  3. Purpose of MCR NPR 7120.5D MCR Definition Per GSFC STD 1001B At the MCR, the project demonstrates to the review panel that the: • proposed mission meets the science objectives • proposed mission is feasible • proposed mission and operations design concepts are viable, • preliminary plan for development lifecycle activities suitably illustrates reasonable execution of the mission within resource budgets and other foreseen constraints • The MCR affirms the mission need and examines the proposed mission's objectives and the concept for meeting those objectives. • Key technologies are identified and assessed. • ROM budget and schedules are presented. NASA Procedural Requirement 7120.5D - NASA Space Flight Program and Project Management Req’s GSFC STD 1001B - Criteria for Flight Project Critical Milestone Reviews

  4. Required documents for MCR (from 7120.5D) • Draft Level 1 Requirements • Preliminary Formulation Authorization Document • Mission Concept Report (baselined at MDR) • Integrated Baseline - Draft • Baselined Work agreements for next phase • Preliminary Review Plan (per GSFC STD-1001B) Although not required, you should have the following documents: • Summary of trade studies already performed • Draft Mission Requirements Document • Draft Concept of Operations • Draft New Technology Development plan

  5. NPR 7123 requirements for MCR NASA Procedural Requirement 7123.1A - NASA Systems Engineering Processes and Requirements

  6. No Technology Performance Available/ Meets Risks Requirements Acceptable 12 11 Finalize Concept and Develop Report Peer Review PMRD – Refined and Validated Req’s ROM Costs Strawman Mission Concept 14 13 Study Guidelines: the study process Form Study Team and Develop Study Plan 1 Identify & Prioritize Key Design Parameters Strawman Develop Strawman End-to-End Mission Concept Mission Preliminary Top-Level System Needs and System Mission Concept(s) Objectives Requirements Req’ts Flow Down Develop Concept Evaluation Criteria Definition 2 8 4 6 7 5 Constraints& Iterate Requirements a nd Concepts Assumptions 3 No No System ROM Costs Cost/Performance/ Yes Yes Within Margins Guidelines vs. Requirements Evaluations 9 10 Yes Mission Concept Review 15

  7. Study Guidelines: study schedule should include these activities • Detailed mission concept definition • Sensitivity analyses (science measurement requirements and instrument performance parameters) • Cost estimates • Risk assessments • System impacts of new technology infusion • Concept validation • Mission trade space modeling • Study reports and archived models • Level 1 requirement definition • Temporal and spatial resolution requirements. • Measurement accuracy requirement as a function of spatial resolution. • Effect of orbit selection on mission performance. • Mission lifetime. • Other science requirements achievable by potential instrument combinations that could extend the mission applicability to other science questions. • Measurement(s) to be made • Science rationale (How measurements contribute to science question(s)) • Related measurements of complementary value • Define roles for international partners • Define a baseline instrument concept, including the rationale and key instrument performance parameters • Identify alternative instrument concepts • Define a spacecraft concept, including key spacecraft performance parameters • Identify launch requirements • Identify Supporting R&A investments • Identify Specific cal/val requirements • Generate a detail cost estimate for instrument, Ground System, MO& DA, Science, Project Management, Systems Engineering, and Flight Assurance. Parametric estimate for spacecraft. • Develop a detailed mission schedule (at least WBS Level 3 for instrument)

  8. Recent relevant MCR’s and their outcomes • SMAP: June 23, 2008 • HQ decision was delayed due to project costs over HQ budget. • ICESAT-II: February 10, 2009 • Delta MCR is planned • Earth Science Directorate and the Project did not have a clear agreement on mission objectives and requirements • Significant changes to the baseline are planned to be studied in Phase A • The estimated Life Cycle Cost (LCC) for the baseline mission exceeds the goal established by the ESD.

  9. Conclusion • Pre-Phase A is an iterative process. • Make it convergent • Explore the optimum range of cost, schedule, and capability that will maximize the science/cost ratio • Agreement on mission objectives & constraints is crucial • Define the best mission that fits within the allocated resources and is able to bring the mission to Phase A maturity. • Start preparing ~6 months prior to MCR 9
