Relating to liability protections for commercial space flight and exploration.

HB 4157 creates legal protections for commercial space flight companies by establishing requirements for liability waivers. It defines "space flight participant" as non-crew individuals aboard spacecraft and mandates that waivers must be in writing, printed in 10-point bold type, and signed by participants (including heirs and representatives). The bill also recognizes federal waivers under 14 C.F.R. § 440.17 as enforceable in Texas, covering contractors and customers. This law applies only to incidents occurring on or after its September 1, 2025 effective date.
