Office of Commercial Space Transportation

The Office of Commercial Space Transportation (generally referred to as FAA/AST or simply AST) is the branch of the United States Federal Aviation Administration (FAA) that approves any commercial rocket launch operations — that is, any launches that are not classified as model, amateur, or "by and for the government" — in the case of a U.S. launch operator and/or a launch from the U.S. == History == With the signing of Executive Order 12465 on February 25, 1984, President Reagan designated the Department of Transportation to be the lead agency for commercial expendable launch vehicles. This selection occurred following an interagency competition between the Departments of Commerce and Transportation to be the lead agency.
