      Reusable Launch Vehicle (RLV) Advanced Technology
                   Demonstrator :  X - 33

The  National Space Transportation Policy charters  NASA  to
lead  the technology development and demonstration  of  next
generation  reusable space transportation  systems,  and  to
focus the research on technologies to support a decision  no
later  than December 1996 to proceed with a sub-scale flight
demonstration which would prove the concept of single-stage-

The   objective   of  NASA's  technology   development   and
demonstration  effort is to support government  and  private
sector decisions by the end of this decade on development of
an  operational next-generation reusable launch system.   It
is   envisioned  that  the  private  sector  could  have   a
significant role in managing the development  and  operation
of a new reusable space transportation system.

The  objective  of  this NASA Cooperative  Agreement  Notice
(CAN)  is  to  initiate  concept  definition/design   of   a
technology  demonstrator  vehicle,  X-33,  followed  by  the
design/demonstration  of competitively selected  concept(s).
The  X-33  must  adequately demonstrate the key  design  and
operational aspects of a reusable space launch system so  as
to  reduce the risk to the private sector in developing such
a commercially viable launch system.

Significantly lowering the cost of space launch  for  medium
class  payloads will promote U. S. economic growth,  improve
the  quality  of  life,  and contribute  to  the  continuing
economic development of near-earth space.

It  is  the  government's  intent  to  demonstrate  critical
elements of a future
Single-Stage-To-Orbit (SSTO) rocket powered RLV.   The  X-33
will  be  an integrated systems testbed for advanced  launch
technologies applicable to a next generation RLV.   NASA  is
coordinating  program implementation with the Department  of
Defense (DoD).

NASA  is  initiating  a  progressive  competition  with  the
issuance of  this CAN.  This CAN solicits proposals, for the
total  X-33  effort, that offer a new way of doing  business
consistent with space policy.  Initial proposals in response
to  this  CAN  should  reflect creative business  investment
strategies  and  planning,   and  technical  solutions  that
address  programmatic and technical challenges  involved  in
the   Concept   Definition/Design  Phase  (Phase   I);   the
Design/Demonstration  Phase (Phase II)  and  the  commercial
RLV   Development/Operation  Phase   (Phase   III).    These
proposals  should  be specific/detailed for  Phase  I,   and
reflect  preliminary   plans  for  both  of  the  subsequent
phases. At the end of Phase I, proposals are planned  to  be
received for Phase II, and competitive selection(s) made.

The  performance  period  of Phase  I  is  approximately  13
months.   Phase II, which includes design, build and  flight
demonstration of the X-33, will be initiated by the  end  of
FY  1996 and will continue through CY 1999.   Phase III will
be  implemented  following  government  and  private  sector
decisions  by  the end of this decade on development  of  an
operational next generation reusable launch system.

Multiple  awards are planned for the X-33 Phase  I  activity
during which each participant shall mature their total  X-33
business  investment  strategies  and  planning,  operations
planning  and  vehicle  design  and  analysis   with  detail
sufficient  to  permit   competitive selection  of  industry
partner(s)  and their X-33 design concept(s) at the  end  of
the  period.  Selection to proceed into Phase II, the period
to  fabricate and flight test X-33 concept(s), will occur as
a result of evaluation of proposals reflecting the following
general evaluation criteria:  mature business management and
cost   arrangements/planning,  design  maturity,   technical
content/approach;    more    specifically:    1)    detailed
cost/business    investment   strategies,    planning    and
arrangements for  Phase II,  as well as preliminary business
planning,  strategy and linkage to Phase  III,  2)  detailed
operations  planning  for Phase II as  well  as  preliminary
operations  planning for and linkage to Phase  III   and  3)
detailed  planning for  vehicle design and  analysis  to  be
demonstrated  in  Phase  II as well  as  preliminary  design
planning for and linkage to Phase III.

Consistent with the above, the government reserves the right
to  provide more specific evaluation criteria for  selection
for Phase II activity prior to receipt of Phase II proposals
for evaluation.

Proposals  requiring  restrictions on  distribution  of  any
aspect of the completed effort and resulting technology must
include  a  justification for the restriction and  the  time
period  for  which  the  restriction  would  apply.   It  is
important  that  technology demonstrated  from   cooperative
agreements  resulting  from this CAN reside  in  the  public
domain.   Excessive use of restrictions on  distribution  of
the  subject technology could result in nonselection of  the

Proposers should also highlight the offeror's experience and
capabilities in proposed areas and how the experience and
capabilities would be employed in support of this technology
demonstration activity.

Participation  in this program is open to all categories  of
organizations,  both  domestic and  foreign.   Organizations
include   industry,   educational  institutions,   nonprofit
organizations, NASA centers, and Federal, state,  and  local
government  agencies.  Guidelines for foreign  participation
are  given  in Appendix A, Section 8.  Joint proposals  that
demonstrate  effective, mutually beneficial partnerships  or
cooperative  arrangements between government, academia,  and
industry  are encouraged.  U.S. Federal Government  agencies
who wish to participate will be expected to supply their own

Proposers shall submit proposals by January 6, 1995.  Black-
out  conditions  will exist upon receipt  of  proposals  for
evaluation.   Proposals  will be evaluated  by  peer  and/or
technical review committees.

