GSPC Steering SubcommitteeResponsibilities:

Update the GSPC Three-Year Plan annually.

Review annually the industry trends, uses, needs, and issues and develop an actionagenda for committee consideration.

Suggest, review, and make modifications to the charter (all major changes must bevoted upon by the GSPC membership and passed with a 2/3 majority).

GSPCMetrics (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

GSPCQuestionnaire

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

GSPCIndustry 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

GSPC Action Items

Need input from each Subcommittee Need to locate on web This will be updated after this meeting

ID # ASSIGNED TO ACTION STATUS DATE DUE OPEN / CLOSED

1 Cadogan Get in contact with AIAA directly for info on how to become a TC.

E-mail sent to Emily Springer at AIAA. Have information - distributed.

6/15/2001 C

2 Cadogan Contact Jenkins for history and contacts in AIAA on becoming a TC.

Not required. Info from Emily. 6/15/2001 C

3 Cadogan / Lassiter Rework charter and put it out for review. Cadogan completed it on 7/5/01. 6/22/2001 C4 Cadogan Mail AI list to Lassiter, ABC and CJ for review. Complete 6/1/2001 C5 Cadogan / Lassiter Develop actions for Jake Lewis at Ball to help

withWill offer secretary roll. Need to contact him to ask.

6/22/2001 C

6 Cadogan / Lassiter / Jenkins / ABC

Develop concepts for surveys -- Users need and acceptance -- TRL and technologies/path for dev't -- Experiments that need to be done -- Possible flight opportunities -- (make surveys specific to type of system (sail/antenna, etc.) )

Tabled topic - decided to go with less controversial "needs statements".

7/15/2001 C

7 Cadogan / Lassiter Determine how to get data to people who can use it, and in what form (managers/planners get TRL info, designers get tech info, etc.)

Evaluate JPL Gossamer Web page. Will use the website and communications with TCs. Also, AIAA articles.

7/15/2001 C

8 Cadogan Talk to ABC about funding this work. Waiting ABC response - will need funding to support TC presentation to AIAA if possible. ABC no longer has access to funding for this.

6/22/2001 C

9 Cadogan / Lassiter Develop GSWG objectives list that doesn't overlap with other TC's.

In charter and presentation to TAC. 7/1/2001 C

10 Cadogan Get a copy of AIAA by-laws for TC's and structure GSWG TC's.

On AIAA Website 7/1/2001 C

11 Lester / Slater ID conferences that GSPC TC might be interested in and create a page on the website.

This is something for the website (Joe should create a page). Cadogan has input for review.

5/15/2003 O

12 Cadogan (all) ID venue for meetings over next two years (possibly space symposium).

Fall 2002 meeting will be at ILC (need a date). SDM spring 03 in Norfolk. Fall 03 is TBD.

5/15/2003 O

13 Slater Get GSPC website launched. Need ABC input. Cadogan needs a printed copy or access to review if possible. Joe created www.gossamer-spacecraft.com.

GSPCGSPC 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.

GSPCStandards

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 Structures

John,

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.
