Upper Stage Engine (USE) Test Stand A-3 Preparing for New Test Series:
The A-3 test site has seen a great deal of activity during thepast week at Stennis Space Center (SSC). Figure 1 shows thepre-fabricated steel components that will be assembled into thetower arriving at the site on Monday, November 3. Figure 2 shows 16 truckloads of steel being delivered and staged forinstallation which began on October 29. The tower isscheduled for completion in April 2009.
Figure 1
During the arrival of the tower steel, sheet piling was beingdriven for the Liquid Oxygen (LOX) barge dock, as shownin Figure 3 . Both the LOX and Liquid Hydrogen (LH 2)waterways have been partially dug and rock has been laid.The docks and waterways are also scheduled for completion
in April 2009.

Subscale diffuser testing is continuing at the E-complex. The
current test series is generating data to mitigate risk associatedwith nozzle delta-pressures during facility transients.

machining and fit-up work was performed at the Michoud Assembly Facility (MAF). The composite
laminate skins were manufactured in Marshall Space Flight Center (MSFC) Building 4707.
Recent activities specific to the Elements include:
• Flight and Integrated Test Office (FITO) and Ares I-X
o Ares I-X Roll Control System (RoCS) Element: Activities specific to the RoCS Elementinclude:
Flight propellant tanks were installed onto module A and B structures, and electricalharnesses were installed on both modules.
The final X-ray Non-Destructive Evaluation (NDE) was run on the flight tank vent valveweld caps. One non-conformance was noted and it is to be decided at the MaterialReview Board (MRB) to either disposition as-is or swap out the tank with the spare.
A helium tube weld defect occurred on the first flight set of pressurant tubes, notablyafter the cold flow unit helium tube set was successfully welded. An investigation isunderway to look at inert gas regulation. Meanwhile, flight propellant tubes are beingwelded with no issues thus far.
The RoCS Installation Drawing update was released through the Teledyne release desk. RoCS supported the Integrated Readiness Review at Kennedy Space Center (KSC) last
week.
• First Stage (FS)
o FS Avionics Design Technical Interchange Meeting (TIM): The FS avionics LineReplacement Unit (LRU) subcontractor, L3-Cincinnati Electronics, held their first majorLRU design review at their plant in Cincinnati, OH, on October 21–24. CincinnatiElectronics is a subcontractor to the FS prime contractor ATK. Representatives from theAres I FS and Upper Stage (US) elements along with ground operations and vehicleintegration participated in the design review with ATK. A follow-on TIM with CincinnatiElectronics was conducted in Huntsville, AL, on October 27–28, with the representativesfrom various NASA and ATK pyrotechnics and thrust vector controlcommunities. Comments to the design review will be worked over the next month as
Cincinnati Electronics proceeds with their LRU designs.

• Project Integration (PI)
o Ares Outreach Activities : The Ares Projects outreach team supported the LouisianaAerospace Industry Day in New Orleans, LA, on October 15. Approximately 150 peoplelearned more about ways that small businesses can get involved with the prime contractors onfuture Constellation Program contracts in the New Orleans area. The outreach team presentedthe Constellation and Ares stories to 25 visually-impaired students from the TennesseeSchool for the Blind, who visited MSFC on October 21. Students also visited the MSFCPropulsion Research and Development Laboratory and center test stands to learn aboutMarshall’s Ares work. Team members also prepared and coordinated presentations on AresProjects development, Ares I vehicle integration and testing, and Ares V at the AmericanAstronautical Society’s Von Braun Memorial Symposium on October 21–22 in Huntsville,AL.
The Ares Projects look forward to the completion of the J-2X Critical Design Review (CDR) Pre-Boardwhich is currently underway and the J-2X CDR Board on November 13.
…and as of this Ares Projects Weekly Summary, there are only 253 days until the first Ares I test flight, Ares I-X!!!
