Update on the Dependable Multiprocessor (DM7) ISS Flight Experiment

The NREP (NanoRacks External Platform), host for the DM-related flight experiments, was deployed on the ISS in 2016. The DM7 ISS flight experiment was launched to the ISS in December 2016 as part of the NREP Mission 2 sortie. The NREP Mission 1/Mission 2 switch-over took place in late April 2017, at which time the DM7 flight experiment was deployed and activated shortly thereafter. During the initial on-orbit checkout, all three DM7 experiment missions were successfully demonstrated. Per the NREP mission schedule, DM7 flight experiment is scheduled to last 6 months. The paper provides an overview of DM technology, an overview of the DM7 ISS flight experiment, focusing on the integration and operation of the DM ISS flight experiment within the space/ground infrastructure for NREP-hosted experiments, a summary of on-orbit experiment results, and lessons learned.
