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

• IT Procedures
• Existing IT 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)

• 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)

• 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, UPSs 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

6
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 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 -- Boeings Countdown Bar Charts and
  integrated ops schedule in good shape

8
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
• GN2 purge line installation (Fly-away purge)
• Battery cooling duct installation removal
