Multi-Mission Data Processing System Study, Phase 2: Design Review and Architecture Study

The Multi-Mission Data Processing System Study is being conducted to identify the best model for an open Mission Data Processing System (MDPS) to support upcoming NASA Earth science missions, particularly the coordinated missions comprising NASA's Earth System Observatory (ESO). The study will identify a data processing architecture that not only meets future mission science processing objectives and supports Earth system science, but also promotes open science principles and enables data system efficiencies.

The study comprises several phases, with each phase building on the results of the previous phase. In keeping with NASA open science guidelines and objectives, all phases in the study are open and encourage participation by the broader science and data processing communities. Phase 1: Concept Study was completed in March 2023.

Phase 2: Design Review and Architecture Study

Phase 1 of the Multi-Mission Data Processing System Study concluded with a recommendation for a MDPS designated Type 2 (Managed Services), Variant 4 (encompassing infrastructure, data, catalog, and analysis and processing services) and written as T2V4.

A detailed analysis of the recommended T2V4 MDPS began in March 2023 and a final report is scheduled for release in September 2024. This follow-on investigation will increase the fidelity of the architecture by establishing the use cases, system requirements, system definition, and potential impact to upcoming missions. Phase 2 will conclude with a final report and a data processing prototype with associated documentation.

Phase 2 is a detailed analysis of the recommended Type 2, Variant 4 (T2V4) Mission Data Processing System (MDPS). It will start with a systems engineering review followed by an analysis of extending the MDPS for multi-mission use and investigating candidate implementations and potential early adopters of the architecture.

A Formal Systems Engineering Review was held October 24-25, 2023, at NASA’s Langley Research Center in Hampton, Virginia.

The goals of the review were to:

  • Review systems engineering artifacts to validate architectural compliance and maturation of the Phase 1 T2V4 MDPS recommendation
  • Demonstrate ability to support ESO mission use cases as provided by ESO project representatives
  • Deliver prioritized development activities to enable an MMO-managed MDPS architecture to support ESO mission processing needs
  • Assess the maturity of the project and the progress made in defining the mission data processing system requirements to support ESO missions
