Subject: SDO Weekly Report for January 28, 2005 From: Philip Scherrer Date: Thu, 27 Jan 2005 22:22:54 -0800 To: hmi_local--AT--quake.Stanford.EDU -------- Original Message -------- Date: Thu, 27 Jan 2005 17:20:53 -0500 From: Elizabeth Citrin To: SDO WEEKLY DISTRIBUTION:; *_SDO Weekly Report for January 28, 2005 _* _Executive Summary: _ The HMI Science Team met at Stanford this week to discuss the software and data products needed for their science investigations. The anatomy of the data system and outlines of the major investigations were presented and details on data and software requirements, including how to generate the vector magnetic fields from the HMI measurements, were discussed. Several highly successful GSFC CDR peer reviews have been held recently, including the ACS, I&T, Propulsion and HGAS Gimbal Component. _Detailed Reports: _Version 1.1 of the SDO MIS was released this week, which incorporated most of the "bugs" which had been previously identified. This version also incorporates a "calendar" function that will be maintained as the SDO Project Calendar. _ _EVE is concentrating on preparations for the ICDR next week. ETU vibration, acoustic, EMI, and thermal testing have all been completed successfully. The ETU EEB testing has not progressed as expected with some issues in the interface to the SDO SDN . Debugging and analysis will continue. The final sections in the EVE ICD (to complete the baseline) have been reviewed, adjusted and ready for CCR approval. The EVE ICD will be ready for the ICDR; thanks to Chad Salo for his support. Stanford is holding an HMI science planning meeting this week with the HMI Co-Investigators on the implementation of the science pipeline. HMI is preparing the Structural Model (SM) for vibration testing at Wyle Laboratories in Los Angeles. The final components for the SM have arrived at LMSAL this week and assembly of the SM will be completed on Friday. The vibration test on the SM is scheduled to start Thursday, February 3, 2005. All parts and equipment for the ETU Filter Oven are in hand at LMSAL and the oven is in the final stages of assembly and instrumentation before the start of thermal vacuum testing scheduled to begin next week. The camera interface board is assembled and LMSAL has received the ETU DC/DC converters from SDO needed to complete the ETU power board. Flight FPGAs, LVDS drivers and receivers, and 1355 controllers have arrived at SDO and will be shipped to LMSAL next week as part of a common buy between the SDO project and HMI/AIA. Congratulations to Glen Gradwohl, HMI Mechanical Lead on HMI, and his wife Jennifer on the birth of their daughter Alyssa. AIA completed all twelve planned peer reviews leading to their February CDR. Inertial disturbance measurements were made this week at GSFC for prototype FilterWheel and Shutter mechanisms. Motors for the lifetest Aperture Selector mechanisms were received; all components for the remaining three mechanism life-tests are now in house and testing is scheduled to commence in several weeks. Fabrication of the SM entrance filters continues at Luxel; initial assembly of two Zr filters was completed. The SM set of filters will be delivered in early February. SAO has received the bonded tube assembly for the Structural Model and completed vibration testing of the SM Primary Mirror. Data analysis is ongoing as integration of the SM begins with testing planned in April at GSFC. Vacuum life testing of the Image Stabilization System active secondary mirror (PZT) has begun. The AIA monthly was held this week; LSMAL and GSFC continue to monitor critical path items. Spacecraft procurement activities continue to progress. Evaluation of proposals are on-going for the S-Band Transponder, Ka Band High Gain Antenna, and the Propulsion System Pyro Valves, Isolation Valves and Check Valves. With regard to our in-house avionics and development units, efforts continued. The final LPSC ETU was delivered by Northrup Grumman. The PSE ETU Battery Module and the Deployment Module are out for fabrication; the Solar Array Module is in checking. A meeting was held with the Logistics Management Division to discuss SDO shipping requirements and the transportation plan. A meeting was also held with Code 500 and Code 600 personnel to discuss the schedule for SDO moving in to the Bld 20 Highbay for harness fabrication. The Propulsion System and HGAS Gimbal Component CDRs were held this week. The ground system finished the Ground System CDR Agenda and has distributed it to both the Sr. Project System Engineer and the Code 300 CDR Board Chair/ team members for comment. The ground system team also help entered level-4 requirements into the DOORS system thereby linking the DMR and MRD requirements. This now links level 2, 3, and 4 requirements. The ground station Range Receive Command Processor (RRCP) purchase request has been officially released to the vendor, two to three weeks behind schedule but still in enough time to accommodate the antenna design process and ahead of the ordering of ground station antennas equipment. SDO E/PO staff re-introduced students at the St. John Vianney Catholic School to "The Sun" during a NASA sponsored in-school field trip for the First and Fifth grade students. In an effort to extend this experience, preparation for the students included several pre and post assessments and activities. During the actual visit, first grade classes were introduced to the structure and dynamics of the Sun, UV light and lessons on Sun Safety. The Fifth graders spent over 5 hours studying the dynamics of the Sun, conducting experiments using Ultra violet light and analyzing stars using their newly acquired knowledge of the light spectrum and "fingerprints" of specific gasses. Both groups were very excited to participate in interactive presentations about NASA, the space shuttle, astronaut training and what it is like to live and work in space. The teachers have decided to integrate many of the activities and information provided during this visit to enhance their science curriculum for next year. -------------------------------- Elizabeth Citrin SDO Project Manager NASA/GSFC 301-286-1222 (office) 410-241-0503 (cell) 301-286-0214 (fax)
