A large international team of scientists and drilling technicians will be working throughout the austral summer to continue testing with the world's largest scientific instrument, the in-ice IceCube Neutrino Detector. Neutrinos are incredibly common (about 10 million pass through your body as you read this) subatomic particles that have no electric charge and almost no mass. They are created by radioactive decay and nuclear reactions, such as those on the Sun and other stars.
