The purpose of these Summer Schools, held every second summer onboard a river cruise ship on the Volga and organised jointly by the Radiophysical Research Institute (NIRFI), Nizhniy Novgorod, Russia and the Uppsala Division of the Swedish Institute of Space Physics (IRFU), Uppsala, Sweden, is to give an introduction to modern space plasma physics by bringing together experienced researchers, young scientists and scholars in astrophysics, space physics and plasma physics for a fruitful exchange of ideas across areas of interest, language, culture and age barriers.
The topics covered include linear and non-linear plasma physics, waves and radiation phenomena in plasma, waves in random media and turbulence, planetary, solar and stellar coronal plasma, plasma under extreme conditions in space, space plasma radio emission, radio methods for investigating space plasma environments, and the use of the Earth's ionosphere and magnetosphere as a space plasma laboratory for model experiments simulating phenomena in other plasma environments.

In October 1995, ESA decided to study such an infrared interferometer as an option for its Interferometer Cornerstone. The Darwin and Edison teams have combined to promote the selection by ESA of this option.