Offeror's  initial  proposals  for  Phase  I,  X-33  Concept
Definition/Design  Phase(includes preliminary  planning  for
all   subsequent   phases),  shall   include   cost/business
investment strategies and planning, operations planning  and
vehicle  design and analysis.  Offerors may  elect  to  also
propose supporting technology demonstration efforts.   Areas
to  be  accomplished  in Phase I are  further  described  in
paragraph 4.0, Appendix A.

All  or  part of a proposal may be selected for negotiations
leading  to  a  possible  award of a  cooperative  agreement
unless  the offeror requests otherwise.  A proposal that  is
technically  and  programmatically  meritorious,  but   that
cannot be accepted because of funding uncertainties, may  be
retained for future consideration, should additional funding
become  available,  unless the offeror  requests  otherwise.
Evaluation, selection and award may occur during the  period
of time from receipt of proposals for evaluation to one year
after issuance date of this CAN.

1.0   Introduction

The  objective  of  this NASA Cooperative  Agreement  Notice
(CAN)  is  to  initiate the concept definition/design  of  a
technology  demonstrator vehicle, Experimental-Thirty  Three
(X-33),   followed  by  the  design/demonstration   of   the
competitively selected concept(s), for technologies required
for a low cost next generation reusable space launch system.
The  X-33  must  adequately demonstrate the key  design  and
operational aspects of a Single Stage to Orbit (SSTO) rocket
system  so  as to reduce the risk to the private  sector  in
developing such  a commercially viable launch system.

Significantly lowering the cost of space launch  for  medium
class  payloads  will promote U.S. economic growth,  improve
the  quality  of  life,  and contribute  to  the  continuing
economic  development of near-earth space.  The lowering  of
the cost of space launch is a goal of NASA and the Office of
Space Access and Technology.

The  NASA  Office  of  Space Access and Technology  conducts
space  research  and  development  through  sponsorship   of
technology programs conducted at the NASA Field Centers,  in
United  States  industry, and in American universities.  The
Space  Transportation Division supports the Office of  Space
Access  and TechnologyOs goals by sponsoring the development
of   next   generation   Reusable   Launch   Vehicle   (RLV)
technologies.    NASAOs   Space  Transportation   technology
program  will accelerate the development and application  of
new  space  launch technologies and operational concepts  to
meet NASAOs science and engineering goals and contribute  to
the  continuing  development of the  national  space  launch
industry.  The  goal of the RLV technology  program  is  the
continued lowering of the cost of access to space to promote
the  creation and delivery of new space services  and  other
activities  that  will improve economic competitiveness  and
benefit all citizens.

1.1  Background

The  Government  has  numerous requirements  for  economical
orbital  RLV's.   Demonstration of critical issues  such  as
operability,  supportability,  and  cost  are  crucial    to
successful  commercial development and operation  of  future
RLV's.   Preliminary assessments indicate that a significant
payoff  can  be  achieved by applying  near  term,  advanced
technologies  to  a reusable, Single Stage to  Orbit  (SSTO)
rocket  due  to significantly reduced servicing, integration
and  operating  costs.  This and future phases  of  the  RLV
program are structured as follows:

1.2  X-33 Concept Definition/Design Phase  (Phase I)

This   phase   will  consist  of  concept   definition   and
preliminary  design  of  a  single stage  reusable  advanced
technology demonstrator system, designated the X-33.  The X-
33  system  includes the flight vehicle,  supporting  ground
based technology demonstrations, and any required ground and
flight  support systems. The X-33 will demonstrate the  same
structural  approach, materials, and unit  weights  required
for  an  SSTO  rocket vehicle.  The X-33 ground support  and
flight  control  systems  will  be  designed  to  accomplish
operations and supportability goals which are key  to  lower
cost system operations.  Based on the results of this phase,
an  industry/concept  team will be selected  for  Phase  II.
This CAN is a solicitation for this phase.

1.3  X-33 Design/Demonstration Phase  (Phase II)

This  phase  will consist of the final design,  fabrication,
assembly and test of the X-33 System.  The X-33 vehicle will
be flight tested, using a flight envelope expansion process,
to  demonstrate  aircraft like operations.   Flight  testing
will be accomplished at an appropriate test range.

1.4   Commercial   RLV Development/Operation  Phase   (Phase

The  previous  two phases are focused towards  demonstrating
the  technology  to  build  reusable  launch  vehicles  with
aircraft-like  operations.  If fully successful,  they  will
enable  a  low  risk, low cost development of a commercially
operated  RLV  system.  This phase will design, manufacture,
and  operate  the  RLV  system.   The  level  of  government
participation in this phase will be minimized.

2.0  Scope

This  program will implement the recently released  National
Space  Transportation  Policy,  specifically  Section   III,
paragraph  2(b): "Research shall be focused on  technologies
to support a decision no later than December 1996 to proceed
with a sub-scale flight demonstration which would prove  the
concept   of   single-stage  to  orbit."   The   X-33   will
demonstrate  the  critical technologies needed  for  orbital
SSTO rockets in realistic operational environments.  To  the
extent practical, the X-33 will be tested in the ascent  and
reentry flight environments of a full-scale SSTO rocket.  In
addition,  the  X-33 will focus on those operational  issues
which  are critical to the development of reliable low  cost
reusable  space  transportation.  The X-33 will  incorporate
more  advanced  materials with unit  and  component  weights
equivalent  to  those required by a follow-on  SSTO  rocket.
The  performance demonstrated by the X-33 will  provide  the
necessary  data  to establish the detailed requirements  for
future operational RLV's.

