This rulemaking arose from work by the National Space Council that led to Space Policy Directive-2 (SPD-2) in May 2018, directing the U.S. Department of Transportation to streamline the regulations governing commercial space launch and reentry licensing. Part 450 consolidates multiple regulatory parts to create a single licensing regime for all types of commercial space flight launch and reentry operations, and replaces prescriptive requirements with performance-based criteria.
