  Subpart 1214.1_General Provisions Regarding Space Shuttle Flights of 
        Payloads for Non-U.S. Government, Reimbursable Customers
 
Sec.  1214.119  Spacelab payloads.

    (a) Special provisions. This Sec.  1214.119 establishes the special 
provisions for Spacelab services provided to Space Shuttle customers. 
Where designated, provisions of this Sec.  1214.119 supersede those of 
other portions of this document. The following five types of Spacelab 
flights are available to accommodate payload requirements:
    (1) Dedicated-Shuttle Spacelab flight (Ref. Sec.  1214.119(d)(3)).
    (2) Dedicated-pallet flight (Ref. Sec.  1214.119(d)(4)).
    (3) Dedicated-FMDM/MPESS (flexible multiplexer-demultiplexer/
multipurpose experiment support structure) flight (Ref. Sec.  
1214.119(d)(4)).
    (4) Complete-pallet flight (Ref. Sec.  1214.119(d)(5)).
    (5) Shared-element flight (Ref. Sec.  1214.119(d)(6)).
    (b) Definitions--(1) Spacelab elements. Pallets (3-meter segments), 
pressurized modules (long or short), and the FMDM/MPESS (1-meter cross-
bay structure), all as maintained in the NASA-approved Spacelab 
configuration.
    (2) Spacelab standard flight price. The price for standard services 
provided to Spacelab customers. If a customer elects not to use a 
portion of the standard services, the Spacelab standard flight price 
will not be affected. The Spacelab standard flight price is a pro rata 
share of:
    (i) The dedicated flight price as defined in Sec.  1214.102(c);
    (ii) The standard price for use of the selected Spacelab elements; 
and
    (iii) For complete-pallet and shared-element flights:
    (A) The price for 6 extra days on orbit; and
    (B) The price for 7 days of second-shift operation.
    (c) Mandatory use of dedicated-Shuttle Spacelab flight. (1) The 
customer will be required to fly under the provisions of Sec.  
1214.119(d)(3), if the customer requires exclusive use of any of the 
following:
    (i) Pressurized module (long or short).
    (ii) Three pallets in the ``1+1+1'' configuration.

[[Page 101]]

    (iii) Four pallets in the ``2+2'' configuration.
    (2) In the cases cited in paragraph (1)(i) of this section, if the 
customer requests, NASA will attempt to find compatible sharees to fly 
with the customer's payload. If NASA is successful, the customer's 
Shuttle standard flight price will be the greater of:
    (i) The dedicated flight price less reimbursements from sharees 
actually flown; or
    (ii) The computed Shuttle shared-flight price for the customer's 
Spacelab payload.
    (d) Reimbursement for standard services. (1) Customers will 
reimburse NASA an amount equal to the Spacelab standard flight price 
computed according to the following provisions:
    (2) Earnest money. For those customers required to pay earnest money 
in accordance with Sec.  1214.103(h)(1), the total earnest money payment 
per payload for Spacelab payloads (including Shuttle services) will be 
either $150,000 or 10 percent of the customer's estimated Spacelab 
standard flight price, whichever is less.
    (3) Dedicated-Shuttle Spacelab flight. (i) A dedicated-Shuttle 
Spacelab flight is a Shuttle flight flown for a single customer who is 
entitled to select the Spacelab elements used on the flight.
    (ii) In addition to the standard services listed in Sec.  
1214.119(j), the following standard services are provided to customers 
of dedicated-Shuttle Spacelab flights and form the basis for the 
Spacelab standard flight price:
    (A) Use of the full standard services of the Shuttle and the 
Spacelab elements selected.
    (B) One day of one-shift on-orbit operations.
    (C) Standard mission destinations consistent with launch criteria as 
defined in Sec.  1214.117.
    (D) The available payload operations time of two NASA-furnished 
mission specialists.
    (iii) Customers contracting for a dedicated-Shuttle Spacelab flight 
will reimburse NASA for standard services an amount that is the sum of:
    (A) The dedicated flight price as defined in Sec.  1214.102(c); and
    (B) The price for the use of all Spacelab elements used (including 
all necessary mission-independent Spacelab equipment).
    (4) Dedicated 3-meter pallets and dedicated FMDM/MPESS. (i) A 
dedicated pallet (or a dedicated FMDM/MPESS) is one that is flown for a 
single customer and includes all Spacelab hardware necessary to permit 
it to be flown on any shared flight as an autonomous payload (e.g., a 
dedicated 3-meter pallet may either be supplied with its own exclusive 
igloo or be flown without an igloo, if it requires only standard Shuttle 
services).
    (ii) In addition to a pro rata share of the standard services listed 
in Sec.  1214.119(j), the following standard services are provided to 
customers of dedicated pallets (or dedicated FMDM/MPESS) and form the 
basis for establishing the Spacelab standard flight price:
    (A) A pro rata share of the standard services listed in Sec.  
1214.115, where the basis for proration is the customer's Shuttle load 
factor as defined in Sec.  1214.119(l)(4)(i) for dedicated pallets and 
in Sec.  1214.119(l)(5)(ii) for a dedicated FMDM/MPESS.
    (B) The exclusive services of the pallet (or FMDM/MPESS) and all 
Spacelab hardware provided to support the pallet (or FMDM/MPESS).
    (C) One day of one-shift on-orbit operations.
    (D) Launch on a shared standard Shuttle flight as defined in Sec.  
1214.117.

