This action would codify current statutory requirements mandated by the U.S. Commercial Space Launch Competitiveness Act of 2015 (CSLCA), and provide greater clarity to affected industry and the public. Specifically, this rulemaking would update definitions relating to commercial space launch and reentry vehicles and occupants, as well as to implement clarifications to financial responsibility requirements. In addition, CSLCA would enable commercial space applicants to retain experimental permits despite issuance of a license. This rulemaking would update FAA regulations to be consistent with current statutory requirements under CSLCA. In doing so, this rulemaking would provide increased clarity for industry and other stakeholders, such as applicants seeking licenses for space flight operations involving government astronauts, currently required to adhere to the statute, resulting in a possible cost savings that will be clarified as the rule develops.
