Particles and Fields PackageMonthly Status Review (MSR)
March 15, 2011
Dave Curtis, PFP PM
2PFP MSR, 3/15/2011
SSL Contracting Status
• Provided estimated cost (in Phase E) for 5 week transition timeline
3PFP MSR, 3/15/2011
Schedule Status
• EMs have made a lot of progress this month– All EM PWBs in test but ~2 (HVPS boards, in fab)– SEP, LPW, SWEA. MAG mechanical in assembly– STATIC TDC complete acoustics– SWIA/STATIC analyzers final parts out to fab this month
• EM Package I&T starts March 22 with LPW– Pushing to complete before CDR– Instrument calibrations don’t complete till after Package I&T
• Adjusted flight electronics test schedule to reflect reality of limited pool of test engineers– Prioritized testing
• No change to critical path this month– 15 weeks margin to delivery– Achieved by starting flight fab prior to EM test completion for selected
subsystems• Working to improve post-CDR schedule.
– Adjust schedule to take advantage of changes to flight software Build 1 design
• includes less diagnostic code, more code that is useable for Build 2• should get FSW off critical path, improve margin +2-3 weeks.
4PFP MSR, 3/15/2011
Manpower
• RBSP-EFW instrument still not delivered – this month?– All of the people we need have transitioned 100%– Down to final thermal vac test
• Solar Probe Plus is starting to impact a few team members– Adding two new people around the time of CDR to make up for
one retirement and people split with SPP• One from RBSP, one from JDEM
• We are still under planned FTE rate– but climbing a bit– Mostly due to people splitting time between projects– Plan was based on conservative assumptions about covering
people
5PFP MSR, 3/15/2011
Accomplishments
• All PWBs layed out, most loaded and in test– see below
• On schedule for start of Package integration– LPW/PFDPU 3/22– PFDPU/Spacecraft 4/5
• Most EM Mechanical parts are in fab, many delivered– MAG sensor Assembled– SEP, LPW boom, STATIC TDC, SWIA & STATIC MCP mounts in
assembly– Some part-level design work still in progress on SWIA/STATIC
• Last analyzer parts out for fab this month
– STATIC EM TOF Acoustics Test complete successfully– SEP EM attenuator started life test
• SWEA FM analyzer mechanical parts delivered to SSL for plating– Forwarded to the plating house
• More in instrument sections…
6PFP MSR, 3/15/2011
Ongoing Work
• Supporting Project planning process• Supporting EMC, Payload, SDT working groups
• Completing EM board testing• Completing SWIA/STATIC EM mechanical part drawings,
getting parts fabricated• Start PF Package EM I&T, LM EM I&T• Prepare for CDR

Trades, Issues
• HV801 issue still open– Two options: Amptek HV801, Micropac 66353– Amptek delivered some EM HV801s
• Have parts for EM– Current plan is to buy HV801s from LADEE NMS, who has parts
on order they no longer need– Also have an offer of some extra parts from LASP
• Working on an analysis to decide if the PFDPU mechanical design needs to be augmented to support the PWBs to avoid excessive displacements in vibe– MAG EM PWB has option for a center support, others do not– Looks like we can probably eliminate center support, analysis
about ready for review– Analysis Submitted to GSFC– Comparing analysis technique to recent flight history.
10PFP MSR, 3/15/2011
Thermal Status
• Updated Thermal Model delivered– being used by LM to generate thermal environments, due ~3/18
• Provided boom deployment heater power requirement– last of the heater requirements
• Also waiting on deep dip case– Also promised by 3/18

P-01 SSL ManpowerProject

Delays in RBSP leads to manpower conflicts at SSL
Schedule erosion, cost to recover
Near Term
Hire new people to take routine tasks off key personnel

P-07Delayed LPW
Boom Deployment
Mission Performance
1 3 L
Waiting till after MOI to deploy LPW booms results in them sitting undeployed for over a year, increasing the risk of deployment failure
Potential severe degradation of LPW measurement
Far Term
Investigate if LPW booms can be deployed early
Research Early deployment of LPW booms reduces this risk. Actual risk of failure is very low. Risk that we may be asked to do an expensive verification is moderate
P-14 HV801 ProblemProject
Execution1 3 L
If HV801 not available a redesign would be required to use alternate (larger) parts
Schedule, Mass Near Term
Watch what programs ahead of MAVEN do; look into alternate parts
Mitigate Micropak alternate part in test. EM parts found, FM parts identified
P-17Parts
QualificationProject
Execution3 3 M
If parts fail qualification then system would have to be redesigned for alternate (which may also have to be qualified and may have lower performance)
Schedule, Cost, Performance
Near Term
Start parts qualification as soon as possible (but delayed to FY11 for funding)
Mitigate First round of parts radiation testing started. SEL test results look good
P-18Magnetics

fabricated before additional EM carbon foils are loaded• Preamp part changes needed to reduce the gain for optimal dynamic
range• EM HV Sweep partially loaded – waiting on shield boards (in fab)• EM 15kV-MCP board partly loaded - waiting on MCP “stack stick”
multiplier to return from paryline coating• Waiting on second EM preamp with component changes to optimize
gain (improve dynamic range)• Analyzer and mechanical attenuator still in development• Manipulator fixtures for calibration in development• Some test harnesses and test cables still on order• New calibration chamber ordered – delivery late May• Additional equipment for clean-room 320 ordered (cabinets, tables, etc) • Clean-room portable sink in development

MAVEN PFP SEP Status
March, 2011
Davin Larson, SEP Lead
38PFP MSR, 3/15/2011
SEP Accomplishments2011-03-09
• Mechanical attenuator tests started. – First testing using GSE (MISG) – GSE working – but has occasional dropouts (see below).– Initial assembly had micro-switch mis-aligned which resulted in failure on first overnight test
because attenuator got caught in a position with both switches open.– Micro-switches re-aligned, ready for retest.– Resolved questions about plunger force.– Performed 24 hour (1000 cycle) test in air. Successfully completed 972/1000 cycles. Failure
determined due to loss of TCP/IP connection of MISG – not due to ETU.– Actuator duration vs voltage test in air performed.– First life cycle test in vacuum was incomplete due to MISG disconnects. (~2000 cycles were
completed)– Second life cycle test started on 03/09
• ETU Silicon detectors are diced and tested. However delivery is overdue (Craig Tindall has been sick). Flight detectors are a few weeks away.
• DAP board– Stuffed with parts (2 channels only) All parts now installed. – Actel programing delivered, burned and inserted.– Testing underway:
• Discovered that test pulsers is NOT operating properly due to change from 5V actel to 3.5V actel.• Minor x2 error in pulser frequency discrepancy in FPGA (could just change the documentation)
• All Mechanical parts have arrived. (Baffles finally arrived)• DFE light tight Test box/cable in assembly (rework actually)

FSW QA
• Held a telecon with NASA QA to address differences between NASA Software Assurance Plan and SSL Software Development Plan.– Resulted in a rev to the SAP– Still have a few questions about interpretation, but we are close.
• Waiting word from Project on how to deal with 7150.2 CMMI issue.
