Shuttle-launched multi-comet mission 1985

A low-cost multi-comet intercept mission with a launch in March 1985 is proposed. Two cometary spacecraft of identical design will be placed into a low earth parking orbit using a single Shuttle launch vehicle. Solid kick stages will then be used to boost each spacecraft into its required interplanetary trajectory. It is planned to have one spacecraft intercept comet Giacobini-Zinner in September 1985 and then go on to comet Borrelly with an encounter in December 1987. Earth swingby maneuvers will be used to achieve the double cometary intercept. The other spacecraft will be targeted for a pre-perihelion encounter with Halley's comet in December 1985.
