  • Near-term planning for plan amendment

Why a New Science Plan?
  • NASA released a new 2006 NASA Strategic Plan in
    February 2006, in keeping with the triennial
    requirement in the Government Performance and
    Results Act
  • The Science organizations follow with a strategic
    document describing their implementation of the
    NASA Strategic Plan
  • The Space and Earth Science Enterprises produced
    strategy documents in 2003 it is timely now for
    the Science Mission Directorate to produce its
    first strategy document
  • The Congress requires NASA to produce such a plan
    in the 2005 NASA Authorization Act signed last

NASAs Strategic Goals
  • Strategic Goal 1 Fly the Shuttle as safely as
    possible until its retirement, not later than
  • Strategic Goal 2 Complete the International
    Space Station in a manner consistent with NASAs
    international partner commitments and the needs
    of human exploration.
  • Strategic Goal 3 Develop a balanced overall
    program of science exploration, and aeronautics
    consistent with the redirection of the human
    spaceflight program to focus on exploration.
  • Strategic Goal 4 Bring a new Crew Exploration
    Vehicle into service as soon as possible after
    Shuttle retirement.
  • Strategic Goal 5 Encourage the pursuit of
    appropriate partnerships with the emerging
    commercial space sector.
  • Strategic Goal 6 Establish a lunar return
    program having the maximum possible utility for
    later missions to Mars and other destinations.
  • 2006 NASA Strategic Plan

NASAs Strategic Goals
  • Strategic Sub-goal 3A Study Earth from space to
    advance scientific understanding and meet
    societal needs.
  • Strategic Sub-goal 3B Understand the Sun and
    its effects on Earth and the solar system.
  • Strategic Sub-goal 3C Advance scientific
    knowledge of the origin and history of the solar
    system, the potential for life elsewhere, and the
    hazards and resources present as humans explore
  • Strategic Sub-goal 3D Discover the origin,
    structure, evolution, and destiny of the
    universe, and search for Earth-like planets.
  • Strategic Sub-goal 3E Advance knowledge in the
    fundamental disciplines of aeronautics, and
    develop technologies for safer aircraft and
    higher capacity airspace systems.
  • Strategic Sub-goal 3F Understand the effects of
    the space environment on human performance, and
    test new technologies and countermeasures for
    long-duration human space exploration.

Earth Science Mission Priorities and Rationale
Highest priority is given to missions that
fulfill Legislative or Executive Branch mandates
and inter-agency commitments. Systematic
mission priorities are based on the importance of
the measurement to global change research and the
maturity of the operational transition
plan. These are followed by missions that will
make first-time global measurements two
pathfinder missions having been selected within
the same competitive process have a relative
priority inferred by the launch order. The
representative future measurements are not listed
in priority order. The forth-coming first NRC
decadal survey for Earth science will identify
science community priorities for future
measurements, as well as begin to address issues
arising from recent changes in the NPOESS
program. Also influencing the eventual priorities
is the US Integrated Earth Observation Strategy,
which plans the US contribution to the Global
Earth Observation System of Systems.

NAC Subcommittee Plan Review
  • The NAC Science Committee discussed the draft
    Science Plan outline and approach in May and the
    draft (3.0) in July
  • (see next slide on the NACs recommendation and
    NASAs response)
  • The Science Subcommittees reviewed the draft
    (3.0) in their July meeting(s) and provided
  • These comments were incorporated in Draft 3.75
  • Most Science Subcommittees reviewed how we
    addressed their comments in their September
  • Findings addressed in letters to the NAC SC
  • The NAC Chairman identified two issues with draft
  • In his view, the draft was not well written.
  • NASA plans two rounds of professional editing
    before completion
  • The draft did not adequately address lunar
  • Draft 4.0 articulates next steps in lunar science
    planning in each Science chapter. Chapter 8 is
    substantially revised in this direction

