NASA's X-59 moves under its own power
NASA determined that its experimental X-59 aircraft can move under its own power following a test on July 10, 2025. The success of the test could lead to quieter supersonic aircrafts. Photo by Carla Thomas/NASA July 22 (UPI) -- NASA's quest for a quieter supersonic jet passed an early test after its X-59 aircraft was able to taxi at low speed at a manufacturing plant in California. The space agency on Tuesday announced the latest milestone for NASA's X-59 that is part of its Quesst mission to test the possibility of a supersonic aircraft with more muted sonic booms that will allow less noisy flights over populated areas. The X-59 was able to move under its own power during the test that took place last week, taxiing across the runway at the U.S. Air Force Plant 42 in Palmdale, Calif. As the aircraft taxied, engineers and flight crews observed the X-59 to evaluate its steering, braking and other important functions. The test was one of the final hurdles for the X-59 before its first flight, according to the agency. NASA engineers began test-firing the single-engine experimental aircraft at a Lockheed Martin facility last fall to see if its systems are functional. NASA plans to fly the X-59 between residential areas in 2026 and ask residents about the noise it produces while exceeding the speed of sound. If the X-59 works as intended it will produce a soft thud instead of the loud booms associated with sonic aircrafts. The aircraft has no windshield because its pilot can't see over it, as well as delta-shaped wings with a span of 29.5 feet and has a maximum takeoff weight of 32,300 pounds -- lighter than many commercial planes. Following the successful test, NASA engineers will gradually increase the X-59's taxing speed stopping short of where it would take off, according to the agency. Data from the X-59 will be shared with U.S. and international regulators to develop new regulations on noise threshold for commercial supersonic land flights.

NASA's supersonic X-59 jet that could slash NYC-London flight time in half taxis closer to take off
Breakfast in New York, midmorning snack in London. Taxi tests are underway on a highly anticipated supersonic plane designed to quietly break the sound barrier — and slash flight time between New York and London in half. The X-59 jet, dubbed the 'son of Concorde,' is one step closer to takeoff after the experimental aircraft taxied on a California runway at low speed using its own power for the first time on July 10, NASA said in a press release. The ground maneuvers at the US Air Force's Plant 42 in Palmdale mark the final series of trials for the 100-foot-long, 30-foot-wide jet before its maiden voyage, which is slated for sometime this year, according to the space agency. 3 NASA's X-59 quiet supersonic aircraft taxiing on a runway.

The high-tech plane, unveiled by NASA and Lockheed Martin last year, is the centerpiece of the space agency's QueSST mission to produce a quieter sonic boom for communities below and revolutionize air travel, potentially cutting transit time down significantly for commercial flights. It could possibly fly from New York to London flight in three and a half hours, the agency previously said. 3 NASA's X-59 quiet supersonic aircraft conducting its final tests before its maiden voyage.

Supersonic flights have been banned in the US and other countries for the past half-century due to the thunderous sound generated when planes exceed the speed of sound — 767 miles per hour. 3 The aircraft is expected to revolutionize air travel. NASA But the X-59's thin, tapered nose is expected to break up shock waves that would cause the high-speed roar on a conventional aircraft, NASA previously boasted. The latest innovation will succeed the British Airways Concorde, which reached speeds of around 1,350 miles per hour and completed its fastest transatlantic flight in just under three hours on Feb. 7, 1996. The aircraft, which debuted in 1976, was plagued by costly maintenance and a fatal 2000 crash. It was retired from commercial service in 2003.
