ATDC Phased Development Overview

ATDC Phase 1

This Phase will develop a Liquid Oxygen (LO₂ ) Area (max capacity 56,000 gallons LO₂), containing the appropriate infrastructure to safely provide, control, distribute, test, and remove LO₂.  Supporting facility and GSE systems, such as a Gaseous Nitrogen (GN₂) purge capability, safety systems, instrumentation system, command and control system, closed-circuit cameras, and communications, will also be provided at this time.  At the end of Phase 1, the ATDC will be able to qualify LO₂ cryogenic components and will support the Shuttle Program by performing LOX Pump qualification testing.

Liquid Oxygen Area Infrastructure Provided:

• Cryogenic (LO2) Subsystem
  
• Pneumatic (GN2) Subsystem
  
• Instrumentation Subsystem
  
• Control Subsystem
  
• Camera Subsystem
  
• Communications Subsystem
  
• Facility Systems (e.g., Power, Grounding, Potable Water, Roads)
  
• Structures
  
• Safety Subsystems (e.g., Safing, Lightning Protection, Area Warning, Emergency Shower)

ATDC Phase 2

This Phase will develop a Liquid Hydrogen (LH₂ ) Area (max capacity 68,000 gallons LH₂), a Liquid Nitrogen (LN₂ ) Area (max capacity 28,000 gallons LN₂), and a Launch Mount.  As with the LO₂ Area, the appropriate supporting facility and GSE systems will be provided.  At the end of Phase 2, the ATDC will be able to qualify LH₂ and LN₂ cryogenic components and could support companies developing “2^nd Generation Vehicles” by being able to support cryogenic loading testing on company-provided simulators and equipment.

ATDC Phase 3

This Phase will develop a non-flight Test Demonstrator and its Park Site.  The Test Demonstrator will contain avionics, instrumentation and cryogenic tanks that can be loaded multiple times and used as a testbed to develop the next-generation cryogenic loading system.  A permanent capability to create Densified Cryogenics (LO₂ and LH₂) will be added during this Phase.  The instrumentation systems initially deployed in the LO₂ Area, LH₂ Area, LN₂ Area, and Launch Mount will receive augmentation.  At the end of Phase 3, the ATDC will facilitate research and development of umbilical systems, cryogenic loading concepts, and new instrumentation to provide more insightful information on system health and abnormal trending.

ATDC Phase 4

This Phase will extend existing High-Pressure GN₂ and Gaseous Helium (GHe) Pipelines to SLC 20, and add both a 2,000 sq. ft. Shop Facility, and a 5,000 sq. ft. Processing Facility.  The instrumentation, safety systems and infrastructure deployed during Phases 1 through 3 will be augmented and receive a  “Technology Refresh.”  The Test Demonstrator will grow in fidelity; avionics systems will be added to help develop new instrumentation to better understand the loading processes and leak isolation techniques.  A Checkout and Control System, deployed in the Processing Building, will provide new control software to lessen the workload of the operator.  At the end of Phase 4, the ATDC could support multiple research, development, test, and qualification activities, with a relatively quick reconfiguration time.

ATDC Phase 5

This Phase will expand the usage and capabilities of the ATDC to support emerging or commercially viable Spaceport Technologies.  Extensive market research to reevaluate spaceport technologies will be performed prior to this phase.  The ATDC will utilize “technology insertion” and feedback from both the market research and from operational analysis to selectively upgrade infrastructure deployed in earlier phases.  The Checkout and Control System, as well as the instrumentation, safety systems and infrastructure deployed during Phases 1 through 4will be augmented with a  “Technology Refresh.”  This Phase has been budgeted to reflect 30% of the total cost of the ATDC infrastructure deployed in Phases 1 through 4.  At the end of Phase 5, the ATDC will be a “world class” site for developing, testing and qualifying Spaceport Technologies.
