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.

4. 4 PFP 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

38. 38 PFP MSR, 3/15/2011 SEP Accomplishments 2011-03-09 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)
