Ballistic comet exploration mission options

Abstract

Trajectory options and mission opportunities of cometary rendezvous missions begining in 1990 are explored. The study is constrained to the capabilities of the Mariner Mark II multi-mission spacecraft, Shuttle launch and Centaur G-prime boost. The mission would be targeted at collecting an atomized sample, near the comet perihelion, and returning the sample for analysis. Mission trajectories, launch dates, payload masses and flight durations are provided for 13 comets. All missions would take from 4-8 yr and deliver a 600-2000 kg payload. A survey of mission opportunities involving Jupiter gravity assists is also presented.
