6. GS Readiness: FOT Training • 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

7. Operations: Staffing • 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. • 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.

8. Operations: IOC Overview • First pass on DSS-66 at 22 minutes after separation. • Re-Orient observatory spin axis on days 1 through 8. Open instrument doors to facilitate out-gassing. Perform Spacecraft checkout, and LV SFF on several instruments. Power FUV/GEO. Switch from OMNI to Helix antennae when re-orientation complete. • Spin up to 13 RPM on days 8 through 16. • Deploy RPI radial antenna to 120 m on day 16. Conduct MENA LV SFF and open MENA shutters. • Spin up to 1.4 RPM on days 17 through 20. • Deploy RPI radial antenna to 160 m on day 20. • Spin up to 0.96 RPM on days 21 through 24. Ramp EUV HV to Sun-Safe. Ramp FUV to Science Level. • Deploy RPI radial antenna to 210 m on day 24. • Spin up to 0.75 on days 25 through 33. Open HENA Shutter. • Deploy RPI radial antennae to 250 m on day 35. Deploy RPI axial antennae. • Ramp-up high voltage on Science Instruments on days 36 through 39. • Begin Nominal Operations on day 40.

9. Operations: Nominal Ops • Automated Functions include: • Nominal Pass Execution. • Observatory Health and Safety limit checking. • Level Zero Processing. • Execution of Science Data Processing scripts. • Manual Functions include: • Weekly Command Pass Execution, including receipt of weekly science stored commands from PI and preparation of stored spacecraft commands. • Weekly validation of onboard-derived attitude. • Weekly system backups and Network Security Monitoring. • Analysis of Trend Data. • DVD Generation. • Anomaly Resolution.

10. Operations: Contingency • 32 Contingency Plans have been identified and documented. All have been tested with the Spacecraft or verified by analysis. • Observatory Health and Safety is monitored by ASIST, which alerts FOT via Skytel paging network via the SERS system. • SMOC provides L0 data and can flow real-time or recorded telemetry to remote instrumenters, LMMS Engineers & SwRI 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: • SwRI provides FSW Maintenance of CIDP. • LMMS provides FSW Maintenance of SCU s/w on a sustaining engineering contract to SwRI. • SI’s provide FSW Maintenance for their instruments.

11. GS Documentation & Reviews • Signed Documents: • PSLA, DMR, GSIP, MRP, Security Plan, S/C Users Guide, S/C Operators Training Manual, S/C T&C Handbook, IMAGE/NSSDC MOU. • Documents out for Signature: • IOC Plan, Contingency Plans, Flight Procedures Document, Launch Site Operations Plan, Configuration Management Plan, DSN Operations Agreement. • Pending Documents: • Mission Ops Plan • FOR held on 11/9/99 • 10 RFA’s submitted, All closed. • ORR held on 12/23/99 • No RFA’s generated

13. SOMO Readiness: Facilities • Critical IMAGE facilities at GSFC include the SMOC (B3 RmS25E/D) and data communications h/w in B3, B14 and B1. • 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.

14. SOMO Readiness: NISN • 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. Network Security Manager and Officer named. • NISN/NASCOM has no activities planned which could impact IMAGE Readiness.

15. SOMO Readiness: DSN • 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 26m-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. IMAGE can/will remain on existing system. • Internal JPL/DSN Launch Readiness Review successfully held on January 31.
