NextSTEP GroundTest• PurposeofNextSTEP GroundTesting
– Evaluatedesignconceptsforhabitationsystems,throughtest• UsetesttosupportRACandDACanalysis
– MaturerequirementsforNextSTEP Phase3• NextSTEP isaPublic/PrivatePartnership
– Collaboratewithpartners,toensuredesignideasarefullyexplored– AllowNASAtomakethemostofthelimitedtimewehavefortest
• Identifyelementsofdesignthatimpactintegratedperformance– Packaging– Logistics– Consumables– Interfaces

Goal:PreparehabitatsystemsforsuccessfulGroundTestexecution
NextSTEP GroundTest• FocusforFY17
– EngageStakeholdersandSubjectMatterExperts• “BreaktheSilos”
– Developandpracticemethodologyfortest• IncludesmanagingRequirements,TestObjectives,ExecutionPlan
– Developandmaturecapabilityforintegrationandtest• GroundTestServices:Architecture,Simulation,Visualization• Environments:iPAS “FlatHab”andB9HabitatModules
