Decadal Survey Mission Planning

Presentation to CLARREO Workshop

Steve Volz

October 21, 2008

  • Decadal Survey Missions
  • Overall Decadal Survey study objectives
  • Mission Development Approach

NASA Late-Term Missions (6/15 total)

*Cloud-independent, high temporal resolution, lower accuracy SST to complement, not replace, global

operational high-accuracy SST measurement

nrc decadal survey recommendations
NRC Decadal Survey Recommendations
  • NRC made 29 different recommendations in many areas for Earth Science
  • NASA is working to address the many recommendations
  • Within the Flight group we are addressing only a few of them
    • DS missions
    • Venture class development
    • TSIS & CERES recovery
    • Completion of current portfolio
  • Other ESD groups are addressing
    • Technology development (ESTO)
    • R&A issues
    • Applications science

smap icesat ii
  • SMAP and ICESat II are the first two Decadal Survey (DS) missions the ESD and NASA will implement.
    • SMAP project is being conducted out of JPL, and completed its transition to Formulation in September 2008. The projected / planning launch date is now early 2013.
    • ICESat II project is being conducted out of GSFC, and is working to its Mission Confirmation Review in early 2009. The launch date is under study, expected between 2014 and 2016
    • Both missions (and all DS named missions) are directed science missions with individual budget lines. They are managed out of the Earth Systematic Missions (ESM) Program Office located at GSFC.
clarreo desdyni
  • CLARREO & DESDynI are the next Decadal Survey missions to be addressed by the ESD
    • Both missions are directed science missions with individual budget lines. They are managed out of the Earth Systematic Missions (ESM) Program Office located at GSFC
  • The CLARREO mission is led by LaRC, with GSFC support
    • Draft level 1 requirements & initial international partnership discussions, Fall 2008
    • Initial mission concepts, Spring 2009,
    • Full technology readiness assessment, MCR October 2009
  • The DESDynI is led by JPL, with a significant GSFC contribution
    • Draft level 1 requirements & initial international partnership discussions, Fall 2008
    • Mission configuration down select, Spring 2009
    • Full technology readiness assessment, MCR October 2009
what about the venture class
What about the Venture Class?
  • NRC Decadal Survey recommended a “Venture Class” line of small, cost- and schedule-constrained, competitively selected “missions” to complement the identified strategic missions
    • Higher risk posture allowed, Class C missions, single string instruments allowed
    • High risk, high return demonstration technology a consideration
    • Creative spacecraft & launch options considered
  • FY09 budget does allow a “Mission of Opportunity” with start in FY10 and launch NET FY14 -- with only a small amount of money
  • The named missions in the Decadal Survey will not be Venture Class, but will be executed through the Earth Systematic Missions Program Office
    • Class B or Class C missions
    • NASA certified launch vehicles
    • 3+ year mission life, with commensurate reliability requirements
    • High TRL for instruments required at confirmation

Where do we expect to be by October 1, 2009?
  • For each of the Near- and Mid-Term missions in the Decadal Survey:
    • Quantitative assessment of the readiness to proceed to Formulation (Phase A)
      • Draft level 1 science requirements, baseline mission concept, draft formulation authorization document, partnership evaluations, technology readiness level assessments
      • Mission Confirmation Review (MCR) readiness expected for CLARREO and DESDynI based on FY09 budget, but to be determined by teams’ demonstrated progress
    • Mission maturation plan for FY10 and beyond, through launch and ops
      • Life Cycle Cost, independent cost and schedule estimates
  • Decadal Survey Program assessment, including:
    • Cross cutting mission analyses, constellation measurement requirements, ground systems, platform, and ground networks
  • Definition of scope and implementation approach for the Venture Class of small mission opportunities

esd execution of decadal survey missions
ESD Execution of Decadal Survey Missions
  • All Decadal Survey Missions concepts studies are directed by the ESD and will be managed by the Earth Systematic Missions (ESM) Program Office at GSFC
  • All mission development will have a study management team, led from HQ ESD by the HQ Program Scientist and Program Executive, and including representatives from ESTO, data systems, applied sciences, and the ESM program office
  • All members of the mission study ESD teams should be involved in all relevant study discussions, and the PS and PE are expected to participate in cross mission science and mission trades
nasa hierarchy of directives
NASA Hierarchy of Directives
  • NPR 7120.5D - NASA Space Flight Program and Project Management Requirements governs the processes associated with formulating and implementing a new flight project
  • Important details for GEO-CAPE:
    • Defines the Major Milestones
    • Identifies all requirements for each phase of the Project
    • Identifies all gate products for each phase
    • Defines roles and responsibilities
    • Identifies all major reviews

  • Support the assessment of Technical Readiness Levels
  • Identify potential partnerships
key pre phase a questions
Key Pre-Phase A Questions
  • What science MUST this mission achieve?
    • What specific measurements?
    • To what accuracy?
    • What are the required data products?
  • What mission parameters can achieve the science?
    • What orbit (inclination/altitude)?
    • Which instruments?
    • What is the baseline mission duration?
  • How can NASA achieve these measurements?
    • Are there other missions required/desired to achieve the science?
    • Who can NASA partner with to achieve this mission?

Should be resolved ~ 12 months prior to KDP A
