7. 2003 2004 2005 Charter Activities GSPC Meetings & Annual Reports Website Enhancements Report to TAC Organize GSF Conference 2004 or 2005? Identify Liaisons Publish Trends & Issues Summaries Outreach Activities 3 Year Plan In process

8. Industry Trends & Issues • Identified subcommittee support members • General plan • Identify & create metrics (draft in progress) • Create questionnaire for Scientists & Mission Planners • Create Trends (roadmaps) charts • Target officials/groups who can help or use the information to advance Gossamer • Bullitize major trends and needs for growth • Disseminate and communicate

9. Metrics (T&I) • - Metrics (top level information planners will use): • $ Spent on Gossamer vs Year • TRL vs Technology (rigidization, deployment mechanisms, analysis tools, etc.) • TRL vs Component Type (antennas, solar sails, sunshields, etc.) • Timeline of gossamer spacecraft flights (spheres...IAE...Hughes 702...solar sails...etc.) • Packed Volume vs Deployed Volume Examples? • We should try to create metrics that highlight gossamer advantages and provide useful general information that might affect funding and usage • Match metrics to roadmaps (need $$$ to do this!) • Any thoughts regarding data sources, better metrics, usefulness of the metrics to the community?

10. Questionnaire • Focus - "What would it take to get you to fly a gossamer component/spacecraft?" • We should ask scientists, planners, or systems people this question (through a series of questions) to identify weaknesses to be addressed • Get first hand input on the impediments they have in using this technology and help steer technology developers • We need to make a simple, yet thoughtful questionnaire, that won't take much time to fill-out • We publish the results on our website, and disseminate to community (& policy makers) Brainstorm a list of recipients Generate questions

11. Industry Trends • We need to identify the general needs for growth...to enable missions • Example - We want 100m apertures to find planets...here is what is needed • Some of this is in NASA/USAF/ESA planning documentation, some in SBIR solicitations, NRA solicitations, etc. • Maybe we can get some general information from Chris Moore, others, etc., that would help • Gather existing focused roadmaps into one source on website Brainstorm trend areas

12. Gossamer Industry Report Card Addressed by steering actions

13. Steering Subcommittee Plan • Formed Subcommittee 4/15/03 • Identify Metrics 11/15/03 • Generate Questionnaire 1/15/04 • Send Q & Receive/chart input 3/15/04 • First Draft Trends 1/15/04 • Finalize 2003 T&I for SDM 3/15/04 • Disseminate & Monitor 4/01/04 • Via Communications Subcommittee

14. Action Items • Need input from each Subcommittee • Need to locate on web • This will be updated after this meeting Sample

15. GSPC Project Discussion • Lassiter Slides • Standards question (Lou) • Back-up information • Lassiter e-mail suggestions... • 1. Database (on our web site or some other) of gossamer spacecraft technology providers (who does design, analysis, testing, mission planning, etc.) • 2. Materials database for gossamer structures (proprietary issues I know will come up) • 3. Review of NASA, DoD, NRO, etc programs wrt use of gossamer spacecraft. Develop white papers to show deficiencies in funding, planning, R and D needs, etc. and recommend certain courses of actions.

16. Standards From: Michael Lou [mailto:michael.c.lou@jpl.nasa.gov]Sent: Tuesday, July 29, 2003 5:28 PMTo: Lassiter, JohnSubject: RE: Questions for Proposed Technical Standard "Design Methodology for Space Inflatable/Rigidizable StructuresJohn,The more important question is: Do we really need a standard (government or non-government) for gossamer structures at this time. My answer to this question is: Probably not - At least not before we have cumulated enough experience from a couple of gossamer flight systems. that actually fly.In light of the above, I think the GSPC can immediately start with the development of a gossamer structures design guidelines document and use this as a vehicle to collect the thoughts and experience from its membership. After such a guidelines document is written, reviewed, and published, we should let it be used by the practicing engineers for a few years and then turn it into (i.e., reduce it to) a government or non-government standard.Mike

17. Scope • Advocacy Group for the Research, Development & Applications of Gossamer Spacecraft • Mission Concepts Studies • Consider all Components of the System Through the Spacecraft Lifecycle • Educational Support • Political Advocacy • International Forum What are we doing to support our scope?

18. Purpose • Promote the Development and Use of Gossamer Spacecraft Technology • Foster understanding in policy makers, systems designers, scientists, and technologists • Encourage improvements in Gossamer technologies via technical interchange • Be an advocate for technical excellence What are we doing to support our Purpose?

19. Activities • Sponsoring or co-sponsoring conference sessions, forums, short courses, student competitions, workshops, and other conferences • Advocate policy to AIAA on gossamer spacecraft topics of national interest, and participate in AIAA advocacy events such as Congressional Visits Day • Facilitate the review and publishing of gossamer spacecraft articles • Encourage technical interchange among companies, government agencies, and universities to advance gossamer spacecraft technology, standards, and systems integration • Establish liaisons with TC’s and technical societies with related interests • Honor technical contributors through awards, nominations for AIAA Fellow, and recommendations for member upgrades • Ensure an active membership that is representative of the gossamer spacecraft community • Conduct educational and public policy outreach activities to further promote interest in gossamer spacecraft technologies

20. Adjourn Thanks you for your dedication, participation, and perseverance!
