IMAGE GS Readiness: FOT Training MRR !All FOT have been on staff since before Payload I&T began. !All FOT had prior mission experience. !All FOT have rotated between R/T Analyst and Command Controller. !All FOT have worked as P/L Test Conductors. !All FOT have received Hands-On training from SI’s & CIDP as P/L TC’s !All FOT have received formal training from LMMS as well as OJT. !All FOT have participated in development of documentation. !All FOT have participated in development of the ODB. !FOT have been sole Payload Operators since 2/99 !FOT have been operating S/C since Compat-Test 1 in 2/99. !FOT hours in command of Observatory approx. 50 days. !Payload and Observatory I&T systems are also used for Operations 2/14/00 IMAGE MRR 6

IMAGE Operations: Staffing MRR !FOT has been at full staff (5) since 11/98. !FOT will downsize during transition to Automated Ops after IOC, to 2. 5 Operators and will remain there until EOM. !Transition Planned for Launch + 60 days, only when Lights Out Concept has been validated. !GSM/MD (Burley) and MOM (Gustafson) are backup operators during IOC. !IOC will be staffed at 2 shifts per day, 12 hours per shift. – 2/14/00 Note that during our spin-up periods we switch from ‘contiguous’ DSN coverage to a single pass per orbit. This will provide some relief to FOT. IMAGE MRR 7

IMAGE Operations: Contingency MRR !32 Contingency Plans have been identified and documented. tested with the Spacecraft or verified by analysis. All have been !Observatory Health and Safety is monitored by ASIST, which alerts FOT via Skytel paging network via the SERS system. !SMOC provides L 0 data and can flow real-time or recorded telemetry to remote instrumenters, LMMS Engineers & Sw. RI Engineers for troubleshooting. !All mission critical SMOC systems have backup hardware. !Mission Data is backed up in multiple locations (JPL, FEDS, DHDS, NSSDC). !FSW Maintenance: – – – 2/14/00 Sw. RI provides FSW Maintenance of CIDP. LMMS provides FSW Maintenance of SCU s/w on a sustaining engineering contract to Sw. RI. SI’s provide FSW Maintenance for their instruments. IMAGE MRR 10

IMAGE SOMO Readiness: Facilities MRR !Critical IMAGE facilities at GSFC include the SMOC (B 3 Rm. S 25 E/D) and data communications h/w in B 3, B 14 and B 1. ! All these facilities are physically secure with power backups. ! Facilities Division has no activities planned which could interrupt service. ! Work Freeze will be implemented around these facilities at L-6 hours. 2/14/00 IMAGE MRR 13

IMAGE SOMO Readiness: NISN MRR !All Voice lines are in place and tested. !All Data lines are in place and tested. !Network Security Manager and Officer delegated. !Network Security Plan approved and in place. Officer named. Network Security Manager and !NISN/NASCOM has no activities planned which could impact IMAGE Readiness. 2/14/00 IMAGE MRR 14

IMAGE SOMO Readiness: DSN MRR !IMAGE is in DSN scheduling system, and is projected to receive all requested support. !Extensive compatibility tests between IMAGE and DSN/CTT have been successfully conducted on 8/98 (Transponder-only@JPL), and DTF-21 at JPL, 2/99, 5/99, 9/99 (Retest for Transponder fix), 12/99, 1/11@WR. !Mission Readiness Tests have been run from all DSN sites during all shifts with data flows going to/from the IMAGE/SMOC at GSFC. !Operations agreement regarding communication between SMOC and JPL during lights out passes is nearing signature. !Implementation of 26 m-subnet automation is now scheduled to occur during IMAGE IOC. DSN schedulers believe that this can be done with minimal to zero impact to IMAGE can/will remain on existing system. !Internal JPL/DSN Launch Readiness Review successfully held on January 31. 2/14/00 IMAGE MRR 15
