STATUS/ACCOMPLISHMENTS
I thank the entire SDO team for supporting the GSFC Initial Confirmation 
Readiness Review.  The review went very well with commendations for our 
review chairs.  After the ICRR, we met with GSFC's Resource Analysis Office 
to follow-up on actions from the review.  The next step towards the 8/27 
ICR starts next week with the reconciliation of the IRT's Independent Cost 
Estimate.

The weekly systems team meeting covered the topic of Observatory grounding, 
with the focus on box-level grounding design guidelines.  In addition, the 
High Gain Antenna (HGA) team held a very successful peer review of the HGA 
system concept, design, and development flow concept.  Feedback from the 
peer review was very positive and provided excellent inputs in the further 
development of the HGA system and development approach.

The Propulsion team held an excellent meeting with the Project to complete 
the discussion of the various propulsion design options.  In addition, the 
Contamination team conducted a peer review which ensured that a Monomethyl 
Hydrazine (MMH) propulsion system meets SDO/Instrument contamination 
requirements.  The result of AETD's great work is that the Project concurs 
with Code 597's recommendation to use a MMH system for SDO.  The system 
includes a single 100 lbf main engine (MMH bi-prop) used to get to GEO 
orbit from GTO along with 8 MMH bi-prop 5 lbf thrusters used for ACS 
control & orbit raising redundancy.  This configuration closely resembles 
commercial GEO spacecraft and provides dual fault tolerance in achieving 
our GEO orbit.  The other good news is that this system is within or cost, 
schedule, & technical allocations.  GREAT JOB PROPULSION TEAM!

In the Instrument area, a few administrative items were worked this week 
including an interview with a Instrument Manager candidate and 
organizing/preparing CCRs for EVE contract modifications associated with 
the accelerated start of EVE's CCD efforts with MIT Lincoln Labs (Project 
controls/manages thru an Air Force tasking arrangement).  Also spent some 
time gathering up reference SOWs from a variety of GSFC projects which will 
be culled for relevant SOW content for Phase BCDE contracts with the SDO 
instruments.  On the technical front, a Project technical team visited the 
SHARPP instrument team at NRL to peer review the evolving SHARPP 
electronics design.  NRL has simplified the electronics configuration for 
both cost and spacecraft accommodation reasons.  Preparations continue for 
our next ICD session with the instrument teams.  The redlines and comments 
extracted from the visit to the HMI team two weeks ago has been worked and 
incorporated in the latest versions of our ICDs.  Detailed technical 
interface discussions are planned with the EVE team August 19 and 
20.  Similar discussions are planned with the SHARPP team in early to mid 
September.  We also have an ICD follow-up meeting with the HMI team planned 
in early September.

The Mission Assurance Team has been evaluating the mission assurance 
documentation supplied by NRL in support of the SHARPP instrument 
suite.  Documentation reviews were completed on their draft Performance 
Assurance Implementation Plan (PAIP), and Contamination Control Plan.  The 
draft PAIP's discrepancies against the SDO Mission Assurance Requirements 
(MAR) are being compiled and will be forwarded to NRL for 
discussion/action.  Reliability models for three different design 
configurations of the Propulsion System were developed using fault trees to 
compare reliability of the three configurations.

In the area of CM, the team is working on the final draft version of the CM 
Procedures and electronic CCR form (with instructions).  In addition, the 
team is reviewing and will be providing comments on EVE CM plan.

Thanks,
Ken