3.0  Objectives and Guidelines

3.1  Technical Objectives

The  following are provided as a set of technical objectives
to  be  accomplished  by the X-33 and follow-on  RLV  launch
systems.  Offerors must accomplish, at a minimum, objectives
reflected in Table 1.  Accomplishment of effort beyond  that
reflected  in the table as minimally required,  is  possible
but   must   be  accomplished  within  established   funding
guidelines.  These are consistent with the October  6,  1994
Draft of the National Spacelift Requirements Document.   For
the   follow-on  operational  system  (RLV),  the  following
objectives  should be used for initial design  purposes  and
are subject to later trade.

designed  and  tested  so  as to ensure  their  traceability
(technology  and general design similarity) and  scalability
(directly  scalable unit weights, loads, design, fabrication
methods, and testing approaches) to a full scale SSTO rocket

3.3  Operability Guidelines

The  following  should be used as guidelines when  designing
both the X-33 and RLV systems:

        The  vehicle  should feature a  minimal  number  of
       separate systems and subsystems.  The vehicle  should
       minimize  the number of active components  needed  to
       accomplish its mission safely.
        The  vehicle should minimize the number of hands-on
       activities  needed  to  handle,  maintain,  checkout,
       service,     and    launch.     Vehicle    servicing,
       maintenance, and operations should be designed to  be
       accomplished  with  a  minimal number  of  personnel.
       Avionics  should maximize the use of  built  in  test
       and evaluation.
        The vehicle should minimize the number of different
       The vehicle should minimize hazardous operations.
       The vehicle should minimize the number of man-hours,
       special tools, and support equipment needed to  turn-
       around and refly the vehicle.
        The  number  of  closed compartments  and  required
       purges  should  be  minimized.  Actively  conditioned
       components  should be  minimized or eliminated  where
        The mean time between major overhaul for the system
       and components should be maximized.
        Component accessibility should be maximized,  using
       aircraft standards where possible and relevant.
        The  number of criticality-one failure modes should
       be minimized.
         Robust   design  margins  should  be  used   where

4.0  Areas to Be Accomplished in Phase I

The  general  areas  to be accomplished in  Phase  I  should
include, but not be limited to the following:

4.1  Business Planning

Business  investment strategies and planning for   the  X-33
design/demonstration  (Phase II) and  follow-on  RLV  (Phase
III)  will  be initiated and matured during Phase  I.   This
will  determine  the  requirements for the  development  and
operation  of  a cost-effective, commercially developed  and
operated  RLV system.  Planning should include, but  not  be
limited to:

    Cost  /  benefit  modeling (inc. cash, revenue  stream,
     depreciation, interest, taxation, etc.).
    Potential    financial    investment    sources     and
    Level  of  government participation in RLV  development
     and operations.
    -   Legislation  required to permit unique government  /
     industry partnerships.
    Cost  and schedule to develop, manufacture, and operate
     flight and related support systems.
    -   Comprehensive to a level that will permit  credible,
     independent assessments.
    Potential   commercial  market  share  with  associated
     requirements to achieve.
    Potential and required return on investment (focused on
     long term).

    Management approach.

4.2  System Operations Planning

The   X-33   will  demonstrate  key  operational  attributes
required  for  a cost effective SSTO rocket  system.   As  a
minimum, the following will be accomplished in the design of
the X-33:

        Flow down of SSTO rocket operations requirements to
       the X-33 (i.e., traceability).
       Reliability, maintainability, and supportability.
       Operation of ground support systems.
       Flight operations.
       Logistical support.
       Manpower, skill types and levels.
        Estimated  vehicle turnaround,  mean  time  between
       failure, mean time to repair, reliability, and  other
       critical maintenance parameters.
         Operations  and  maintenance  cost  estimates   to
       accomplish the flight requirements.
        Overall  support concept including  flight  vehicle
       support,  propellant  storage, and  range  facilities
       and services.
       Transportation concept.

4.3  Vehicle Design and Analysis

4.3.1     Technical Baselines

For  both  the  X-33  and follow-on SSTO  rocket  system,  a
technical   baseline   with  the  following   representative
parameters, at a minimum, shall be defined:

        Physical design, layout, materials, dimensions, and
        Description of acoustic, vibration, thermal  (e.g.,
       aeroheating,  base  heating,  etc.),  and  structural
       loads   (e.g.,  loads  along  vehicle   station)   on
        Flight  vehicle  mass  properties  including  gross
       liftoff  weight,   empty weight,  unit  weights,  and
       mass fractions.
       Flight performance, aerodynamic characteristics, and
       optimized ascent and descent trajectories.
        Flight  vehicle stability and guidance, navigation,
       and   control   assessment  and  incorporation   into
       vehicle design.
        Payload  capacity versus maximum velocity,  orbital
       inclination, and altitude capability achieved.
        Identify total lift margin including both  payload,
       design  weight  margins  and any  performance  weight
       margin above the minimum necessary to achieve a  once
       around the earth mission for the orbital vehicle.
       Propulsion subsystem characteristics.
       Cross range maneuver capability.
       Crosswind takeoff and landing limitations.
       Weather constraints.
       Operations (see section 4.2).
        Payload  and  crew  accommodations  and  processing
       (where applicable).

