Comet Hartley - fast approaching meeting

24 Oct 2010

At www.sciencedaily.com/releases/2010/10/101022113117.htm is a report on the space mission  scheduled to have a close encounter with Comet Hartley in November. However, even now observations indicate the comet is not behaving as it should do in respect of the consensus model of comet behaviour. It was seen to increase the release of cyanide fourfold over an 8 day period in September - without an increase in dust emissions. It is not known why this happened.
