STATUS/ACCOMPLISHMENTS
This week, SDO's Project Management staff spent two days conducting our 
monthly Project Status Review (cost, schedule, technical) with each SDO 
subsystem lead.  Element to element schedule links and budget verses actual 
cost were reviewed, in preparation for the SDO AETD Champion Team meeting 
set for July 24. The Project also had two meetings with the GSFC Resource 
Analysis Office to provide additional information needed for their 
independent cost estimate.

The systems team is in the final stages of incorporating and reviewing 
updates to the SDO Mission Requirements Document (MRD), which is planned 
for distribution next week to the SDO team for review and comment. Final 
review of the SDO data capture budget is being completed prior to 
submission to the configuration change board for baseline CM. Subsystems 
teams are in the process of submitting initial responses to the SDO SRR/SCR 
RFAs in preparation for the upcoming ICR meetings next month. The systems 
team is continuing to work with the power group in updating the power 
budget, solar array sizing and spacecraft power requirements. In addition, 
the systems team has been updating the allocations to the SDO Observatory 
alignment, pointing and jitter budget. The systems, parts, radiation, and 
C&DH team are working closely to investigate radiation-driven parts 
application issues in the Ka-Band science data design, looking at alternate 
parts as well as design mitigation approaches. Finally, the Software team 
has submitted the 1553 interface ICD and is in the process of reviewing 
with the SDO team.

We received the Concept Study Reports (CSRs) from the instrumenters and 
have distributed to appropriated SDO team members for review and 
evaluation. The CSRs represent a significant documentation of instrument 
requirements, plans and management procedures and will be very useful 
references as we prepare contract documentation for the B/C/D/E contract 
phases and SDO confirmation reviews. The instrument systems team is in the 
process of assembling and generating the HMI Instrument ICD and preparing 
for a technical coordination meeting with HMI in late July. The results of 
this effort will provide a significant amount of common content for the 
other instrument ICDs. As Ken mentioned last week, GSFC/NRL/HMI will 
participate in the e2v CCDs and RAL camera electronics peer reviews on July 
16 & 17 in the UK.

The Ground System team submitted a draft copy of the science commanding 
protocol to the Project System Engineers and the spacecraft designers for 
review.

In the area of Configuration Management, the CCR to baseline the Single 
Board Computer SOW was approved this week.

Thanks,
