STATUS/ACCOMPLISHMENTS
The systems team has completed a full draft of the Level 2 Mission 
Requirements Document (MRD) for review by the Instrument and Spacecraft 
Subsystem teams over the next two weeks. In parallel, members of the 
spacecraft team have started to work on preliminary drafts of other 
"cross-cutting" documents like the Electrical Systems Specification and the 
Mechanical Loads and Verification Document.  The mechanical and thermal 
teams continue to evaluate two different mechanical configurations in 
preparation for the System Concept Review.  Recent attention has focused on 
estimating the mass required to properly spin balance both configurations 
for the Delta II third stage compatibility, as well as developing a design 
that provides acceptable fundamental lateral frequencies given the 
relatively small Payload Attach Fitting interface.  In addition, the 
systems team has developed strawman alignment allocations between the 
Instrument and the various Spacecraft Subsystems. This strawman is 
reflected in the draft of the MRD, and an effort will be made over the next 
two weeks to confirm the detailed allocations to each subsystem.

The Project completed a review of the initial grassroots cost & schedule 
estimates and have provided feedback to Product Development Leads's (PDL) 
on their inputs, making sure the assumptions are consistent and agreed 
upon.  By the end of today, we will have conducted the first round of 
detailed discussions with mechanical, software, and flight design.  In 
addition, we are working with the PDLs to create initial draft schedules 
for all spacecraft subsystems (50% complete) and fine tuning the overall 
I&T schedule.  With this information, we have started reviewing product 
need dates to determine procurement time-lines for ordering 
parts/components.  We see the entire grassroots process continuing for the 
next three to four weeks.  Many SDO teams members completed the 3 day 
Contracting Officer's Technical Representative (COTR) training course this 
week.  This enables us to have the needed COTRs for our Instrument 
contracts & the numerous future component & ground system contracts.

The Instrument teams are busy working to provide interface information and 
comments to the Mission Assurance Requirements document all in support of 
our Internal System Requirements Review on Feb. 11 & 12.  The HMI team is 
refining their Instrument optical layout, mechanical packaging, top level 
electrical block diagram, and performing processor trades.  HMI also 
provided copies of their SOHO MDI Instrument Performance Specification to 
show the format expected for HMI.  The NRL SHARPP team is working 
electrical trades and submitted new mechanical models and responses to our 
contamination checklist.  NRL also hired a SHARPP systems engineer, Mike 
Prysby.  To save time & money, NRL is working price options for KCOR 
Instrument optics as part of their existing STEREO SECCHI contracts.  The 
SHARPP team and SDO project will meet in early February with CSL (Leige 
Belgium) to establish working relationships.  The EVE team has their 
subcontract with USC in place & they are in the process of reviewing 
designs & breadboard activities associated with aspects of their 
Instrument.  EVE also delivered a solid works model of their Instrument to 
our Mechanical team.  The GSFC Instrument team will be traveling to Boulder 
to meet with EVE on Jan 21-23.

In the area of Configuration Management, we will have a draft SDO 
Documentation Tree & draft CM procedures out for review next week.  We are 
preparing a document "style" format to assist in writing SDO documents and 
we updated our action item database with the Internal MDR actions.  We also 
continue to make good progress on our Intranet/database.

I welcome Ellen Berkeley (resource analyst), Jerry Klein (risk mgmt. 
coordinator), Ken Vondran (software QA eng. support), & Tom Manson 
(reliability eng. support) to the SDO team.  Their efforts will assist us 
thru the grassroots process & preparation for the SRR/SCR (1st external 
review, week of March 3rd).

In the area of Flight Assurance, we updated the SDO Reliability Block 
Diagram to include a more precise description of the SDO thruster design 
and created  a preliminary fault tree for the thruster system.  Preliminary 
fault trees have also been developed for the EVE and SHARPP instruments.  A 
draft SDO Master Risk List is being created along with a draft of our Risk 
Management procedure which employs & summarizes our draft Risk Mgmt. plan.

Thanks,
Ken
