Abstract
The early accomplishments in space are outlined with emphasis upon particle and field research. The four major groups of energetic charged particles-primary cosmic rays, energetic solar particles, the solar wind, and charged particles in geomagnetically trapped orbits near the earth are discussed and further investigation of Galactic cosmic rays, energetic solar flare particles, the solar plasma and the trapped radiation is recommended. The primary NASA launch vehicles of the present and the future are related to the experiments proposed. Some of the spacecraft planned for the future are also described.
