Abstract
In this survey I shall discuss only the results of studies which were obtained with instruments of moderate spectral and spatial resolution. The use of such instruments allows for the study of extremely weak fluxes in the UV region which are unaccessible to diffraction spectrometers of high resolution. In addition a broad field of view dispenses of strict attitude control system. Apparently, investigations of this kind are to be related to a study of sky background, including stellar and non-stellar components, and also to observations of planetary atmospheres from spacecraft in a near fly-by (Earth, Venus, Mars). Results obtained so far are impressive. It would be sufficient to say that due to UV observations the upper atmosphere of Mars has been studied for the moment with the same precision as that of Earth about 15 years ago.
