Mars Atmosphere and Volatile Evolutio N MAVEN Mission

Mars Atmosphere and Volatile Evolutio. N (MAVEN) Mission Particles and Fields Package Pre-Ship Review October 30, 31, 2012 08: Verification Dave Curtis MAVEN IPSR October 30, 31, 2012 1 -1

Requirements Management • PFP Flight System Requirements at Level 3 (excluding Mission Assurance): – PFP Functional Requirements Document, MAVEN-PFIS-RQMT-0016 – PFP to Spacecraft ICD, MAVEN-SC-ICD-0007 – Environmental Requirements Document, MAVEN-SYS-RQMT-0010 • Requirements are managed by PFP in Excel and transferred to/from DOORS by MAVEN Project – Coordinated with LM for ICD Requirements • Requirements are flowed down to the instruments and subsystems, but final verification is reported (and often verified) at Level 3 – When a lower-level verification is the final verification for a requirement, that verification is formally mapped to the Level 3 requirement, and the verification documentation is included • Requirements documents are current to all design changes and have been mapped into the Verification Matrix MAVEN IPSR October 30, 31, 2012 1 -2

Verification Documents • PFP Verification Plan MAVEN_PF_SYS_023 • PFP I&T Plan MAVEN_PF_SYS_022 • PFP Verification Matrix MAVEN_PF_SYS_033 – ERD verification reviewed by Project – ICD instrument verifications agreed with LM – LASP/LPW, GSFC/MAG and IRAP/SWEA Verifications included • Verification Reports – Posted here (and also on MIS): – ftp: //apollo. ssl. berkeley. edu/pub/MAVEN/Test.

Functional Requirements Pending • 34/107 complete • 29 pending FSW test completion / AR – This week • 19 pending Package I&T • 15 pending completion of calibrations – SWEA, STATIC – Tentatively verified in pre-environmental calibrations • 10 relate to open ERD or ICD requirements • All will be complete by delivery MAVEN IPSR October 30, 31, 2012 1 -6

ERD Requirements • 58/106 complete • 40 pending incomplete environments – Note that until all components have completed an environmental test such as thermal vac, can’t take credit for any requirements related to that test. – Pending completion of SWEA, STATIC environments • 8 pending final MICD inspection of components • All will be complete by delivery MAVEN IPSR October 30, 31, 2012 1 -7

ICD Requirements • 64 out of 142 complete • 22 pending FSW test completion / AR – This week • • 5 pending Package I&T 15 pending component MICD inspections 22 pending completion of pointing analyses 9 pending completion of environments – Mass properties, etc. • All will be complete by delivery MAVEN IPSR October 30, 31, 2012 1 -8

Verifications at ATLO • None of the requirements allocated to PFP are expected to be open at delivery • A few requirements were deferred by plan to ATLO – – – Spacecraft Interfaces (with actual spacecraft) Shock (except self-shock) Acoustics (except STATIC) Observatory EMI self-compatibility (did EMC tests) Spacecraft Magnetics Verification (did component characterization) – Accumulated operational hours (deliver to ATLO with ~200 hours) MAVEN IPSR October 30, 31, 2012 1 -9
