Relating to space flight activities.

HB 4660 establishes that space flight activities in Texas fall under both federal and state jurisdiction, prohibiting counties, municipalities, or other local entities from banning or regulating these activities (except as specified in Section 61.132 of the Natural Resources Code). The bill specifically applies to counties bordering the Gulf of Mexico with FAA-approved spaceports and smaller municipalities (under 150,000 population) that have beach access plans. It requires advance notice to local governments for launch dates between 8 a.m. and 5 p.m. (to the municipality) or 5 p.m. to 8 a.m. (to the commissioners court), and allows temporary beach closures near launch sites for public safety during those dates. The bill does not create new regulations but clarifies local governments' limited authority over space flight activities near coastal areas.
