Ballistic aspects of comet studies

Various aspects of spaceborne studies of comets are examined with particular emphasis on investigations of Halley's comet; attention is given to conditions for spaceborne observations of comets on the earth-Venus-Halley's comet transfer trajectory. It is proposed that scientific instruments be implemented for the investigation of comets from distances of the order of 50-150 million kilometers; the installation of these instruments on numerous earth satellites and interplanetary probes would make it possible to create a widespread space network for the regular remote monitoring of comets. This network would facilitate the discovery of new comets, especially those with parabolic orbits.
