SDO Weekly Report for May 21, 2004

Last Friday, the SDO Project, together with the LWS Program and the 
IIRT,  provided a pre-brief to Code S of the LWS/SDO EPMC presentation that 
is scheduled for May 26, 2004.   The Mission Confirmation Briefing to the 
Agency PMC is still scheduled to place on June 2nd.

SDN Breadboards continue to be built up; some boards are being completed 
with existing 512kB SRAM parts to work around the delay experienced in 
receiving 2 mB SRAM parts. The delay was caused by a software problem the 
vender (3D PLUS) was having. 3D PLUS reports the problem has been resolved 
and the current plan is to ship the SRAM parts on 6/15/04.  Layout effort 
continued for the GCE GIC and GCE ASD, SPN PCC and LPSC, ACE RWI, and C&DH 
Ka Com, S Com ASD, BMC, Overlay and PSE ASD Breadboards. A task through the 
MSES contract was exercised for provision of the Gimbal Actuator and ECRA . 
The SSPA Breadboard #2 was in assembly.  A number of ACS, Propulsion and Ka 
Band Specs and SOWS were completed and scheduled to be baselined via a SDO 
CCB meeting next week.

The ACS subsystem and Spacecraft simulator requirements were baselined in 
the SDO project CCB meeting.

Members of the AIA and HMI instrument teams from Lockheed Martin and 
Stanford attended an Interface Working Group (IFWG) meeting at GSFC with 
significant progress being made towards the projected baseline release 
of  instrument ICDs. Systems implementation and design topics that were 
addressed included SDO High Speed Bus Design, Spacecraft time 
keeping/distribution, pointing and alignment requirements, Guide Telescope 
interfaces, mechanical interfaces, contamination and  I&T.  In parallel, 
the first monthly programmatic review of HMI and AIA was held. The PDR 
level AIA reduced thermal model was delivered to the SDO project. HMI has 
submitted responses to the Mission PDR RFAs.

This week the ground system team visited the last vendor site of the three 
companies responding to the Antenna RFI. Six hours of detailed technical 
information was exchanged between SDO GS and vendor engineers. This purpose 
of these visits is to ensure proper RFP responses on the first release of 
the Antenna RFP in June.

The audit of SDO's controlled property, conducted by the Property 
Management Branch and a member of the Project Support Team, was 
successfully completed with a 100% score.

We would like to welcome our newest member of the Project Support Team, 
Donyea Burroughs. Donyea will be replacing Terry Hynson, as Terri is moving 
to the NPP Project next week.

Regards,

Rob Lilly
