STATUS/ACCOMPLISHMENTS
We received the Independent Review Team's cost estimate and we are working 
reconciliation.  The IRT plans to rerun their model early next week in 
support of the 8/21 GSFC PMC ICE review.

The GN&C team presented the results of their Reaction Wheel Trade study to 
a panel of independent experts.  It was agreed by all that the study 
provided sufficient information to provide a basis for the SDO Project to 
make a decision on whether to make or buy the reaction wheel assembly. The 
results of the study will be presented to the SDO Project early next 
week.  The Single Board Computer procurement package was sent on to legal 
for their concurrence before release.  The procurement will provide SDO 
with breadboard, ETU and Flight units, as well as breadboard units for 
GPM.  An option can be exercised by GPM to procure their required number of 
ETU and Flight units.  Progress continues to be made in preparing the test 
setup for Atmel 1355 radiation testing, scheduled for the Labor day weekend.

For the Instruments, preparations continue for next week's interface 
requirements meeting with the EVE instrument team.  Updated ICDs were 
generated and released.  The CCD process masks were produced at e2v and the 
first production run employing the thin gate process was 
started.  Conversations to refine the CCD readout electronics requirements 
continued with RAL (camera electronics).  RAL released their flight 
production schedule which is tight but supports the HMI and SHARPP need dates.

The ground system has been preparing for the System Requirements Review 
(SRR), scheduled for September 17, 2003.  The Mission Operations Concept 
Document is nearing completion and the Detailed Mission Requirements will 
soon be ready for Project review.  Per GSFC invitation, INSNEC provided the 
team with three full days of testing/evaluation of their viterbi decoder 
(possible part of SDO Data Dist. Sys.) product.  The demo was well received 
and INSNEC's product was able to handle our data volume.  The viterbi 
decoder was one of the ground systems risk areas and it now appears there 
is a commercial solution.  Many of the ground system engineers are at White 
Sands finalizing the MOU between the Ground system and WSC.  The engineers 
will be discussing infrastructure requirements and antenna locations.

In the area of mission assurance, the team has been evaluating the (PAIP) 
assurance documentation supplied by the Laboratory for Atmospheric and 
Space Physics (LASP) in support of the EVE instrument.  Documentation 
reviews were completed on their draft Performance Assurance Implementation 
Plan (PAIP) and the differences against the SDO Mission Assurance 
Requirements (MAR) are being compiled and will be forwarded to LASP.  The 
Software QE supported the SDN Bootstrap/Monitor Loader flight software code 
walk-through on August 15.

The CM team started the process of installing ProE on their computers in 
support of handling mechanical drawings.  In addition the team, coordinated 
comments received from reviews of various documents & they are in the 
process of wrapping up comments on SDO-CCR-015 (Release of System Safety 
Program Plan), SDO-CCR-017 (Release of Data Capture Budget), and 
SDO-CCR-018 (Release of Structural Analysis and Test Requirements 
Document).  SDO-CCR-016 (HMI Reliability Enhancement CCR) received CCB 
approval on 8/12/03.  Following this approval, the following documents were 
updated and released: SOW for SDO HMI Phase A (Revision A), SDO Project 
Mass Budget (Revision B), and SDO Project Power Budget (Revision A).  We 
also opened SDO-CCR-019 (Accelerated Start of MIT LL CCD Development Phase 
for EVE Detectors) and distributed the SDO Project Plan to the LWS SET 
Project for reference.

Thanks,
Ken
