Project Wide Meeting Open to the team at large. Intent is to provide a forum for information to flow from the Project as well as the Program Office and NASA/HQ-SMD. Provide high-level insight into the investigations. Opportunity to ask questions. 3 Slide 4 Solar Probe Plus A NASA Mission to Touch the Sun Solar Probe Plus Project Wide Monthly Oct 2012 Near and Future Happenings Near Term Happenings:. Semi-Annual NASA-HQ Review: 9 Oct 2012 Quarterly Reviews/EVM Road Shows: WISPR: completed SWEAP: Quarterly complete, EVM: 29 Oct 2012 FIELDS: 15 Nov 2012 (Quarterly and EVM) ISIS: 17/25 Oct 2012 (Quarterly/EVM) Far (and very far) Term Happenings Mid-Phase B SRB Status Update: 13 Feb 2012 (tentative) EVM Pilot Program starts: Mar 2013 C/D Proposal Activities: July 2013 4 Slide 5 Solar Probe Plus A NASA Mission to Touch the Sun Solar Probe Plus Project Wide Monthly Oct 2012 Area of General Concern Invoicing (cost) variances are have grown and then stabilized. * Numbers are cumulative ** Spacecraft discrepancies are mostly due to spacecraft subcontracts Aug/Sept data new since last Project Wide Monthly However: Phase B is >32% complete. Trends appear to be stabilizing. Started regular monthly subcontracts meetings to review cost vs. plan Question: How much of the deficit is under-spending and whats the plan to make up for it? 5 NASA WBS ItemMayJunJulAugSep 5.0Payload/Instruments2%-14%-37%-53%-49% 6.0Spacecraft-14%-12%-24%-23%-25% Slide 6 Solar Probe Plus A NASA Mission to Touch the Sun Solar Probe Plus Project Wide Monthly Oct 2012 Top 10 Risk Matrix 6 Changes since last month: SPP-23, PSE model for hardware in the loop simulator closed on 9/6/2012 SPP-24, Redundant Electronics Module (REM), Redundant Process Model (RPM) breadboard for the hardware in the loop simulator closed on 9/6/2012 SPP-29, Upper Stage Staff Support mitigation steps have been completed, this risk was accepted on 9/6/2012 SPP-46, ASIC ECU vs. Standard ECU closed on 9/6/2012 SPP-49, Availability of Goddard TVAC 238 Facility closed on 9/20/2012 Slide 7 Solar Probe Plus A NASA Mission to Touch the Sun Solar Probe Plus Project Wide Monthly Oct 2012 7 Mass and Power Trends * Power margin is minimum margin for driving configurations Slide 8 Solar Probe Plus A NASA Mission to Touch the Sun Solar Probe Plus Project Wide Monthly Oct 2012 8 SPP Critical Path Slide 9 Solar Probe Plus A NASA Mission to Touch the Sun Solar Probe Plus Project Wide Monthly Oct 2012 Action Item Burndown 9 Slide 10 10 ISIS Status Update EPI-Hi: LBNL (diode fabrication) and Caltech (thinning) received first prototypes made with flight processes preliminary tests (I vs V, C vs V, alpha particle response) look reasonable prototype detectors with 15 m active thickness to be tested in detail at Caltech EPI-Lo: Quadrant vs. Octant Testing Designed and build octant and quadrant versions of anodes Preliminary testing shows similar performance for both boards Confirms baseline design is sufficient Slide 11 Technical meeting held at MSFC to prepare for SPC beam tests in Solar Wind Facility High voltage SPC cable prototype characterized in vacuum furnace First IMAX projectors and optics bench arrived at SAO for installation in front of vacuum chamber (Solar Environment Simulator) Aluminum version of SPC Thermal Test Model 1 (TTM-1) assembled, fabrication started on version with high temperature materials SWEAP September Activity Highlights - Requirements, prototypes for key electronics in SPAN, SWEM, SPC - Planning for operations, flight, and ground software - SPC TRL6 Activities Slide 12 Slide 13 WISPR status Phase B risk reduction and preliminary design proceeding as planned Attended joint SPP-SO splinter session at the 5 th Solar Orbiter Workshop in Brugge, Belgium Completed trade study on electronics architecture for the WISPR IDPU Maintain baseline in which APL will provide the IDPU to interface with the WISPR camera electronics Procured glass samples for dust impact testing at MPI for Nuclear Physics, Heidelberg from October 15 25 Test will validate dust impact and stray light modeling carried out by APL and NRL Results will inform project-level decision on single telescope versus two-telescope design trade 092712_WISPR_Quarterly Review 13 Slide 14 Solar Probe Plus A NASA Mission to Touch the Sun Solar Probe Plus Project Wide Monthly Oct 2012 Questions?? 14
