NASA POLICY ON SHUTTLE FLIGHT ELIGIBILITY ANNOUNCED

NASA Policy for Payload Specialists and Space Flight Participants

A.  General

    1.  The Challenger accident marked a major change in the 
U.S. outlook and policies with respect to the flight of other 
than NASA astronauts.  NASA and interested external parties, 
domestic and international, must reexamine previous 
understandings, expectations, and commitments regarding flight 
opportunities in light of the new policies now being enunciated.

    2.  NASA policies and their implementation recognize that:

        --every flight of the Shuttle involves risks;

        --flight opportunities will now generally be limited
          to professional NASA astronauts and payload
          specialists essential for mission requirements, and

        --top priority must be given to:

          .  establishing, proving, and maintaining the
             reliability and safety of the Shuttle system,

          .  timely and efficient reduction of the backlog
             of high priority scientific and national
             security missions, and
          
          .  maximum utilization of the Shuttle
             capacity for primary and secondary payloads
             that require transportation to or from orbit by
             the Space Shuttle.

    3.  All Shuttle flights will be planned with a minimum NASA 
crew of five astronauts (commander, pilot, and three mission 
specialists).  When payload or other mission requirements define 
a need and operational constraints permit, the crew size can be 
increased to a maximum of seven.  Any such additional crew 
members must be identified at least 12 months before flight and 
be available for crew integration at 6 months.

    4.  NASA policy and terminology are revised to recognize two 
categories of persons other than NASA astronauts, each of which 
requires separate policy treatment.  They are:

       a.  "Payload Specialists," redefined to refer to persons 
other than NASA astronauts (commanders, pilots, and mission 
specialists), whose presence is required on board the Space 
Shuttle to perform specialized functions with respect to 
operation of one or more payloads or other essential mission 
activities.

       b.  "Space Flight Participants," defined to refer to 
persons whose presence on board the Space Shuttle is not required 
for operation of payloads or for other essential mission 
activities, but is determined by the Administrator of NASA to 
contribute to other approved NASA objectives or to be in the 
national interest.

B.  Payload Specialists

    Payload specialists may be added to shuttle crews when more 
than the minimum crew size of five is needed and unique 
requirements are involved.  In the case of foreign-sponsored 
missions and payloads, the need and requirements for payload 
specialists will be negotiated and mutually agreed between the 
foreign sponsors and NASA.  The selection process for additional 
crew members to meet approved requirements will first give 
consideration to qualified NASA mission specialists.  When 
payload specialists are required they will be nominated by the 
appropriate NASA, foreign, or other designated payload sponsor.  
In the case of NASA or NASA-related payloads, the nominations 
will be based on the recommendations of the appropriate 
Investigator Working Group (IWG).

C.  Space Flight Participants

    NASA remains committed to the long-term goal of providing 
space flight opportunities for persons outside the professional 
categories of NASA Astronauts and Payload Specialists when this 
contributes to approved NASA objectives or is determined to be in 
the national interest.  However, NASA is devoting its attention 
to proving the Shuttle system's capability for safe, reliable 
operation and to reducing the backlog of high priority 
missions.  Accordingly, flight opportunities for Space Flight 
Participants are not available at this time.  NASA will assess 
Shuttle operations and mission and payload requirements on an 
annual basis to determine when it can begin to allocate and 
assign space flight opportunities for future Space Flight 
Participants, consistent with safety and mission 
considerations.  When NASA determines that a flight opportunity 
is available for a space flight participant, first priority will 
be given to a "Teacher in Space" in fulfillment of space 
education plans.
