50th International Conference on Environmental Systems


The Spacecraft Air Monitor (SAM) is an advanced Ion Trap Mass Spectrometer being developed and fielded onboard the International Space Station as a Payload Technology Demonstrator. 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.
