10. AIAA TAC Agenda • Background • Goals/Scope • Summary of Past Events • Membership and Organization • Future Activities and Plans • Recommendation GSTC

11. AIAA TAC What is a Gossamer Spacecraft? Gossamer spacecraft are systems that have high deployed to packed volume ratios and are extremely low in mass. • Technical Focus: • Packing & deployment methods & effects • Rigidization methods & materials • Membrane technology • Highly integrated, multi-functional components • Mission concept development • Non-linear, large deflection analysis • Examples: • Antennas • Solar Sails • Solar Arrays • Telescopes • Habitats • Solar concentrators • Sunshades • ED&L Systems • Decoys • Rovers • Radiators • Space suits GSTC

12. AIAA TAC Why a Gossamer Spacecraft TC • Unique area that is rapidly growing in interest within the space community • No specific forum exists for Gossamer Spacecraft to promote: • Technology development • User education • Space community awareness • Cross-discipline interaction • Space systems effectiveness will increase through gossamer spacecraft advancement & application • Special forum to foster discussion on interrelated issues that are the heart of making a Gossamer system • The topic is emerging and is often shunned by various disciplines…needs its own forum to mature GSTC

13. AIAA TAC Committee Goals • To establish Gossamer Spacecraft expertise within the AIAA • Provide a technical resource for AIAA • Attract new members • To promote technical interchange between members of various disciplines within the space community • Provide a forum for communication between technology developers and mission planners • Provide leadership & direction to the community • Promote technical interchange with other AIAA TCs, AIAA members, & other professional organizations • Advance the understanding of Gossamer spacecraft within the space community • Sponsor conferences & sessions • Technical publications (papers/journals/books) • Student participation & activities • Workshops & Website presentations GSTC

14. AIAA TAC Communications Plan Communications are critical to meet our goals! • Request a liaison from other TCs attend one GSTC meeting per year and be include on “friends of GSTC list” (most will have opportunity at SDM Conf.) • Copy meeting minutes to other TCs and request feedback • Make presentations to other TCs at their meetings • Write Bi-annual interface summaries for inclusion with minutes • AIAA TCs the GSTC should interact with heavily: • Structures • Adaptive Structures • Materials • Space Systems • Aerodynamic Decelerators • Balloon Systems • LTA GSTC

15. AIAA TAC Proposed Scope of The Gossamer Spacecraft Technical Committee The purpose of Gossamer Spacecraft Technical Committee (GSTC) is to develop and promote the science and technology of analyzing, designing, manufacturing, and evaluating the materials and components that are unique to gossamer inflatable, deployable, and membrane Spacecraft. This will be accomplished by providing a forum for technical interchange, by providing leadership and a collective informed decision making body (which will include industry, academia, and government). The GSTC will also encourage the development and dissemination of technical information, promote technology awareness through outreach activities such as workshops and website development, assist in the development of industry standards, and foster technology awareness through relations with other TCs and professional organizations. GSTC

16. AIAA TAC Summary of Past Events • Industry workshops: • Space Inflatables Technology National Workshops • October, 1996 (150+ attendees) • May, 1998 (200+ attendees) • Gossamer Spacecraft Initiative Workshop, Oct 1999 (300+ attendees) • DoD Space Technology Alliance Workshops, 1999 (NRO) & 2000 (WPAFB) • Many system specific workshops (Solar Sails 1997, 2001 - Telescopes 1999, 2000, etc.) • Several Conferences have sponsored sessions specific to gossamer spacecraft • 39th & 40th AIAA SDM 1998/1999 — 2 sessions • 41st AIAA SDM 2000 — 5 sessions (Forum) • 42nd AIAA SDM 2001 — 8 sessions (Forum) • 43nd AIAA SDM 2002 — 9 sessions (Forum) • Several other conferences - 1 or 2 sessions GSTC
