Summary

The Secretary of Transportation must work with the Defense Secretary and the NASA Administrator to make sure a launch or reentry that the government has given a date for is not blocked from using a U.S. government launch site, reentry site, or property, unless there is an urgent national need. The Defense Secretary or the NASA Administrator, together with the Transportation Secretary, decides if that urgent need exists, and that decision cannot be passed to someone else. If a licensee or transferee is blocked for that reason, they must not pay the government for the launch or reentry that was stopped. Within 7 days after such a decision, the Defense Secretary or the NASA Administrator must send Congress a report saying why it happened and when the payload will be launched or returned.

(a)General.—
With the cooperation of the Secretary of Defense and the Administrator of the National Aeronautics and Space Administration, the Secretary of Transportation shall act to ensure that a launch or reentry of a payload is not preempted from access to a United States Government launch site, reentry site, or launch property, except for imperative national need, when a launch date commitment or reentry date commitment from the Government has been obtained for a launch or reentry licensed under this chapter. A licensee or transferee preempted from access to a launch site, reentry site, or launch property does not have to pay the Government any amount for launch services, or services related to a reentry, attributable only to the scheduled launch or reentry prevented by the preemption.
(b)Imperative National Need Decisions.—
In consultation with the Secretary of Transportation, the Secretary of Defense or the Administrator shall decide when an imperative national need requires preemption under subsection (a) of this section. That decision may not be delegated.
(c)Reports.—
In cooperation with the Secretary of Transportation, the Secretary of Defense or the Administrator, as appropriate, shall submit to Congress not later than 7 days after a decision to preempt under subsection (a) of this section, a report that includes an explanation of the circumstances justifying the decision and a schedule for ensuring the prompt launching or reentry of a preempted payload.
