DESC: NASA/MSFC plans to issue a Request for Offer (RFO)for systems
requirements and a systems design of a logistics resupply service
to the International Space Station (ISS). This in support of
the Alternate Access to Station (AAS) element of the Second
Generation Reusable Launch Vehicle Program.

This effort is
approximately one year in length to assess a logistics resupply
service concept definition to ISS. This service concept and
service plan will be part of a process used by NASA to potentially
procure a commercial service for alternate access to station.
The ISS Logistics Resupply Service concept definition should
include a systems design and operations concept capable of
transporting cargo from the surface of the Earth to the ISS
requiring a launch vehicle and an orbital transfer vehicle
with cargo carrying capability.

It is desirable but not mandatory
that the flight system be capable of returning cargo, intact,
from the ISS to Earth. The systems design and service plan
should address the launch vehicle, launch facilities, orbital
transfer vehicle, transportation to/from ISS of the orbital
rendezvous vehicle payload, all necessary subsystems, and a
service plan with an estimated cost to implement a follow on
service contract.

The maturity level of the systems requirements
and systems design at the end of the contract period should
be such that future efforts could begin with the intiation
of a preliminary design. Additionally, this RFO will ask for
key enabling technology development required to implement a
Logistics Resupply Service. Optionally, submittals may propose
candidates for future NASA funded technology development projects.

A DRAFT of the Statement of Work is attached for review and
comments. Comments shall be submitted no later than November
21, 2001. The Government will not respond to questions or comments,
but will consider them prior to issuing the RFO.

The anticipated
release date of the RFO is on or about December 17, 2001 with
an anticipated offer due date of on or about February 1, 2002.

Multiple awards of firm-fixed price contracts are being considered.
This is not a small business set-aside; however, for the purpose
of developing subcontracting baselines, any proposal submitted
by large businesses, universities and non-profit organizations
shall include a small business set-aside of at least 25%. Of
the 25%, a minimum of 8% for small disadvanged businesses,
4% for woman owned small businesses, 2% for HUBZone small business
concerns, 1% for veteran owned small businesses and 1% for
historically black colleges and universities and other minority
institutions has been established.

This procurement shall be
conducted utilizing Best Value Selection (BVS), which seeks
to select an offer based on the best combination of price and
qualitative merit (including past performance) of the offers
submitted and reduce the administrative burden on the offerors
and the Government.

The Government does not intend to acquire
a commercial item using FAR Part 12. See Note 26. The NAICS
Code and Size Standard are 541710 and 1,000, respectively.
The DPAS Rating for this procurement is DO-C9.

The provisions
and clauses in the RFO and model contract are those in effect
through FAC 97-27. All qualified responsible sources may submit
an offer which shall be considered by the agency. An ombudsman
has been appointed — See NASA Specific Note “B”.

The solicitation
and any documents related to this procurement will be available
over the Internet. These documents will be in Microsoft Office
97 format and will reside on a World Wide Web (WWW) server,
which may be accessed using a WWW browser application. The
Internet site, or URL, for the NASA/MSFC Business Opportunities

The ISS normally
utilizes the Space Shuttle or internationally contributed foreign
launch systems to deliver cargo to the ISS. The foreign launch
systems currently baselined for use for re-supply are the Russian
Space Agency (RSA) Progress, the European Space Agency (ESA)
Automated Transfer Vehicle (ATV), and the Japanese National
Space Development Agency (NASDA) H II Transfer Vehicle (HTV).

NASA is interested in studying potential augmentation of these
re-supply methods with a domestic capability utilizing commercial
providers to meet ISS needs. This augmentation is envisioned
to enhance ISS operability, meet station needs, or be used
in the event currently baselined delivery methods are unavailable.
MATERIAL PROVIDED At Authority to Proceed (ATP), NASA will
provide the contractor with a previously defined set of ISS
Logistics Resupply requirements. These logistics resupply requirements
will define payloads for Design Reference Missions (DRM), and
include the mass, volume, environmental constraints, hazard
levels, and frequency of payload delivery to orbit. NASA will
also provide the contractor with an estimate of a rapid response
flight time needed to deliver small payloads to orbit. NASA
will provide other ISS documentation as required.


Logistics Resupply Service shall include a systems design concept
and operation concept capable of transporting cargo from the
surface of the Earth to the ISS. It is desirable, but not mandatory
that the flight system be capable of returning cargo, intact,
from the ISS to Earth. The maturity level of the systems design
and operations concept should be such that a follow on effort
could begin with the initiation of a preliminary design. Innovative
practices and contractor expertise should be employed in the
development of a concept for this Logistics Resupply Service.
The proposed Logistics Resupply service should define a concept
that includes autonomous rendezvous and proximity operation
for transfer of items to the ISS.

The contractor shall provide
a service plan with a cost estimate to develop and implement
a follow on service contract. The Logistics Resupply Service
concept shall also include an assessment of the contractor’s
ability to meet the heavy payload mission, incremental payload
mass below the heavy mission and light payload missions designed
for a rapid response. The systems design shall be compatible
with ISS requirements for visiting vehicles, SSP-50235 Interface
Definition Document for International Space Station Visiting
Vehicles. Additionally, the contractor shall define key enabling
technologies required to implement their concept. Optionally,
the contractor may propose candidates for future NASA funded,
AAS enabling technology development projects. Such technology
development projects shall not be proprietary in nature due
to the desire of the government to openly share technologies
that could improve operating systems or enable commercial capabilities.