4.3.2     SSTO Rocket Concept Definition

An  SSTO  rocket  vehicle  concept  shall  be  designed  and
analyzed  at  a level sufficient to demonstrate SSTO  rocket
requirements flowdown to the X-33 flight system.  The  areas
addressed  should  be similar to those  described  below  in
section 4.3.3.

4.3.3     X-33 Preliminary Design


     The  X-33  system  design will make use  of  near  term
     available technologies and innovative concepts  in  the
     vehicle  design, manufacturing processes, assembly  and
     integration  process, and ground  test.   Designs  will
     focus on operational simplicity and  minimizing vehicle
     processing  requirements.  Detailed layout and  systems
     engineering   analysis  required  to  demonstrate   the
     feasibility and performance of the X-33 vehicle will be
     provided.   The  level  of  design  required  will   be
     sufficient  to  permit a concept downselection  at  the
     conclusion of this phase.

     As a minimum, the scalability and traceability of the X-
     33  airframe,  cryogenic tanks and  thermal  protection
     systems (TPS) to the SSTO rocket will be identified  in
     order  to  establish that the required structural  mass
     fraction of the SSTO rocket is achievable. Where the X-
     33  design is not directly traceable to the full  scale
     SSTO   rocket,   product  enhancements,   ground   test
     programs, or alternative minimal risk design approaches
     to   provide   an  SSTO  rocket  capability   will   be


     The  X-33  design shall be developed using a design-to-
     cost  methodology. The goal shall be to  constrain  the
     total X-33 program cost as close to a $(To Be Proposed)
     program  or lower as possible, however, all costs  must
     be completely credible, realistic, and defendable to an
     independent  costing evaluation.  Total  costs  include
     both government and industry investments combined.


     A comprehensive test program shall be developed for the
     X-33, identifying the configuration and number of  test
     articles, a description of the test facilities,  and  a
     schedule  for  the  test program.   This  will  include
     testing  for  both  ground and  flight  components  and


     The  software structure needed to meet the X-33  system
     requirements  will  be  defined and  will  include  the
     development program for generating the necessary  code,
     software  tools,  and  validation  procedures   to   be


     A  preliminary design of X-33 support equipment will be
     prepared,  including  an  integrated  program  for  the
     manufacture,  test, and integration of  this  equipment
     with   the  flight  vehicle.  Support  equipment  shall
     include  factory  assets  needed  to  manufacture   and
     assemble the X-33, test stands needed to validate the X-
     33  prior  to flight, propellant storage and  servicing
     equipment,  maintenance equipment, and other operations
     support requirements.


     Potential   problem  areas  critical  to   engineering,
     operability,   technology,  reliability,   safety,   or
     schedule will be analyzed.  For the identified critical
     risk  areas,  a  program to reduce the  risks  will  be
     established.    Appropriate    technical    performance
     measurements  for  program critical  elements  will  be


     The  X-33 component procurements (including appropriate
     descriptions,   e.g.,  fabricate  vs.  off-the   shelf,
     schedule,   etc.)  required  to  achieve  the   program
     schedule and contain program costs shall be identified.

4.3.4     Phase II Supporting Technology Demonstrations

The   identification  of  Phase  II  supporting   technology
demonstrations required to develop critical technologies for
SSTO rockets - not incorporated on the X-33 flight vehicle -
and  the  development  of  a plan (tasks,  rationale,  cost,
schedule, facilities, etc.) for their  accomplishment during
Phase  II shall be finalized during Phase I.  Funding levels
for  these demonstrations are included in the RLV Technology
line item (Phase II) in Section 6.0.

4.4  Phase I Supporting Technology Demonstrations

In  addition to the above description of Phase I  activities
to   be  accomplished,  early  technology  hardware/software
demonstrations to be implemented during Phase I (i.e.,  X-33
Concept Definition/Design Phase) may be pursued if  selected
offeror  elected to propose this activity.  These technology
demonstrations   must  be  focused  on  those   technologies
required  to  achieve a successful X-33 flight demonstration
program  (and follow on RLV), must not be currently  in-work
under  existing  efforts (e.g., Advanced  Launch  Technology
NASA  Research Announcements), and must be completed  at  or
before  the  end  of  Phase  I.  Funding  levels  for  these
demonstrations are included in the RLV Technology line  item
(Phase I) in Section 6.0.

These demonstrations may be related, but are not limited  to
the following generic technologies:

                         APPENDIX B


.c2.1.    Foreword

NASA  depends  upon industry, educational institutions,  and
other  nonprofit organizations for many of its research  and
development efforts. While a number of mechanisms have  been
developed  over  the  years  to  inform  the  research   and
development  community  of those areas  in  which  NASA  has
special   research  interests,  the  instructions  in   this
appendix apply only to this Cooperative Agreement Notice.  A
NASA  Cooperative Agreement Notice (CAN) permits competitive
selection  of  projects  in  accordance  with  statute,  and
preserves some of the traditional concepts and understanding
associated  with NASA sponsorship normally  solicited  by  a
NASA Research Announcement (NRA). A CAN also introduces  new
concepts for NASA sponsorship.

