Transportation

• Transportation Plan (SAI-PLAN-314) - 5/20/99
• Shipping Container
• Custom designed for EO-1 consists of dolly and
  cover
• Used for movement from Swales to GSFC dolly used
  for intra-facility movement in buildings 7/10/29
• Shock isolation system
• Desiccant, humidity indicator, pressure relief
  breather valves, through fitting for purging
• Spacecraft
• Bagged w/ GN2 purge in climate-controlled,
  air-ride van
• Swales mechanical personnel in chase vehicle
• Planned stops to monitor purge (oxygen sensor to
  be used prior to entry)
• Respond to contingencies
• Shock environment monitored

4
Transportation (continued)

• GSE
• Shipped 10 days prior to S/C in
  climate-controlled, air-ride van
• Responsibilities
• Swales
• Planning
• Loading of S/C into shipping container and onto
  truck
• Crating of loose equipment
• GSFC/Transportation Branch
• Arranging commercial transportation
• Installation of shock/vibration monitoring system
• Final preparation and loading of EGSE racks and
  crates
• NASA/KSC/Vandenburg Launch Site (VLS)
• Unloading support
• Storage of shipping container, crates, etc.
• Similar approach used for movement of S/C from
  Bldg. 836 to Bldg. 1610
• GSFC responsible for shipping flight battery and
  racks

Launch Site Processing - Overview

• Flow Similar to Many Previous GSFC Missions
• Launch Site Activities Plan (SAI-PLAN-337)
• Major Difference 1st Use of Boeing Dual Payload
  Attach Fitting (DPAF)
• Satellite
• Post-Ship Checkout in Bldg. 836
• Fueling DPAF Integration in Bldg. 1610 or
  Commercial Facility
• Launch from SLC-2W Co-manifested w/ SAC-C
  (Argentina)
• GSE
• Initially set up in 836
• Few items move to 1610 and SLC-2W
• Personnel
• Primary office space in 836
• Work at 1610/SLC-2W as necessary

Mission Level CDR RFA 26 (4.26)

• CDR RFA 26 Are safe/arm plugs required at the
  launch site?
• Response
• Red tag removal/installation items
• Ports, plugs, caps, hats, covers
• Removal/installation to be done as late as
  practical in launch site flow
• Safety
• RCS Enable Plug ONLY safety critical Item
• Installation of RCS Enable Plug maintains a
  minimum of 3 fault tolerance, per EWR 127-1,
  Range Safety Requirements
• Current plan to prevent/minimize risk of
  personnel injury and damage to hardware when in
  flight configuration
• S/C level procs have been modified to remove
  steps that could potentially damage any hardware
  or individual. These procs are being reviewed.
  Subsystem procs to be done
• Daily meetings will be held to review,
  coordinate, and be made aware of EO-1 and
  EO-1/SAC-C/Delta (Boeing) activities

Building 836

• Managed by NASA/KSC/VLS
• Class 100K Clean Tent
• Control Room for ASIST Work Stations and other
  EGSE
• Office area for EO-1 personnel
• Storage for shipping container, etc.

Bldg. 836 Lab 1 GSE Area
12
Building 1610

• Managed by NASA/KSC/VLS
• Class 100K Clean Room
• All SAC-C post-ship processing performed here
• Primex to fuel both spacecraft from single set-up
• DPAF and Vertical Shipping Container
  pre-positioned
• Only necessary personnel will work at 1610
  offices and most EGSE remains in 836
• NASA/KSC/VLS providing man-lift for S/C access
  once integrated w/ DPAF
• Potential availability issue this poses minimal
  impact to EO-1

13
Space Launch Complex 2 West

• Class 100K Clean Room on Levels 5 6
• Only necessary personnel will work at SLC-2W
  offices and most EGSE remains in 836
• All access and activities will be coordinated w/
  Boeing

14
EO-1 Launch Site Communications

• Comm Requirements Straightforward
• Integrated Operational Requirements Document
  issued by Boeing defines requirements to Western
  Range (WR)
• Most Comm Links rely on existing, previously used
  capabilities. Exceptions
• New S-Band Antenna at SLC-2 (installation/testing
  complete)
• X-Band Splitter at 836 (checked out final
  installation after IMAGE launch)
• New GPS Antennas at 836 and SLC-2 (checked out
  final installation after IMAGE launch)
• Umbilical Rack Reset in Remote Launch Control
  Center Boeing provides interface for Swales
  control box plan is to install/checkout after
  S/C arrival at VAFB
• 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

Planning / Procedure Status

• Goal is to utilize IT procedures to the maximum
  extent possible
• Fueling Procedure has been trial-run by fueling
  contractor, Primex
• Contingency Planning
• Defueling
• Launch Scrub
• Battery Re-conditioning
• Missile System Pre-launch Safety Package (MSPSP)
  status
• Initial package delivered to both 30th Space Wing
  and NASA/KSC/VLS
• Comments received
• GSFC Code 302 responding to these comments

GSE Status

• EO-1 requires relatively little GSE
• All EGSE remains in Bldg. 836, except
• Umbilical Rack Will be moved to SLC-2W
  Electrical Equipment Building (EEB) while S/C
  being fueled
• Battery Racks Will be used in Bldg. 1610 and on
  pad (located on Level 3)
• Chiller and Cold Plate Will be used in Bldg.
  1610 and on pad (located on S/C)
• No GSE used by EO-1 at VAFB for first Time by
  EO-1, except
• Battery Cooling Cart Being Provided by NASA/KSC
  (Used by GGS/Polar) GSFC unit too large for use
  on Mobile Service Tower (MST)

Launch Vehicle Integration

• Delta II/EO-1 Mission Specification
• Issued by Boeing in Dec.
• Currently being modified for Aug. launch
• No issues to date
