The GEOS and ISEE (International Sun Earth Explorers) 1 and 2 spacecraft were central spacecraft in the International Magnetospheric Study (IMS) initiated in 1976. These missions are reviewed with the aim of improvements for the Cluster mission. These spacecrafts had new instruments based on the experience of the first years in magnetospheric research, and the IMS aimed at comparing data from many instruments on spacecraft and between many different spacecraft and ground observations. Valuable science was produced on the basis of the data from these missions. However some of the more ambitious aims were not reached, partly because the technical means (computers, networks and storage media) were not sufficiently developed to deal with such a tremendous task. Certain organizational aspects could also have been improved.
