Subject: SDO Weekly Report for December 3, 2004 From: "Elizabeth A. Citrin" Date: Thu, 02 Dec 2004 17:12:26 -0500 To: "SDO WEEKLY DISTRIBUTION":; SDO Weekly Report for December 3, 2004 Executive Summary: SDO is preparing a Configuration Change Request (CCR) to the SDO Level I Requirements, requesting an increase in the transfer orbit perigee altitude. The rationale for the change, which has been discussed with SDO’s Program Executive, is to increase SDO’s propellant margin over the mission life. KSC and International Launch Services are assessing the LV performance impacts and LV disposal implications of a perigee change. An assessment of any changes in the radiation environment will also be made. The Project continues to struggle with funding issues. Incremental allotments do not stretch very far given the number and size of the activities that SDO is funding. Detailed Reports: The upgraded SDO Management Information System was "rolled out" this week. The MIS serves as our document library and configuration management tool now has new functionality to handle drawings online and future expandability to cover Work Orders, PR's and PFRs. As with any new system there has been a few "growing pains" and minor adjustments will be made to the system in the coming weeks. Thanks to everyone for their patience and support of this effort. The EVE ICDR has been moved to the first week in February to accommodate instrument investigation into the engineering filter tear and CCD processing changes. SDO and Code 300 are able to support the new dates and the EVE team is checking their facility availability. The final three ICDR peer reviews for contamination, I&T and verification have been reset to December 15-16 to allow the team to focus on a number of tests on prototypes next week that require key personnel. In AIA news, COI has completed lay-up and trimming of the Structural Model (SM) composite structure and is fabricating fixtures for assembling the SM telescope. SM flanges have been shipped to COI for assembly beginning next week and the SM primary mirror was delivered by SORL to SAO to prepare for vibration testing in January. Kick-off meetings for fabrication of the flight primary and secondary mirrors were held and work on the first flight optic has begun. Lawrence Livermore National Laboratory delivered a report on lifetime stability of the Mo/Si coatings used in four AIA channels. The primary and secondary lenses for the HMI telescope have been completed and shipped to LMSAL. Progress continues on the assembly of the HMI Optics Package structural model and ETU filter oven. The HMI front window samples are being tested for low energy electron plasma radiation in response to an action assigned during the HMI CDR. The shutter life test will complete next week and is currently at 78 million of the planned 80 million exposures. The alignment mechanism assembly is nearing completion and will soon enter testing. The HMI power converter board is being fabricated, the Data Compression/High Rate Interface board has completed fabrication, the backplane board is in assembly, and the limb tracker board is in test. The ground system received the final MOC facility design from FMD this week, keeping the MOC facility development on schedule. All antenna vendors responding to the RFP have been notified and debriefs are being conducted. Associated with that, the first Range Receive Command Processor (RRCP) was selected for an initial buy and prototype testing, similar to what is being done with the Data Distribution System (DDS) Front End Processor (FEP) purchases. DDS has received its last hardware order and now has a functioning prototype system in place. Finally, most Pre-CDR Peer Reviews plans are being finalized across all ground system sub-systems. Security has been added as a 'subsystem' and will present to a separate peer-review panel. -- Liz Citrin SDO Project Manager 301-286-1222 FAX 301-286-0214 Cell 410-241-0503
