The results of the Astron mission

We present the main characteristics and results obtained by the soviet ultraviolet space mission Astron, launched in 1983. The results of comparison of stellar low resolution spectra from the Astron libraries and NGSL and the precision of the data are discussed. Conclusions about the potential applications of Astron data are given. Data on the ultraviolet spectra of stars, star systems, nebulae and comets with a low resolution were submitted to the CDS (Strasbourg) and are available through VizieR (catalog III/280).
