42. Earth Science and Applications from Space Strategic Roadmap DRAFT, 4/18/2005 AM42Strategic Roadmap Committee #9 Interim Status Report Educating and Inspiring Future Generations Earth science and applications from space continues to excite, inform, and educate the general public and enhance our daily lives. NASA Earth science research offers unique opportunity to engage, inform, and educate the scientists and technologists of tomorrow through missions with direct human relevance, both to life on Earth as well as to our human need to explore and discover. By revealing the secrets of how the Earth system works in exciting and innovative ways, NASA can ignite a spark that stimulates students to pursue these endeavors by becoming scientists and engineers. Earth science education community is meeting to define an education roadmap for the next decade, and will also provide input for the 30 yr timeframe of this roadmap. –Earth Science education roadmap highlights the importance of engaging and inspiring the public, partnering with agencies that also contribute to this effort, building on this inspiration to educate students and support educators in their efforts to prepare students for the career paths needed. The results of the on-going Earth Science Education Roadmap effort, combined with that from the Earth Science and Applications from Space Strategic Roadmap Committee, will be incorporated into the Education Strategic Roadmap, which is only now getting underway.

45. Earth Science and Applications from Space Strategic Roadmap DRAFT, 4/18/2005 AM45Strategic Roadmap Committee #9 Interim Status Report Disclaimer for June 1 Report The Committee and staff anticipate that the final report developed as a result of its next meeting will identify notional mission priorities and anticipated accomplishments by decade. The implementation concepts for the measurements identified in this roadmap range in fidelity from carefully studied options to initial notional approaches. The pace and schedule for the development of this strategic roadmap did not allow for the extensive systems analysis to refine and validate the implementation reflected in the document. This initial strategic roadmap document represents a recommended conceptual framework for the future of Earth science and applications from space, but will require on-going analysis and validation over the coming years. This strategic roadmap includes currently funded NASA investigations and their planned accomplishments for information purposes only –NASA asked the Committee to assume that NASA will complete currently funded missions in the first decade of the Roadmap, including: missions in implementation that NASA has committed to complete missions in formulation that have yet to pass their Mission Confirmation Review assuming that NASA will find a flight opportunity for the Glory instrumentation –The Committee did not prioritize or make recommendations concerning currently funded activities

59. Earth Science and Applications from Space Strategic Roadmap DRAFT, 4/18/2005 AM59Strategic Roadmap Committee #9 Interim Status Report Possible Nanotechnology Capabilities Proposed Connections from the Capability Roadmap Team CapabilityRequirementDate Required Investment Start ROM Cost Rationale for Capability 1. Ultra-high strength, lighter, and multi- functional materials (100x stronger than steel), i.e., large lightweight antenna There probably is no requirement on improved materials, however, based on current Earth Science and Applications from Space concepts studying the myriad of phenomena and dynamic characteristics of Earth from space, lightweight, high strength, and multi-functional materials will enhance mission success while also saving on overall costs of missions due to less mass, longer durability, etc. 20102005?Lightweight, high strength, and multi-functional materials will enhance mission success while also saving on overall costs of missions due to less mass, longer durability, etc. 2. High efficiency power generation and storage High efficiency power generation and storage would greatly enhance any space based mission by requiring less mass and fewer complex “power capture” systems that could potentially be “single point failure nodes” 20122005Long term power needs on long missions in Near- Earth orbit are drivers for cost and in some cases, determine durations of missions. Advancing technologies within the nanotechnology world have promising solutions on several fronts with high efficiency power generation and storage capabilities 3. High miniaturized spacecraft systems and instruments; Micro-electronics 100x smaller and less power consuming Robotics, instrument systems High miniaturized spacecraft systems, instruments (including lasers), smaller, radiation tolerant and less power consuming electronics would mean less mass and less power required to meet mission goals 20102005Less mass miniaturized spacecraft systems and less power consuming electronics are nicely coupled to make missions more affordable and realistic for achieving the science goals. Nanotechnology is at the forefront of developing these technologies to facilitate and make possible these strategic features for all future missions

60. Earth Science and Applications from Space Strategic Roadmap DRAFT, 4/18/2005 AM60Strategic Roadmap Committee #9 Interim Status Report Possible Advanced Telescopes & Observatories Capabilities Proposed Connections from the Capability Roadmap Team CapabilityRequirementDate Required Investment Start ROM Cost Rationale for Capability 1. 2-5 m deployable collectors Collection areas sufficient to enable high- sensitivity active and passive optical measurements from low- to high-Earth orbit. Areal cost <$1K/m2, areal density <0.5 kg/m2. Missions: EASI, WS LIDAR. 20202005?Current meter-class collectors offer insufficient scope for mounting missions subject to low photon efficiency beyond LEO. Some concepts require large “photon buckets” even at LEO. 2. Meter-class deformable aberration compensated mirrors Coherent active optical measurements require closed-loop dynamic wavefront correction in order to optimize system response. Missions: HResCO2. 20172005?Optimization of system photon efficiency reduces requirement on collection area and/or source power. 3. 50-m deformable deployable RF reflectors. Coherent active radiofrequency measurements require closed-loop dynamic wavefront correction in order to optimize system response. Missions: LEO/MEO/GEO InSAR, GSM. 20152005?Optimization of system photon efficiency reduces requirement on collection area and/or source power. 4. Wavefront sensing and control algorithms with 1/20-wave resolution. Coherent active optical measurements require closed-loop dynamic wavefront correction in order to optimize system response. Missions: HResCO2. 20172005?Optimization of system photon efficiency reduces requirement on collection area and/or source power. 5. Precise, repeatable deployable support structures. Precision static, deployable, or assembled structures are required to enable all >4 m implementations. Missions: EASI, WS LIDAR, LEO/MEO/GEO InSAR. 20152005?High stability precision positioning is a key enabling capability that overcomes size, packaging, and space environment issues enabling operation of advanced telescopes and observatories identified in the NASA strategic plan. 6. Test and validation techniques for large area reflectors. Ground verification of on-orbit performance is desirable for mission assurance purposes. Missions: GSM, LEO/MEO/GEO InSAR. 20102005?Future large space optical and radiofrequency reflectors will not be ground testable and will thus require investment in new modeling and validation approaches.
