7. Requirements and Safety Flow-Down of MAIP Requirements SSL, LASP, CESR, GSFC Deviations Materials and Processes requirements, Section 6 of MAIP Compliance deviations are documented in the MAR checklist System Safety Personnel, facility, and mission safety have been considered. The Safety Plan has been generated and is in review MAVEN_PF_QA_005B_Safety Plan and MAIP section 4 The safety plan identifies all requirements, planned tailoring approaches, intended non-compliances, and safety data submittals have been identified. There are no safety compliance issues.

8. Suppliers and Alerts Suppliers SSL procures all active EEE flight parts from GSFC SSL procures passive EEE parts directly from the manufacturer or through authorized distributors. SSL requires full traceability on all flight procurements. Program requirements are flowed through procurement documentation. Where necessary, procurement documentation may include source control documents (SCDs) and engineering documentation. GIDEP Status SSL will respond to GSFC GIDEP evaluation requests There are no current GIDEP impacts – no parts on MAVEN are currently impacted by any Alert or Advisory. Other Memos and Alerts will be Incorporated, for example: “The use of brominated polyimide is unacceptable” (Polyimide board material)

19. PFP PFR Process

20. Fault Tree Analysis MAVEN_PF_QA_004 Fault Tree Analysis submitted to Project Fault Tree based on ‘Instrument Resiliency’ analysis by PI (which flows out of Level 1 requirements) Mixture of redundancy (PFDPU, MAG) and the ability to meet mission objectives with backup measurements from other instruments leads to few critical faults STATIC is the only component whose failure would result in loss of a mission objective

21. PFP Fault Tree

22. PFP FMEA MAVEN_PF_QA_007 FMEA / CIL/ CICP submitted to Project Component-level FMEA performed on PFP, concentrating on the interfaces A total of 78 failure mechanisms were analyzed No Criticality 1 failure modes found Several criticality level 2R failure modes Only STATIC had 2 critical failures modes STATIC was analyzed down to the subsystem level An additional 22 failure modes were analyzed Puts STATIC is on the Critical Items List for PFP A second STATIC was considered, but there were insufficient project resources to accommodate it
