Cosmic Shooting Gallery

An article in the Observatory 125 (2005) pages 319-122, 'Earth in the Cosmic Shooting Gallery' by DJ Asher, Mark Bailey, V Emil'yanenkar abd Bill Napier (see www.arm.ac.uk/preprints/455.pdf) claims the terrestrial impact rate appears to be substantially higher than current NEO population models imply but is consistent with a significant unsee asteroid and cometary contribution to the hazard. A bit of doomsaying but interesting in how it might have impinged on the past. All but the Russian astronomer are well known in SIS circles (as speakers at meetings or conferences as well as articles published by the society). We should perhaps try to set up a connection with Russians interested in this field of research.
