Susan Elrod:

We are in the process of transitioning to the new Sharepoint site: https://info.aiaa.org/tac/SMG/STTC/Minutes/Forms/AllItems.aspx

The previous site content has been transferred but needs to be updated. http://www.aiaa.org/portal/index.cfm?adview=12&tcspageid=1650&getcomm=92

We particularly need updates to the: MembersSTTC CharterSubcommitteesOfficersStudent Design Competition TC Member Highlights Calendarand others

Please look at other TC websites for desirable content and possible format updates, and provide input back to Carl and Susan (susan.elrod@nasa.gov).

No inputs to date,

No action!!

Student CompetitionChuck Larson/Brian Bjelde ---

• Status and Actions: The 2008-2009 competition has been completed.The 2009-2010 competition (Human Asteroid Exploration System) is

currently in work and we should receive Student team letters of intent in April of 2010 (AIAA promised these soon). Need to begin planning for the receipt of proposals in June followed by a 1mo period of judging. There were some lessons learned from the judging of the 2008-2009 SDC so we will try to revisit these and incorporate process changes into the 2009-2010 and future judging activities.

The STTC 2010-2011 SDC abstract was submitted and approved by AIAA. Draft RFP in work and looking for volunteers - due to AIAA by mid-May.

Thanks to all those who participated. We will write up an abstract and send it out for a quick review before sending it to AIAA.

Abstract for 2010-2011 CompetitionTitle: Propellant Depot Design and Analysis of Economic Benefit Level: Undergraduate Abstract:Space has become ubiquitous, touching all aspects of human life from communications to agriculture, weather forecasting, disaster relief, travel, science and humanities excitement of exploring the unknown. The high cost of space access and limits of existing launch vehicles dampen the growth of space to further influence our lives. It has been suggested that the advent of propellant depots will reduce the cost of space access by fostering a large commercial launch market while also severing the direct link of on-orbit mission capability to launch vehicle performance. This design competition asks teams to develop a space transportation architecture centered around propellant depots.

The transportation architecture should be designed for an initial operation capability in 2020 with a 10 year operations lifetime. Submissions should address:

- What space markets (human exploration, interplanetary probes, communication, Earth sensing, security, commercial tourism, etc.) will benefit from the proposed transportation architecture and why.

- What is the potential market for on-orbit supplied propellant. - Discuss initial deployment of fuel depot and how the business case can close.- Details of the proposed propellant depot design such as propellant choice (hydrazine, RP1, LO2, LH2, etc.), depot

orbital location(s), depot overall design and how specific technical challenges (rendezvous and docking, propellant handling and transfer, cryogenic propellant (if included) boil-off accommodation, and depot maintenance) are overcome, and protection from orbital debris .

- What new system development is required to support the proposed transportation architecture (new launch vehicles, orbital transfer stages, etc).

- Programmatic challenges/benefits of proposed architecture (required funding and funding sources, increased launch rate and launch competition, risk of multiple rendezvous events, depot usage by other parties)

Student Competition Schedule2009-2010 Student competition “Human Asteroid Exploration System”

1.       Draft RFP sent around STTC for evaluation May 29, 20092.       Final RFP sent to AIAA, June 3, 20093. RFPs publicly released ~Aug 20094.       Students Letters of Intent due ~Mar 2010 (AIAA is collating the 2009-2010 SDC information now and should be

able to give us info about number of teams and schools early next week.)5.       Students proposals due to AIAA by ~Jun 2010 6.       STTC evaluation of proposals (typically 3-6 weeks in Jun/Jul 2010) I want to do this better than we have in the

past! There is a lot to review and we want to make the judging as fair as possible. Let's plan to have a SDC call on this in June after we see how many proposals we have.

7.       STTC final selection/approval of 1st, 2nd, 3rd place teams typically at Joint Propulsion Conference (usually ~Jul 2010)8.       SSTC informs AIAA to support the award announcement (in ~Aug 2010)9.       Winning teams announced and recognized by AIAA at Space (usually ~late Aug/early Sep 2010)

2010-2011 Student competition “Design and analysis of economic benefit of a Propellant Depot” <- AIAA accepted our Competition title

1. STTC abstract due to AIAA on Dec 2009 2. STTC RFP due to AIAA by May/Jun 2010 (Draft completed. Looking for volunteers to help polish this and

contribute....Bernard has already volunteered-Thx!)3. RFPs publicly released ~Aug 20104.       Students Letters of Intent due ~Mar 20115.       Students proposals due to AIAA by ~Jun 20116.       STTC evaluation of proposals (typically 3-6 weeks in Jun/Jul 2011)7.       STTC final selection/approval of 1st, 2nd, 3rd place teams typically at Joint Propulsion Conference (usually ~Jul 2011)8.       SSTC informs AIAA to support the award announcement (in ~Aug 2011)9.       Winning teams announced and recognized by AIAA at Space (usually ~late Aug/early Sep 2011)

And, finally –

A couple of thoughts >>

A minister decided that a visual demonstration wouldadd emphasis to his Sunday sermon.

At the conclusion of the sermon, the Minister reported the following results:

The fourth worm was put into a container of good clean soil.

The third worm was put into a container of chocolate syrup.

The second worm was put into a container of cigarette smoke.

The first worm was put into a container of alcohol.

DEAD DEADDEAD ALIVE!

Maxine was sitting in the back, quickly raised her hand and said,

"As long as you drink, smoke and eat chocolate, you won't have worms!"

Four worms were placed into four separate jars.

So the Minister asked the congregation - What can you learn from this demonstration?
