## 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**

## 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.

## 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.**

## 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.

## 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.

## 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.**

## 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.**

## 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.**
