Dear Colleagues!

We are starting to prepare the next XXVI Symposium dedicated to the 60th anniversary of the first flight into space by Yu.A. Gagarin. In the coming days we will start sending out newsletters.

P.S. In connection with the changed conditions for holding international events, we apologize for the change in the composition of the Organizing Committee.

P.P.S. The collection of papers for 2020 is available at open access eLibrary . And everyone else from 2005 too.

Organizing Committee of the Symposium.
