This Summer School was organized by the Preparatory Commission (COPERS) of the European Space Research Organisation (ESRO). It was the first time that such a summer course was held in Europe on a subject of space physics. Thanks to an invitation from the Austrian Government these lectures were given in the College House of Alpbach, Tyrol. Eight outstanding European scientists each presented five two-hour lectures on topics covering the region between the Sun and the Earth. The courses contained the physics of the Sun, the Interplanetary Medium and Trapped Radiation, the Ionosphere and High Latitude Phenomena. Furthermore, a course on space instrumentation was given. Sixty students were selected to attend the courses.
