NASA’s X-59 experimental aircraft completed a series of envelope-expansion maneuvers over the Mojave Desert, including roller-coaster climbs, bank-to-bank rolls, flutter tests, and gear deployment, to validate stability, control, and structural margins for its quiet supersonic design aimed at enabling overland flight without a loud sonic boom.
Dyson launches a travel-sized Supersonic hair dryer for $299.99, claiming a 32% smaller, 25% lighter design with automatic voltage adaptation and backwards compatibility with existing attachments; it’s part of Dyson’s broader hair-gadget lineup and follows a 2024 pro-focused update as the brand continues to push its hair tech ecosystem.
NASA’s experimental X-59 supersonic jet ended its second flight after nine minutes due to a cockpit warning, cutting the planned one-hour mission short. NASA said the data collected on systems and handling— aided by a camera-based cockpit display instead of a traditional windscreen—remains valuable as the program pushes toward higher speeds and muffled sonic booms for over-land flights, with more than 100 flights planned to advance the project.
NASA's X-59 Quiet Supersonic aircraft, built with Lockheed Martin, is preparing for its second test flight at NASA's Armstrong Flight Research Center in California. After its first flight in October 2025, the mission will have the aircraft take off from Armstrong, fly for about an hour, reach up to 20,000 feet and roughly 260 mph, and progressively fly faster and higher to test its reduced-boom sonic concept intended to enable overland supersonic flight.
Physicists show that tape screams due to a train of fast, sideways fractures in the adhesive during stick-slip peeling. These transverse fractures race at 250–600 m/s, creating a tiny vacuum between tape and glass that collapses and launches weak shocks into the air; edge-origin shocks were confirmed by timing data, with the phenomenon detailed in Physical Review E.
A new Physical Review E study shows the tape’s screeching when peeled arises from a train of transverse cracks that travel faster than sound in air and generate a series of shock waves as they reach the tape edge, confirmed by synchronized high-speed imaging and audio measurements.
Lockheed Martin's X-59, a quiet supersonic aircraft developed with NASA, successfully completed its first flight, marking a significant step toward enabling faster, quieter commercial supersonic travel by reducing sonic booms and expanding flight over land.
NASA's X-59 Quiet Supersonic Technology aircraft successfully demonstrated in wind tunnel tests that its design can scatter shock waves to produce a muted sonic thump instead of a loud sonic boom, paving the way for quieter supersonic travel and a first flight planned for this year.
NASA and JAXA tested a scale model of the X-59 aircraft in a Japanese wind tunnel to assess noise levels and validate predictions for quieter supersonic flight, a key step toward developing commercial quiet supersonic airliners.
NASA's X-59 aircraft, developed with Lockheed Martin, aims to revolutionize supersonic travel by reducing the disruptive sonic boom to a quieter 'sonic thump.' The aircraft, featuring a unique elongated nose, is designed to manage shockwaves and spread them out, minimizing noise impact on the ground. The X-59 incorporates parts from various aircraft to save costs and relies on advanced computational technology for its design. Scheduled for test flights next year, the project seeks to gather data to potentially influence future commercial supersonic travel regulations.
The Concorde was a supersonic passenger jet that flew from 1976 to 2003, capable of reaching speeds over twice the speed of sound, with a record flight time between New York and London of under three hours. Its speed was achieved through a combination of a sleek, aerodynamic design, delta wings, and powerful turbojet engines with afterburners. However, the high fuel consumption and associated costs, along with incidents like the Air France Flight 4590 crash, led to its commercial downfall.
NASA has successfully fired up the engines of its X-59 Quiet Supersonic Technology (Quesst) aircraft, designed to produce a quieter "sonic thump" instead of a traditional sonic boom. This innovation aims to make supersonic flight over land feasible by reducing noise levels to 75 perceived loudness decibels, akin to a car door slam. The X-59, developed with Lockheed Martin, features a unique design with a long nose and external cameras for navigation, and is set to undergo further testing to establish acceptable noise standards for future supersonic travel.
The Concorde, a revolutionary supersonic plane, failed due to a combination of factors including poor business decisions, restrictions on flight routes, and a devastating crash in 2000. Despite its impressive speed and luxurious amenities, the Concorde's fuel inefficiency and loud sonic boom limited its operations. With a limited capacity of 109 passengers, tickets were expensive, costing $12,000 for a round trip across the Atlantic. The last Concorde flight took place in 2003, marking the end of an era in aviation.
