Abstract

Direct measurements of the charged cosmic radiation (cosmic ray) impinging on Earth, play an essential role to get information of the acceleration and propagation mechanism by providing the relative abundance and the energy spectra. Observations, using balloon-borne detector, in Japan were historically achieved especially in field of the high energy electrons and hadrons. Since 2000, the cosmic ray observation in worldwide has done a remarkable progress by development of the detectors with high-technology electronics system and by success of the long duration ballooning, such as, in Antarctica. Further space observations planned at International Space Station will challenge to resolve the puzzles of the dark matter and the anti-matter in universe. The achievements of the direct observations by present days and the future prospect will briefly be reviewed in this article.
