STATUS/ACCOMPLISHMENTS
The systems team has been holding detailed meetings and telecons with the 
Instrument and subsystem teams to get their inputs to the SDO Mission 
Requirements Document (MRD), which details the SDO Level 2 mission 
requirements and their traceability. These comments have been reviewed and 
folded back into the MRD and re-released Thursday (2/6) to the entire SDO 
team in preparation the Systems Requirements Retreat (SRR) to be held Feb 
11-12.  The systems team has also been planning the upcoming SRR 
presentations, as well as the technical splinter meetings planned with the 
subsystem and instrument teams. As part of the SRR, the systems team has 
planned a detailed walk-through of the MRD requirements to review their 
accuracy, traceability, and allocation with the entire assembled SDO 
team.  In addition, the technical splinter meetings will highlight specific 
technical issues that need further definition and coordination between the 
SDO spacecraft and instrument teams.  In addition, the systems team has 
been working closely with the subsystem leads to develop an updated 
spacecraft bus concept that reflects the recent launch vehicle decision 
from Code S.  Preliminary details of any design changes are planned to be 
presented as part of the technical splinter meetings in the SRR.

The SDO Ground System Team and key members of each SOC completed it's final 
field visit and assessment of the WSC (White Sands Complex).  We also 
received the formal "SDO Ground System Link Analysis" of WSC and Wallops 
performed by Code 450 and ITT Engineering Industries.  WSC rated very well 
for our SDO application, but Wallops did not rate as well based on weather 
and infrastructure capabilities.  A formal letter of request will be 
submitted through Code 450 to the Johnson Space Center to reserve two 
antenna pad locations and approximately 800 sqft in building T1, room 
150.  The Ground System Manager is also preparing an SDO Mission Overview 
presentation for the Code 580 management team (2/19).  Included in this 
presentation will be a call for civil servant support for the purpose of 
retaining core CS competency at the center level.

Thanks,
Ken
