2Executive Summary Background
- Orbital Aggregation Space Infrastructure
Systems (OASIS) is an in-space architecture
concept consisting of highly reusable systems and
resources that provide a common infrastructure
for enabling a large class of space missions - FY01 RASC studies focused on preliminary design
of OASIS elements and analysis of Lunar Gateway
and commercial mission scenarios - This study package summarizes results of FY01
OASIS commercialization analyses - OASIS capability and potential commercial markets
(traffic model) - Economic viability analysis
- Preliminary costing of OASIS elements
Hybrid Propellant Module
Chemical Transfer Module
Solar Electric Propulsion Stage
Crew Transfer Vehicle
3Executive SummaryResults
- OASIS Commercial Traffic Models
- OASIS performance has been evaluated for
commercial satellite applications - OASIS commercial traffic models have been
developed based on satellite delivery considered
the floor for potential commercial
applications - Future DoD missions may provide additional OASIS
applications/usage rates - OASIS Economic Viability
- HPM/CTM has commercial potential when used as an
orbital transfer stage in conjunction with alow
cost booster to LEO at flight rates greater than
3 per year per HPM/CTM - OASIS commercial viability is highly sensitive to
infrastructure costs, mission rates and
Earth-to-LEO launch costs

- Assess OASIS applicability and benefits for
Earth Neighborhood commercial and DoD space
missions in the 2015 timeframe - Determine key needs for projected commercial/DoD
missions that OASIS may support (e.g.,
deployment, refueling/servicing,
retrieval/disposal) - Quantify levels of potential commercial
utilization and develop ROM estimates for
economic impacts - Study Drivers
- Projected commercial/DoD satellite market
- OASIS design (sizing, performance)
- OASIS allocation to support identified markets
(traffic models) - ETO transportation costs (trades vs. non-OASIS
architectures, cost of resupply propellant) - Assumptions
- Scenarios utilize OASIS elements defined for
Exploration missions using performance masses - A low cost Earth-to-LEO transportation capability
is required - Highly reliable RLV or ELV for sensitive cargo
- Lower cost LEO delivery system for propellant
resupply - Industry adopts common infrastructure (e.g.,
attach fittings, refueling ports, plug-and-play
avionics) - Goal - Maximize potential commercial
opportunities (i.e., Greatest number of
satellites deployed/serviced with minimum number
of OASIS elements)

proximity operations and docking, reboost in
storage orbits, etc) - CTM

locally optimal orbit locations - Perigee and Apogee (i.e., Hohmann transfers) for
altitude variation - Node crossings for inclination changes
- Nodal complement locations for right ascension
changes - Propellant is available to autonomously
pre-position to HPM rendezvous point as necessary - SEP

duration impact and refurbishment costs - Satellite

ISS inclination - Requires one constellation of 10 HPM/CTMs near
polar inclination - Planar launch window opportunities within 30

Traffic Model
24OASIS Integrated Traffic Model
Traffic model variation is based on satellite
lifetime extremes
Lifetime Estimates 5 years 10
years
- Refined commercial traffic model based on
- Higher usage rate missions only (gt 3 flights per
HPM per year) - Single launch site from ETR to eliminate
duplication of ground infrastructure (excludes
polar servicing) - 50 market share (of high traffic model)
25Commercialization Study OASIS Economic
Viability Analysis
26OASIS Economic Viability Analysis Overview
- Objective
- Provide a preliminary economic viability
assessment of HPM/CTM in future commercial
satellite deployment/servicing markets as defined
by the integrated traffic model - Approach
- Compare potential life cycle earnings over range
of critical economic factors - Identify economic factors with strong influence
on earnings - Determine the economic sensitivity and establish
hurdle values for these critical factors - Earning levels necessary for economic viability
include allowance for non-recurring start up
costs - Start up costs per HPM/CTM include HPM/CTM
procurement (ROM estimate 150 million each),
and initial launch, development and deployment of
commercial peculiar infrastructure (e.g., HPM
propellant processing facilities) - Start up costs per HPM/CTM assumed not to exceed
500 million actual value varies inversely with
fleet size - Industry leverages government investment in
infrastructure development
27Identification of Critical Economic Factors
- Critical Economic Factors
- Charge to deploy satellite to operational orbit
- Propellant delivery cost to LEO ( per kg)
- Payload (satellite) cost ( per kg) to LEO
- HPM/CTM use rate
- Life cycle earnings
- Definition
- Total charge to customer to deploy their
satellite - Establishes cost to resupply HPM with full load
(32,000 kg) of propellant per deployment - 5,000 kg payload, calculated at twice the /kg
as propellant - HPM/CTM flights per year (based on traffic model
analysis) - LCE Ch - (Prop P/L)R10 year HPM/CTM life
