Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
The purpose of this chapter was to attempt to quantify as closely as possible the risk posed to spacefarers and to the planet Earth by space dangers. The empirical record of space objects striking the Earth was examined, specifically with respect to NEOs, asteroids, meteors and comets. Potential threats from supernovas, black holes, space debris and gamma rays were also quantified. An overall aggregate risk assessment was provided.
