Abstract
The instrument PAMELA, in orbit since June 15th, 2006 on board the Russian satellite Resurs DK1, is delivering to ground 16 Gigabytes of data per day. The apparatus is designed to study charged particles in the cosmic radiation, with a particular focus on antiparticles; the combination of a magnetic spectrometer and different detectors - indeed - Allows antiparticles to be reliably identified from a large background of other charged particles. New results on the antiproton-to-proton and positron-to-all-electron ratios over a wide energy range (1 - 100 GeV) have been recently released by the PAMELA collaboration, and will be summarized in this paper.
