NASA Applied Sciences: An Example from the Agricultural Efficiency Program Element Ed Sheffner Earth Science Division NASA Headquarters IGARSS Workshop July 30, 2006
Topics • Summary of current NASA organization and strategic plan. • Key elements in the approach of the Applied Sciences Program. • The NASA collaboration with FAS as an example of the approach.
NASA is a research and development agency formed in 1958 with responsibility for all US government, non-military aeronautic and space activities. Agency objectives (from 1958): – Expansion of knowledge of atmospheric phenomena; – Development and operation of vehicles carrying instruments in space; – Establishment of long range studies of the potential benefits accrued through the utilization of space for scientific purposes; – Assurance of US leadership in space science and technology and the application of that technology in peaceful activities “within and outside the atmosphere”; and, – Cooperation with other nations in the pursuit of peaceful application of NASA developed technology.
NASA Strategic Goals* 1. Fly the Shuttle as safely as possible until its retirement, not later than 2010. 2. Complete the International Space Station in a manner consistent with NASA’s international partner commitments and the need of human exploration. 3. Develop a balanced overall program of science, exploration, and aeronautics consistent with the redirection of the human spaceflight program to focus on exploration. 4. Bring a Crew Exploration Vehicle into service as soon as possible after Shuttle retirement. 5. Encourage the pursuit of appropriate partnerships with the emerging commercial space sector. 6. Establish a lunar return program having the maximum possible utility for later missions to Mars and other destinations. *NASA 2006 Strategic Plan
NASA Organization Four Mission Directorates – Aeronautics – Exploration Systems – Space Operations – Science (four divisions) • Earth Science – Flight/missions – Research – Applied Sciences • Heliophysics • Planetary Science • Astrophysics
Strategic Goal #3 A. Study Earth from space to advance scientific understanding and meet societal needs. B. Understand the Sun and its effects on Earth and the solar system. C. 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 space. Discover the origin, structure, evolution and destiny of the universe, and search for Earth-like planets. E. Advance knowledge in the fundamental disciplines of aeronautics, and develop technologies for safer aircraft and higher capacity airspace systems. F. Understand the effects of the space environment on human performance, and test new technologies and countermeasures for long duration space exploration.
Approach of the Applied Sciences Program • Draw upon NASA Earth Science capabilities: observations, measurements and predictive models. • Draw upon NASA Earth science research results. • Extend NASA capabilities and results to maximize the return-on-investment by addressing issues with substantial social and economic benefits.
Approach Elements of Applied Sciences Program (cont. ) • Select projects through open, competitive solicitations. • Use existing infrastructure for data archiving, distribution and product generation. • Define projects, and identify decision support tools, through partnerships with organizations with operational responsibilities.
Approach Elements of Applied Sciences Program (cont. ) • Program processes: – Solutions networks (identification) – Rapid prototyping (evaluation) – Integrated systems solutions (implementation)
Solutions Networks: Consider the results from NASA funded research in the six science focus areas of the Earth Science Division: - Atmospheric composition - Carbon cycle and ecosystems - Climate variability and change - Earth surface and interior - Water and energy cycle - Weather Identify potential improvements in the decision support tools within the portfolio of projects in the Applied Sciences Program.
Rapid Prototyping: Use specific research results in simulated operational environments to evaluate components and/or configurations for integrated systems solutions with the specific decision support tools within the portfolio of projects in the Applied Sciences Program.
Integrated System Solution: A rigorous systems engineering process that: • describes (evaluates) the state of a decision support tool/system, • verifies and validates new data products and other enhancements in the decision making process, and, • benchmarks the performance of the assimilation of NASA research results and capabilities in the decision making process.
What the Applied Sciences Program Prefers Not to Do • Develop new algorithms • Create new decision support tools • Long term support for infrastructure • Provide support for operational activities • Fund the research of other agencies The Program may participate in projects in which these activities occur, but those tasks will be supported by someone other than NASA, e. g. , the user/partner.

NASA Collaboration with FAS • Based on three projects selected through competitive solicitations: – Univ. of Maryland (Justice): Integration of MODIS land observation products – NASA/Goddard (Kempler): Integration of rainfall and soil moisture products – UMD/GSFC (Birkett): Reservoir height for water availability. • These products contribute to the “convergence of evidence” approach used by FAS to generate monthly production and yield estimates.