  • Adopt scenario of medium mission/2yrs, ESSP/4yrs
  • First open mission in current plan is an ESSP
    in 2014 examine trade-off of scheduling medium
    mission instead
  • Atmospheric composition continuous( gair
    quality) global ( gclimate) measurement should be
    top priority, implies sentinel orbit (L1 or GEO).
  • Better discuss cross-cutting opportunities in
    instruments platforms across focus areas,
    importance of complementary technology (example
  • Flesh out Earth Science objectives beyond 2016
  • Observation/prediction of rapid environmental
  • new technologies for Earth observation
  • Earth system modeling
  • Better articulate science purpose of suborbital
    program, esp. UAVs
  • Legacy road maps move to Appendix. New road
    maps in 2007 (after decadal survey input)
  • Overall document needs executive summary
  • Acronym list at beginning of each chapter

National Research Council Overview
  • Supportive of NASAs approach to mission
  • the committee does not believe that NASA should
    or could produce a prioritized list across
    disciplines at this time.
  • Concerned with NASAs ability to carry out the
    plan given the budget
  • Extensive reference to the NRC report An
    Assessment of Balance in NASAs Science Program
    SSB view of FY07 budget request
  • Recommendations are cast in terms of
    recommendations on the implementation and
    viability of the draft Science Plan
  • Several are not comments on the Plan per se, but
    on actions SMD should take e.g., on RA and
    controlling mission cost growth
  • Several good comments that will improve the
    document. These are now in work by the Science
    Plan team for incorporation in draft 4.0

NRC Findings
  • The draft NASA Science Plan successfully
    demonstrates that a major NASA objective is
    conducting scientific researchPortions of the
    plan do an excellent job of outlining the reasons
    that NASA carries out science missions
  • The committee supports the plans treatment of
    priorities on a discipline-by-discipline basis
    and concludes that NASA should not or could not
    produce a prioritized list across disciplines
  • the current draft overemphasizes
    mission-specific work at the expense of
    strategies and steps for achieving goals in
    mission-enabling areas
  • The draft Science Plan often declares an
    intention to implement a program or identifies a
    goal or mission as a top priority, but it does
    not indicate what steps it would take to achieve
    the goals (issue of mission cost growth, risk,
  • lacks a strategy for an integrated synthesis of
    the variety and volume of Earth observations
    generated by NASAEarth system modelslinking and
    cross-cutting the six ES interdisciplinary
    science focus areas

NRC Recommendations
  • compare the key aspects of its 2003 Earth and
    space science plans with the 2006 plan in a list
    or table
  • provide some indication of the strategy it will
    use to determine how critically needed
    technologies will be developed for future
  • explicitly address realistic strategies for
    achieving the objectives of the mission-enabling
  • Undertake appropriate studies through its
    advisory structure in order to develop a
    strategic approach to all of its RA programs
  • Develop a strategic plan to address computing
    and modeling needs, including data and
    information stewardship
  • NASA should improve mechanisms for managing and
    controlling cost growthundertake independent,
    systematic, and comprehensive evaluations of the
    cost-to-complete of each of its space and Earth
    science missions
  • NASA/SMD should move immediately to correct the
    problems caused by reductions in the base of RA
    programs, small missions, and initial technology

NRC Recommendations for Earth Science Plan
  • NASA/SMD should incorporate into its Science Plan
    the recommendations of the NRC Earth science
    decadal survey interim report, and should
    incorporate the recommendations of the Earth
    science decadal survey final report when it is
  • NASA/SMD should develop a science strategy for
    obtaining long-term, continuous, stable
    observations of the Earth system that are
    distinct from observations to meet requirements
    by NOAA in support of numerical weather
  • NASA/SMD should present an explicit strategy,
    based on objective science criteria for Earth
    science observations, for balancing the
    complementary objectives of (i) new sensors for
    technological innovation, (ii) new observations
    for emerging science needs, and (iii) long-term
    sustainable science-grade environmental

