3Why 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
December

23Earth 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.
24Table 2.2.a Earth Science Mission Priorities and
Rationale
25Section 4.3.3 Planning for Future Missions
- Mission Profile w/ESSP every two years
- Medium Class Systematic missions every other year
starting 2017 (5 missions thru 2025) - ESSP mission every other year starting 2014 (6
thru 2025) - Mission Profile w/ESSP every four years
- Medium Class Systematic missions start 2016 (6
thru 2025) - ESSP missions every four years starting 2014 (3
thru 2025) - Mission Profile w/ESSP every four years includes
Large Mission - Large mission in 2021 (1 thru 2025)
- Medium Class mission starting 2016 (4 thru 2025)
- ESSP mission starting 2014 (3 thru 2025)

29NAC 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
comments - These comments were incorporated in Draft 3.75
- Most Science Subcommittees reviewed how we
addressed their comments in their September
meetings - Findings addressed in letters to the NAC SC
- The NAC Chairman identified two issues with draft
3.0 - 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
science - Draft 4.0 articulates next steps in lunar science
planning in each Science chapter. Chapter 8 is
substantially revised in this direction
30ESS COMMENTS ON DRAFT SCIENCE PLAN
- 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
InSAR) - Flesh out Earth Science objectives beyond 2016
- Observation/prediction of rapid environmental
change - new technologies for Earth observation
(microsatellites) - 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
31National Research Council Overview
- Supportive of NASAs approach to mission
prioritization - 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
32NRC 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,
schedule) - 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
33NRC 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
missions - explicitly address realistic strategies for
achieving the objectives of the mission-enabling
elements - 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
34NRC 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
completed. - 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
prediction. - 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
observations.
35Impacts of the NPOESS Nunn-McCurdy Certification
- Presidential Decision Directive/NSTC-2 of May 5,
1994 created the National Polar-orbiting
Operational Environmental Satellite System
(NPOESS) - 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
2005 - The restructured program was certified on June 5,
2006 - 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
36NPOESS Nunn-McCurdy Certification Content
Reductions
37Summary 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
ALT - 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
completed - NASA/Navy/NOAA continuing discussions for joint
future altimetry mission
38Next 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

42Coordinating 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
policy - 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
managers
43NAC 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
- Dr. Mark Robinson - Arizona St. Univ.
- Dr. Lennard Fisk - NRC Space Studies Board
chair (ex officio)
44NAC Science Committee Subcommittees
S-06-5
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
45SMD Participation in the Vision for Space
Exploration
- SMD has the lead for the robotic Mars, solar
system, and planet finding components of the
Vision - 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
46NSAG 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
direction
47NSAG 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
48Ocean 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
(2008) - NOAA and Navy are planning future operational
missions - 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
49Interim Report Recommendations
- Proceed with the GPM and the Atmospheric
Soundings from Geostationary Orbit (GIFTS)
missions - Evaluate plans for transferring needed
capabilities to NPOESS (Ocean Vector Winds, LDCM,
GLORY) - Develop a technology base for future Earth
observation - Reinvigorate the NASA Earth Explorer Missions
Program - Strengthen research and analysis programs and
- Strengthen baseline climate observations and
climate data records.
