Title: PAMELA - an experiment searching for dark matter with cosmic antiparticles

Abstract:  The PAMELA satellite experiment was launched into low earth orbit on June 15th 2006 for a 3 year mission. The combination of a permanent magnet silicon strip spectrometer, and a silicon-tungsten imaging calorimeter allows precision studies of the charged cosmic radiation to be conducted over a wide energy range (~100 MeV - ~200 GeV). The primary scientific goal is to search for dark matter particle annihilations by measuring the energy spectra of cosmic ray antiparticles. The status of the PAMELA experiment will be reviewed with a particular focus on recent results concerning cosmic ray antiprotons and positrons.
