated [...]

No eldritch, mocking cries of "Tekeli-li! Tekeli-li!" have been reportedly heard on the site... Nor yet any mention of albino penquins. Must be a conspiracy! Especially given that the natzis where also there and there's no mention of them in the official reports either:

Actually I'm pretty sure this is how "The Thing" comes to fruition...only Kurt Russel can save us now.

Seriously this is awesome news. I hope they find out some interesting stuff. This is knowledge that can be used for future space endeavors...though I would assume that endeavor would be to Enceladus and not Europa as the Doctor in the article states.

The phrasing is a little incomplete...are they referring to the "quantity of oxygen" in the water sample?.....because the atmosphere on Earth is ~ 18% oxygen, and you can't get 10-20 times that .

The presence of oxygen in the lake water is a real surprise to me. I would have thought that all of the oxygen would have been consumed ages ago by the oxidation of lakebed sediments.

Here's another article in the Washington Post:

http://www.washingtonpost.com/world/europe/russia-reaches-freshwater-lake-buried-under-miles-of-antarctic-ice-for-millions-of-years/2012/02/08/gIQAL44hyQ_story.html

This contains some interesting facts reflecting on plans to drill to suspected oceans beneath the surface of either Saturnís moon Enceladus and Jupiterís moon Europa.


The article states that it took more than two decades to complete the drilling operation here on Earth. In spite of the performance of Spirit and Odyssey, it is not serious to believe that such an operation could be accomplished at the distance of either Jupiter or Saturn. And this operation only had to drill 3.8 kilometers; the estimates for Enceladus and Europa range from5 to 50 or 100 kilometers.

It also stated that 60 metric tons of lubricants and antifreeze was consumed in the process. Ignoring the weight of the actual drilling, scientific, and communication equipment, the Saturn V rocket would be able to place this weight into low earth orbit, but not inject it into a path to our moon. The Space Shuttle would not be able to place even half this weight into low earth orbit.