Impacts of the NPOESS Nunn-McCurdy Certification
  • Presidential Decision Directive/NSTC-2 of May 5,
    1994 created the National Polar-orbiting
    Operational Environmental Satellite System
  • In 1999 NASA and the NPOESS Integrated Program
    Office (IPO) agreed on the NPOESS Preparatory
    Project (NPP) as an alternative to the second
    round of Earth Observing System (EOS) mission
  • Due to a variety of technical problems, the
    completion cost for NPOESS grew by more then 25
    initiating the Nunn-McCurdy process in December
  • The restructured program was certified on June 5,
  • Restructured NPOESS deletes much of the climate
    research observing capability
  • Office of Science and Technology Policy (OSTP)
    asked for a white paper on the subject on June
    25, 2006

NPOESS Nunn-McCurdy Certification Content
Summary of N-M Reductions and Actions
  • De-manifested Sensors OMPS Limb Subsystem, TSIS,
    ERBS, Ocean Altimeter (ALT) and APS.
  • Reduced Coverage Sensors VIIRS and CrIS
  • Reduced Capability Sensor Conical Scanning
    Microwave Imager (CMIS)
  • Navy tasked with providing mitigation plan for
  • NASA developed white paper now in review with
    NOAA for joint paper submission
  • OSTP request for costs and schedules to restore
    the original capabilities preliminary costing
  • NASA/Navy/NOAA continuing discussions for joint
    future altimetry mission

Next Steps
  • Accommodate Science Plan reviews (including other
    agencies and White House Offices) to generate
    Version for NASA final approval and submit to
    Congress Dec. 2006
  • Release of the Decadal Survey (DS) by the NRC to
    NASA (and other sponsoring agencies) late 2006
  • Assessment evaluation of NPOESS N-M impact by
    WH and NRC panel report
  • Develop Earth Science roadmap following DS
    priorities and mission studies results
  • Develop amendment for the Earth Science plan and
    submit to Congress mid-2007

Coordinating External Advice
  • The standing advisory committees chartered to
    give advice to the Agency are
  • NASA Advisory Council (NAC)
  • Aerospace Safety Advisory Panel (ASAP)
  • ISS Independent Safety Task Force
  • The NAC is the primary external group advising
    NASA on its implementation of national space
  • All other (formerly) independent groups and
    committees have been brought under the purview of
    the NAC
  • In this way, advice to NASA is coordinated and
    provided to the Administrator
  • The NRC performs studies at the request of the
    Congress or NASA, but is not part of the standing
    advisory process
  • Responsibility and accountability for planning
    and executing NASAs programs resides with NASA

NAC Science Committee Members
  • Dr. Edward David Chair - NAS/NAE, EDD Inc.
  • Dr. Owen Garriott - Skylab Spacelab astronaut
  • Dr. Alan Stern - SWRI NH-Pluto PI
  • Dr. Neil DeGrasse Tyson - AMNH- NY
  • Dr. Bradley Jolliff - Washington U/St. Louis

    chair (ex officio)

NAC Science Committee Subcommittees
SMD agrees and has prepared a first external
review draft of the Science Plan based on the
President's FY 2007 budget for NASA. Initial
review of the NAC Science Subcommittees was
generally positive. The entire NAC will receive a
revised draft for review at its October meeting.
Note NASA cannot use OMB budget guidelines
in a document to be publicly released before the
budget is approved. The FY 2008 budget will be
presented in February 2007.
  • Develop the Science Plan draft using the
  • following guidelines
  • Define key scientific questions for each area
  • Define reasonable progress in each area by 2016
  • Describe the roles of major project elements
    (RA, technology, large and small missions, etc)
    in each area. It is understood that the means
    will differ from question to question
  • Use OMB budget guidelines as the financial
    envelop to
  • - Define missions and specific programs
  • - Define ST investments that need to be
    made now to enable a robust set of
    program/mission options in 2011
  • - Use this planning exercise to inform FY08
    budget formulation

