Citrin To: SDO Weekly Report for October 15, 2004 Executive Summary: The Spacecraft Project Monthlies were held this week. Subsystems continue to show progress towards their CDRs. The Project has been looking at options in the I&T schedule to accommodate later instrument deliveries. It appears that integrating the instruments to the Instrument Module (IM) after the IM is integrated to the spacecraft offers the most flexibility for these deliveries. AIA, EVE, and HMI also report good progress to their CDRs. Detailed Report: Samples from two potential vendors for the HMI front window were radiation tested at 200 megarads with gamma rays. Electron and proton radiation testing is scheduled for the front window samples before HMI makes the final vendor determination. The dry fit source inspection of the HMI Optics Package structural model was successful and Vision Composites has started bonding the model together. BAE has completed assembly of three flight processor cards and a source inspection is scheduled for next week. The parts for the alignment mechanism and front door have been received and assembly and test of these items will begin shortly. AIA team members participated in the SDO Electrical Grounding TIM held at GSFC this week. An internal Lockheed review of the AIA I&T environmental test flow was also held; a draft will be submitted to the Project next week. Fabrication of the structural tube for the Flange Bond Test Model was completed and flange bonding is expected to start shortly. The Primary Mirror flexures and support plate for the AIA Structural Model (SM) parts were received and SM filter wheels were ordered. Completion of the few remaining SM drawings is expected next week. The ground system is on schedule for finalizing the October decision on the antenna vendor selection. Best And Final Offer (BAFO) questions and final responses have been called for by 22 October. With that decision made, such questions as; antenna type, motor drive type, detailed electronic antenna specifications, costs, etc. can finally start getting answered. The new Mission Operations Manager (MOM) is fully on-board and coming up to speed. Associated with that, a new Mission Operations and Mission Support (MOMS) contractor organizational structure will be forth coming in an effort to deliver better response times to Project I&T efforts. The FDF Lead has started preparing launch and early orbit maneuver projections based on the Atlas-5 selection and is discussing coverage capability with the USN. Finally, all nominal development efforts in such things as operational scripts, software, purchases, document generation, and sub-system testing are proceeding on schedule. All flight motherboard Hypertronics (the cPCI Connector Manufacturer) connectors have been received but the Flight/Production Daughterboard units slipped due to plating problems. Hypertronics, Weiss-Aug, and SDO GSFC worked as a team investigating the plating anomaly. GSFC Materials Group provided the critical support for this investigation. The plating problem is linked to the base material being over-aged during the heat-treating process. Hypertronics and Weiss-Aug incorporated a back-up plan during this investigation. Connectors will start being delivered to GSFC starting 10/21/04. Weiss-Aug is addressing the heat treating process temperatures and performing -- Liz Citrin SDO Project Manager 301-286-1222 FAX 301-286-0214 Cell 410-241-0503
