The SDO systems team continues to work with the subsystems in preparations 
for the upcoming Subsystem PDRs and the Mission PDR. The weekly SDO systems 
meeting focused on the SDO documentation review and configuration process, 
reviewing the document required by PDR and providing clarification as to 
the process and what is expected from each of the document 
originators/submitters and reviewers to get documents approved and under 
CM.  The Systems team released the draft Systems Engineering Management 
Plan for review and is currently updating the SDO Missions Requirements 
Document (MRD) for pre-PDR baseline.  In addition, the systems team is 
currently in the process of reviewing and proving comments to a number of 
mission and subsystem documents included in the PDR-critical documents 
list.  In other areas, the weekly parts team meeting continues to collect 
and evaluate SDO subsystem parts lists.  An updated parts spreadsheet was 
recently completed and the parts and radiation team is the process of 
populating and reviewing the initial parts database.  Finally, the systems 
team participated the monthly Systems Engineering Risk Validation Board 
(SERVB) Meeting, reviewing and updating the SDO Risk List in preparation 
for next week's SDO Risk Management Board Meeting.

For the Spacecraft, the Ka Band subsystem team made progress in 
understanding the process risks of attaching MMIC devices in the Solid 
State Power Amp (SSPA).  An alternate manufacturer process is being 
investigated.  The team has also agreed that a thermal cycle test of the 
SSPA breadboard and a life test of the transmitter is required.  A 
configuration change request was submitted this week for splitting the 
Subsystem Power Node into two cards - a Power Converter Card and a Low 
Power Switch Card.  This change was required due to FPGA power sequencing 
requirements and output common mode filtering.  As a result of this change, 
the ACS, C&DH and GCE boxes will grow by approximately 4 kg in mass and 1 W 
in power.  The Flight Software team has switched their baseline SDN 
operating system from Nucleus to RTEMS.  This switch was made due to data 
sharing protocol advantages of using RTEMS over Nucleus.  In the schedule 
area, the team continues to work detailed plans for the 4/08 launch and the 
Peer Review schedule is becoming less dynamic with most review dates baselined.

For the Instruments, HMI continued its series of Engineering Peer Reviews 
leading up to their Instrument PDR (IPDR) in November.  An HMI Thermal Peer 
Review was held on Wednesday with comments reflected back to the team.  A 
proposed IPDR agenda was created by the HMI team and was forwarded to the 
code 300 lead, Tom Cygnarowicz, for comment after review by the SDO 
team.  EVE submitted updates to the ICD documents in preparation for 
discussions next Tuesday and Wednesday at GSFC.  EVE SDO SCR RFA responses 
are expected next week and will be discussed during the EVE team 
visit.  The EVE team held a Flight Software Engineering Peer Review on 
Wednesday with comments reflected back to the team.  In the area of e2v 
CCDs, we have agreed & started to work on a contractual transition approach 
from NRL to Stanford.  We are waiting on GSFC Legal approval of the letter 
contract to LMSAL for their AIA formulation effort.  We had hoped to have 
this letter contract in place last week, the delay is impacting our PDR effort.

The Ground System team has started weekly Mission Operations Center 
meetings to address/work the interface requirements and the associated 
design parameters affecting our CMD & TLM system (ASIST) development.  The 
Ground System elements are preparing their revised manpower and development 
schedules reflecting the 04/08 launch date which will be complete by the 
end of this month.  The team also held a meeting with the MOMS and NEMS 
contract transition staff to discuss SDO support options.

In the area of CM & Project Support, the team: participated in 
System/Subsystems meetings to address how documents are processed from 
original generation thru the review & release process; started DOORS 
(requirements management) training; updated action items; posted items to 
our intranet site; continues to negotiate GSFC manpower responses; received 
approval from the Facilities Management Division and Logistics Management 
Division for the construction of our new offices in Bldg. 29, Room 360; 
made arrangements for office moves & the arrival of a few new employees.

Thanks,
Ken
