ABSTRACT
Messages about new scientific discoveries or new technological achievements reach us frequently. Often these come from the field of astronomy or space science. New instruments of observation have been developed using rockets, satellites or space shuttles. The exploration of our solar system has opened up a new era of scientific investigation. The development of data communication techniques has made it possible for us on Earth to stay in contact not only with astronauts making more and more distant trajectories in their spacecraft, but also with observing instruments and recorders on unmanned spacecraft sailing further and further out in the archipelago of remote planets, passing through belts of asteroids and the continuously blowing solar wind, measuring parameters of distant magnetospheres and studying magnetic fields and space plasmas.
