MRRIMAGE IMAGE MRR 2/14/00RJB/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

MRRIMAGE IMAGE MRR 2/14/00RJB/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.

MRRIMAGE IMAGE MRR 2/14/00RJB/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.

MRRIMAGE IMAGE MRR 2/14/00RJB/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.

MRRIMAGE IMAGE MRR 2/14/00RJB/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.

MRRIMAGE IMAGE MRR 2/14/00RJB/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.

MRRIMAGE IMAGE MRR 2/14/00RJB/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.

MRRIMAGE IMAGE MRR 2/14/00RJB/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 and DTF-21 at JPL, 2/99, 5/99, 9/99 (Retest for Transponder fix), ! 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.