NASA-furnished mission specialists, where the basis of proration will be 
the customer's Shuttle load factor.
    (iii) Customers contracting for a dedicated-pallet (or FMDM/MPESS) 
flight will reimburse NASA for standard services an amount that is the 
sum of:
    (A) The product of the customer's Shuttle charge factor and the 
dedicated flight price as defined in Sec.  1214.102(c); and
    (B) The price for the use of the pallet (or FMDM/MPESS) selected 
(including all necessary mission-independent Spacelab equipment).
    (5) Complete pallet. (i) A complete Spacelab pallet is one that is 
flown for a single customer, but flies with other Spacelab elements on a 
NASA or

[[Page 102]]

NASA-designated Spacelab flight and shares the common standard Spacelab 
services (e.g., shares an igloo with other pallets).
    (ii) In addition to a pro rata share of the standard services listed 
in Sec.  1214.119(j), the following standard services are provided to 
customers of complete pallets and form the basis for the Spacelab 
standard flight price:
    (A) The pallet's pro rata share of standard services listed in Sec.  
1214.115, where the basis of proration will be the customer's Shuttle 
load factor as defined in Sec.  1214.119(l)(6)(i).
    (B) A pro rata share of 7 days of two-shift on-orbit operations, 
where the basis of proration will be the customer's Shuttle load factor.

NASA-furnished mission specialists and two payload specialists, where 
the basis of proration will be the customer's Shuttle load factor.
    (G) Use of the entire volume above a pallet.
    (iii) Customers contracting for complete-pallet flights will 
reimburse NASA for standard services an amount which is the sum of:
    (A) The product of the customer's Shuttle charge factor and the sum 
of:
    (1) The dedicated flight price as defined in Sec.  1214.102(c).
    (2) The charge for 6 extra days of one-shift on-orbit operations.
    (3) The standard price for additional services required to support a 
second shift of on-orbit operations for 7 days.
    (B) The price for the use of a complete pallet, including all 
necessary mission-independent Spacelab equipment.
    (6) Shared element. (i) A shared element is a Spacelab pallet, FMDM/
MPESS, or module that:
    (A) May be shared by two or more customers on a NASA-designated 
Spacelab flight; and
    (B) Shares common standard services with other Spacelab elements on 
the same flight.
    (ii) In addition to a pro rata share of the standard services listed 
in Sec.  1214.119(j), the following standard services are provided to 
customers of shared elements and form the basis for the Spacelab 
standard flight price:
    (A) For shared pallets, a pro rata share of the standard services 
provided by a pallet. The basis of proration will be the customer's 
Spacelab load fraction as defined in Sec.  1214.119(l)(7)(i)(A).
    (B) For shared modules, a pro rata share of the standard services 
provided by a long module flown on a dedicated-Shuttle Spacelab flight. 
The basis of proration will be the customer's Spacelab load fraction as 
defined in Sec.  1214.119(l)(7)(i)(B). The type of pressurized module 
actually used to meet a customer's requirement for a shared module will 
be determined by NASA subsequent to launch agreement negotiations.
    (C) A pro rata share of the element's share of standard services 
listed in Sec.  1214.115, where the basis for proration will be the 
customer's Spacelab load fraction.
    (D) A pro rata share of 7 days of two-shift on-orbit operations, 
where the basis of proration will be the customer's Shuttle load factor 
as defined in Sec.  1214.119(l)(7)(i).

    (B) The product of the customer's element charge factor and the 
price for the use of the Spacelab element being used, including all 
necessary mission-independent Spacelab equipment.
    (e) Minor delays. The minor delay provisions of Sec.  1214.106 will 
apply only to those Spacelab payloads whose Shuttle load factor is equal 
to or greater than 0.05.
    (f) Postponement and termination. (1) A customer may postpone the 
flight of a Spacelab payload one time with no additional charge if 
postponement occurs more than 18 months before the scheduled launch 
date.
    (2) Postponement or termination fees for Spacelab payloads will 
consist of the sum of:
    (i) A fee for postponement or termination of the Shuttle launch.
    (ii) A fee for use of the Spacelab elements.
    (3) For Shuttle launch postponement and termination fee customers 
will be governed by the provisions of Sec.  1214.107 or Sec.  1214.108, 
as appropriate.
    (4) The postponement and termination fees for use of the Spacelab 
elements are computed as a percentage of the customer's price for use of 
the Spacelab elements and will be based on the table below. When

