Exploring Antarctica

dargaud writes "There will soon be some firsts on the high Antarctic plateau: after getting 150km from it last year a Chinese expedition plans on reaching Dome A, the highest part of the Antarctic ice sheet (4200m), farthest to reach and coldest place on Earth, untrodden yet. Then in a few months the French-Italian station of Concordia at Dome C (3200m) will open year-round for its first winter-over, of which I will be part. The location of these ice domes make them great for atmospheric physics, glaciology, astronomy and more. Big projects are getting interested in Antarctica again, just in time for the International Polar Year of 2007, 50 years after the first one."

IceCube starting up

[EigenHombre]

There is always a tremendous amount of science going on in Antarctica, but this year will mark the first deployment of sensors in the IceCube neutrino detector at the South Pole, one of the largest Antarctic science projects to date.

If all goes well this Austral Summer, IceCube will deploy four "strings," each with 60 light sensors attached, at a depth of about 2 km. Subsequent years will deploy more sensors until a total of 4800 is reached, making the cubic-kilometer sized detector one of the largest on Earth.

IceCube's quarry is primarily neutrinos of extraterrestrial origin. For the uninitiated, neutrinos are extremely elusive subatomic particles produced by high energy interactions. Candidate sources include the supermassive black holes at the heart of so-called "Active Galactic Nuclei", dark matter, and the mysterious Gamma Ray Bursts.
