Self-driving cars are pretty cool. Really, who wouldn’t want to spend their daily commute surfing social media, chatting with friends or finishing the Netflix series they were watching at 4 am the night before? It all sounds virtually utopian. But what if there is a dark side to self-driving cars? What if self-driving cars kill the jobs? ALL the jobs?

In this video series, the Galactic Public Archives takes bite-sized looks at a variety of terms, technologies, and ideas that are likely to be prominent in the future. Terms are regularly changing and being redefined with the passing of time. With constant breakthroughs and the development of new technology and other resources, we seek to define what these things are and how they will impact our future.

It has been more than a decade since the Concorde was retired from service, and since then no passenger aircraft has exceeded the speed of sound. That might change in the not-too-distant future, thanks to a project from NASA and industry partner Lockheed Martin Corporation. The agency is close to testing its design for Quiet Supersonic Transport, or QueSST, which could lead to passenger jets that can again reach supersonic speeds.

The Concorde was never seen as a major commercial success — more of a vanity project for the few European airlines that operated the planes. The nature of supersonic flight meant the sonic boom at ground level could shatter windows. Thus, the plane could only fly at high speeds over the ocean. The trip between Europe and New York was fast, but other routes were not feasible. When the travel industry took a downturn in 2003, the Concorde was mothballed.

QueSST technology has the potential to make supersonic air travel workable even over land, and NASA has announced that its preliminary design review is done. The aim is to build a plane that can fly at supersonic speeds without the disruptive sonic boom. NASA, with the help of Lockheed Martin, has designed and tested a scale model version of the so-called Low Boom Flight Demonstration (LBFD) experimental aircraft, known as an X-plane. This model was placed in a 6-by-8-foot supersonic wind tunnel at NASA’s Glenn Research Center. This led engineers to confirm the fuselage, wing, and engine design could allow for quieter supersonic flight.

National Electric Vehicle Sweden, which purchased Saab’s assets back in 2012, is using CES Asia to show its vision of autonomous commuting. Owning a car is out in this particular mobility vision, and vehicles not only pick you up and drop you off autonomously, they change their interiors around your needs and whims. So you enjoy a personalized ride and can make the most of every moment.

NASA’s Space Technology Mission Directorate (STMD) is keenly interested in nanotechnology – an approach that can reduce the mass and improve the performance of aerospace systems. NASA computer modeling analysis has shown that composites using carbon nanotube reinforcements could lead to a 30 percent reduction in the total mass of a launch vehicle.

“No single technology would have that much of an impact to reduce the mass of a launch vehicle by that much,” explains Michael Meador, Program Element Manager for Lightweight Materials and Manufacturing at NASA’s Glenn Research Center in Cleveland, Ohio.

Tensile properties of a carbon nanotube fiber-based composite tank were tested in a May 16 test flight.

It may have a boring name, but it is getting exciting boring done. The aptly yet ironically named company has just reached an important milestone in fulfilling Elon Musk’s newest moonshot. The visionary and entrepreneur extraordinaire took to Twitter to almost nonchalantly revealed that boring machine Godot has just completed the first segment underneath LA, while still leaving plenty of room for mystery and suspense.

Musk is anything but boring, of course, as can be seen by his ambitions turned into successful companies. His latest endeavor, however, is probably one of the most debated. It came out of the blue and, given the tongue-in-cheek name, not everyone might have taken it seriously at first. And some of those that did though Musk had finally lost it. Of course, it had its fair share of fans who shared a dream of escaping traffic congestion.

Musk’s plan to solve the traffic problem wasn’t simply to bore tunnels that cars and all sorts of vehicles would simply fill up again. Instead, the tunnels would ferry these vehicles on sleds traveling at 200 km/h. Back in April, that was nothing more than a pretty rendered animation, but last month Musk showed off a demo of just how fast that sled really is.

The Managed, Reconfigurable, In-space Nodal Assembly (MARINA), developed by MIT graduate students, recently took first place at NASA’s Revolutionary Aerospace Systems Concepts-Academic Linkage Design Competition Forum. MARINA is designed as a habitable commercially owned module for use in low Earth orbit that would be extensible for future use as a Mars transit vehicle.
