If you're interested in the details, these are HS-2 Critical Design Review documents I did myself or was a major contributor to:
Software design · Mission design · Mission operations · Ground support design · Ground data system · CDH block diagram
Interface Control Documents (ICD): Payload · Ground · Communications · Command and data handling
Command and telemetry list · Technical Budgets (Excel). For my work, see the Data Downlink/Storage Budget, Data Uplink Budget, Storage over time, and Processor/Bus Utilization Budget tabs.
