A cumulative flight duration of more than 100 days has been achieved by the balloon-borne Cosmic Ray Energetics And Mass (CREAM) experiment, which has flown four times in Antarctica. The instrument is configured with complementary and redundant particle detectors to extend direct measurements of cosmic-ray composition to the highest energies practical with balloon carriers. All elements from protons to Fe nuclei are separated with excellent charge resolution, and data have been collected over a wide energy range from ~ 1010 to ~ 1015 eV.

Abstract
A cumulative flight duration of more than 100 days has been achieved by the balloon-borne Cosmic Ray Energetics And Mass (CREAM) experiment, which has flown four times in Antarctica. The instrument is configured with complementary and redundant particle detectors to extend direct measurements of cosmic-ray composition to the highest energies practical with balloon carriers. All elements from protons to Fe nuclei are separated with excellent charge resolution, and data have been collected over a wide energy range from ~ 1010 to ~ 1015 eV. These direct measurements in near-space provide an overlap with the abundant indirect measurements made from the ground. Instruments recovered from the previous flights are being refurbished and integrated in preparation for the fifth launch. The project status including results from the ongoing analysis and future plans will be presented.
