The eventual goal of such Payload Technology Demonstrators is to prove system capabilities for human spaceflight, with a particular goal toward future development and implementation for deep space exploration. This paper will cover the initial fielding of SAM Technology Demonstration Unit 1 (TDU-1) on board the International Space Station, the initial checkout of the system, and the associated data gathering from this period.application/pdfengMass SpectrometerAtmosphere MonitoringInternational Space StationSpacecraft Atmosphere Monitor Technology Demonstration Unit 1 Initial Performance On Board the International Space StationPresentation
