(Fwd) [Fwd: SDO Weekly Report for June 25, 2004] Subject: 	SDO Weekly Report for June 25, 2004 Resent-Date: 	Fri, 25 Jun 2004 13:28:49 -0700 Resent-From: 	Philip Scherrer  Date: 	Fri, 25 Jun 2004 12:24:56 -0400 From: 	Elizabeth A. Citrin  SDO Weekly Report for June 25, 2004 The Project continues to have trouble pushing its GSFC procurements through the system.  Although it was reported at MSR that the RFI for the star trackers had been released, this report was premature.  This RFI has still not been released.  The Project had been planning to use the Code 500 Procurement Office for the four Attitude Control System (ACS) component procurements, but it is not clear now whether adequate personnel will be available to support this. An SDO Project Calendar will be available on the SDO MIS web site early next week.  The Calendar will provide information on the regular Project technical and programmatic meetings, on the Instrument and subsystem CDR peer reviews commencing in the fall.  Donyea Burroughs (Donyea.J.Burroughs.1--AT--gsfc.nasa.gov), our administrative assistant, will maintain the calendar. The Weekly systems team meeting addressed a draft list of major areas that need to be completed by and addressed at the Subsystem CDR presentations, both in order to reduce development risk and also to demonstrate that the subsystems and the project are at a level of design and implementation maturity adequate to warrant moving ahead into the flight phase of the project . The systems team has taken an initial first cut at this list all subsystems are performing a self assessment within their teams and their functional organizations on what items need to be added to demonstrate sufficient maturity to move on to flight article manufacturing. The ground system continued to test and verify the TSI Front End Processor at the GSFC test facility. The FEP did have to go back to the vendor last week for a Viterbi decoder problem but was re-received and testing has continued this week. The IN-SNEC FEP, the second type unit, is due for delivery in approximately two weeks. Also, the DDS group has ordered the remaining hardware to complete the fully functional DDS prototype system. Additionally, the GSM and Ground System Test Manager have entered into discussions with Dryden as to the capabilities of the NASA U2/ER2 aircraft and it's ability to support antenna verification. Finally, work on documents, databases, and system design continues. With the Phase A/B extension thru July, SDO, Lockheed Martin Solar Astrophysics Laboratory (LMSAL), and Smithsonian Astrophysical Observatory (SAO) continue working to complete the Phase C/D/E contractual effort. The Atmospheric Imaging Assembly (AIA) design and development progress continues with a baseline telescope assembly mount design, which will be forwarded to the Project for initial review, a draft mirror coating spec, and an RFP for the structural model telescope tube and flange pull test. Two lifetest filterwheels were received and the assembly of the prototype shutters has been started. The SAO and LMSAL thermal teams met and refined the models to support a power reduction effort and a July thermal peer review. The Helioseismic Magnetic Imager (HMI) team held a successful Critical Design Review for the Michelson Interferometers this week. GSFC participated in the Michelson CDR and no significant issues were identified in the review. The HMI ICD was baselined on June 21. HMI visited their structure subcontractor this week for a design status, and to conduct a working session covering design issues. HMI is currently conducting a trade study on DC/DC converters to evaluate impacts of switching converter manufacturers. The DC/DC converters are on the Common Buy list with SDO, and the HMI trade study is in response SDO re-evaluating their suppliers. At GSFC, the 2 mB SRAM proto-part were assembled on EUV Variability Experiment (EVE) Subsystem Data Node (SDN) Breadboard this week; the SDN team found a problem with the board and troubleshooting continues. Northrup Grumman is bringing on additional staff to overcome schedule delays in the development of C&DH Breadboards. Evaluation of the C&DH Single Board Computer (SBC) and High Gain Assembly Subsystem (HGA)S Gimbal Actuator proposals are on-going. RFI responses were received for the Ka-Band Solid State Power Amplifier (SSPA). -- Liz Citrin SDO Project Manager 301-286-1222 FAX 301-286-0214 Cell 410-241-0503 --  ----------------------------------------------------------------------- Message sent to the following people: Brock.A.Carpenter--AT--LMCo.com Darrel.Torgerson--AT--LMCo.com   akin--AT--lmsal.com  angelo.angelopoulos--AT--lmco.com augustus.s.moore--AT--lmco.com  barbara.fischer--AT--lmco.com bill.rosenberg--AT--lmco.com brad.watson--AT--lmco.com  carin.b.lundquist--AT--lmco.com carl.yanari--AT--lmco.com  carol.a.brosious--AT--lmco.com cathy.chou--AT--lmco.com cheryl.seeley--AT--lmco.com  chris.edwards--AT--lmco.com chuck.fischer--AT--lmco.com cliff.evans--AT--lmco.com  dale.wolfe--AT--lmco.com dave.chenette--AT--lmco.com dexter.duncan--AT--lmco.com  don.abadilla--AT--lmco.com donald.j.ausmus--AT--lmco.com  dwana.k.mcclurg--AT--lmco.com edgar.thomas--AT--lmco.com  edward.mcfeaters--AT--lmco.com elisabeth.l.barnett--AT--lmco.com  ericka.sleight--AT--lmco.com ernest.herrera--AT--lmco.com francis.lee--AT--lmco.com  friedlaender--AT--lmsal.com gary.f.heyman--AT--lmco.com  glenn.s.gradwohl--AT--lmco.com imai--AT--lmsal.com jennifer.l.chaban--AT--lmco.com  jerry.drake--AT--lmco.com jerry.janecka--AT--lmco.com jim--AT--shoom.stanford.edu  joan.c.dayog--AT--lmco.com john.r.vieira--AT--lmco.com john.w.miles--AT--lmco.com  jschou--AT--solar.stanford.edu karen.kao--AT--lmco.com keith.mitchell--AT--lmco.com  kent.zickuhr--AT--lmco.com larry.springer--AT--lmco.com lemen--AT--lmsal.com  levay--AT--lmsal.com louis.g.tavarez--AT--lmco.com mag--AT--aliasaerospace.com  mathur--AT--lmsal.com metcalf--AT--lmsal.com noah.katz--AT--lmco.com  pscherrer--AT--solar.stanford.edu rachel.richards--AT--lmco.com  rairden--AT--spasci.com ralph.p.seguin--AT--lmco.com ramona.o.jimenez--AT--lmco.com  rbush--AT--solar.stanford.edu rey.dayog--AT--lmco.com rick.rairden--AT--lmco.com  robert.j.blanchfield--AT--lmco.com roger.rehse--AT--lmco.com rogerc--AT--lmsal.com  ron.baraze--AT--lmco.com rose.d.navarro--AT--lmco.com ross.yamamoto--AT--lmco.com  russ.lindgren--AT--lmco.com ryan.moskal--AT--lmco.com sasha--AT--quake.stanford.edu  satyam.v.dave--AT--lmco.com sbmeyer--AT--lmsal.com schiff--AT--lmsal.com  scott.g.gibb--AT--lmco.com shine--AT--shimmer.lmsal.com shing--AT--lmsal.com  sokong.sour--AT--lmco.com susan.morrison--AT--lmco.com susan.piazza--AT--lmco.com  tarbell--AT--lmsal.com thomas.j.cruz--AT--lmco.com torgerson--AT--lmsal.com  viet.h.nguyen--AT--lmco.com virginia.whisnant--AT--lmco.com  william.c.taylor--AT--lmco.com wolfson--AT--lmsal.com zaki.m.kudiya--AT--lmco.com  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
