to select the type and number of science instruments andthe deployment strategy in order to realize a low-costsolution that meets the expected science requirements.In addition to enabling a larger future network, smallerpenetrator platforms would lend themselves to besecondary payloads in order to demonstrate that thepenetrator platform is a reliable candidate for future,larger scale deployments. Lastly, the UK PenetratorConsortium provides an ideal model for approachingthe development and championing of these systems.By combining the resources of academic and industrypartners with the unique resources to realize these typesof missions, and providing continuity in the generationof concepts for future opportunities, the probability ofexecuting a successful mission is increased.ACKNOWLEDGMENTSThe authors would like to thank The Charles Stark DraperLaboratory, Inc. for its support in the development ofthis paper. In particular, we would like to thank SeamusTuohy in the Space Systems Program Office and JasjitHeckathorn in the Systems Engineering and EvaluationDirectorate. The authors would also like to thank ToddMosher of the Sierra Nevada Corporation for his inputsand comments.60 A Penetrator-Based Sensor Network for Planetary Geophysics
