The Long Duration Balloon (LDB) carrying the scientific payload known as CREAM. CREAM (Cosmic Ray Energetics and Mass) is designed to study the origins of cosmic rays, measuring their composition from protons to iron nuclei. The goal is to observe cosmic-ray spectral features and/or abundance changes as a function of energy that might signify a limit to supernova acceleration. This balloon will circumnavigate Antarctica in the stratosphere, returning to the launch site due to circumpolar winds that occur in mid-December. Visit the CREAM website to learn more.
