STATUS/ACCOMPLISHMENTS
The weekly systems team meeting addressed the SDO power budget study, 
dealing specifically with the solar array and battery sizing to address SDO 
operational and EOL power reqs.  This has been an ongoing investigation on 
meeting SDO EOL (end of life) requirements in light of potential hardware 
faults and mission requirements.  The SDO power team reviewed the options 
investigated over the last few weeks and the assembled team defined the 
next stages required in identifying the final implementation approach to be 
taken.  The HGA development team held an excellent review of the draft HGA 
development and qualification flow, further defining the issues at hand and 
helping to identify potential development approaches.  The GN&C team held 
their subsystem peer review, where they provided a detailed walk through 
and traceability of their complete GN&C requirements, as well as their 
subsystem implementation and development approach.  The Peer Review 
included independent GN&C discipline experts and RFAs were generated.  The 
Electrical systems team completed their work on the draft Electrical 
Systems Spec and submitted it to the SDO spacecraft team for initial 
internal team review.  The Radiation requirements specification, which 
further defines the SDO radiation environment throughout all phases of the 
SDO orbital mission, was also released to the SDO team after review and 
comment by the SDO systems team.  The GN&C team met with the SDO systems 
team and project to discuss their latest trade information on the SDO 
reaction wheel make/buy trade study and what steps should be taken next in 
order to make a final selection decision.  Finally, the systems team worked 
with the SPN and SDN development teams to help further define the 
implementation concepts and help define final design decisions and move the 
development process forward.  Progress continues to be made on the SDN 
Prototype with phase one of four phases of populating and testing 
completed.  Next week we will conduct our second internal project status 
review with each of our subsystems.  Our next Champion meeting, which our 
LWS program & HQs customers are invited to attend, will be 7/24 at GSFC.

The Instruments teams have started deliveries of their Phase A Concept 
Study Reports.  Plans/approvals are in place for GSFC/NRL/HMI to 
participate in the e2v CCDs and RAL camera electronics peer reviews on July 
16 & 17 in the UK.

The ground system team focused on completing the draft versions of the 
Detailed Mission requirements document and the OPS Concept Document which 
will receive a wider distribution for review.  The data distribution team 
received 18 responses to the mass storage RFI that closed on 6/26.  They 
are reviewing these responses as well as clearing the IN-SNEC (French) 
company through Code 100 for a product demo on 7/28 related to the 
RFI.  Also, the team completed their Command Security Risk Assessment for 
SDO which they will present to the project next week.

In the area of CM, the team: has been working to fix "bugs" in the intranet 
database; preparing the CCR for the Reliability Enhancement of HMI; 
collecting informal comments for the System Safety Program Plan and the SDO 
Electrical Systems Specification before formal review/CCR processing; 
coordinating comments from latest review for the Single Board Computer SOW 
and Specification; and supporting preparations for next week's internal 
project status review.

Thanks & have a Fun & Safe Holiday weekend,
Ken
