SDO Weekly Report for April 16, 2004

The SDO Project Management team is continuing to focus on the next steps in 
the Confirmation Review process.   The Project debrief with the IRT took 
place and there were no surprises from SDO's standpoint.  We continued to 
work with RAO this week as they put finishing touches on the independent 
cost estimate.

Members of the SDO project and technical staff visited Northrop-Grumman's 
Lanham facility where a number of key Printed Circuit Boards (PCBs) for 
in-house avionics boxes will be assembled.  The meeting gave the Project a 
chance familiarize N-G management with SDO, our schedules/priorities as 
well as discus design, layout and manufacturing issues.  The Project will 
visit OSC, the other main supplier of in-house PCBs next week. On the 
procurement front, comments on the Single Board Computer draft RFP were 
received. The final RFP should be released by the end of the month.

The SDO systems engineering team reviewed the Mission PDR RFAs, assigning 
them to the appropriate project subsystems and distributed them to the 
team.  A telecon with KSC was held to discuss the SDO/Launch Vehicle 
Interface Requirements Document.  KSC would like to release a draft RFP for 
SDO Launch Services by the end of the month.  The C&DH team conducted a 
pre-layout review of the Ka-Comm. breadboard.

The AIA PDR took place this week at LMSAL.   Congratulations to the entire 
AIA team. It was very evident that a tremendous amount of work has been 
completed in the 5 months since AIA was added to the SDO Project.  Very 
good feedback was received from the Code 300 review team.  On another 
positive note,  LMSAL presented an improved instrument delivery date of 
12/2006.

Regarding the HMI contract, Stanford has received all materials and cost 
estimates and will be submitting a proposal for an AIA and HMI Common Buy 
of CCDs, CEBs, and EEE parts within the next few days.  In addition, HMI 
expects the contract for the HMI Optics Package structure with Vision 
Composites to be in place by next week. The life test shutters for HMI are 
currently in thermal test. A CDR for the critical filter in HMI, the 
Michelson Interferometer, has been scheduled for mid June 2004. A detailed 
radiation analysis of HMI is underway with results expected in June 2004.

In the Ground System area, the GS PDR package was completed and distributed 
to the Code 300 Chair and Board members this week. The Ground System PDR is 
scheduled for 21-22 April.

The SDO Configuration Control Board baselined the Detailed Mission 
Requirements (DMR) document this week.