.c2.2.    Policy

  a. NASA fosters and encourages the submission of proposals
relevant  to  Agency mission requirements  by  solicitations
which describe areas of interest to NASA. Proposals received
in  response  to  this CAN will be used only for  evaluation

   b.  NASA does not allow a proposal, the contents of which
are  not  available without restriction from another source,
or  any unique ideas submitted in response to the CAN, to be
used  as the basis of a solicitation or in negotiation  with
other  organizations, nor is a pre-award synopsis  published
for individual proposals.

   c.  A  solicited proposal that results in  a  NASA  award
becomes  part of the record of that transaction and  may  be
available  to  the  public  on specific  requests;  however,
information or materials that NASA and the awardees mutually
agree  to  be  of  a  privileged  nature  will  be  held  in
confidence  to  the extent permitted by law,  including  the
Freedom of Information Act.

    d.  NASA  may  select  only  a  portion  of  a  proposed
application,  in which case the proposer will be  given  the
opportunity to accept or decline such partial acceptance.

   e. NASA reserves the right to reject any or all proposals
received  in  response  to  the  CAN  when  such  action  is
considered in the best interest of the Government.

.c2.3.    Relationship to Award

A  cooperative  agreement will be  used  to  accomplish  the
effort  funded  on  the  basis of a  proposal  submitted  in
response to this CAN.

.c2.4.    Conformance to Guidance

   a.  NASA does not have any mandatory forms or formats for
preparation  of responses to CANs; however, it is  requested
that  proposals  conform  to the procedural  and  submission
guidelines  covered  in  these  instructions,  as  well   as
Appendix  C, CAN proposal format.   In particular, NASA  may
accept proposals without discussion; hence, proposals should
initially be as complete as possible and be submitted on the
proposersO most favorable terms.

    b.   In  order  to  be  considered  responsive  to   the
solicitation,  a  submission must, at a minimum,  present  a
specific  project  within the area delineated  by  the  CAN;
contain sufficient technical and cost information to  permit
a meaningful evaluation; be signed by an official authorized
to  legally  bind  the submitting organization;  not  merely
offer  to  perform  standard services  or  to  just  provide
facilities  or services; and not significantly  duplicate  a
more specific, current, or pending NASA solicitation.

.c2.5.    CAN-Specific Items

   a. Cooperative agreements require substantial involvement
by  NASA  in  performance of the work under  the  agreement.
This use of NASA Center resources must be negotiated between
the  proposer  and  the  effected NASA  Center(s)  prior  to
submission  of  the  proposal and must be  verified  with  a
letter   of  commitment  signed  by  the  respective  Center
Director, or his designee.  Proposers may make use  of  more
than  one  NASA  Center.  This letter  of  commitment  shall
indicate the resources contributed; including direct  labor,
facility  usage, other NASA supplied equipment and services,
and  direct  program charges related to the  performance  of
NASA  responsibilities specified in the proposal; and  shall
be included in the standard prefatory material.

   b. Any non-NASA resources included in the proposed effort
costs  shall be verified with a letter of commitment  signed
by   an   authorized   representative  of   the   resourceOs
organization(s).  This letter of commitment  shall  indicate
the resources contributed with any conditions concerning the
use of these resources and shall be included in the standard
prefatory material.

.c2.6.    Proposal Contents

   a.  The  following general information is needed  in  all
proposals  in order to permit consideration in an  objective
manner.   Each  proposal  copy shall contain  all  submitted
material, including a copy of the transmittal letter  if  it
contains substantive information.

   b.  The  proposals shall have fully completed and  signed
cover  pages  and certifications, in accordance  with  those
given in Appendix C of this CAN.

   c.  Proposals  are  expected to be written  concisely  in
English  to  minimize  the burden on the  reviewers  and  to
facilitate the overall evaluation process.  The total length
of  the  proposal including cover page, prefatory  material,
figures, tables, list of references, etc., shall not  exceed
100  sheets of 8.5O x 11O paper, with a maximum of 52  lines
per page (point size 12 or larger, with 1-inch margins).

Proposals  using  type  smaller than 12  points,  compressed
type,  or  less-than-normal leading (space  between  lines),
which makes reading difficult may be returned unreviewed.

Review  panels will schedule reviews based on 75  pages  per
proposal.   Proposals longer than 75 pages may  be  returned

To  facilitate  the  recycling of shredded  proposals  after
review,  proposals shall be submitted on plain, white  paper
only.   This  precludes the use of cardboard stock,  plastic
covers, and colored paper.

  d. Transmittal Letter or Prefatory Material

     (1)  The legal name and address of the organization and
     specific division or campus identification, if part  of
     a larger organization;

     (2)   A  brief project title intelligible to a literate
     reader and suitable for use in the public press;

     (3)   Type  of  organization; e.g., profit,  nonprofit,
     educational,  small  business,  minority,  women-owned,

     (4)   Name and telephone number of the Lead Partner and
     business   personnel  who  may  be   contacted   during
     evaluation or negotiation;

     (5)  Identification of any other organizations that are
     currently evaluating a proposal for the same effort;

     (6)   Identification of the specific CAN, by number and
     title, to which the proposal is responding;

     (7)   Dollar amount requested of NASA, desired starting
     date, and duration of project;

     (8)  Date of submission; and

     (9)   Signature of a responsible official or authorized
     representative of the organization, or any other person
     authorized to legally bind the organization (unless the
     signature appears on the proposal itself).

