Missions to Comets

Interest is growing as Halley s Comet continues to draw in toward the sun. Already there have been trial runs in observing the much fainter Crommelin's Comet, and of course several space-probes will be launched towards Halley, to rendezvous with the comet in March 1986. Patrick Moore discusses these developments with Dr John Davies of Newcastle University, and explains what British observers may be able to see.
