## Range Processing

***Range Processing***

***Astrotech***
***All post-ship activities***
***Fueling and DPAF activities***
***Office Space***
***SLC-2W***
***Launch from this pad with SAC-C***
***Level 5 & 6 used during pad activities***
***All pad activities coordinated with Boeing***
***Bldg. 836***
***Launch ground station to be located here***

## Range Procedures

***Range Procedures***

***I&T Procedures***
***Existing I&T procedures utilized to maximum extent possible***
***Most procedures have been reviewed and approved by NASA/KSC and Air Force 30th Space Wing***
***Nine procedures in review and approval cycle - one procedure is hazardous (Lifting & Handling)***
*GSFC Safety and Range Safety have no issues with these procedures*
***Fueling Procedure***
***Has been trial-run by fueling contractor, Primex***
***Two procedures considered hazardous by NASA/KSC and Air Force 30th SW - Reviewed and Approved by Range Safety***
***Launch Procedures***
***Launch Procedures - Run and refined during each Launch Sim***
***Contingency Procedures - Ready to Go***
*Defueling, Launch Scrub, Battery Re-conditioning*
***Missile System Pre-Launch Safety Package (MSPSP)***
***Reviewed and Approved by Range Safety***

## Range Facilities (Communications)

***Range Facilities ****(Communications)*

***Communications Requirements straightforward - defined in Launch Site Support Plan (LSSP) and Operational Requirements Document (ORD)***
***Most Communications links rely on existing, previously used capabilities, except:  ***
***New S-Band Antenna at SLC-2 (installation / testing complete)***
***X-Band Splitter at 836 (checked out; installation/final testing week of 10/2/00)***
***New GPS Antennas at SLC-2 (checked out; installation/final testing week of 10/9/00)***
***Umbilical Rack Reset in Remote Launch Control Center: Boeing provides interface for Swales control box; installation/checkout week of 10/16/00***
***S-Band and S-Band links between 836 and SLC-2 must be shared by EO-1, SAC-C, and Delta; no unavoidable conflicts expected***

## Range Facilities (continued)

***Range Facilities ****(continued)*

***S/C GSE***
***All S/C EGSE remains at Astrotech, except:***
*Umbilical Rack:  Will be moved to SLC-2W EEB*
*Battery Racks:  Will be moved to SLC-2W Level 3*
*Chiller and Cold Plate: Will be moved to SLC-2W on S/C*
*FEDS, S-Band GSE, X-Band GSE, ASIST Work Stations, UPS’s: Will be moved to 836 Lab 1 GSE Area to support pad and launch activities*
***No GSE used at VAFB for first Time by EO-1, except:***
*Battery Cooling Cart: To be provided by NASA/KSC (Used by GGS/Polar); GSFC unit too large for use on Mobile Service Tower (MST).  If this A/C unit not available, one will be obtained by EO-1.*
***LV GSE***
***Work access platforms around S/C at SLC-2W to be provided by Boeing***

## Range Facilities (continued)

***Range Facilities ****(continued)*

***RCS GSE***
***Propellant Loading Cart has been demonstrated using PAC procedure IP-0645 ***
*Procedure approved by Range Safety*
***Pressure Test Console and all associated equipment has been calibrated and/or proof tested and will remain valid throughout the launch campaign***
***Portable Pressure Monitor Unit (PPMU) has been functionally demonstrated***
***All Export/ITAR issues associated with SAC-C propellant loading have been resolved***
***SCAPE/PHE and Interscan Training completed***
***Range Safety has reviewed GSE Design documented in the EO-1 MSPSP: SAI-SFTY-019 submitted to the Range 10/26/99***
*Approved by Range Safety*

## Launch Vehicle

***Launch Vehicle***

***Launch Vehicle Integration***
***Delta II / EO-1 Mission Specification***
*Currently being modified for November launch; no issues to date*
***Final Mass Properties -- completed; delivered to Boeing 9/13/00. No issues to date***
***Coupled Loads Analysis -- completed; all loads within design limits***
***Dynamic Clearance Analysis -- completed; significant margins***
***DPAF Design Certification Review -- DPAF Acoustic/Shock test levels do not impact EO-1 Acoustic/Shock environmental tests***
***Schedules -- Boeing’s Countdown Bar Charts and integrated ops schedule in good shape***

## Launch Vehicle

***Launch Vehicle***

***Launch Vehicle Interfaces***
***Payload Attach Fitting (PAF) provided by Boeing***
*Fit check with flight PAF successfully completed*
*100 lb springs instead of standard 200 lb springs needed due to EO-1 mass and CG off-set*
***T-0 Umbilical Harness***
*Flight harness mated during PAF fit check*
*Flight mate to be done as part of DPAF integration*
***Dual Payload Attach Fitting (DPAF)***
*First flight*
*Qual program and pathfinder complete*
***Two 24” Fairing Access Doors***
*GN**2 **purge line installation (Fly-away purge)*
*Battery cooling duct installation removal*
