subsurface oceans, we d like to think that with water and energy sources and chemical nutrients or the chemical ingredients that are necessary for life we ll get microbial life on other planets like that. jon: 128 degrees below zero at times or the coldest temperature ever recorded on earth, yeah, that would be pretty difficult conditions in which to work. i guess part of the problem is the simple matter that it is so cold they get this drill in there, and it freezes up again. i mean, the hole fills up again and freezes. true. and they ve got to keep this drill string or this drill bore open for over two miles of ice, 13,000 feet down to the lake. and then you ve got to penetrate into this pristine lake water without injecting, as was told us, contaminants into that hole. so it s a very carefully-planned effort or more than ten years to make it this far. next season we ll get actual samples out of the bore hole to see if there is bacterial life or something more complex.
