§ 1214.813 - Computation of sharing and pricing parameters.

(a) General. (1) Computational procedures as contained in the following subparagraphs of this paragraph of this section shall be applied as indicated. The procedure for computing Shuttle load factor, charge factor, and flight price for Spacelab payloads replaces the procedure contained in the Shuttle policy.

(2) Shuttle charge factors as derived herein apply to the standard mission destination of 160 nmi altitude, 28.5° inclination. Customers shall reimburse NASA an optional services fee for flights to nonstandard destinations.

(3) The customer's total Shuttle charge factor shall be the sum of the Shuttle charge factors for the customer's individual (dedicated, complete, or shared) elements, with the limitation that the customer's Shuttle charge factor shall not exceed 1.0.

(4) Customers contracting for pallet-only payloads are entitled to locate minimal controls as agreed to by NASA in a pressurized area to be designated by NASA. There is no additional charge for this service.

(5) NASA shall, at its discretion, adjust up or down the load factors and load fractions calculated according to the procedures defined in this section. Adjustments shall be made for special space or weight requirements which include, but are not limited to:

(i) Sight clearances, orientation, or placement limits.

(ii) Clearances for movable payloads.

(iii) Unusual access clearance requirements.

(iv) Clearances extending beyond the bounds of the normal element envelope.

(v) Extraordinary shapes.

(b) Definitions used in computations—(1) LC = Chargeable payload length, m. The total length in the cargo bay occupied by the customer's experiment and the Spacelab element(s) used to carry it.

(2) WC = The weight of the customer's payload and the customer's pro rata share of the weight of NASA mission-peculiar equipment carried to meet the customer's needs, kg.

(c) Dedicated-shuttle spacelab flight (1-day mission). The total reimbursement is as defined in §1214.804(e)(3).

(d) Dedicated-pallet flight (1-day mission). (1) The Shuttle load factors and charge factors for dedicated-pallet flights are shown in table 1. Subject to other STS Spacelab structural limits, customers are entitled to utilize the payload weight capability of the pallets as indicated in table 1. Payload weights in excess of those shown are subject to NASA approval and may entail optional services charges.

¹Three pallets requiring the “1+1+1” configuration shall be flown on a dedicated flight basis [See §1214.804(a)].

(2) Total reimbursement. The customer's total reimbursement is as defined in §1214.804(f)(3).

(e) Dedicated FMDM/MPESS flight (1-day mission)—(1) Shuttle charge factor. The computed charge factor for dedicated FMDM/MPESS flights is defined as:

(ii) The minimum value of LC is based on the element length, plus clearances, and is 1.18 m.

(3) Total reimbursement. The customer's total reimbursement is as defined in §1214.804(f)(3).

(f) Complete pallets (7-day mission). (1) The Shuttle load factor and charge factor for a complete pallet are 0.198 and 0.228, respectively, and its payload weight capability is 2,583 kg. Subject to other STS or Spacelab structural limits, customers are entitled to utilize this payload weight capability. Payload weight in excess of 2,583 kg is subject to NASA approval and may entail optional service charges.

(2) Total reimbursement. The customer's total reimbursement is as defined in §1214.804(g)(3).

(g) Shared elements (7-day mission)—(1) Spacelab load fractions and Shuttle load factors—(i) Pallet. Spacelab load fraction is the greater of:
