2. Risk Notes: June 2012 • 1) F13 - Phase B Schedule Risk (chart 17):- impact & status need to be reassessed; pending ongoing review/discussions re. the recently received Phase B contract • 2) F3 - Foreign Funding (commitment) (chart 7): - On 5/8 the FIELDS team learned that due to the heavy workload on the RPW/TNR-HFR team and the currently tight schedule fr the RPW/Solar Orbiter, LESIA cannot commit as initially planned for a full development and building of the FIELDS TNR/HFR. • - At that time, the likelihood for risk F3 was increased from a 1 to a 4 • Alternative to TNR/HFR presented on 6/12 and further information received on 7/2. Evaluation of options for how to proceed is ongoing. • - UCB will implement budget/schedule for replacement option by 9/12, bringing risk F3 back to green • Will then open a new technical risk to track the development of the new TNR/HFR option • 3) F8 – Magnetic Sensor/SCM Dynamic Range (chart 11): - Risk Retired. Decision made to sample the MAG faster to cover the gap in frequency

4. FIELDS Phase B Risks Mitigation • FIELDS Risk Mitigation activities for Phase B include: • Antenna Qualification: • Nb materials testing, optical props aging (~Feb to Apr ‘12 TBR(was 3/12), MSFC or EMTL(was Odeillo, France)) • Antenna model thermal testing (~Oct ‘12 to Jan ‘13 (was 3/13), Odeillo, France) • Additional contingency test, if needed (~Oct ‘13, Odeillo, France) • SCM / MAG / FGM Trade: • Determine the optimal technical (dynamic range) & resource (mass and thermal) solution (close by 4/12) • See Trades Slide for additional information. • MAG Performance Over Temperature: • MAG Cold Operations Test (~1/13) • MAG Thermal Cycling Test (end of Phase B) • MAG/SCM Interference: • MAG/SCM Interference test (similar to the MAG/FGM test performed in 7/11) (~5/12 TBR (was 4/13), Chambon, France) • Blue = change since MDR