     (10) Letters of commitment.

  e. Restriction on Use and Disclosure of Proposal

It  is NASA policy to use information contained in proposals
for  evaluation  purposes only. While this policy  does  not
require   that  the  proposal  bear  a  restrictive  notice,
offerors  or quoters should, in order to maximize protection
of  trade secrets or other information that is commercial or
financial,  and  confidential  or  privileged,   place   the
following  notice  on  the title page of  the  proposal  and
specify  the information subject to the notice by  inserting
appropriate  identification, such as page  numbers,  in  the
notice.  In  any  event,  information  (data)  contained  in
proposals will be protected to the extent permitted by  law;
but, NASA assumes no liability for use and/or disclosure  of
information not made subject to the notice.


              Restriction on Use and Disclosure

  h. Project Description

     (1)   Initial proposals in response to this  CAN  shall
     reflect   specific/detail   plans   for   the   Concept
     Definition/Design Phase of the X-33,  with  preliminary
     plans    for    both   the   follow-on    period    for
     Design/Demonstration  and  for   the   commercial   RLV
     Development/Operation Phase. The initial proposal shall
     contain    for   each   phase,   sections   addressing:
     1)Technical,   2)  Management,  and  3)  Cost.    These
     proposals shall reflect planning for all phases of  the
     X-33 which include the following for each phase, in the
     following priority:

      -  Business Investment Strategies and Cost Planning
      -  Operations Planning
      -  Vehicle Design and Analysis

     Additionally, offerors may or may not elect to  include
     in  their  initial proposal for the Phase  I  activity,
     supporting technology demonstration efforts.

     Initial  proposals  must  not,  however,  include  only
     supporting  technology demonstration  efforts,  without
     proposing  to  accomplish  in  parallel  the  Phase   I
     activity as discussed above.

     (2)  The technical section for each phase shall contain
     a  brief  summary,  followed by a  description  of  the
     technical content of the proposed effort, the approach,
     and  the  expected results. Proposals shall  include  a
     brief   schedule   for   the  proposed   effort,   with
     milestones, payment milestones, and completion dates.

     (3)  The  proposals  shall reflect a detailed statement
     of   the   work   to  be  undertaken  for  the  Concept
     Definition/Design  Phase  and  shall  include  specific
     milestone  accomplishments planned, payment  milestones
     and completion dates; specific technical objectives and
     expected significance; relation to the present state of
     the  art;  and relation to previous work  done  by  the
     proposer and to related work in progress elsewhere. The
     statement  should  outline the general  plan  of  work,
     including   the   proposed   business   plan/management
     arrangements  and an adequate description  of  proposed
     NASA  Center or DoD Laboratory/Center involvement based
     upon  prior  coordination/discussions  with  respective
     Center  involved.  The  project description  should  be
     prepared  in  a  manner that addresses  the  evaluation
     factors   in  these  instructions  and  any  additional
     specific   factors   in   the  CAN.   Any   substantial
     collaboration  with  organizations or  individuals  not
     referred to in the budget or use of consultants  should
     be described.

     (4)   The  proposals  shall reflect  detailed  business
     investment  strategies and planning  to  be  undertaken
     during  the Concept Definition/Design Phase  and  shall
     describe the evolutionary path/linkage proposed  to  be
     followed  during  each subsequent phase  of  the  X-33,
     including the commercial Development/Operation Phase.

  i. Management Approach

     (1)    For    efforts   involving  interactions   among
     individuals   from  more than one  organization,  plans
     for dissemination of responsibilities and any necessary
     arrangements  for ensuring a coordinated effort  should
     be described.  This shall include a one page outline of
     the    articles   of   collaboration.    The    working
     relationship   with  NASA  field  centers   should   be
     described in this section.

     (2)   The  initial  proposals should reflect   detailed
     management  planning, structure and approach   for  the
     Concept   Definition/Design   Phase   of   the    X-33.
     Additionally,  preliminary planning for  management  of
     the  Design/Demonstration Phase should be  included  as
     well  as  linkage to the planned management during  the
     commercial Development/Operation Phase.

  j. Key Personnel

     (1)   A  brief biographical sketch referencing  related
     work of key personnel shall be included, along with any
     exceptional qualifications covering the past  5  years.
     The  biographical sketch shall not exceed one page  per

     (2)   The  Program  Manager is responsible  for  direct
     supervision of the work and participates in the conduct
     of   the   project   regardless  of  whether   or   not
     compensation is received under the award.  Omit  social
     security number and other personal items which  do  not
     merit consideration in evaluation of the proposal. Give
     similar   biographical  information  on  other   senior
     professional personnel who will be directly  associated
     with  the  project. Give the names and  titles  of  any
     other  engineers  and  technical  personnel  associated
     substantially with the project in an advisory capacity.
     Universities  should  list the  approximate  number  of
     students or other assistants, together with information
     as  to  their level of academic attainment. Any special
     industry-university cooperative arrangements should  be

  k. Facilities and Equipment

     (1)   Proposals should describe the proposed use of any
     NASA facilities and equipment during the conduct of the
     proposed  cooperative agreement.  This should be  based
     on  prior  discussions concluded  with  the  respective
     center  to  agree on potential government contributions
     in  a  resultant  cooperative  agreement.   Should  the
     potential government contribution involve use of  Civil
     Service  personnel,  the proposal  must  reflect  costs
     associated with those personnel.

