NextSTEP GroundTest• PurposeofNextSTEP GroundTesting

– Evaluatedesignconceptsforhabitationsystems,throughtest• UsetesttosupportRACandDACanalysis

– MaturerequirementsforNextSTEP Phase3• NextSTEP isaPublic/PrivatePartnership

– Collaboratewithpartners,toensuredesignideasarefullyexplored– AllowNASAtomakethemostofthelimitedtimewehavefortest

• Identifyelementsofdesignthatimpactintegratedperformance– Packaging– Logistics– Consumables– Interfaces
