摘要：	Over the 1900s and into the 2000s, both aeronautics and from the mid 20 th century, space faring successfully developed new technological capabilities that favorably altered nearly every aspect of human society. Air transport largely replaced rail and ship passenger traffic and greatly reduced travel time. Positional Earth utilities in space including telcom writ large greatly aided the buildout of the transformational IT revolution. Both aero and space transformed national security. Going forward, the outlook in civilian aeronautics includes artificial intelligence (AI), emission less transport aircraft for climate, and a new capability in small electric vertical takeoff and landing (VTOL) aircraft for both service and personal air vehicles. After a century of development, projections indicate personal air vehicles (PAVs) will be deployed as autonomous, safe, quiet, and affordable replacements for automobiles. The societal impacts of the latter are potentially massive, including a new aero market estimated at over $2T. PAVs also provide the ability to live anywhere such as off roads, provide huge societal savings and reduce countryside impacts with regards to roads, bridges, and other auto infrastructures along with increasingly replacing scheduled domestic airline service. Personal air vehicles are a literal major revolution in personal mobility [Refs. 7 – 10]. The recent and ongoing reductions in the cost of space access are slated to enable development of commercial deep space, beyond geostationary orbit (GEO) to the Moon, Mars, etc. There are technological developments underway that could enable humans to become a two-planet society via colonization of Mars, with the development of a viable Martian economy [Refs. 11 – 16]. These envisaged developments in aeronautics and space will require ideation, research, and maturation of viable solution spaces for several barrier issues. For aeronautics, these issues include an autonomous air traffic management (ATM) system for the projected tens of millions of flying things vice the current tens of thousands, advanced batteries including lithium-air at seven times that of lithium ion, and advanced aerodynamics to double transport lift-to-drag ratio for emission less flight. For space, affordable approaches are needed to clean up the increasingly severe problem of space debris and provide galactic cosmic radiation (GCR) protection for humans, along with serious cost reductions for humans to Mars. For climate, there is a need to determine the detailed physics, chemistry, etc. of cloud micro physics. Aerosols are equal in magnitude and opposite in sign to carbon dioxide (CO 2 ) regarding effects on climate. Because aerosols involve extremely complex processes, they require far more detailed study for improved climate projections. In addition to these barrier issues for space and aeronautics, there are several serious barrier issues common to both. They include cost, energetics, safety, artificial intelligence (AI)/autonomy, the developing AI/robotic technological competition regarding onsite human aeronautics and space, and tele-everything, immersive presence, the virtual age, etc. The present report examines these barrier issues, their putative solution spaces, and their potential major combinational societal impacts – altering/expanding both aeronautics and spacefaring and enabling large new markets, lowering costs, improving human health and safety, and altering societal lifestyles.
