14 CFR 1214.106 - Minor delays.
NASA will attempt to accommodate customer requested minor launch delays. Such delays will normally be requested just prior to launch. Except for potential optional service charges, delays up to 72 hours can normally be accommodated at no charge. This 72-hour period is shared by all customers on a particular flight. The basis of proration will be established in the launch agreement. Delays beyond 72 hours will require NASA's approval and will result in an additional charge as established in the launch agreement.