     (2)   Describe available facilities and major items  of
     equipment especially adapted or suited to the  proposed
     project,  and any additional major equipment that  will
     be  required. Identify any Government-owned facilities,
     industrial plant equipment, or special tooling that are
     proposed for use on the project.

     (3)    Before  requesting  a  major  item  of   capital
     equipment, the proposer should determine if sharing  or
     loan of equipment already within the organization is  a
     feasible   alternative   to   purchase.   Where    such
     arrangements  cannot be made, the  proposal  should  so

     (4)    Potential  respondents  should  be  aware   that
     regulations require that NASA retain ownership  of  all
     equipment  purchased  with NASA's contribution  to  any
     cooperative agreements.

  l. Proposed Costs/Cost Sharing

In  addition  to the instructions contained here,  proposers
are  referred to AppendixEC.  This appendix contains a model
format for proposed budgets.

     (1)    Cost   sharing  is  required  under  cooperative
     agreements     with     "for-profit"     organizations.
     Significant  cost sharing by industry  is  anticipated.
     Cost sharing may include cash (including IR&D) and  in-
     kind contributions in accordance with section 23 of OMB
     Circular  A-110, which is provided as   Appendix  G  to
     this CAN.  Proposers shall provide rationale to support
     the cost sharing amounts proposed and state that it  is
     consistent  with  the  cost  sharing  guidelines.   The
     degree  of cost sharing will be a discriminator in  the
     evaluation  process as described further  in  paragraph
     11, Evaluation Factors, this Appendix.

     (2)   The budget section of the proposals shall include
     a budget breakdown by Government fiscal year (October 1
     to  September  30) for each year of the proposed  work.
     The budget summary shall be presented in Budget Summary
     Form  as described in Appendix  C, CAN Proposal Format.
     The detailed computations requested in addition to this
     form  will be used by the Government to evaluate  costs
     as  to  reasonableness, allowability, and allocability.
     The  total budget amount shall also be entered  in  the
     proposal summary pages.

     (3)   Direct-labor costs shall be segregated by program
     element  (e.g.,  avionics, propulsion)  with  estimated
     hourly  or  monthly rates, number of months, and  total
     dollar  amounts  for  each.  Indirect  costs  shall  be
     explained  to an extent that will allow the  Government
     to understand the basis of the estimates.

     (4)   Each  significant category regarding other  costs
     shall  be  detailed, explained, and substantiated.  For
     example,   proposals  for  equipment  purchases   shall
     specify  the  type of equipment, number of  units,  and
     unit  cost.  Requested travel allowances shall  include
     the  destination, number of travelers, number of  days,
     and the total cost per trip.

     (5)   Proposals should contain cost and technical parts
     in  one  volume;  do  not  use separate  OconfidentialO
     salary  pages.  As  applicable, include  separate  cost
     estimates  for  salaries  and wages;  fringe  benefits;
     equipment; expendable materials and supplies; services;
     domestic  and foreign travel; ADP expenses; publication
     or  page  charges;  consultants; subcontractors;  other
     miscellaneous identifiable direct costs;  and  indirect
     costs.   List   salaries  and  wages   in   appropriate
     organizational categories (e.g., program manager, other
     scientific  and  engineering  professionals,   graduate
     students,  research  assistants,  and  technicians  and
     other  non-professional personnel). Estimate  all  work
     power data in terms of work-months or fractions of full-

     (6)    Explanatory  notes  should  accompany  the  cost
     proposal  to provide identification and estimated  cost
     of  major  capital  equipment  items  to  be  acquired;
     purposes,  estimated  number  and  lengths   of   trips
     planned; basis for indirect cost computation (including
     date  of most recent negotiation and cognizant agency);
     and  clarification of other items in the cost  proposal
     that are not self-evident.

  m.  Project  Measurement

The  proposal  should describe how the project's  management
will  define,  measure and evaluate its own progress  toward
project  success over the course of the project.   The  plan
should  include  a  definition of project success  that  the
Project Lead and Co-Leads will use to guide the effort,  and
also  include provisions for measuring progress toward  cost
savings  and reportable innovations for the benefit  of  the
relevant  industry as a whole.  Project financial  reporting
must   be  developed  to  quantitatively  track  and  report
progress during the entire period of the project.