    (5) At the time of signing of the launch agreement, NASA will define 
a payload removal cutoff date (relative to the launch date) for each 
Spacelab payload to be flown on a shared flight. A customer may still 
postpone or terminate a flight after the payload's cutoff date; however, 
NASA will not be required to remove the payload before flight.
    (6) Customers postponing or terminating the flight of a payload may 
also be subject to new or additional charges for optional services 
associated with Shuttle or Spacelab support provided by NASA.
    (g) Spacelab reflight. (1) For Spacelab payloads, the provisions of 
Sec.  1214.110 apply.
    [Reserved]
    (h) Premature termination of Spacelab flights. If a dedicated-
Shuttle Spacelab flight, a dedicated-pallet flight or dedicated-FMDM/
MPESS flight is prematurely terminated, NASA will refund the optional 
services charges for planned, but unused, extra days on orbit. If a 
complete-pallet or shared-element flight is prematurely terminated, NASA 
will refund a pro rata share of the charges for planned, but unused, 
extra days on orbit to customers whose payload operations are, in NASA's 
judgment, adversely affected by such premature termination. The basis 
for proration will be the customer's Shuttle load factor.
    (i) Integration of payloads. (1) The customer will bear the cost of 
the following typical Spacelab-payload mission management functions:
    (i) Performing analytical design of the mission.
    (ii) Generating mission requirements and their documentation in the 
Payload Integration Plan (PIP).
    (iii) Providing mission-unique training and payload specialists (if 
appropriate).
    (iv) Physically integrating experiments into racks and/or onto 
pallets.
    (v) Providing payload-unique software for use during ground 
processing, on orbit or in POCC operations.

    (vii) Ensuring the mission is safe.
    (2) All physical integration (and de-integration) of payloads into 
racks and/

[[Page 104]]

or onto pallets will normally be performed at KSC by NASA. When the 
customer provides Spacelab elements, these physical integration 
activities may be done by the customer at a location chosen by the 
customer.
    (3) Except for the restrictions noted in paragraph (i)(2) of this 
section, and the implementation of paragraph (i)(1)(vii), customers 
contracting for dedicated-Shuttle and dedicated-pallet flights may 
perform the Spacelab-payload mission management functions defined in 
paragraph (i)(1) of this section. NASA will assist customers in the 
performance of these functions, if requested. Charges for this service 
will be based on estimated actual costs, or actual costs where 
appropriate, and will be in addition to the price for standard services.
    (4) For complete pallets or shared elements, NASA will normally 
perform the Spacelab-payload mission management functions listed in 
paragraph (i)(1) of this section. Charges for this service will be based 
on estimated actual costs, or actual costs where appropriate, and will 
be in addition to the price for standard services.
    (5) Integration of payload entities mentioned in paragraphs (i)(2) 
through (i)(4) of this section with NASA-furnished Spacelab support 
systems and with the Shuttle will be performed by NASA as a standard 
service for all payloads flown on customer-furnished Spacelab elements. 
Customers will be available to participate as required by NASA in these 
levels of integration. Customer equipment will be operated only to the 
extent necessary for interface verification. Customers requiring 
additional payload operation after delivery of the payload to NASA will 
negotiate such operation as an optional service.

    (v) Total reimbursement. (A) The customer's total reimbursement is 
as defined in Sec.  1214.119(d)(6)(iii).
    (B) If a customer contracts for portions of more than one element, 
the charges for the use of the elements will apply individually to each 
element used.
    (vi) Pressurized module experiment volume. Experiment volume in the 
pressurized module is defined to be the sum of the customer's payload 
volume in racks and in the center aisle.
    (A) Rack volume is defined relative to basic Air Transportation Rack 
(ATR) configurations. The customer's rack volume will be defined as the 
volume of one or more rectangular parallelepipeds (rectangular-sided 
boxes) which totally enclose the cuss payload. Width dimensions will be 
either 45.1 or 94.0 centimeters. Height dimensions will be integral 
multiples of 4.45 centimeters. Depth dimensions will be 61.2 or 40.2 
centimeters.
    (B) Center aisle space volume is defined as the volume of a 
rectangular parallelepiped which totally encloses the customer's 
payload. No edge of the parallelepiped will be less than 30 centimeters 
in length.
    (vii) Pressurized module storage volume. Storage volume in the 
pressurized module is defined as the volume of one or more rectangular 
parallelepipeds enclosing the customer's stowed payload. No edge of the 
parallelepiped(s) will be less than 30 centimeters in length.
    (viii) Pallet payload volume. Volume of the customer's pallet-
mounted payload is defined as the volume of a rectangular parallelepiped 
enclosing the pallet payload and customer-dictated mounting hardware. No 
edge of the parallelepiped will be less than 30 centimeters in length.
