Inner Solar System Rendezvous Mars Sample Return  grab & go optimal for solar sailing 5 – 6 year mission v's ~2 years for equivalent chemical mission Venus Sample Return  Similar to MRS but with increased launch mass sensitivity 1000 m 2 sail for sample return leg offers potential launch cost saving Mercury and Small Body Sample Return  Truly high-energy transfer trajectories Only low-thrust propulsion systems offer viable mission concepts Solar sailing offering potential benefits  Small Body missions do not typically require an agile sail 20 - 22 July 201015Malcolm Macdonald
