Relating to the regulation of certain space flight activities, including the closure of certain areas for those activities.

SB 2188 requires spaceflight operators in specific Texas counties (bordering the Gulf of Mexico with FAA-approved spaceports) and small municipalities (under 150,000 population) to submit proposed launch dates to local officials. It allows county commissioners courts or municipal governing bodies to temporarily close beaches near launch sites during designated times - Monday 8 a.m. to Friday 12 p.m., or Friday 12 p.m. to Monday 8 a.m. - to protect public safety. The bill directly affects spaceport operators and coastal communities with approved launch facilities, while prohibiting local governments from banning spaceflight activities outside these specific closure procedures. It clarifies that spaceflight regulation falls under federal and state jurisdiction, not local ordinances.
