NASA's X-59 Jet Breaks Sound Barrier in Latest Tests

NASA's experimental X-59 jet has achieved supersonic speeds in its latest test flights, reaching Mach 1.4 (approximately 1,474 km/h) at an altitude of 16,700 meters. This milestone follows an earlier test on June 5, where the jet reached Mach 1.1 (1,147 km/h) at 13,200 meters.

Developed in partnership with Lockheed Martin, the X-59 is designed not only for speed but also for quiet supersonic flight. NASA aims to reduce the loud sonic booms typically associated with breaking the sound barrier to a mere thump, making supersonic travel more acceptable over land.

Live Science reported that further tests scheduled for later this year will focus on the aircraft's noise reduction capabilities. The current challenge lies in managing the air pressure waves created as the jet travels at supersonic speeds. These waves generate the characteristic sonic boom, which NASA is working to mitigate.

The goal is to enable supersonic flight over populated areas, a capability that has been restricted due to noise concerns. The X-59's unique design, featuring a long nose and specialized shaping, is intended to spread out the shockwaves, transforming the loud boom into a quieter sound.

Further tests planned for later this year will better demonstrate this experimental aircraft's progress in noise reduction.
