MACH Act

HR 477 (MACH Act) establishes a NASA program to facilitate commercial testing of hypersonic aircraft technology. It prohibits NASA from funding technology development (only enabling testing) and restricts partnerships with foreign entities or "entities of concern" per security definitions. NASA must coordinate with the Defense Department and FAA, develop a strategic plan within 60 days, and submit annual reports to Congress on testing activities. This directly affects commercial companies seeking to test hypersonic systems through NASA's framework.