SMD Participation in the Vision for Space
  • SMD has the lead for the robotic Mars, solar
    system, and planet finding components of the
  • SMD is working with ESMD on planning for science
    that enables and is enabled by the human
    exploration portion Vision
  • SMD is sponsoring an NRC study of Lunar science
    priorities interim report delivered, final to be
    delivered in May 2007
  • SMD and ESMD are jointly supporting the NASA
    Advisory Councils Lunar Science Workshop planned
    for Feb 26-March 2, 2007
  • SMD is funding the Moon Mineralogy Mapper mission
    on Indias Chandrayaan-1 mission
  • EMSD is funding a radiation environment
    instrument on SMDs Mars Science Laboratory
  • SMD is funding an open solicitation for Lunar
    sortie science concepts for the early human lunar
    missions proposals due Oct. 27
  • The Discovery and New Frontiers Programs both
    currently provide opportunities for the science
    community to propose missions to accomplish lunar
    science investigations
  • SMD plays a program scientist role in LPRP
  • Lunar Reconnaissance Orbiter (LRO) data sets will
    be archived in the PDS and available to the
    community starting 6 months after the end of
    prime mission.
  • As funds can be identified, SMD plans to initiate
    a Lunar Data Analysis Program

NSAG Consensus Views
  • General Reactions
  • a very good document
  • answers the mail in responding to Congress
    with considerable justification for the approach
    the Agency is taking
  • can be improvedincreasing use of graphics,
    adding greater description of societal benefits,
    and a more comprehensive discussions of the
    interactions between SMD and ESMD plans, esp.
    lunar science
  • Clearly a difficult task to develop an Earth
    science plan absent an NRC decadal survey some
    detailed comments in Consolidated Comments
  • Responsiveness to Congressional Direction
  • addresses the Congressional direction in spirit
    while not necessarily to the letter
  • the NSAG supports SMDs approach of presenting
    its prioritization by disciplines
  • creation of a single chart, showing all
    divisions missions togetherthrough 2016
  • NASAs Prioritization Rationale
  • generally appear to be internally
    self-consistent and consonant with Congressional

NSAG Consensus Views (contd)
  • Technology Development and Insertion
  • does not focus much attention on the technology
    development needed
  • The Earth Science Technology Office (ESTO) and
    the New Millennium Program could be described in
    greater detail
  • Industry possesses a wealth of applicable
    technology, and NASA should address this resource
    and how it can be tapped in this plan
  • Mission Size Mix
  • better define what is meant by large or
    small missions
  • The plan shows a decrease in launch rate of AO
    missionsthere is a consensus that this class of
    mission is very valuableit is not our intent to
    make a specific recommendation in this regard
  • Industry-NASA Relations
  • provide a clear statement of the value of the
    industry-government partnership
  • Greater collaboration with industry is
    recommended in order to get industry inputs and
    analyses early on in the process of
    conceptualizing architectures, missions, and
    relevant technologies

Ocean Altimeter (ALT)
  • Oceans exert great influence on climate huge
    sink for solar energy
  • Transport heat in ocean currents, release it back
    into the atmosphere as water vapor, transport it
    in the atmosphere, condenses, and returns as rain
    or snow the hydrologic cycle
  • Satellites offer a synoptic view of oceans
    starting with Seasat (1978), Geosat (1985),
    TOPEX/Poseidon (1992), JASON-1 (2001), and OSTM
  • NOAA and Navy are planning future operational
  • NASA is working with the Navy and NOAA on an
    advanced altimetry mission that is backward
    compatible with OSTM and includes a Ka-Band
    interferometer ocean altimeter to provide wide
    swath coverage and greater spatial resolution
  • This approach enables the examination of land
    surface water (rivers and lakes) as well as
    costal waters that are not presently available
    with OSTM
