The balloon, following circulation of winds high quote, will sail around the ice continent for about three weeks. During this time, data of great scientific interest will be gathered. These data concern flows of charged particles of highest energy (cosmic rays) coming from Space.
Cream experiment was conceived in particular to investigate the origin of cosmic rays and their acceleration mechanisms: two questions that are still waiting for a definite answer, in spite of the enormous advancements carried out in this field since 1912. At that time Victor Hess, thanks to his pioneer balloon flights, was the first to show the existence of radiation coming from Space.
