Quantitative Risk Estimates of Space Dangers
Pp. 314-323 (10)
Dirk C. Gibson
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.
