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 what’s 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%

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 μm 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

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

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
