... The author attempts to approach the problem from the positions of systems analysis with account for the ideological grounds and history of space activities in Russia and abroad, comparing its current interpretation with the initial goals posed by leading theoreticians and practitioners who stood at the cradle of the space exploration era. ... The space systems recognized in Russia as priority projects are largely developed with violations of the systems approach principles. ...

... Three energetic mechanisms are considered: multiple supernova explosions (SNe), a hypernova explosion associated with a gamma ray burst (GRB), and the vertical impact of a high velocity cloud (HVC). ... As a consequence, multiple SNe form rings with a high ring-to-center contrast K < 100 in the HI column density, whereas single hypernova explosions form rings with K < 10. ... Our simulations show (see Fig. 6) that both multiple SNe and single hypernovae may form rings of up to 2 kpc in diameter. ...
