NASA will host a news conference at 11 a.m. EDT Tuesday, April 3, to announce the agency’s plans for its next experimental aircraft, or X-plane, called the Low-Boom Flight Demonstrator (LBFD).
In February 2016, NASA signed a contract for the preliminary design of its LBFD concept. The agency now is ready to move forward with development and building of the aircraft, which will test new technology for quiet supersonic flight and possibly enable changes that will allow for supersonic flights over land.
The news conference will be held in the James E. Webb Auditorium at NASA Headquarters at 300 E St. SW in Washington, and also will air live on NASA Television and the agency’s website.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

“cruise at 55,000 feet at a speed of about 940 mph”
That’s a Mach number of about 1.4. For comparison, the Concord did about Mach 2 at 60,000 feet.
