  5. IPDR resulted in Total RFAs: 29 received EFW instrument RFAs 20 received 20 in 19 concurred EFW SOC RFAs 5 received 0 in Project RFAs 4 received 2 in 2 concurred MPDR produced no EFW RFAs RFAs/AIs from earlier reviews

  6. Sparing plan In general, fully qualified flight spares are not required and are not being built for RBSP/EFW Limited sparing is being done where it makes sense A flight spare DFB board will be built Flight spare electronic parts will be obtained but not assembled in the cases of the DCB, BEB and LVPS Flight spare mechanisms will be built but not fully qualified in order to save money Should spare or replacement components be needed, we would assemble and qualify as required

  7. Critical Facilities Facilities at LASP LASP cleanrooms, assembly and test areas are ready to go and will be available throughout the flight hardware fabrication program Facilities at UCB UCB cleanrooms, assembly and test areas are ready to go and will be available through the flight hardware fabrication, testing and qualification program This includes appropriate vacuum chambers for all TV configurations Vibration testing will be done at a contractor in the bay area EMC testing will be done at a contractor in the bay area

  8. Staffing Personnel at LASP LASP personnel are certified as needed and ready to go throughout the fabrication and testing period Personnel at UCB UCB personnel are certified as needed and ready to go throughout the fabrication, testing and qualification program Workforce risk Both UCB and LASP have other programs ramping up in the near future Other programs could infringe on EFW personnel making it difficult to find the appropriate skill mix at the required time Mitigation has been to add personnel where possible Mitigation is also to move forward with the fabrication of flight hardware well in advance of the mission CDR

  9. Deliverables Instrument Requirements Document – baseline (SE-001-001C) Deviations/Waivers (CM-002-004) Performance Assurance Matrix – update (MA-001-001C) GSE Interface FMEA – baseline (MA-002-007A) Limited Life Items List – baseline (MA-002-009B) As-Designed Parts List (MA-005-002B) Spares List – baseline (MS-006-001) Long Lead Items List – as applicable (MS-006-002) CMD/TLM Definitions – preliminary (SE-005-001B) Instrument User’s Manual Information – preliminary (SE-006-001A) As-Designed Materials and Processes List – (SE-007-009B) Software Requirements Document – baseline (SW-002-001B) Software Integration, Verification and Test Plans – preliminary (SW-005) Instrument Verification & Validation Plan – preliminary (TE-001-002A) Test Plan Inputs for S/C I&T – baseline (TE-004-001B) Instrument Test and Calibration Plan – preliminary (TE-001-002A) Indentured Drawing List – baseline (CM-002-001B) Top Level Assembly Drawing – baseline (CM-002-002B) Drawings & Schematics – baseline (CM-002-003B) Instrument to spacecraft ICD - draft (SE-002-001D) Contamination Control Plan (SE-008)

  10. Deliverables - Periodic Monthly progress Monthly schedules EFW master integrates all activity Mechanical Electrical LASP I&T Monthly financial (533M & 533Q) Monthly EV tracking and analysis Quarterly status

  11. Performance to Date Phase C use of funding reserve $1,381k was the the EFW held reserve at the start of phase C Project holds a similar amount on our behalf Since then, we have made or will make use of some reserve funding $140k LVPS redesign $53k Vibration force limiting $20k LVPS parts $120k DIN96 replacement $20k Frangibolt switches $353k of $1,381k which is 25% of local reserve

  12. Reserve to Delivery Reserve was set to 20 days and then increased to 46 (required) Reserve will not be touched… Slack is adjusted monthly to match critical path In April, issues pushed iCDR out, reduced slack LVPS DIN96 AXB tuning

  13. Slack used to iCDR Booms started out on the critical path LVPS issue developed in April, iCDR slipped in May LVPS correction was slow through the summer AXB tuning used Boom slack in the summer

  14. Schedule Into the future Critical path going forward is AXB development Due to a series of environmental tests Following that, the SPB development is next on the CP Long lead parts are mostly in hand A few stragglers are due in December Designs are in good shape Drawings are being released for flight fab EM development success will lead to FM development on time and on budget Cost projections, based on past projects and the EFW EM program suggest we’re within our cost envelope Original C/D EV budget was $12,707k Current C/D EV EAC is $12,593k

  24. E-05 AXB Shadowing We expect the aft AXB to be shadowed by the S/C body. Requirements allow this but science return would be improved if the AXBs can be in sunlight. To this end, we’ll be prepared to deploy up to 7m of AXB if S/C stability observations allow it. E-25 DFB FPGA Verification Verification of the FPGA code has lagged. Manpower has been added. E-23 LVPS Immature LVPS implementation is new and not as far along as it could be. Added manpower has been focused on this issue. E-18 NTE Power CBE power estimates are edging up to NTE. Power uncertainty is not yet low enough to dismiss. Project accepts the likelihood of a small increase to our NTE. E-14 Flight Hardware Delayed Other SSL projects could make it hard to get the appropriate skill mix in the appropriate time frame for FM fabrication and I&T. Pushing forward to complete fabs. Adding manpower. E-26 Peek Charging Small amounts of peek are scattered throughout deployment mechanisms. If changes are needed, they must come soon. Risk specifics
