The Spacecraft/Orbiter and Instrument teams responded with their Performance Assurance Implementation Plans (PAIP) which outline how the individual institutions and their contractors would meet the requirements called out as CDRLs in the MAR. After the project has reviewed the initial PAIPs and commented back to the teams, revisions in the PAIPs may be required. Those requirements which the developers cannot meet will be documented on a waiver request. NASA’s Goddard Space Flight Center 24a - 6 Problem Failure Reporting • • • • • Both the spacecraft/orbiter and instrument teams are required to document failures (at the first application of power at the start of end item acceptance testing or the first operation of a mechanism) or nonconformances with received product. The LRO project office must be notified of problem/failures within 24 hours of occurrence. A failure review board may be required to disposition the actions related to the issue. A closed loop nonconformance system is also required by the MAR. It shall include ensuring the corrective action is implemented to prevent recurrence. A Material Review Board is required to disposition other than preliminary reviews. The teams QA lead shall be a member of the MRB. The MRB chairperson shall notify the LRO project of all MRB actions and recommendations. NASA’s Goddard Space Flight Center 24a - 7 Surveillance and Audits • • • • The LRO Project has a surveillance plan (430-PLAN-0003) which defines how the project will monitor hardware and software development activities from all the contractors. Assurance reviews and audits provide an insight into how the contractors are functioning. Participation by SMA in boards such as CCB, PCB, MRB, FRB and others provides insight into various phases of the design and workmanship. The LRO SMA team will use two methods of product verification. – Direct examination: inspection of hardware and associated documentation – Indirect examination: similar hardware fabricated by the same personnel and equipment, lot acceptance samples and material examinations that may take place at GSFC. NASA’s Goddard Space Flight Center 24a - 8 Mission Assurance Summary • Mission Assurance Requirements are well defined and comprehensive. • These are traditional requirements for GSFC Missions and they are understood. • Systems with experienced personnel are in place and operating. The Lunar Reconnaissance Orbiter Mission Assurance team is ready to support PDR NASA’s Goddard Space Flight Center 24a - 9
