STATUS/ACCOMPLISHMENTS
The SDO GN&C team provided a Reaction Wheel make/buy trade assessment. The 
assessment included a thorough analysis of requirements and a comparison of 
candidate hardware performance, cost, and schedule.  The make/buy decision 
will be made in the near future, pending receipt of additional vendor 
information.  The Subsystem Data Node (SDN) team completed layout of the 
SDN prototype board. The prototype boards are now being fabricated and the 
parts kitting is in process with assembly beginning in a couple of weeks.

For the Instruments, we reviewed the revised MIT Lincoln Labs SOW for the 
EVE CCD development work and provided comments to EVE.  We intend to 
provide funds for an early start of this work and we are in the process of 
generating a CCR to mod the EVE SOW accordingly.  We held an accommodations 
coordination meeting with SHARPP to consider and discuss placement 
requirements for SHARPP's KCOR, CCD electronics box, relocation of KCOR and 
AIA (Atmospheric Imaging Assembly) mounting feet, and a repackaging of the 
SHARPP main electronics box to satisfy SDO volume and connector/harnessing 
restrictions and proximity requirements for SHARPP's mechanism drivers.  We 
also conducted a weekly telecon with the instrumenters to go over 
high-speed bus design decisions and associated physical and functional 
interface requirements.

The ground system received 8 responses from industry regarding the RFI for 
decoders and receivers. One company in particular has a viterbi decoder all 
on a single board.  If our analysis is proves out then the ground system 
will purchase this item rather than build it.  An RFI was also issued to 
seek industry input on the state of technology for Network Storage 
Devices.  We continue working towards determining if command encryption is 
necessary for SDO.  The Ground System team has developed a draft fault tree 
analysis (for subsystem review) that identifies high, medium, and low risk 
areas. The team is also making good progress refining schedules and 
documenting detailed mission & interface requirements.

In the area of CM & Project Support, the team provided document/drawing 
numbers, updated the document tree, started testing portions of our 
internal intranet database, distributed 2 CCRs for review/comments in 
preparation for next week's CCB meeting, released updated mass budget, and 
reviewed/generated comments on 400-PG-1410.1.1A (Directives Management for 
Flight Programs and Projects), 400-PG-1410.1.2B (Configuration Control), 
and GPG 7120.1B (Program and Project Management).  We are also working with 
other Bldg. 29 occupants to discuss their schedules for vacating cubicles 
in Bldg. 29/Room 360 so that SDO may occupy the space when available.

Thanks,
Ken
