Wow. After following this for years, I'm a tad embarrassed to have missed the announcement by a couple of months, but here we have it:
Russians drill into previously untouched Lake Vostok below Antarctic glacier
The recent news of Cameron's visit to the Mariana Trench reminded me of the Lake Vostok quest, so I had to go searching for the latest. In a nutshell, they hope to be analyzing water samples and sending in robots later this year. Stay tuned! Discovery of life in such a place would surely send speculation about life on Europa into mega-overdrive.
Which would be pretty neat.
