Peter Doran on seeking life under Europa’s ice

EarthSky spoke to Peter Doran of the University of Illinois at Chicago. He’s principal investigator of the ENDURANCE project, whose robotic submarine will seek organic molecules beneath ice-covered Lake Bonney in Antarctica starting in late 2008. We asked Professor Doran what life on Europa might be like.
Peter Doran: On Europa, we don’t know enough to be able to answer that question. There may be higher orders, because there may be things like geothermal hot springs coming out of the vents, coming out of the bottom of the ocean.
By higher orders, Doran means higher life forms such as those found in and near earthly hot springs.
Peter Doran: And that would supply a lot of material and energy into the system where you may be able to support those higher orders. So if those are there, yeah, you might find some funny Europan fish.
But Doran said microbial life under Europa’s ice would probably be more likely. And as to why he and others want to look for life in strange places like Antarctica and Europa. . .
Peter Doran: For me, it’s the most important question that we can ask. Did life evolve elsewhere? And it sort of puts us in perspective.
If all goes well with the test of the ENDURANCE project in Antarctica in 2008, the robot sub will create a three-dimensional map of water conditions such as temperature and salinity. It’ll be able to detect organic molecules, signs of life in the depths of this Antarctic lake.
Peter Doran: It’s one of the last unexplored aquatic environments on Earth, really. And it’s such a deep lake, it’s under so much ice, that we’re really not sure if life can really exist there. So we’re interested in going down to see if the system that’s been isolated for perhaps millions of years could harbor an ecosystem that we can go and measure. And so the Endurance project is the first step towards that.

Mr.Associate Professor, For there to be oil in the Arctic National wildlife area,there had to be large amounts of plants,its vegetable oil,Dude, vegetable oil. For there to be mammoths found frozen in Siberia,with seeds in their mouth and stomach and the meat still intact,there had to be enough heat and vegetation for them to be cruising through there.Lots of things happen on planets,happy hunting.
I remember reading about the lakes in Antaractica. I have read of life existing where no one though life could exist so life will find a way.
Are you crazy, guys? Are you going to live on the Red Planet or Europa?
Don’t you think, that it’s necessary to look after your own planet first instead of seeking life tracks on others? And what about cutting down CO2 emissions in Al industry? The ice sheets in Antarctica won’t wait up for you space searching.
They can be slipped down by the world’s ocean. And what is then?.. Will you need your collected space data on the ocean’s bed?
