For Phase A, two contractors built the proof-of-concept hardware. One contractor was chosen to build the TD hardware for Phase B. Both Phase A lesson learned and risk reduction activities at Ames Research Center were used to write the TD science objectives, scope, and requirements. The work at ARC aims to retire technical risks and provide design data to TCPS developers and the ISS system integrators. This paper will summarize the lessons learned from the proof-of-concept hardware and the risk reduction activities and how these lessons learned form the TD requirement matrix.application/pdfengTrash Compactor Processing SystemHeat Melt CompactorNextSTEPPresentations
