PFP Responsibilities MAVEN PFP ICDR May 23 -25, 2011 1 -6

Contracting • Phase C/D Contracts in place – SSL and LASP/LPW independently contracted to GSFC for MAVEN PFP – Internal Funds Transfers from MAVEN Project to GSFC/MAG – IRAP/SWEA funded by CNES, contributed hardware to SSL • IRAP formerly CESR – Inter-agency agreement with Lawrence Berkeley Nartional Labs for SEP detector development • SSL Manages PFP development in collaboration with MAVEN Project Office – SSL Coordinates PFP Team • Schedules, Planning, Interfaces, Technical Resources, Risk Management, etc. – A common Instrument Manager at GSFC facilitates coordination of contracts, deliverables, funding, etc. • No changes in this configuration since PDR MAVEN PFP ICDR May 23 -25, 2011 1 -7

Team Experience • SSL has a long history of successful development of instrument suites: – Wind 3 DP (5), FAST (5), MO/MGS/LP MAG/ER (2), STEREO IMPACT (7*2), THEMIS (5*5) • Team is experienced working together: – SSL w/ GSFC, Acuna/Connerney, MAG: MO, MGS, LP, STEREO – SSL w/ LASP, Ergun, LPW: FAST, THEMIS – SSL w/IRAP/CESR, Reme/Sauvaud/Mazelle, ESAs: Giotto RPA, Wind 3 DP, Cluster CIS, MO/MGS MAG/ER, STEREO IMPACT SWEA – SSL w/ Lockheed Spacecraft: MGS, LP • Centuries of experience building spaceflight instrumentation in the PFP team • No changes in the team key players since PDR – some additions at lower levels MAVEN PFP ICDR May 23 -25, 2011 1 -8

Staffing • PFP Team fully staffed – Consistent below planned FTE levels due to: • RBSP issues which have pulled MAVEN team members away • Shared staffing with other projects, resulting in unplanned efficiencies – Some team members have been distracted by continuing responsibilities with RBSP EFW instruments • SWIA/STATIC mechanical engineers • Power converter design team • Thermal engineer – Work-arounds have had some success • but SWIA/STATIC behind schedule in completing EM fabrication and test • SWIA and STATIC still have plenty of schedule margin to delivery MAVEN PFP ICDR May 23 -25, 2011 1 -9

Schedule Summary, CDR to Delivery MAVEN PFP ICDR May 23 -25, 2011 1 -27

Schedule Margins • FM Instrument deliveries to PFP Integration margin – MAG – 7. 4 weeks (was 12. 4 weeks at PDR) – LPW – 8. 2 weeks (was 11. 4 weeks at PDR) • Includes 2. 2 weeks to delivery from LASP plus 6 weeks to Package I&T – – – SEP – 10. 4 weeks (same as PDR) SWEA – 9. 4 weeks (was 11. 4 weeks at PDR) SWIA – 9. 8 weeks (was 10. 4 weeks at PDR) STATIC – 7. 4 weeks (was 10. 4 weeks at PDR) PFDPU – 9 weeks (was 11. 4 weeks at PDR) • PFP Integration to Ship margin – 10. 6 weeks – increased from 4 weeks at PDR due to later delivery requirement • So 18 weeks total margin CDR-Delivery on the critical path – Was 14. 4 weeks at PDR (plus 4. 4 weeks pre-CDR margin) – Out of 16 months – Critical Path currently through STATIC due to delays in completing EM fab & test • All schedule margin/slack is funded MAVEN PFP ICDR May 23 -25, 2011 1 -28

Schedule Status • Some instrument EM assembly/test still to be completed • • 18 of 28 parts stress analyses still to be completed Detailed Board-level thermal analysis remain to be completed for all boards dissipating significant power (>0. 5 W) including: – Especially SWIA, STATIC – Includes SWIA/STATIC Attenuator life test, instrument calibrations – Includes STATIC ‘Worst Case Test’ voltage-temperature margin test – REG, IIB, DCB, DAP; SWIA Preamp, Power converters; STATIC Digital, TDC, Power Converters • • Feedback from EM testing to power converter requirements not complete Full-up PFP integrated package test • • PFDPU board mechanical PWB stress analysis to be finalized All of this will be completed and results delivered by Mission CDR with the following exceptions: • – Have completed all individual instrument to PFDPU integration, just not all at once – SWIA, STATIC Calibrations – SWIA, STATIC Attenuator Life test – These will be completed by mid August FM schedule assumes flight build not started until these tasks are completed on an instrument-by-instrument basis – i. e. SEP can start flight fab even though STATIC is not done with calibration MAVEN PFP ICDR May 23 -25, 2011 1 -29

Drawing Status • EM Drawings nearly 100% complete – Missing: • MAG Thermal blanket, assembly drawing • PFDPU mechanical (pending MDM connector change) • PFDPU Flight-format FPGA daughter board layout (in review) • The majority of EM drawings will be converted to FM drawings with some minor exceptions as a result of EM assembly and test – FM Drawing release pending completion of EM testing in most cases MAVEN PFP ICDR May 23 -25, 2011 1 -30
