NASA’s experimental X-59 jet, which could make supersonic commercial travel a reality, has been cleared for final assembly. The X-59 Quiet SuperSonic Technology (QueSST) aircraft, designed by Lockheed Martin, could take its first flight as soon as 2021.
This is NASA’s first large-scale, piloted x-plane (or experimental aircraft) in more than three decades, and its goal is to reduce the loudness of a sonic boom to more of a sonic thump. When the long, slender jet transitions to supersonic speed, it will make about as much noise a car door closing, and since it will be flying 940 MPH at 55,000 feet, that could be essentially inaudible.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
