STATUS/ACCOMPLISHMENTS
We completed our detailed schedules review and our subsystem leads are 
preparing for our first internal monthly status review 
(cost/schedule/technical status).  We also provided additional information 
to GSFC RAO and the IRT for their cost modeling.  This included RAO 
worksheets for the European instrument contributions to SHARPP and TRL 
(Technology Readiness Level) worksheets for all instruments along with a 
detailed breakdown of our avionics to the IRT.

Independent Review Team update:  They are close to having a draft 
assessment & have identified a few areas which we will work with them to 
provide additional information/clarification.  They are still probably 
about 1-2 weeks away from having their independent cost estimate 
complete.  Their work along with our preparations/support may take the 
majority of June which makes scheduling of the management meetings 
difficult due to vacations.  We are currently trying to setup all the 
meetings so that the ICR with the Enterprise PMC occurs the end of 
July.  Code S informed us that our ICR will be at the EPMC and not at the 
Agency Level.  However, the CR will be at the Agency Level.

The systems engineering team has been working with the electrical systems 
team in a comprehensive review of the electrical systems specification in 
preparation for review by the SDO team.  In addition, the weekly SDO 
systems team meeting focused on walking through the current status and 
various options associated with the solar array sizing trade.  As part of 
the monthly Risk Management cycle, the systems team met with the SDO risk 
coordinator to walk through and assess the status of the current risk items 
in preparation for next week's Risk management board, as well as generating 
and evaluating new additions to the SDO risk list.  Finally, further 
definition of the requirements generation and documentation approach was 
ongoing, with the goal of providing a more comprehensive plan and guidance 
to the subsystems teams in their ongoing requirements generation and 
documentation process.  In addition, systems & the GSFC instrument team 
started the discussions on the use and requirements for the baselined 
Spacecraft simulators which will be provided to the instrumenters.

For the instruments, the team completed interface coordination discussion 
with the ACS subsystem group to identify ACS to instrument interface 
requirements and candidate ICD content.  Direct ACS interfacing with the 
instruments is limited, however there is a direct interface with the NRL 
provided Guide Telescopes which needs to be well defined and 
documented.  We are working with the instrumenters to determine appropriate 
areas for initiating early procurement activities for schedule critical and 
long lead items such as mechanism life tests, CCDs, & optics.  All of these 
are documented, coordinated with HQ, & within this budget/phasing. NRL & 
HMI visited e2v & RAL last week in the UK to discuss CCD and camera 
development respectively. The e2v CCD mask design is in process with 
completion and approval set for the second week of July.  NRL, HMI, and 
GSFC representatives will attend the PDR at e2v at that time.  RAL camera 
progress is continuing & we are  evaluating the possibility of HMI 
furnishing the electronic parts to RAL to facilitate camera builds.  The 
Project agreed to the HMI reliability enhancements resulting from a study 
completed by HMI & GSFC.  The enhancements add redundant mechanisms and 
electronics including a second processor to boost the probability of full 
and minimum mission successes.  Both HMI & NRL provided a draft outline of 
the concept study report due at the end of June for comment.

The SDO Mission Assurance Requirements (MAR) document went through its 
initial configuration control board (CCB) meeting with near flying 
colors.  A limited number of action items were identified.  The plan is for 
these items to be completed and modifications incorporated into the MAR by 
next week so that the document can be baselined and placed under 
configuration management (CM) control by week's end.  Wentworth Denoon, the 
Director of Code 300, Office of System Safety and Mission Assurance and I 
will jointly approve the baselined MAR document.

CM & Project Support accomplishments: 1) the team did an excellent job 
preparing for our first CCB with the MAR; 2) continued working action items 
with systems; 3) gathered data from subsystem leads to update the SDO 
housing requirements that were submitted to the LWS Program Office in 
January; 4) started working with modular/systems furniture representative 
to develop a plan for temporary walled offices in Bldg. 29/Room 360; 5) 
updated the Solar Dynamics Observatory (SDO) Project Team Phone List and 
E-mail distribution lists.

Thanks,
Ken
