Scientific paper

The paper discusses modest comet or asteroid missions which require a launch energy of 20 sq km/sq s or less and allow only navigational post launch delta-V's. Objects with perihelia of 2.0 AU are available directly after an earth launch; this distance is extended to 2.4 AU by a Mars gravity assist and the flyby speeds can be reduced. Twenty-one asteroid targets have been identified for Mars gravity assist trajectories using the 1986 Mars opportunity. Two asteroids on direct trajectories with low asteroid flyby speeds and four Mars gravity assist targets are identified as possible rendezvous targets for launches with capability of carrying the rendezvous delta-V engines.
