4. Role of the Earth Systematic Missions Program Office in Decadal Survey • All Decadal Survey Missions are directed missions and will be managed by the Earth Systematic Missions (ESM) Program office, housed at NASA Goddard Space Flight Center (GSFC). • This is former EOS Program Office renamed and re-envigorated for the Decadal Survey • Directed missions are managed by the implementing Center (LaRC for CLARREO) with oversight and assistance as needed or requested from ESM-PO • EMS-PO develops performance standards and provides independent assessments for all Decadal Survey missions • While housed at GSFC the ESM incorporates expertise from across NASA • In particular including science and instrument expertise from LaRC and JPL

5. NASA’s Project Lifecycle CLARREO is here Need to be here by October 2009

6. Road to KDP A: The Mission Study Process • Conduct studies and analyses to derive the Level 1 requirements (Science, engineering, cost and schedule) • Complete an analysis of alternatives resulting in a conceptual design, and conduct Mission Concept Review • Prepare for approval all documents required in NPR 7120.5D (NASA Space Flight Program and Project Management Requirements) 6

7. Study Guidelines: the study process Pre-Phase A is an iterative process. Crucial to conducting a successful study is agreement on a set of realistic mission objectives and their flowdown to science and measurement requirements that are documented in the mission’s Level 1 Requirements.

8. Study Goals & Objectives • Establish performance metrics, develop and document the mission science requirements (Level 1 requirements), explore the full range of implementation options, define an affordable project concept to meet requirements specified in the Level 1’s, identify needed technologies, and begin preliminary development of the Project Plan. • Define the best mission that fits within the allocated resources and bring the mission to Phase A maturity. Mission Study Teams should explore the optimum range of cost, schedule, and capability that will maximize the science/cost ratio across the entire Decadal Survey flight program.

9. Study Guidelines: activities • Investigate: • Potential Partnerships with non-NASA organizations • Instrument and mission design and development options, including make/buy decisions and alternative mission operations approaches • Conduct trades: • Science requirements, trying to identify the significant cost vs. performance parameters • Mission risk (looking for cost vs. reliability drivers) • Technology • Acquisition Strategy • Mission operations approach • Data Processing and distribution approach • Access to space (launch vehicle selection; co manifest; etc)

10. 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)

11. Roles & Responsibilities • Program Scientist (PS) – NASA HQ • Establishes a Science Definition Team and produces relevant documentation. • Assists the Program Executive (PE) in the establishment of a Technology Definition Team, if relevant. • Solicits scientific investigations and prepares the Announcemetnt of Opportunity supported by the PE and Project Scientist, with attention to how the mission relates to previous and subsequent planned missions. • Program Executive – NASA HQ • Tracks studies to define mission feasibility and desirability • Represents program interests on working groups to define missions and generate science plans • Establishes working groups to determine the advanced technologies necessary to enable future missions. • Maintains working relationships with NASA Center management, programs, and projects. • Provides liaison with SOMD’s launch-vehicle provider organization. • Acts as liaison between the study team and Office of External Affairs to initiate international agreements • Program Office – EMS-PO (GSFC) • Supports NASA HQ in conducting mission studies to develop mission concepts and determine feasibility. • Supports NASA HQ in new project start approval activities. • Develops launch vehicle requirements and launch windows identifying potential timeframes when launches can take place. • Develops project performance metrics. • Conducts trade studies to develop a viable project architecture that will be approved by SMD. This involves conducting technical/cost/schedule tradeoffs. • Ensures a Technology Plan is developed • Study Manager – Implementing Center (LaRC) • Establish the study office and structure to direct and monitor study tasks/activities • Initiate, support, and conduct concept studies consistent with direction and guidance from PS/PE-led working group • Originates mission requirements • Develop mission options, conduct trades, and develop cost estimates. • Assess technical, schedule, and cost performance and identify risk mitigation activities • Communicate study performance, issues and risks and present recovery plans • Conduct readiness reviews leading to KDPs

12. Program Office Support Available to Study and Science Teams • Mission design studies with GSFC’s Integrated Mission Design Center (IMDC) or JPL’s Team-X • Access to specific discipline engineering as needed • Operations and Ground System conceptual design with Earth Science Data Information System (ESDIS) and Earth Science Mission Operations (ESMO) Projects • Launch Vehicle coordination and access to space through Launch Services • Additional systems engineering support • Assistance with requirements analysis and derivation as needed • Independent Cost Estimate with GSFC Resources Analysis Office for consistency with other Decadal missions
