After 25 test flights, NASA’s X-59 quiet supersonic experimental aircraft steadily continues to pass performance marks set by ...

NASA’s X-59 quiet supersonic research aircraft has completed 25 test flights, with its 25th flight reaching Mach 1.2. NASA says the 72-minute Aug. 21 flight from Armstrong Flight Research Center ...

For seven decades, the sonic boom has been the price of speed. Chuck Yeager shattered the sound barrier in 1947, and ever since, anyone flying over a populated area faster than Mach 1 has been ...

NASA is ramping up its X-59 supersonic aircraft testing campaign with a series of envelope expansion test flights. On April 14, the space agency stress tested the X-59, with a pilot performing a ...

NASA has already proved that its needle-nosed X-59 can move seriously fast in recent test flights. Now, the next step is to find out whether it can break the sound barrier without announcing its ...

NASA is testing the X-59, an experimental plane that was designed to exceed the speed of sound without a loud sonic boom. Credit: NASA / Carla Thomas NASA's X-59 jet has broken the sound barrier for ...

More than two decades since the Concorde supersonic airliner last took to the skies, NASA has been flying an experimental aircraft designed to replace loud sonic booms with a quieter thump equivalent ...

NASA's X-59 jet is on the verge of finally breaking the sound barrier. The X-59 is a supersonic aircraft designed with a radical elongated geometry that aims to reduce the volume of the sonic booms it ...

NASA's X-59 research plane took its first supersonic flight at the beginning of the month, and now it's demonstrated that it can reach the speed and altitude conditions it'll need to achieve for ...

NASA’s X-59 quiet supersonic research aircraft flies above mountains near NASA’s Armstrong Flight Research Center in Edwards, California, on Tuesday, May 12, 2026. NASA continues expanding the ...
