Commercial Space FAA Should Examine How to Appropriately Regulate Space Support Vehicles U S Governtment Accountability Office

Company officials GAO interviewed identified potential uses for "space support vehicles"-which include a variety of aircraft from high-performance jets to balloons and the aircraft portion of a hybrid launch systems (a vehicle that contains elements of both an aircraft and a rocket-powered launch vehicle)-but the size of the market for these uses is unclear. Company officials said they plan to use space support vehicles to train spaceflight participants and to conduct research in reduced gravity environments. For example, some company officials said they would like to use high-performance jets to train future spaceflight participants by exposing them to physiological and psychological effects encountered in spaceflight. Other company officials said they would like to use space support vehicles to research how objects or people react in reduced gravity environments. It is difficult to know the size of the market for spaceflight training and research as GAO found no studies on these markets. However, stakeholders said they expect interest in research to increase.
