“Comet/Asteroid Impacts and Human Society” sounds like a good addition to Firestones, Cosmic Catastrophe book [I left it in the car and am having a senior momemt on the full title]. Another worthwhile book is “Comet” by Carl Sagan and Ann Druyan, revised in 1997. Also “Impact Earth: Asteroids, Comets and Meteoroids: The Growing Threat” by Austen Atkinson, 1999.
One problem the last book points out is that the southern hemisphere has only one tenth the amount of searching that is going on in the northern hemisphere. Will the Canadian satellite help this problem, or should be be urging South Africa, Argentina or Brazil to also send out a satellite?
The s hemisphere lack is one reason Australia plays such a big role in the search. :’)