    n.   Cooperative  Agreement  Payment  Schedule/Milestone

Proposers shall identify significant accomplishments towards
achieving   the  ultimate  objectives  of  the   cooperative
agreement,  upon the completion of which NASA  will  provide
incremental   payments.   These  will  be   called   payment
milestones.  Proposals should include payment milestones  in
terms of accomplishment, date, and amount. Generally no more
than  twelve payment milestones will be required per   year.
The first payment milestone must not preceed receipt by NASA
of the articles of collaboration including signed agreements
among all parties.

  o. Classified Information

Proposals should not contain national-security sensitive  or
classified material. However, if the proposed work  requires
access  to  or may generate such information, the  submitter
will  be  required  to  comply  with  applicable  Government
security regulations.

  p. Current and Pending Support

     (1)   Following the budget section, the proposal  shall
     contain  a  summary  of  current  and  pending  Federal
     support of all projects with substantial involvement of
     the  program manager and each key sub-manager for  whom
     support  is requested.  The format appears in  Appendix
     C.   The  information content shall include: source  of
     support,   project   title  with   grant,   cooperative
     agreement   or   contract  number,  award   amount   by
     Government  fiscal year, and total award amount,  award
     period,  level  of  effort in  person-months,  and  the
     location where the work is to be performed.

     (2)   For other current projects being conducted by the
     Principal  Investigator,  provide  title  of   project,
     sponsoring agency, and ending date.

  q. Special Matters

     (1)   Include  any required statements of environmental
     impact  of  the  work,  human subject  or  animal  care
     provisions,  conflict of interest,  or  on  such  other
     topics  as may be required by the nature of the  effort
     and   current  statutes,  executive  orders,  or  other
     current Government-wide guidelines.

     (2)   Proposers  should include a brief description  of
     the  organization,  its facilities, and  previous  work
     experience  in the field of the proposal. Identify  the
     cognizant  Government audit agency, inspection  agency,
     and    administrative   contracting    officer,    when

7.   Length

Unless  otherwise specified in the CAN, every effort  should
be   made   to   keep  proposals  as  brief   as   possible,
concentrating  on  substantive  material  essential  for   a
complete  understanding  of the project.   Experience  shows
that  proposals should not exceed 75  pages.

.c2.8.    Joint Proposals

The  effort  contemplated  by this  CAN  may  involve  joint
efforts  among  individuals  in different  organizations  or
mutual efforts of more than one organization. Where multiple
organizations are involved, the proposal shall be  submitted
by  only  one  of  them. In this event,  it  should  clearly
describe  the  role to be played by the other  organizations
and   indicate   the   legal  and  managerial   arrangements

9.   Late Proposals

A proposal received after the date or dates specified in the
CAN  may still be considered if the selecting official deems
it  to  offer NASA a significant technical or cost reduction

.c2.10.   Withdrawal

Proposals  may  be withdrawn by the proposer  at  any  time.
Offerors  are  requested to notify NASA if the  proposal  is
funded    by   another   organization   or   other   changed
circumstances which dictate termination of evaluation.

11.  Evaluation Factors

Unless   otherwise  specified  in  the  CAN,  the  principal
elements  (of  approximately  equal  weight)  considered  in
evaluating  a  proposal  are  its  relevance  to  the  CAN's
objectives, intrinsic merit, and cost.

   a.  Evaluation  of a proposal's relevance  to  the  CAN's
objectives includes an assessment of how well proposals meet
overall  CAN objectives (business investment strategies  and
planning, operations planning and technical objectives,  and
vehicle design and analysis).

    b.  Evaluation  of  its  intrinsic  merit  includes  the
consideration  of the following factors, none  of  which  is
more important that any other:

     (1)   Overall  integrated business investment  strategy
     and planning demonstrating linkage throughout Phase  I,
     II and III.

     (2)   Overall  scientific  or technical  merit  of  the
     proposal  or unique and innovative methods, approaches,
     or  concepts  demonstrated by the  proposal,  including
     linkage throughout Phase I, II and III.

     (3)   The  offeror's capabilities, related  experience,
     facilities, techniques, or unique combinations of these
     which  are integral factors for achieving the  proposal

     (4)  The qualifications, capabilities and experience of
     the  proposed principal investigator, team  leader,  or
     key   personnel  who  are  critical  in  achieving  the
     proposal objectives.

     (5)  Overall standing among similar proposals available
     for  evaluation  and/or evaluation  against  the  known

   c.  Evaluation of the cost of a proposed effort  includes
the  consideration of the realism and reasonableness of  the
proposed cost and the relationship of the proposed  cost  to
available  funds; and the degree of Phase I cost sharing  by
the   proposer.   While  cost  sharing  may   include   cash
(including  IR&D) and in-kind contributions, the  evaluation
of  cost sharing includes consideration of the following  in
order of importance: cash, IR&D, and in-kind contributions.

.c2.12.   Cancellation of CAN

NASA  reserves  the right to make no awards under  this  CAN
and,  in  the  absence of program funding or for  any  other
reason,  to cancel this CAN by having a notice published  in
the  Commerce Business Daily. NASA assumes no liability  for
canceling the CAN or for anyoneOs failure to receive  actual
notice  of  cancellation. Cancellation may  be  followed  by
issuance  and synopsis of a revised CAN, since amendment  of
the CAN is normally not permitted.

     (2)      Notify  the  employer  of  any  criminal  drug
